Question

I'm struggling in this subject so if you'd give a step-by-step explanation that'd be great thx​

Answer 1

A. First you must start by plugging in your equation solve Y = 2(5) + 1 then you must simplify by solving your 2×5+ 1 and then you end up with Y equals 11

B. Again plug in your equation Y = 2(-5) + 1 then you must simplify by solving your 2×-5+ 1 and then you end up with Y equals -10+ one which simplifies to y = -9

I hope this helps

Answer 2

Here the equation given to us is,

${\blue{\boxed{\pink{y = 2x + 1}}}}$

Now what we have to do is, we have to put the value of x in brackets () in both the equations . Why we have to put value of x in a bracket?

This is because 2 is being multiplied by the variable x. So let's solve the equations

a) When x = 5, what is the value of y?

Put the value of x here

y = 2x + 1

y = 2(5) + 1

y = 10 + 1

y = 11

b) When x = -5, what is the value of y?

y = 2x + 1

y = 2(-5) + 1

y = -10 + 1

y = -9

ANSWERS :-

a) y = 11

b) y = -9
