Answer:
Angle B is 54º.
Step-by-step explanation:
First, find <em>x</em>. Since angle A and angle B are supplementary angles, they add up to 180º.
(7<em>x</em> + 7)º + (4<em>x</em> - 14)º = 180º.
11<em>x</em> - 7 = 180
11x = 187
<em>x</em> = 17.
Now, substitute 17 for <em>x</em> in angle B's equation, (4<em>x</em> - 14).
4(17) - 14
= 68 - 14
= 54º
Answer:
2 solutions:
x=5 and y=7
x=-1 and y=-5
Step-by-step explanation:
y=2x-3
y=x^2-2x-8
y=y so:
2x-3=x^2-2x-8
simplifying to:
x^2-4x-5=0
factoring to:
(x-5)(x+1)=0
x=5 or x=-1
if x=5 then y=2(5)-3=7
if x=-1 then y=2(-1)-3=-5
Answer:
idk
Step-by-step explanation:
(5,38).
38=8(5)-2 is 38=40-2 and that's 38=38.
38=9(5)-7 is 38=45-7 and that's 38=38.
