Answer: y-2=1/4(x-1)
Step-by-step explanation:
The formula for point-slope is y-y₁=m(x-x₁). Since we are given the slope m, we can fill that in. We are also given the point (x₁,y₁). We can also fill that in.
y-2=1/4(x-1)
The answer is "3600 ft²".
Left triangle area=(1/2) x (30 ft) x (72 ft) = 1080 ft²
Middle walkway area=(20 ft) x (72 ft) = 1440 ft²
Right triangle area
=same as left triangle area, 1080 ft²
Total area1080 ft²+1440 ft²+1080 ft² = 3600 ft²
Now you can also check that;
Parallelogram area = base x height = (50 ft) x (72 ft) = 3600 ft²
6. 1,750 mg in a week 7. 1.75 g in a week
They have the same volume, so it's not a or d, but the surface area of a is 104, and the surface area of b is 94, so the answer is B.
Hope i helped! i also have this question in k12.<span />
B² - 4ac
= 8² - 4*(-2)*(-9)
= 64 - 72
= -8
