Hey there! :)
Answer:
x = -6.
Step-by-step explanation:
Given:
![\sqrt[3]{5x-4} = \sqrt[3]{7x + 8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x-4%7D%20%3D%20%5Csqrt%5B3%5D%7B7x%20%2B%208%7D)
Cube both sides:
5x - 4 = 7x + 8
Subtract 5x from both sides:
-4 = 2x + 8
Subtract 8 from both sides:
-12 = 2x
x = -6.
Answer:
X=10, x=4
Step-by-step explanation:
first, divide 14 by 2, and square it; giving you
x^2-14x+(7)^2=-40
Because 7^2 is 49, you have to add 49 to the other side; giving you
x^2-14x+(7)^2=9
Then factor the left side; giving you (x-7)^2=9
Take the square root of both sides, giving you
(x-7)^2= plus or minus 3
Then solve to get two solutions, 10 and 4
Move the decimal point to the right (add a zero), therefore, 825,740
Answer:
Domain: All numbers greater than or equal to 0. By definition, the domain of a graph, is the possible x values.
Range: All real numbers. By definition, the range is all possible x values.
Not a function. A function has y value for every x value.
