28: y=3x-2
the coefficient of x in an equation, as long as y's coefficient is 1, is the slope. To get to the y intercept you plug 0 for x in the equation. You were correct in that part.
29: y=-3x+5
this time the intercept stays the same. You have to change the coefficient of x to -3 for the slope to be -3.
Answer:
n = 6
Step-by-step explanation:
17n + 4n - 4 =122
combine like terms 17n & 4n
21n - 4 = 122
21n - 4 + 4 = 122 + 4
21n = 126
21n / 21 = 126 / 21
n = 6
3.12 dollars you have to divide 2.35 by 3 and then multily it by 4 to get 3.12 cents
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
