Answer:
The equation for the following graph:
[tex]y = -\frac{1}{5}x[/tex]
Step-by-step explanation:
- You first need to find the slope by using the slope formula:
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
(where [tex](x_{1},y_{1})[/tex] is the first point and [tex](x_{2}, y_{2})[/tex] is the second point)
-Use the given points [tex](0,0)[/tex] and [tex](10, -2)[/tex] from the graph for the formula:
[tex]m = \frac{-2 - 0}{10 - 0}[/tex]
Then, you solve:
[tex]m = \frac{-2 - 0}{10 - 0}[/tex]
[tex]m = -\frac{1}{5}[/tex]
After you have found the slope, use the slope [tex]-\frac{1}{5}[/tex] and the first point [tex](0,0)[/tex] for the point-slope formula:
[tex]y - y_{1} = m ( x - x_{1})[/tex]
(where [tex]m[/tex] is the slope and [tex](x_{1}, y_{1})[/tex] is the first point)
[tex]y - 0 = -\frac{1}{5} ( x - 0)[/tex]
Then, you solve:
[tex]y - 0 = -\frac{1}{5} ( x - 0)[/tex]
[tex]y - 0 = -\frac{1}{5}x - 0[/tex]
[tex]y - 0 + 0 = -\frac{1}{5} - 0 + 0[/tex]
[tex]y = -\frac{1}{5}x[/tex]
So, the equation for the following graph is [tex]y = -\frac{1}{5}x[/tex] .

What is the solution to the systems of equations
Answer:
-1,9
Step-by-step explanation:
You use the equal values method to combine the two equations
-3x+6=9
then subtract 6 on both sides of the equal sign
nine minus six is 3
-3x=3
divide negative three on both sides to isolate the x value
to get....
x=-1
then plug the x value back in to find the y value
(you can plug in to one of them but I would plug into both of them just for double checking) ALWAYS CHECK YOUR WORK
3+6 is 9
9=9 check!

melissa is driving along a highway at a constant soeed of 65 mph. how long does it take her to travel 90 miles?
Answer:
1.4 hours or 83 minutes
Step-by-step explanation:
90 mi / 65 mph = 1.4 hr
Melissa will take 1.4 hour to travel 90miles at a speed of 65 mph.
What is the speed?Speed is the rate of distance covered in a particular time.
It is equal to distance/time
How to calculate time?We know that speed=distance/time
so the time will be =90/65
which will be equal to1.44 hour
Hence Melisa will take only 1.4 hour to travel 90 miles at a speed of 65 mph.

Ava and Sara both started getting an allowance 12 weeks ago, and they haven't spent a cent! They get $1 for each year of their age. Sara is 8 and gets $8 per week. Ava has $24 more than Sara. How old is Ava?
Answer:
Ava is 10 years old
Step-by-step explanation:
Sara is 8
Sara=$8 per week for 12 weeks
$8×12 weeks=$96
Ava has $24 more than Sara
x*12=96$+$24
12x=120
x=120/12
x=10
Ava's age is 10

Sierra is driving to visit her family. She wants to drive at least 500 miles today. She has already driven 248 miles and will keep driving at a constant speed of 62 miles per hour. What number of hours can Sierra drive to meet her goal of at least 500 miles? 500 ≤ 248 + 62x Both need different answers please
Answer:
4.06451 hours
note this answer is not rounded as you did not indicate round to what decimal values.
Step-by-step explanation:
Solving using equation
500 ≤ 248 + 62x
500-248 ≤ 62x
252 ≤ 62x
252/62 ≤ x
4.06451 ≤ x
Another way to solve
500-248= 252
she needs to travel 252 miles
speed = 62mph
note: speed = distance/time
therefore time= distance/speed
time = 252/62 = 4.06451
Number of hours Sierra needs to travel to meet her goal is 4.065 hours.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Sierra wants to drive at least 500 miles today.
She has already driven 248 miles.
Remaining distance is driving at a constant speed of 62 miles per hour.
Let the time needed for the remaining distance to complete is x.
Speed = Distance / Time
Distance = Speed × Time
Distance = 62x
Total distance covered = 248 + 62x
This must be at least 500.
248 + 62x ≥ 500
62x ≥ 500 - 248
62x ≥ 252
x ≥ 252 / 62
x ≥ 4.065
Hence Sierra has to drive at least 4.065 hours to meet her goal.

In ΔRST, the measure of ∠T=90°, ST = 44 feet, and TR = 84 feet. Find the measure of ∠R to the nearest tenth of a degree.
Answer:
[tex]27.6^\circ[/tex]
Step-by-step explanation:
Given:
A [tex]\triangle RST[/tex] with [tex]\angle T =90 ^\circ[/tex]
ST = 44 feet
TR = 84 feet
To find:
[tex]\angle R = ?[/tex]
Solution:
Please have a look at the attached figure for clear view of the given dimensions of the right angled triangle.
Here, we can use trigonometric formula to find out the [tex]\angle R[/tex].
We know that formula for tangent of angle [tex]\theta[/tex] is given as:
[tex]tan \theta = \dfrac{\text{Perpendicular}}{\text{Base}}[/tex]
Here, Perpendicular for [tex]\angle R[/tex] is side ST and
Base is side TR.
Putting the values in above tangent formula:
[tex]tan R = \dfrac{ST}{TR}\\\Rightarrow tan R = \dfrac{44}{84}\\\Rightarrow tan R = 0.523\\\Rightarrow \angle R = 27.6^\circ[/tex]
Hence, [tex]\angle R = 27.6^\circ[/tex] is the answer.

Which inequality represents all values of x for which the product below is defined? √ x-4•√ x+1 a. x ≥ -1 b. x ≥ 4 c. x ≥ 0 d. x ≤ 4
The inequality that represents all x values is [tex]x \ge 4[/tex]
The expression is given as:
[tex]\sqrt{x - 4} \cdot \sqrt{x + 1}[/tex]
Set the radicands to >=0
[tex]x - 4 \ge 0[/tex] or [tex]x + 1 \ge 0[/tex]
Solve for x in both inequalities
[tex]x \ge 4[/tex] or [tex]x \ge -1[/tex]
When [tex]x \ge -1[/tex], the first radicand is irrational from some x values
Hence, the inequality that represents all x values is [tex]x \ge 4[/tex]

Step-by-step explanation:
If you win the lottery, then you will need a ticket. But, if you have a ticket, it doesn't mean that you'll win the lottery.
If a number is divisible by 3. it is not necessarily divisible by 6. For example, 9 ÷ 3 = 3, but 9 ÷ 6 will not equal a whole number.
All squares are rhombuses, but not all rhombuses are squares (they need to have all interior right angles).

If AB = 3x + 5, BC = 2x + 8, and AC = 88, what is the value of x?
Answer:
x = 15
Step-by-step explanation:
AB + BC = AB
3x+5 + 2x+8 = 88
Combine like terms
5x +13 = 88
Subtract 13 from each side
5x+13-13 = 88-13
5x = 75
Divide each side by 5
5x/5 = 75/5
x = 15
Answer:
15
Step-by-step explanation:
AB + BC = AB
3x + 5 + 2x + 8 = 88
5x + 13 = 88
5x = 88 - 13
= 75/5
= 15
