Since both are equivalent to f(x), 4x-7 must equal 8
4x-7=8
Add 7 to both sides
4x= 15
Divide both sides by 4
x=15/4
Final answer: x=15/4
Answer:
25 feet
Step-by-step explanation:
x^2= 20^2+15^2
x ^2 = 400 + 225
x ^2 = 625
x^2= √625
x= 25
$1.50C + $4A= $5050
C + A = 2200
-4(C + A = 2200)
-4C - 4A = -8800
1.50C+4A = 5050
-----------------------
-2.5C =- 3750
-2.5C/-2.5 =- 3750/-2.5
C = 1500
C + A = 2200
1500 + A =2200
1500 - 1500 + A = 2200 - 1500
A = 700
CHECK
$1.50C + $4A= $5050
$1.50(1500) + $4(700)= $5050
$2250 +$2800 =$5050
$5050 = $5050
C + A = 2200
1500 + 700 =2200
2200 = 2200
