Answer:
9(7p) is the expression.
Step-by-step explanation:
Let's multiply 7p and 9 to get product,
→ 7p × 9
→ 9(7p)
So, the product is 9(7p).

Answer:
- a) (0,0), (-4, 1), (-1,2)
- b) None
Step-by-step explanation:
- <em>There are two ways of solving similar problems. One- substitute x and y with respective coordinates and verify if the inequalities are correct. Two- graph the lines and see if the points are in the intersection zones.</em>
- <em>We'll go with the first method. </em>
- <em>Remember both inequalities should be correct for the same point to accept it as a solution.</em>
<u>Given points </u>
<h3>a) <u>The system of inequalities</u></h3>
<u>Point (0,0)</u>
- 0 > 0 - 1 = -1 correct
- 0 < -1/2(0) + 2 = 2 - correct
- Yes
<u>Point (-4,1)</u>
- 1 > -4 - 1 = -5 - correct
- 1 < -1/2(-4) + 2 = 4 - correct
- Yes
<u>Point (-1,2)</u>
- 2 > -1 - 1= -2 - correct
- 2 < -1/2(-1) + 2 = 2.5 - correct
- Yes
<h3>b) <u>The system of inequalities</u></h3>
<u>Point (0, 0)</u>
- 0 - 2(0) = 0 ≥ 4 - incorrect
- 2(0) - 0 = 0 ≥ -1 - correct
- No
<u>Point (-4, 1)</u>
- -4 - 2(1) = - 6 ≥ 4 - incorrect
- 2(-4) - 1 = - 9 ≥ -1 - correct
- No
<u>Point (-1,2)</u>
- -1 - 2(2) = -5 ≥ 4 - incorrect
- 2(-1) - 2 = - 4 ≥ -1 - correct
- No
So here is the answer to the given question above.
If we are to use substitution method in order to solve the following system, the new equation would be <span>4x – 3(8x + 9) = –22, the answer is the second option.
Here is how I got the answer.
Let's take 8x - y = -22
So y = 8x + 22
Now, substitute the value of y to </span><span>4x – 3y = –22
and we get 4x - 3(8x +9) = -22.
Hope this answer helps. </span>
