Answer:
x = -19
Step-by-step explanation:
-3= 12x-5(2x-7)
Distribute
-3= 12x-10x+35
Combine like terms
-3 = 2x +35
Subtract 35 from each side
-3-35 = 2x+35-35
-38 = 2x
Divide each side by 2
-38/2 = 2x/2
-19 =x
Should be D. (5^2)^2= 5^4 (you multiply them) and 5^4+5^4=5^8
Answer:
Option A
Step-by-step explanation:
If the speed of a car in miles per hour (m) is proportional to the speed in kilometers per hour (k),
m ∝ k
m = ck
Here, c = Proportionality constant
Therefore, c =
should be constant for each value given in the table.
For m = 11 and k = 17.699,
c = 
c = 0.6215
For m = 26 and k = 41.834,
c = 
c = 0.6215
For m = 34 and k = 54.706,
c = 
c = 0.6215
Therefore, c is constant for each value of m and k.
Option A will be the correct option.
