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:

4) 20² =400
5) 10³ =1000
Step-by-step explanation:
using your calculator to (square = number times itself) or (cube = number times itself times itself again)
Answer:
487=3x-17
487+17=3x-17+17
3x=53
3x/3=53/3
x=168

Answer:
Function 2 has a greater initial valueStep-by-step explanation:An initial value of a function, aka y-intercept, is obtained by using x=0 and evaluating the function at that point. Evaluating the two functions given:Function1: Function2 has value 3 for x=0So, Function 2 has a greater initial valueFunction 2 has a greater initial valueStep-by-step explanation:An initial value of a function, aka y-intercept, is obtained by using x=0 and evaluating the function at that point.
