Answer:
84x¹²
Step-by-step explanation:
To simplify this expression, we work from left to right:
4x(-3x⁸)(-7x³)
Multiplying the coefficients of the first two, we have 4(-3) = -12. Using the laws of exponents, multiplying powers with the same base means we add the exponents; this gives us x(x⁸) = x¹⁺⁸ = x⁹. This gives us
-12x⁹(-7x³)
Multiplying the coefficients, we have -12(-7) = 84. Using the laws of exponents, for the variable we have x⁹(x³) = x⁹⁺³ = x¹²
This gives us
84x¹²
Answer:
−2<x<5
Step-by-step explanation:
x2−3x=10
x2−3x−10=10−10(Subtract 10 from both sides)
x2−3x−10=0
(x+2)(x−5)=0(Factor left side of equation)
x+2=0 or x−5=0(Set factors equal to 0)
x=−2 or x=5
Check values in the intervals to see if they work.
x<−2(Doesn't work in original inequality)
−2<x<5(Works in original inequality)
x>5(Doesn't work in original inequality)
So, the proper answer for me is −2<x<5.
86÷8=10.75
10.75 would be the answer which lies between 10 and 11
Answer:
Option B
Step-by-step explanation:
Domain of a function is represented by the set input values or x-values
Range of the function is represented by the set of output values or y-values.
From the graph attached,
y-values are varying from y = - 9 to y = 8.
Therefore, range of the function from the given graph will be,
-9 ≤ y ≤ 8
Option B will be the correct option.
