Answer:
C
Step-by-step explanation:
The temperature must not be greater than 15 which means 15 is the maximum. It's not saying it can't reach 15, it's saying it can't go past it.
So it wouldn't be t < 15. It would be t is less than or equal to 15
Answer:
4 boys
Step-by-step explanation:

3 × y = 1 × 12
3y = 12
3y ÷ 3 = 12 ÷ 3
y = 4
Answer:
t
Step-by-step explanation:
Line
is the transversal.
By evaluating the quadratic function, we will see that the differential quotient is:

<h3>
How to get (f(2 + h) - f(2))/h?</h3>
Here we have the quadratic function:

Evaluating the quadratic equation we get:

So we need to replace the x-variable by "2 + h" and "2" respectively.
Replacing the function in the differential quotient:

If we simplify that last fraction, we get:

The third option is the correct one, the differential quotient is equal to 8 + 4.

Answer:
E
Step-by-step explanation:
A linear equation is in the form of:
, where m is the slope and b is the y-intercept.
m is the slope and it's given, which is -6
b is the y-intercept and it's given, which is 9
When we plug in to the form we get:
