To solve this problem we want to let X equal the amount of points that team A scored. Now we want to express the amount of points that team B scored in terms of X. If team A scored 7 more points than team B then team B scored X-7 points. We know that together they scored 163 points so we can set up this equation: x + x - 7 = 163 2x - 7 = 163 2x = 155 X = 78 Team A scored 78 points
Answer:
y-24=m(x--4)
Step-by-step explanation:
point slope form:
y-y₁=m(x-x₁)
1) find the slope or "m" first:
slope formula: (y2-y1)/(x2-x1)
(-53-24)/7+4
-77/11=-7
slope=-7
so
y-y₁=-7(x-x₁)
y1=24
x1=-4
y-24=m(x--4)

Answer:
She can buy six bulbs of garlic
Step-by-step explanation:
Well you know that each bulb of garlic is 2 dollars. You also know that Stephanie has 12 dollars. In order to solve this you need to take the amount of money Stephanie has and divide it by the price per bulb in order to find out how many bulbs she can buy.
12/2 = 6
She can buy 6 bulbs of garlic
This is relatively easy because that 25 is a perfect square, whose (square) roots are 5 and -5. x^2-10x+25 = (x - 5)(x - 5). Note how (-5)(-5) = +25, and how -5x - 5x = -10x.
The roots are { (x-5), (x-5) }.
