Answer:
6) 20
7) I think is 2.5 (im not sure)
8) 7
Step-by-step explanation:
6) (5x+9)+(3x+11)=180
8x+20=180
-20 -20
8x=160
Divide 8 on each side
x=20
7) (17x+1)=(20x-14)
17x+15 =20x
+17 +17
15 = 37x
divide 15 on each side
X=2.5
8) (3x+3)+(10-4)=90
(3x)+(10x-1)
13x-`1=90
+1 +1
13x=91
Divide 13 on each side
x=7

Answer:
y = 6x - 20
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6, thus
y = 6x + c ← is the partial equation
To find c substitute (4, 4) into the partial equation
4 = 24 + c ⇒ c = 4 - 24 = - 20
y = 6x - 20 ← equation of line
We need the figure to answer that.
