The correct answer is B x=-3 and x= positive 5/2
The missing coordinate r is 11.
Solution:
Given points are (–15, 1) and (–7, r).

Slope (m) = 
<u>To find the missing coordinate r:</u>
Slope formula:

Substitute the given values in the formula.



Do cross multiplication.

40 = 4r – 4
Add 4 on both side of the equation.
44 = 4r
Divide by 4 on both side of the equation.
11 = r
⇒ r = 11
Hence the missing coordinate r is 11.
Answer: 7.3x + 5
Step-by-step explanation:
For us to solve the question, we have to solve 5.2x+8+2.1x-3 and the answer gotten will allow us know the equivalent expression.
= 5.2x+8+2.1x-3
= 5.2x + 2.1x + 8 - 3
= 7.3x + 5
Therefore, the correct answer is 7.3x + 5
For 1. (Monday), it is rational. For 2. It is C. For 3. It is -15/24 (I am assuming, it isn’t clear), -2 2/5 (Assuming) and -0.95. 4. Is less than 1. The decimal it is 0.625. 5. 11/5 is greater than 1. The decimal is 2.2. For 6. It is equal to 1. 1 is 1.000 or 1. In decimal form. For 7. It is less than 1. The decimal is 0.571. It is only for Monday. I hope this helps!
