Question

y=4x+5 when x is 6 and 3x+5 when x is 2

Answer 1

EXPLANATION:

We are given the equation below;

$y=4x+5$

To solve for the value of y, when x = 6, we would simply substitute for 6 instead of x into this equation as follows;

$y=4(6)+5$$y=24+5$$y=29$

Note that 6 takes the place of x, and now you have 4 times 6, in place of 4 times x.

We also have the expression;

$3x+5$

When x = 2, we can simplify this expression as follows;

$3(2)+5$$=6+5$$=11$

ANSWER:

$\begin{gathered} y=29 \\ The\text{ expression equals, }11 \end{gathered}$

The first answer is 29, the scond one is 11
