Answer:
7
Step-by-step explanation:
The order of operations tells you to start any evaluation by looking at the innermost set of parentheses first.
Here, that means your first step is to find the value of h(-3). You do that by finding the input (x) value -3 in the table for h(x), and locating the corresponding output, h(x), which is 2.
Now, the problem becomes evaluating g(2).
You do the same thing for that function: locate the input x=2 in the table for g(x) and find the corresponding output: 7.
Now, you know ...
g(h(-3)) = g(2) = 7
4.05 you multiply 2.25 times 1.8
This is a linear equation y = mx, where:
m= slope or reading rate:
x = the number of minutes
y = the number of pages read.
So the equation becomes: y = 4.5.x
How many minutes it will take to read 90 pages (y):
90 = 4.5.x or x = 90/4.5 and x = 20 minutes
So the ordered pair will be (20,90)

$725 ÷ 5 = $145
Answer:
-15
Step-by-step explanation:
so to start you must distribute negative two times negative two equals positive four,
so now your equation looks like this,
2^2 +4+4-3^3
then you need to do the exponents,
2 x 2 = 4
3 x 3 x 3 =27
now it looks like this
4+4+4-27
12 - 27
-15
Hope that helps!
