Answer:
<em>% is the decrease.</em>
<em />
Step-by-step explanation:
<em>To figure out the percentage decrease, you would first subtract the two numbers. </em>
<em />
<em />
<em />
<em />
<em>Next, you would divide that number by the total.</em>

<em /><em>% </em><em>would be the decrease percentage. </em>
When a function is shifted to the right by 1 unit it is moved towards the negative side so we would be adding -1 to the value of x. The function f(x) would be f(x-1). To determine the resulting function, we substitute to the parent function (x-1) to x. We do as follows:
<span>f (x) = x^3 + 2x^2 − 3x − 5
</span>f (x-1) = (x-1)^3 + 2(x-1)^2 − 3(x-1) − 5
f (x-1) = x^3 - 3x^2 + 3x - 1 + 2(x^2 - 2x + 1) - 3x + 3 - 5
f (x-1) = x^3 - 3x^2 + 2x^2 + 3x - 4x - 3x - 1 + 2 + 3 - 5
f (x-1) = <span>x^3 - x^2 - 4x - 1
Therefore, the correct answer is the last option.</span>
To solve for x, you need to isolate/get x by itself in the equation:
Square ² both sides to get rid of the square root √
x - 2 = 0 Add 2 on both sides
x - 2 + 2 = 0 + 2
x = 2
Answer:
x=-4
Step-by-step explanation:
-2x+18-1x+4=34
step 1 combine like terms
-2x+-1x=-3x
18+4=22
-3x+22=34
step 2 subtract each side by 22
-3x=12
step 3 divide each side by -3
x=-4
hope this helps (:
