Answer:
20
Step-by-step explanation:
Assuming that the equation is x³ = 64, that can be solved by putting cube root on both sides like so: ∛(x³) = ∛64, which simplifies to <em>x = 4</em>.
Plugging that into our expression gives us <em>4² + 4</em>, which is 20.

Answer: y = -1/4x - 4
Step-by-step explanation:
y = (-1/4)x + 2 (This is the first linear function.)
(4,3) has slope of (-1/4)x or (1/-4)x
4(y2) - 4(y1= the new y -1(x2) -3(x1) = new x which leads to (0,-4) so y-intercept = -4
so all in all, y = (-1/4)x -4 is the answer
Hopefully, you're able to understand this. It's difficult to explain through typed words rather than visually and through a written example.
<span>To calculate the change in CPI we need to do a % change formula. (New - Old) / (Old) = n. (121 - 110) / 110 = .10. This is equal to a 10% change in CPI.
To confirm the answer, do, (Old) * (1+n) = New CPI. 110*(1+.10) = 121. It equals so it is right!</span>
Simple, convert it to a decimal, first
move the decimal two places to the left
45%

0.45.
Then you change it into a fraction
45/100.
But, you can simplify it even more by dividing the numerator and denominator by 5.
45/5=9
and
100/5=20
Thus, it would be simplified, 9/20.
