Step-by-step explanation:5/3 x 3/1= 15/3= 5
Is there a picture that I can use to view where the angle of angle 7 is at?
20, you just need to substitute the x value in the equation
(-2)2-7(-2)+10=
=20
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
