12/15=8/(x-4)
12(x-4)=8(12)
12x-48=96
12x=144
x=12
Answer:
14
Step-by-step explanation:
f'(2) = 2y + 10
f'(2) = 2(2) + 10
= 4 + 10
= 14
Answer:D
Step-by-step explanation:
In order for the polynomial to be a degree of 4, it must have exactly 4 roots. According to the fundamental theorem of algebra: "The number of roots in a function is equivalent to the degree of the function"
These roots do not have to be real numbers, which means they can be imaginary or complex.
In this case, (-11 - √2i), (3 + 4i), and 10. There are three roots, which means that the polynomial can be a third of fourth degree polynomial. It is wrong for Patricia to assume that this is a fourth degree polynomial when only three roots are known.
<h3><u>The degree of the polynomial will at least be three, but could be higher.</u></h3>
Answer:
multiply 4 and 8 to get 32
Step-by-step explanation:
After substituting, the expression is ...
4·8 +9/7
The order of operations tells you to do multiplication and division before addition and subtraction. You do them left-to-right. The multiplication on the left is 4·8, so you do that first. The result is ...
32 + 9/7
Now, you can do the division:
32 + (1 2/7)
And, finally, the addition:
33 2/7
___
Or, you could skip the division and go straight to adding a whole number and a fraction:
(32·7 +9)/7 = (224+9)/7 = 233/7
