Answer: 3
Step-by-step explanation:
f(x)= -x + 4
Therefore f(-1)= -(-1)+4= 1+4= 5
h(x)= (3/2)x - 1
Therefore h(2)= (3/2)(2) -1= 3-1= 2
f(-1) - h(2)= 5 - 2= 3

Which of the following shapes is a convex nonagon?
OA)
OB)
OC)
OD)
Answers
It is asking for a convex nonagon, not a convex polygon. So in this case we are looking for a shape with 9 straight lines and 9 angles. Which means we can cross A out.
Now we need to look at which nonagon is a convex nonagon which means that we are looking for the shape having only interior angles measuring less than 180°. So this means that B and D can be crossed out.
Thus, the answer is C.

In systems by substitution what is y=x+8 and x+y=2
Answers
Answer:
x = -3
Step-by-step explanation:
y = x + 8 and x + y = 2
Using substitution, we know that y = x + 8, so:
x + y = 2
x + (x + 8) = 2
2x + 8 = 2
2x = -6
x = -3
Then we solve for y:
x + y = 2
-3 + y = 2
y = 2 + 3
y = 5

3. Find the height of rectangle with area (2x^2-9x+9) ft^2 and width (2x-3) ft
Answers
Answer:
The height of the area is (x - 3) ft.
Step-by-step explanation:
You can do this a few ways. You could use long division to divide the area by the width, or you could just factor the area, which is guaranteed to have the width as a factor, leaving you with the height.
Let's go with factoring, as that's probably what this question is intended as:
[tex]= \frac{2x^2 - 9x + 9}{2x - 3} \\\\= \frac{2x^2 - 6x - 3x + 9}{2x - 3} \\\\= \frac{2x(x - 3) - 3(x - 3)}{2x - 3} \\\\= \frac{(2x - 3)(x - 3)}{2x - 3} \\\\= x - 3[/tex]

Answer:
yes , keiko is correct.
sin^(-1)x = -sin^1
Answer:
Keiko is wrong
Step-by-step explanation:
Keiko is incorrect
When n is positive, 1^n will always be 1
but........ (-1)^n will not always be -1
This is because there are parenthesis around -1
So n is even, then it will be 1 not -1
For example, n = 4
You will do -1 * -1 * -1 * -1 which is 1 not -1
but if n = 3
You will do -1 * -1 * -1 which is -1
Therefore, the second statement is incorrect resulting in Keiko being wrong

Answer:
ur answer should be C. But I'm not really sure..
The table in which y is a linear function of x is; Choice C
Linear functionsAccording to the question;
We are required to identify in what table y is a linear function of x.The slope of a linear function is always constant.
Hence, By observing the table in Choice C;
Slope = (8-6)/(0-(-1)) = (10-8)/(1-0) = 2.
Hence, since slope of the function is constant, the required table is: Choice C.

b) [tex]f^-1(x)[/tex]= ∛(4x-24)
c)2
Step-by-step explanation:
these ones are inverse functions
change the f(x) for y and make x the subject
y= x³/4 +6
(y-6)x 4 = x³
∛(4y-24)= x
then put x back were y is
[tex]f^-1(x)[/tex]= ∛(4x-24)
and to do c just put in 8 where x is
∛(4(8)-24)= 2
solve the equation

(x-11)(x+4)=0
x= 11 or x= -4
Answer:
x = 11 or x = -4
Step-by-step explanation:
x^2 - 7x - 44 = 0
-11 + 4 = -7, -11 × 4 = -44
(x -11)(x + 4) = 0 or (x + 4)(x - 11) = 0 Both are same way: O
x = 11 or x = -4 would be the answer : )
