Answer:
<h2><u>
X= 22.111</u></h2><h2 />
Step-by-step explanation:
<u>Standard form:</u>
9/10x − 199/10 = 0
<u>Factorization:</u>
1/10(9x − 199) = 0
<u>Solutions:</u>
x = 597/27 ≈ 22.111111
Answer:
10 ft.
Step-by-step explanation:
8.8 ÷ 4= 2.2
22÷2.2= 10
It would help if you had a four quadrant graph, but the distance would be (8,11).
Answer: They are not perpendicular because their slopes are not negative reciprocals.
Step-by-step explanation:
For these two lines to be perpendicular, their slopes have to be negative reciprocals.
Slope of FG.
F = (-4, 1)
G = (0, -2)
= (Y₂ - Y₁) / (X₂ - X₁)
= (-2 - 1) / (0 + 4)
= -3/4
Slope of HJ
J = (0 , 4)
H = (-4, -2)
Slope = (Y₂ - Y₁) / (X₂ - X₁)
= (-2 - 4) / (-4 -0)
= 6/4
= 3/2
<em>The slopes of these lines are not negative reciprocals so these lines are not perpendicular. </em>
