Answer:
Step-by-step explanation:
X-3y=-5x
(-2y)-3y=15(-2y)
-3y=15
y=-5
The answer is 2.
The formula for slop is y2-y1/x2-x1
Using this formula we get 12-4/6-2 or 8/4 which simplifies to 2.
Hope this helps!
Answer:
70 yards.
Step-by-step explanation:
50% is also 1/2, so you put 140/2, and get 70.
To calculate the number of shingles, we first calculate for the total area of the roof of Janice's house. From the figure, we can calculate the area of the two shapes: pyramid and a rectangular prism.
A(pyramid) = lw+l√[(w/2)²+h²]+w√[(l/2)²+h²]
A = 208 m²
A(prism) = 2(wl+hl+hw)
A = 293 m²
Total area = 501 m²
Number of shingles she needs = 501 m² / 2.25 m² =<span> 223</span><span>

1.
The ordered pairs (-2,3) and (5,1) make the inequality true.
2.
The simplified form of the expression is 3y-30.
