Answer:
Step-by-step explanation:
given that both angles are the same, it is an equilateral right triangle.
we can use Pythagorean's theorem
For number 22:
7y=8x-14 ; y=6
Plugging in y, we get:
7*6 = 8x - 14
42 = 8x-14
56 = 8x
x = 7
Comparing answers, x is, indeed 7.
We can use slope , point formula
y-y1=m(x-x1)
m is a slope=(y2-y1)/(x2-x1)=(-10-(-7))/(2-1)=-3
for example, we take the point (1, -7)
y-(-7)=-3(x-1)
y+7=-3x+3
y=-3x-4
Answer:
26.37
Step-by-step explanation:
Apparently, we're to substitute 9 for 4 and recompute:
26.37 = (2.93)9
____
This assumes that the 4 in the expression is the number of boxes, and the (2.93) in the expression is the price per box. The product of those numbers is 11.72, apparently the total cost of 4 boxes of nails.
