Answer:
the anser would be 11
Step-by-step explanation:
Step-by-step explanation:
the line passes through (0,-2) and perpendicular to the graph of y=5x+7.
solution :
the slope = -1/5
the equation :
y+2 = -1/5 (x-0)
y = -1/5x - 2
The formula of the area of the circle is
Area = pi * (d/2)^2
So using the formula,
Area = 3.14 * (30/2)^2
Area = 3.14 * 15^2
Area = 706.5 ft^2
So the area of the hockey rink is 706.5 ft^2
<span>y = 3x - 4
</span><span>(4,2); when x = 4; y = 3(4) - 4 = 9 ........FALSE
(1, -1)</span>; when x = 1; y = 3(1) - 4 = -1 ........TRUE<span>
(-1, -7)</span>; when x = -1; y = 3(-1) - 4 = -7 ........TRUE<span>
(2, 2)</span>; when x = 2; y = 3(2) - 4 = 2 ........TRUE
answer
(1, -1)
(-1, -7)
(2, 2)
