Answer:
Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
Answer:
x=8 or x=-2
Step-by-step explanation:
x²-16=6x
x²-6x-16=0
x²-8x+2x-16=0
x(x-8)+2(x-8)=0
(x-8)(x+2)=0
either,. or.
x-8=0 x+2=0
x=8 x=-2
Answer: x = 35
Step-by-step explanation:
since its a 90 degree angle the equation is equal to 90
2x + 20(-20) = 90(-20)
2x/2 = 70/2
x = 35
hope this helps :))
