40 represents a total, but then 45% represents a part. First of all, let's find the amount of girls in the club.
45% of 40
= 18 girls
If it was increased to 56%:
56% of 40
= estimated 23, since we can't have two fifths of a person.
23 - 18 = 5 new girls joined.
The equation has 0 solutions.
Answer:
The plane PRS passes through the points P, R and S. So it contains the line RS. Also the plane QRS passes through the points Q, R and S. So it contains the line RS as well. Since both the planes contain the line RS, the line RS must be the intersection of plane PRS and QRS

Answer:
D. 2x + 7
Step-by-step explanation:
Use the point given, (-3, 1), and put it into the point-slope formula.
y - 1 = m(x+3)
The m, or the slope, is still blank. When you want a line parallel to a certain slope, the slope remains the same. Therefore, you plug in 2 for m:
y - 1 = 2(x+3)
y - 1 = 2x + 6
y = 2x + 7
