Answer:

Step-by-step explanation:

Put x = 9 to the equation 3x + 4y = 43

(3)(9) + 4y = 43

27 + 4y = 43 <em>subtract 27 from both sides</em>

4y = 16 <em>divide both sides by 4</em>

y = 4

Sierra says that she can simplify the side of the inequality shown by combining the terms within the parentheses but that she c

stiv31 [10]

Answer:

Yes, Sierra is correct

Step-by-step explanation:

Given

$4(y + 7) > -3 (4 + 5)$

Required

Is she correct

The right parenthesis has 4 + 5.

This can be simplified as: $4 + 5 = 9$

So, we have:

$4(y + 7) > -3 (4 + 5)$

$4(y + 7) > -3 *9$

The left parenthesis has y + 7.

This cannot be simplified because y is a variable and 7 is a number.

<em>Hence, Sierra is correct.</em>
