9(3x - 16) + 15 = 6x - 24
First distribute 9 to 3x and -16.
27x - 144 + 15 = 6x - 24
Combine like terms. (-144 + 15)
27x - 129 = 6x - 24
Get the variable, x, on one side of the equation. You can do this by subtracting 6x from both sides.
21x - 129 = -24
Add 129 to both sides to isolate x.
21x = 105
Divide 21 off of both sides to find the value of x.
x = 5
You can plug x into the equation to check your answer.
9(3 x 5 - 16) + 15 = 6(5) - 24
6 = 6
Answer:
1 x≠0
undefined x=0
Step-by-step explanation:
As long as x is not 0
(4x)^0
=1
Anything to the power of 0 is 1 (except for 0
If x =0 then it is undefined
Answer:
1/2x or x/2
Step-by-step explanation:
You're taking the number you started with and either multiplying it by 1/2 half or dividing it by 2.
Answer:
linear
Step-by-step explanation:
linear equations are ones that go throught the origin if i remember correctly
Answer:
b. {x l -9/7 < x <17/7}
Step-by-step explanation:
l 4 - 7xl -5 < 8
Adding 5 on both sides, we get
l4 - 7xl < 13
Absolute function has two values.
{ 4 - 7x < 13 and (4-7x) > -13}
Now let's solve for x.
-7x < 9 and -7x > -17
x > -9/7 and x < 17/7
Now we have to combine the two inequalities and write the solution
{x l -9/7 < x <17/7}
Answer: b. {x l -9/7 < x <17/7}
Hope this will helpful.
Thank you.
