Answer: x=1
Step-by-step explanation:
4 (-x+4）=12
（-4x+16）=12
-4x+16-16 =12-16
-4x/-4 =-4/-4
x=1

Answer:
1509
Step-by-step explanation:
Answer:
C = 37.7 inches
Step-by-step explanation:
You are looking for the circumference.
Formula for the circumference-> C=2πr
variables:
c = circumference
r = radius
You have the diameter, which is 12 inches. Radius is half of the diameter. which means r is half of 12 (aka 6).
put the radius where the variable is in the formula.
C=2π(6)
you now have enough information to solve for circumference.
C = 2 * π * 6
C = 37.7
4 - 5x = 2x + 25
4 = 7x + 25
-21 = 7x
-3 = x
4 - 5x + 2x + 25 = ac
4 - 5(-3) + 2(-3) + 25 = ac
4 - (-15) + (-6) + 25 = ac
19 + (-6) + 25 = ac
38 = ac
Answer:
both are -10
Step-by-step explanation:
#1
x1 y1 x2 y2
1.5 180 6 135
(Y2-Y1) (135)-(180)= -45 ΔY -45
(X2-X1) (6)-(1.5)= 4.5 ΔX 4.5
slope= -10
B= 195
Y =-10X +195
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#2
x1 y1 x2 y2
1 175 8 105
(Y2-Y1) (105)-(175)= -70 ΔY -70
(X2-X1) (8)-(1)= 7 ΔX 7
slope= -10
B= 185
Y =-10X +185
