The first one is correct I think.
15x+40=115
15x means 15 per week solve for x if you want to know how many weeks 40 is what he has only once
Answer:
<h2>Her prediction will be somewhat likely to be close to the actual value.</h2>
Step-by-step explanation:
A correlation coefficient of 0.55 implies a weak positive correlation, because it's close to 0.50. Remember that strong correlations are 1 or -1, positive or negative, and the middle of the interval represents no correlation.
Having said that, 0.55 indicates some correlation, but weak. Therefore, the right answer is C.
<span>parallelogram, opposite sides are equal
</span>so
5x - 8 = 2x + 7
3x = 15
x = 5
hope it helps
Paralell lines have same slopes
y=mx+b
m=slope
given
y=-3x-8
slope is -3
so we just have to have y=-3x+b
