A line with a slope of 3 passes through the points (-8,f) and (-9,7). What is the value of f
Answer:
Step-by-step explanation:
Slope can be calculated by:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
We know M, y1, x2, and x1. We want to calculate for y2
[tex]\frac{f-7}{-8-(-9)} = 3\\\frac{f-7}{1} = 3\\f-7 = 3\\f = 10\\[/tex]
Answer: f = 10
Step-by-step explanation: Start with the slope formula.
m = y₂ - y₁ / x₂ - x₁
Plugging the given information into the
slope formula, we get 3 = 7 - f / -9 - (-8).
This simplifies to 3 = 7 - f / -1.
Multiply both sides of the equation by -1 to get -3 = 7 - f.
Solving from here, you be should be able to easily find that 10 = f.
Remember, it's very easy to check your
answer to these kinds of problems.
Since 10 = f, you can plug a 10 back in for f in the original problem.
Then check to see if the line that passes through the points
(-8, 10) and (-9, 7) really does have a slope of 3.

situation 2:  Andy has 5 discus fish.He purchases 3 more each week for $8 each
for situation 2, which rule models the total number of fish (y) as a function of the number of weeks (x)?
A) y=3x+5
B) y=4x+5
C) y=10x
D)Y=3x-5
Answer:
A
Step-by-step explanation: Because its 3 more a week and week is x and plus the 5 you already have
The rule mode for the total number of fish as the function of the number of weeks will be equal to y = 3x + 5. Hence, option A is correct.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given information in the question,
Number of Discus fish Andy have = 5
Each week Purchase = 3
Then, the equation will be,
y = 3x + 5
Here, y is the total number of discus fish and x is the number of weeks.

A piece of climbing equipment at a playground is 6 feet high and extends 4 feet horizontally. A piece of climbing equipment at a gym is 10 feet high and extends 6 feet horizontally. Which statement best compares the slopes of the two pieces of equipment?
Because Five-thirds greater-than three-halves, the slope of the climbing equipment at the gym is greater.
Because Five-thirds less-than three-halves, the slope of the climbing equipment at the playground is greater.
Because Three-fifths greater-than two-thirds, the slope of the climbing equipment at the gym is greater.
Because Three-fifths less-than two-thirds, the slope of the climbing equipment at the playground is greater.
Answer:
I think its D but I'm not that sure about it.
Step-by-step explanation:
Because three fifths less than two thirds, the slope of te climbing equipment at the playground is greater.
Answer:
A)
Step-by-step explanation:
A piece of climbing equipment at a playground is 6 feet high and extends 4 feet horizontally.
Therefore its slope = length of the equipment vertically / length of equipment horizontally
= 6/4 = 3/2 = 1.5
And, A piece of climbing equipment at a gym is 10 feet high and extends 6 feet horizontally.
Therefore slope, = 10/6 = 5/3=1.67 (approx)
Since, >
Therefore, Five-thirds greater-than three-halves, the slope of the climbing equipment at the gym is greater

If we know that 5 cups of flour is used to make 20 biscuits, how many biscuits are made with 15 cups of flour?
Answer:
60 biscuits
Step-by-step explanation:
It is 60 biscuits because if 5 cups equals 20 then 15 equals 60 biscuits. If you do the math correctly you should get this answer!
60 biscuits are made with 15 cups of flour.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Number of biscuits used to make 5 cups of flour = 20.
To find the number of biscuits that are used to make 15 cups of flour.
Use ratio property,
Since, 5 cups of flour = 20 biscuit
⇒ 1 cup of flour = 20 / 5 biscuit = 4 biscuit
Therefore,
15 cups of flour = 15 x 4 = 60 biscuit.
Hence, 15 cups of flour are required to make 60 biscuits.

In 2017, which of these represents a competitive but realistic interest rate
on a savings account?
1%
2%
3%
7%
Answer: 1%
Step-by-step explanation:
Savings accounts offer interest payments on them however they are quite easy to access which means that banks are limited in being able to use funds in savings accounts for long term loans which bring in revenue.
This therefore translates to lower interest rates being paid on the accounts and in 2017 up until now, a competitive and realistic interest rate often found in savings accounts is approximately 1%.
You and your friend go shopping with $846,375,593. (that's literally the question) You spend 250,678 dollars on shoes, 10,008 dollars on clothes, and 40,034 dollars on accesories. How much money do you both have left?
Later, your friend and you get robbed and the robber takes half of the remaining money. How much do you have left?
Later, you earn $234,485.78. How much do you and your friend now have?
This is the actual question on my homework... I have no clue how to do this... can someone please help me? 50 points!
Answer:
Initial money -->$846,375,593
You spend 250,678 dollars on shoes, 10,008 dollars on clothes, and 40,034 dollars on accesories.
$846,375,593-$250,678-$10,008-440,034 = $845,674,873
Later, your friend and you get robbed and the robber takes half of the remaining money. How much do you have left?
$845,674,873/2 = $422,837,436.5
You have $422,837,436.5 left.
Answer: Ok look at the explaination
Step-by-step explanation:
$846,375,593 - everything you spend = 846,074,873
You both have 846,074,873 after the shopping spree
To calcute how much is left after the robbery you divide the money you have left by two since the robber took half. Then your are left with 423,037,436
Then you earn money so add 234,458.78 to your 423,037,436 and you have 423,271,922
At the end you are left with $423,271,922

What is the slope of the line that passes through these two points (0, -2) and (3, -4)?
Answer:
2
Step-by-step explanation:
Use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{-4-(-2)}{3-0}[/tex] = [tex]\frac{6}{3}[/tex] = 2
The slope of the line will be "[tex]-\frac{2}{3}[/tex]".
The given points are:
[tex](x_1, y_1) = (0, -2)[/tex]
[tex](x_2, y_2) = (3, -4)[/tex]
As we know,
→ The slope of the line:
= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the values, we get
= [tex]\frac{-4-(-2)}{3-0}[/tex]
= [tex]\frac{-4+2}{3}[/tex]
= [tex]-\frac{2}{3}[/tex]

2. Find the roots of the following quadratic equations by factorisation:
100x2 - 20x + 1 = 0
Answer:
x = [tex]\frac{1}{10}[/tex]
Step-by-step explanation:
Given
100x² - 20x + 1 = 0 ← this is a perfect square
(10x - 1)² = 0, thus
10x - 1 = 0 ( add 1 to both sides )
10x = 1 ( divide both sides by 10 )
x = [tex]\frac{1}{10}[/tex]
Answer:
Step-by-step explanation:
100x^2-20x+1=0
100x^2-(10+10)X+1=0
100x^2-10x-10x+1=0
10x(10x-1)-1(10x-1)=0
(10x-1)(10x-1)=0
So roots are X=1/10,1/10

Multiple Choice:
- Rationalize the denominator
- Convert the bottom of the LHS using an identity
- Factor the RHS
- Convert tan^2(theta) + 1 of the RHS using an identity
- Find common denominators for RHS
- Cancel the 1s on LHS
Answer:
(1+cos(theta))/(1-sin^2(theta))=sec(theta)+tan^2(theta)+1
(1+cos(theta))/cos^2(theta)=sec(theta)+sec^2(theta)-1+1
(1-cos(theta))/cos^2(theta)=1/cos(theta)+1/cos^2(theta)
1-cos(theta)=cos(theta)+1
2cos(theta)=0
cos(theta)=0
theta=pi/2 and 3pi/2
I don't fully understand your question but it's quite easy to solve. As shown above, option (2) is good and you can factor the RHS but I would find it rather trivial when you can multiply both sides by cos^2(theta) just as easily. I hope this helps you.
