F(x)=3 is a horizontal line to the x-axis, which means that the y- intercept is (0,3) and there is no x-intercept.
Y- intercept is (0,3)
Answer:
1 Factor out the common term 22.
2(2x+y)=102(2x+y)=10
2 Divide both sides by 22.
2x+y=\frac{10}{2}2x+y=

to 55.
2x+y=52x+y=5
4 Subtract yy from both sides.
2x=5-y2x=5−y
5 Divide both sides by 22.
x=\frac{5-y}{2}x=

and 
.
Step-by-step explanation:
The given radical expression is
![\sqrt[3]{16x^5y^3z}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B16x%5E5y%5E3z%7D)
We have to simplify the above expression.
The above expression can be written as
![\sqrt[3]{(2\times 8)(x^{3+2})y^3z}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%282%5Ctimes%208%29%28x%5E%7B3%2B2%7D%29y%5E3z%7D)

The answer is 243 I believe
Step-by-step explanation:
Multiply 27 times 6, once you get the product of that, multimply that by 3. Once you have done all of that multiply that by 1/2 or 0.5
Answer:
21. d. 39
22. c. 20; 7
Step-by-step explanation:
21. This is straightforward evaluation of the function. Put the numbers 8 and -5 where x is in the function definition and do the arithmetic. Then find the difference of the results.
f(8) = 3·8 -2 = 22
f(-5) = 3·(-5) -2 = -17
f(8) - f(-5) = 22 - (-17) = 22 +17 = 39
__
22. The first part is similar to 21—evaluate the function for x=2.
f(2) = 24 -2·2 = 24 -4
f(2) = 20
Note that this result is sufficient to allow you to choose the correct answer.
However, we can also do the second part. Find x for f(x) = 10
f(x) = 24 -2x
10 = 24 - 2x . . . . . . substitute 10 for f(x)
-14 = -2x . . . . . . . . . subtract 24 from both sides
7 = x . . . . . . . . . . . . . divide both sides by -2
