For the function y = 4x – 11, what is the output when the input is 10?

Answers

Answer 1
Answer:

= 4x - 11

x is the input, y is the output.

So if you want to know what input is needed to get an output of 10, set y to 10 and solve for x:

10 = 4x - 11

21 = 4x

x = 21/4

Step-by-step explanation:

6\sqrt3\cdot(\sqrt3)/(3)=((6\sqrt3)(\sqrt3))/(3)\n\n\text{use the associative property}\ (a* b)* c=a*(b* c)\n\n=((6)(\sqrt3\cdot\sqrt3))/(3)\n\n\text{use}\ √(a)\cdot√(a)=a\n\n=((6)(\not3))/(\not3)\qquad\text{cancel 3}\n\n=6

[6sqr(3)×sqr(3)]/3
sqr(3)×sqr(3)=sqr(3)^2=3
(6×3)/3
