Graph the line that passes through the points (3, -6) and (4, - 7) and determine the equation of the line.
Answer:
y=-x-3
I attached a file so you can plot the points on your own.
Answer:
Step-by-step explanation: First we need to figure out the slope. There are two ways:
Slope Intercept form:First you need to find the slope with Δy/Δx. This will plug in as
-7 - (-6)/ 4 - 3. This will simplify to -1/1, then -1. So m = -1
Now we have the equation y = -1x + b. We need to find b.
In order to do that, we need to plug in one of the points. I'm using (3,-6) but you can use whatever point. Once we plug it in, we have -6 = -(3) + b. Solve for b and you get -3. So the final equation is y = -x - 3.
Point Slope form:
Like the slope intercept form, we need to find the slope, in which case is -1. Next, we can use one of the ordered pairs again to plug it into the equation
y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex]), where [tex]y_{1}[/tex] is the y of the pair and [tex]x_{1}[/tex] is the x of the pair. You can use the other points too. The final equation once you plug it in is y -(-6) = -(x-3) or y + 7 = -(x - 4).
Hope this helps!

Higher Order Thinking The city acquired more land next
to the subdivision. If it decides to make each park 12.5 acres,
how many additional acres would the parks occupy?
Answer: 37.5 acre
Step-by-step explanation: First, let's find out how much acre there would be if there were 3 parks. Since we know our basic multiplication, 1.25 x 3 is 3.75. Next, we need to find out what 12.5 x 3 is. When you multiply 12.5 x 3 you get 37.5.
Find area of the triangle formed by x− and y−intercepts of the parabola y=4x^2−8x−5.
Answer:
7.5 unit square
Step-by-step explanation:
7.5 unit²
Step-by-step explanation:
Refer to attached
Find the y-intercept:
x = 0 ⇒ y = 4*0 - 8*0 - 5 = - 5
Find the x-intercepts:
y = 0 ⇒ 4x² - 8x - 5 = 0
4x² - 8x + 4 - 9 = 0
4(x - 1)² = 9
(x - 1)² = 9/4
x - 1 = 3/2 ⇒ x = 2.5
x - 1 = - 3/2 ⇒ x = - 0.5
We have vertices of the triangle at:
(- 0.5, 0), (2.5, 0) and (0, -5)
Base of the triangle is:
2.5 - (-0.5) = 3
Height of triangle:
0 - (-5) = 5
The area is:
A = 1/2bh
A = 1/2*3*5 = 7.5
Answer:
7.5 unit²
Step-by-step explanation:
find x and y intercepts
x = 0 ⇒ y = 4*0 - 8*0 - 5 = - 5
y = 0 ⇒ 4x² - 8x - 5 = 0
4x² - 8x + 4 - 9 = 0
4(x - 1)² = 9
(x - 1)² = 9/4
x - 1 = 3/2 ⇒ x = 2.5
x - 1 = - 3/2 ⇒ x = - 0.5
We have vertices of the triangle at:
(- 0.5, 0), (2.5, 0) and (0, -5)
Base of the triangle is:
2.5 - (-0.5) = 3
Height of triangle:
0 - (-5) = 5
The area is:
A = 1/2bh
A = 1/2*3*5 = 7.5
Solve the problem using a system of equations: The sum of two numbers is 12 and the product is 32.
[tex]\begin{cases} \stackrel{\textit{sum is twelve}}{a + b = 12}\\ \stackrel{\textit{product is 32}}{ab = 32}\\[-0.5em] \hrulefill\\ a + b = 12\\ b = 12 - a \end{cases}\qquad \implies \stackrel{\textit{substituting that in our 2nd equation}~\hfill }{a(12-a) = 32\implies 12a-a^2=32} \\\\\\ 0=a^2-12a+32\implies 0=(a-8)(a-4)\implies a= \begin{cases} 8\\ 4 \end{cases} \\\\\\ \stackrel{\textit{we know that}}{b = 12 - a}\implies b = \begin{cases} 12-8\to &4\\ 12-4\to &8 \end{cases}[/tex]
jayden wats to use square pavers that 4 inhes on each side to completely surroung his flower garden the gaen is 8 ft long and 2 feet wide. how manyu pavers should jaden buy
The number of pavers is the count of pavers that fit the garden
Jayden should buy 1 paver
The dimension of the garden is given as:
Length = 8ft
Width = 2ft
So, the area is calculated as:
Area = Length x Width
This gives
Area = 8ft x 2ft
Area = 16 square ft
The dimension of the paver is given as:
Length = 4ft
So, the area is calculated as:
Area = Length x Length
This gives
Area = 4ft x 4ft
Area = 16 square ft
The number of pavers is calculated by dividing the area of the garden by the area of the pavers.
So, we have:
[tex]\mathbf{Number = \frac{Garden}{Pavers}}[/tex]
[tex]\mathbf{Number = \frac{16ft^2}{16ft^2}}[/tex]
[tex]\mathbf{Number = 1}[/tex]
Hence, he should buy 1 paver

Here is a picture of two squares and a circle. Use the picture to explain why
the area of this circle is more than 2 square units but less than 4 square units.
Answer: This is so because, the circle does not totally cover the area defined by the four squares and this is evident in the workings below.
The area of a square is; Area = l²
Since each circle has area, A = 1 square unit.
Therefore,
Length of Each side of each square = 1 unit
This in turn is the radius of the circle given;
The area of the circle is therefore, Area = πr²
Area = (22/7) × 1²
Area = 3.142 square units
In essence, the area of the circle is less than 4 square units.

Look at the two equations: ( look at picture is you don't understand)
-3x + 6 = 21
-3x + 6 < 21
Which statement best describes the process used to solve the equations?
A.) In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.
B.) In both cases, divide by -3 on both sides, but reverse the inequality sign when doing that for the inequality.
C.) The process is exactly the same for solving the equation and solving the inequality.
D.)The process for solving the equation is entirely different from solving the inequality.
Answer:
I believe it's A) "In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality."
Step-by-step explanation:
I say this because that's essentially the first step when solving both an equation and inequality.
(In case you were wondering, the next step would be to divide -3 on both sides, in order to get x by its self.)

Eduardo is in 8th grade and gets an allowance of $10 every week from his parents. He has saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out. He sets a budget of $250 for himself.
a: How much more money does Eduardo need before he can go shopping?
b: How many months will it take Eduardo to save this much money?
c: What trade offs might Eduardo need to make if he wants to buy the clothes in exactly 3.5 months?
Answer:
He has. saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out.
Step-by-step explanation:
a. Eduardo needs $140 more before he can go shopping.
b. 3.5 months will it take Eduardo to save this much money.
c. Eduardo will need to make thoughtful decisions about how he manages his money and balances his spending with his savings goal.
a. Here, we have to find out how much more money Eduardo needs before he can go shopping, we need to calculate the difference between his budget and the amount he has saved:
Remaining money needed = Budget - Saved amount
Remaining money needed = $250 - $110
Remaining money needed = $140
So, Eduardo needs $140 more before he can go shopping.
b. To determine how many months it will take Eduardo to save $140, we can divide the remaining amount by his weekly allowance:
Number of weeks to save $140 = Remaining money needed / Weekly allowance
Number of weeks to save $140 = $140 / $10
Number of weeks to save $140 = 14 weeks
Since there are approximately 4 weeks in a month, we can convert weeks to months:
Number of months = Number of weeks / 4
Number of months = 14 weeks / 4
Number of months = 3.5 months
c. If Eduardo wants to buy the clothes in exactly 3.5 months, he will need to consider some trade-offs to meet his savings goal on time:
Cutting Expenses: Eduardo might need to cut down on unnecessary expenses, like snacks or entertainment, to save more money each week.
Additional Income: He could explore opportunities to earn extra money, such as doing chores or odd jobs for neighbors, to supplement his allowance.
Delayed Purchases: Eduardo could delay spending money on non-essential items until he reaches his savings goal. This might mean postponing purchases that can wait.
Adjusting Budget: Eduardo could reconsider his budget to see if there are any areas where he can reduce spending further to meet his goal faster.
Savings Prioritization: Eduardo could prioritize his savings over other purchases and activities for the next 3.5 months.
Ultimately, Eduardo will need to make thoughtful decisions about how he manages his money and balances his spending with his savings goal.

Answer:
Alicia
Step-by-step explanation:
First, convert the mixed fractions into improper fractions
Alicia
Distance: 5 1/2 = 11/2 = 5.5 miles
Time: 1 2/5 = 7/5 = 1.4 hours
Carlos
Distance: 8 1/8 = 65/8 = 8.125 miles
Time: 2 1/2 = 5/2 = 2.5 hours
Henry
Distance: 3 2/3 = 11/3 = 3.6 reoccuring miles
Time: 1 1/10 = 11/10 = 1.1 hours
Zoe
Distance: 4 2/3 = 14/3 = 4.6 reoccuring miles
Time: 1 3/10 = 13/10 = 1.3 hours
After that, divide the distance by the time
Alicia = 5.5 / 1.4 = 3.93 ( 3 s.f )
Carlos = 8.125 / 2.5 = 3.25
Henry = 3.6 re / 1.1 = 3.3 reoccuring
Zoe = 4.6 / 1.3 = 3.54 ( 3 s.f )
Looking at these answers, we determine which rate is the greatest
Alicia = 3.93
Carlos = 3.25
Henry = 3.3 re
Zoe = 3.54
Alicia hiked the highest rate.
