Lets say we have a rectangle. if the ratio is 7:5, we can put the width as 7x, and the length as 5x (or vice versa, it doesn't really matter.) If the perimeter is solved by 2(h+w), we have 2(7x+5x)=96, or 2(7x)+2(5x)=96, which is C
Answer:
f(2) =-5
Step-by-step explanation:
We want to find the value of the function when x =2
When x=2 the y value is -5
f(2) =-5
Algebra
The graph is C, or the graph down left.
This is because the other graphs lack the same vertex.
Answer:
the answer is C
Step-by-step explanation:
because the negative needs to be on the inside not on the outside
If you would like to solve the equation - 2/5 * x + 6 = 8, you can do this using the following steps:
- 2/5 * x + 6 = 8
- 2/5 * x = 8 - 6
- 2/5 * x = 2 /*(-5/2)
x = 2 * (- 5/2)
x = - 5
The correct result would be -5.
