Step-by-step explanation:
2(2+20)=80
4+40=80 (Distribute)
4+40-40=80-40(Subtract from both sides of the equation)
4=40(Simplify)
4/4=404/4(Divide both sides of the equation by the same term to get x=10)
=10
Answer:
y = -6 * x^3
Step-by-step explanation:
We can model the new function as:
f(x) = ax^3
the function y = x^3 have positive values of y for positive values of x, and negative values of y for negative values of x.
As the negative values of x have positive values of y and vice-versa, the first change is to put a negative sign in front of x^3, so we know that 'a' is negative.
Then, for x=1 we have y = -6, so:
-6 = a*1^3
a = -6
So the equation of the transformed function is:
y = -6 * x^3
Answer:
AB=8 BC=17 AC=9 BD=18
Step-by-step explanation:
Okay, so A is -3 and B is 5, so the distance would be 8, because the difference between -3 and 5 is 8. The same goes for all the rest. The distance on the number line is the difference between the two numbers they represent.
3/4 x n=1......n equals 4/3.
In order for n to equal 1 you have to find a number that will make 3/4 a whole number after you multiply it. Usually in problems like these the answer is usually the fraction but flipped around. So 3/4 and 4/3....when you multiply the numerators you get 12 and when you multiply the denominator you get 12 so 12/12, which equals 1. hope that makes sense.
