If y=15 when x=5, find y when x=7, given that y varies directly with x.
Answer:
when x = 7, y = 21
Step-by-step explanation:
This is about direct variation. If y varies directly with x, then there is a constant factor of variation, k. The constant of variation can be found by ʸ⁄ₓ
k = ʸ⁄ₓ
k = ¹⁵⁄₅ = 3
Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.
y = 3x
y = 3(7)
y = 21

The equation of the line in slope Intercept form is
Answer:
y = 60x + 40
Step-by-step explanation:
It is in the form of
y = mx + b
m is the slope
b is the y intercept.
The y intercept is 40, so it will be y = mx + 40.
The slope is 60, so y = 60x + 40!

the total cost of playing an online game is $170. the base cost of the game is $50, and it costs $30 per month to play the game. The equation 170=30x+50 can be used to find the x (the number of months you play the game). How many months will you get to play the game if the total cost is $170?
Answer:
x = 4 (4 months)Step-by-step explanation:
170 = 30x + 50
Step 1: Subtract 50 from both sides170 - 50 = 30x + 50 - 50
120 = 30x
Step 2: Divide by 30 on both sides120/30 = 30x/30
x = 4
Step 3: Check170 = 30(4) + 50
170 = 120 + 50
170 = 170 ✔️
x = 4 (4 months)please help i don’t know how to do this

The price of a dress was reduce from $20 to $12. By what percentage was the price of the dress reduced?
Answer:
40%
Step-by-step explanation:
12$ out of the original 20$ = 12/20
12/20 = .6 (60%)
1=100%
if 12/20 = 60% then 100% - 60% = 40%
$20-40% is $12

The graph of g(x) = (x + 2)2 is a translation of the
graph of f(x)
v by
units.
g(x) = -x2 + 2x - 9
g(-4)
Answer:
-33
Step-by-step explanation:
g(x) = [tex]- x^{2} + 2x - 9\\[/tex]
g(-4) = [tex]- ( -4)^{2} + 2 * (-4) - 9[/tex]
= - 16 - 8 - 9 = - 33
You roll an eight-sided die. What is the chance that it will land on either a 2 or a 5? Write your answer as a fraction.
Answer:
2/8 and the simplified version is 1/4
Step-by-step explanation:
Answer:
2/8
Step-by-step explanation:
First you know that it is a eight- sided die. 2 or 5 are two numbers so it is 2/8.
you put all of the numbers and count them up on the top as numerators ex: 2/ Then the number of the sided die as the denominator.ex: 2/8 Hope this helped.

determine the vertex of y=4(x-25)2+ 91
Answer:
(25, 91)Step-by-step explanation:
y = a(x - h)² + k ← vertex form of the equation of the parabola with vertex (h, k)
So y = 4(x - 25)² + 91 means:
a = 4
x - 25 = x - h ⇒ - 25 = - h ⇒ h = 25
+ 91 = + k ⇒ k = 91
Therefore vertex is:
(25, 91)
Larry recorded his time as he ran. What was his average speed from hour 2 to hour 4?
What was his average speed from hour 4 to hour 7?
Did he speed up or slow down?
Answer:
7mph and he stayed the same
Step-by-step explanation:
Larry's average speed from hour 2 to hour 4 and from hour 4 to hour 7 is the same, 7 mi/hr, he maintained a constant speed throughout this period.
Given that Larry recorded his time as he ran
Time elapsed(hr) Distance run(mi)
2 13.5
4 27.5
7 48.5
We need to calculate his average speed,
To calculate Larry's average speed, we need to divide the total distance he ran by the time elapsed.
Let's calculate his average speed from hour 2 to hour 4 and from hour 4 to hour 7:
Average speed from hour 2 to hour 4:
Distance covered = 27.5 mi - 13.5 mi = 14 mi
Time elapsed = 4 hr - 2 hr = 2 hr
Average speed = Distance covered / Time elapsed = 14 mi / 2 hr = 7 mi/hr
Therefore, Larry's average speed from hour 2 to hour 4 was 7 miles per hour.
Average speed from hour 4 to hour 7:
Distance covered = 48.5 mi - 27.5 mi = 21 mi
Time elapsed = 7 hr - 4 hr = 3 hr
Average speed = Distance covered / Time elapsed = 21 mi / 3 hr = 7 mi/hr
Therefore, Larry's average speed from hour 4 to hour 7 was also 7 miles per hour.
Since Larry's average speed from hour 2 to hour 4 and from hour 4 to hour 7 is the same (7 mi/hr), he maintained a constant speed throughout this period. He neither sped up nor slowed down.
