Answer:
The answer is 7.875
Step-by-step explanation:
You can get this answer by tuting the numbers into decimals and multiplying
6x-15y=-63
-15x+15y=90
This is because you are multiplying the first equation by a constant of 3 and the second equation by 5 so that you can have -15y and +15y which will cancel each other out.
You would multiply 50x16 being 16 ounces= 1 pound and than divide that by 10
0.15 as fraction or multiply 3/8 and 2/5
Just by comparing the plots of f(x) and g(x), it's clear that g(x) is just some positive scalar multiple of f(x), so that for some constant k, we have
g(x) = k • f(x) = kx² = (√k x)²
The plot of the transformed function g(x) = (√k x)² passes through the point (1, 4), which means
g(1) = (√k • 1)² = 4
and it follows that k = 4. So g(x) = 4x² = (2x)² and B is the correct choice.
