Answer:
answer below
Step-by-step explanation:
I think you mean "squashed" or "stretched" vertically by a factor of 5.
f(x) is the original parabola equation
g(x) = 5f(x) is vertically stretched by a factor of 5
(x,y) -> (x , 5y)
Hello from MrBillDoesMath!
Answer:
x = 140
Discussion:
Please clarify! It appears from the diagram that x + 40 = 180 (nothing to do with parallel lines). Then
x + 40 = 180 => subtract 40 from each side
x + 40 - 40 = 180 -40
x = 140
I doubt this is what was meant. I will update this answer if you provide more info.
BTW: y = 40 degrees as alternate interior angles created by a transversal cutting parallel lines are equal.
Thank you,
MrB
Answer: 90 inches and 2.5 yards
Step-by-step explanation:
There are 12 inches in a foot. Since there are 7.5 feet, you will multiply 7.5 by 12 to get 90 inches.
7.5 x 12 = 90
There are 3 feet in a yard. Divide 7.5 by 3 to find the amount of yards.
7.5 / 3 = 2.5
Answer:
Let's understand the solution in detail.
Explanation:
Given: 5x = 3y
We can rearrange it as y = 5x / 3
Hence, we see that y ∝ x, and the equation is of the form y = kx, where k is the proportionality constant. This denotes that y varies directly with x.
Here k = 5 / 3.
Hence, the equation represents a direct variation, and the constant of variation is k = 5 / 3.
