Step-by-step explanation:
Answer:
x = 3
y = -5
Step-by-step explanation:
It would be very easy to eliminate y by adding the two equations,
4x - 7y = 47
<u>6x + 7y = -17</u>
10x = 30
x = 3 4(3) - 7y = 47
12 - 7y = 47
-7y = 35
y = -5
Check: See if the values work in the second equation
6(3) + 7(-5)
= 18 - 35
= -17 It looks like they work, so we know we have the correct values
Step-by-step explanation:
Angle b + 100 = 180 (angles on the same straight line)

Angle c = Angle b (Vertically opposite angles)
= 80 deg
Answer:
F(5) = 17, F(4) = -19
Step-by-step explanation:
F(5) = 4(5) - 3
F(5) = 20 - 3
F(5) = 17
F(4) = 4(-4) - 3
F(4) = -16 - 3
F(4) = -19
