Step-by-step explanation:
-28÷4=2
-7=2
= -7-2
= -9 is the correct answer..
Answer:
<em>x = 5/3 </em>or<em> x = -3</em>
Step-by-step explanation:
3x² + 4x - 15 = 0
Factor left side.
(3x - 5)(x + 3) = 0
Set factors equal to 0.
3x - 5 = 0
3x = 5
x = 5/3
x + 3 = 0
x = -3
Answer:
B
Step-by-step explanation:
b and a=40⁰ so if b+c is supplementary they equal 180⁰ together so 180-40= 150⁰
Answer: You can't answer this, but here are some guidelines
Step-by-step explanation:
I would love to answer this question (coming from someone who has already completed algebra keystones) but I need to know what the linear equations are before I can. If the functions are reciprocals of one another (the slope is the opposite and the fraction is switched) it is a perpendicular line which means one solution. If the slope is the same but the intercept is different (using y=mx+b) so if b is different but m is the same they are parallel and there is no solution. If they are the same line (same equation) there is infinite solutions. If this doesn't help I would suggest finding graph paper and trying it out and seeing the intersection points.
The measure of angle B is 97°
