Let x = the number
Let c = the factor
You want
√(cx) = 2√x
Solve for c:
cx = 4x
c = 4
You need to multiply by 4 to double the square root. Have a great day!!
Answer:
linear function
Step-by-step explanation:
Answer:
A = -7.5 B = -17.5
Step-by-step explanation:
A + B = -25
A = B + 10
<u>Plug the second equation into the first equation:</u>
B + 10 + B = -25
2B = -35
B = -17.5
Plug that value into the first equation:
A - 17.5 = -25
A = -7.5
