Answer:
-21
Step-by-step explanation:
We are told to find f(x) + g(x) for x= -3. Therefore, we must evaluate f(-3) and g(-3), then add them together. 
First, evaluate f(-3). 
f(x)=4x-7
To find f(-3), we need to substitute -3 in for x. 
f(-3)= 4(-3)-7 
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction First, multiply 4 and -3. 
f(-3)= -12-7
Next, subtract 7 from -12 
f(-3)= -19
Next, find g(-3). 
g(x)=2x+4 
To find g(-3), substitute -3 in for x. 
g(-3)= 2(-3)+4 
Solve according to PEMDAS. First, multiply 2 and -3. 
g(-3)= -6+4 
Next, add -6 and 4 
g(-3)= -2 
Now, we can add f(-3) and g(-3) together. 
f(-3) + g(-3) 
f(-3)= -19 
g(-3)= -2 
-19 + -2 
Add 
-21

Answer:
You can decide where to put the first digit because you know 153 doesn't fit into 6 or 61. But you know it can fit into 613. You put it there.

Answer:

With the vertex 
We see that b = -10 and a = 2 and then the vertes wuld be:

And the best option is:
b. (-10,2)
Step-by-step explanation:
For this problem we have the following function:

And if we compare this expression with the general expression for a parabola given by:

With the vertex 
We see that b = -10 and a = 2 and then the vertes wuld be:

And the best option is:
b. (-10,2)
