C^2-64 is a square roots factoring one. you take the square root of c^2 which is c and then the square root of 64 which is 8 or -8 so the answer is (c-8)(c+8). and it is a special product
X+a=b
you want to isolate x so subtract a from both sides
x=b-a
Answer:
x = 2/3
Step-by-step explanation:
combine -3 and 1. We get -2 there, and now have:
-2 + 10x = x + 4.
Combining the x terms, we get 9x = 6, so that x = 6/9, or x = 2/3
15kg=33 lbs
48.4 lbs/2.2 lbs. =22 kg
1 kg = 2.2 lbs so when you need to make a conversion wityh kilograms and pounds write that out then put how ever many pound you need to get to under the 2.2 lbs and cross multiply same with the kilograms.
Answer:
y = 9x/2 + 17/2
Step-by-step explanation:
Use the slope formula: 
to find the slope of the line.
(4 - (-5)) / (-1 - (-3)) = (4 + 5) / (-1 + 3) = 9 / 2
y = mx + b
m is for slope, b = y-intercept
y = 9x/2 + b
Plug in one pair of the known values:
(-1,4)
4 = 9(-1)/2 + b
b = 4 + 9/2 = (8+9)/2 = 17/2
y = 9x/2 + 17/2
If you want to check if the equation is right, you can plug in the other pair of values into the equation:
(-3,-5), y = 9x/2 + 17/2
-5 = -3*9/2 + 17/2
-5 = -27/2 + 17/2
-5 = -10/2
-5 = -5
