Answer:
g^-1(x) = (x - 5)/-6
Step-by-step explanation:
g^-1(x) refers to an inverse function. To find any inverse function, we must replace g(x) with x and x with g(x). We can then solve for the new g(x) and that would be the composite function.
g(x) = -6x + 5 ------> Swap x and g(x)
x = -6g(x) + 5 -----> Subtract 5 from both sides
x - 5 = -6g(x) ------> Divide by -6
(x - 5)/-6 = g(x)
Answer: x=7
Step-by-step explanation:
Let's solve your equation step-by-step.
8x+10=12x−18
Step 1: Subtract 12x from both sides.
8x+10−12x=12x−18−12x
−4x+10=−18
Step 2: Subtract 10 from both sides.
−4x+10−10=−18−10
−4x=−28
Step 3: Divide both sides by -4.
-4x/-4 = -28/-4
answer: x=7
The answer is $160. All you have to do is add it up
Answer:
m<D = 20.7
Step-by-step explanation:
Let's remember that all three angles in the interior must be equal to 180 degrees
Second, you're given the measure of tw angles with the thrid missing
Let's solve:
(5x-8)+ (4x-19)+ x = 180 .... x is the third angle which is not given
Now simplify:
5x- 8+ 4x- 19 +x = 180
Combine like terms:
10x -27 = 180
10x = 180+ 27
Now plug in the value of x into each of the angle measures:
5*20.7 - 8= 95. 5
4*20.7 - 19= 63.8
Now let's see how much is the other angle based on our data:
95.5+ 63.8+ x= 180
x= 180- 95.5 -63.8
m<D = 20.7
10x = 207
x= 207/10
x= 20.7
Answer: 0 = 0
Many solutions
Step-by-step explanation:
4x - 3y = 13
8x - 6y = 26
-2(4x - 3y = 13)
-8x + 6y = -26
8x - 6y = 26
You can cross them all out and you’ll get 0 = 0 which also means many solutions
