If two parallel lines are cut by a transversal - alternate interior angles are always congruent.
However this doesn’t mean always in this case. So sometimes!
(x+4)(x-3)=30
x^2 +x -12 =30
x^2 +x =42
x^2 +x -42 =0
(i solved it by factorising: _x^2 × -42)
x^2 -6x +7x -42 =0
x(x-6) +7(x-6) 0
(x-6)(x+7)=0
x=6; x=-7
since it's a length, x can't be a negative number, so it must be 6
Answer:
I believe its C , i took this class
Step-by-step explanation:
Answer:
slope = 2, vertical intercept = 10
Step-by-step explanation:
The intercept, also called the y-intercept, is where the line crosses the y-axis
The vertical line (y-int) is crossed at 10, so vertical intercept = 10
Slope equals rise over run:
The line goes up 10 and moves right 5
10/5 = 2
This line has a positive 2 slope
