Solution:
<u>Note that:</u>
To find the solution to the proportion, we will need to simplify the equation (4/7 = 10/x)
- 4/7 = 10/x
- => 4x = 70
- => x = 70/4 = 35/2 = 17.5.
Hoped this helped!
For C at 7pm they sold most and at 6 am they sold less
Please write x^2, not x2.
If you stretch the graph of y=x^2 vertically by a factor of 4, the resulting graph represents the quadratic function y = 4x^2. It's still a parabola, but appears to be thinner.
This particular question is about horizontal stretching, however. Stretching the graph horizontally by a factor of 4 results in the new function g(x) = (x/4)^2. Try graphing x^2 and also (x/4)^2 on the same set of axes to observe this phenomenon.
-6x + 2y = 8
isolate the y
first add 6x to both sides
2y = 6x + 8
then divide everything by 2 to isolate the y
y = 3x + 4
Hope this helps
