If f(x) = x2 + 4x + 9. find f(-2)
Answer: f (-2) 5
Your welcome
A function is a relation between two variables where one variable is the set of inputs that gives the other variables as output.
The value of the function at x = -2 is 5.
The domain of the function = 5.
The range of the function = -2.
What is a function?A function is a relation between a set of inputs called domains and it has one output called the range.
Example:
f(x) = x + 2
At x = 2,
f(2) = 2 + 2 = 4
Domain = 2
Range = 4
We have,
f(x) = x² + 4x + 9
We need to find the value of the function at x = -2.
Substitute x = -2 in f(x).
f (-2) = (-2)² + 4x(-2) + 9
f (-2) = 4 - 8 + 9
f (-2) = 5
Thus the value of the function at x = -2 is 5.

Pleaseee helppppp 3-6
Step-by-step explanation:
Here is Slope-Intercept Form for a line: y=mx+b
m is the slope
b is the y intercept
The y intercept is basically the point on the y axis where the line touches.
I will do #3 for you.
Let's first look for the y intercept. We can see that the line touches the y axis at -4, so that's it.
Let's put it into our equation, plugging in -4 for b. This is what we have so far: y=mx-4
To complete this equation, we still need to find the slope, m.
To find it, look at the point where the y intercept is, and count how many units you need to go up or down the y axis, and then right or left the x axis to get to another point on the line. The slope is equal to the change in y ÷ the change in x.
So we see that there's another point on (-3, -2), so let's try to get there from the y intercept.
We need to move two units up and 3 to the left.
In terms of y, we went up +2, and in terms of x, we went down -3
So our slope is 2/-3 or -2/3.
Now that we have our slope (m) and y intercept (b), we can plug it into out Slope-Intercept Equation, plugging in -2/3 for m:
y=-2/3x-4.
We don't need to find x or y. This is our answer for 3. Using the same method, you should be able to find the equations for the rest of the graphs. Good luck.

1. Ed Shapiro works as an office manager. His annual salary is $48,300. What is his monthly salary?
Answer:
The answer is $4025
Step-by-step explanation:
In this problem we are given his annual salary. meaning per year. to find how much he makes in a month, we must divide by how many months there are in a year.
there are 12 months in a year.
so, 48300/12= 4025
hope this helps!
Answer:
$4,025 is his monthly salary.
Step-by-step explanation:
Annual salary means yearly. Since there are 12 months in a year, you would just take his annual (yearly) salary and divide it by 12 in order to get his monthly salary. Thus it would be:
[tex]\frac{48300}{12} =4025[/tex]

Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
d) x = 4/3
Step-by-step explanation:
Given equation,
→ -x + (3/7) = 2x - (25/7)
Now the value of x will be,
→ -x + (3/7) = 2x - (25/7)
→ -x - 2x = -(25/7) - (3/7)
→ -3x = -28/7
→ -3x = -4
→ x = -4/-3
→ [ x = 4/3 ]
Hence, the value of x is 4/3.

Step-by-step explanation:
y < 5x - 4
1 < 5(1) - 4
1 < 1
This is not a true statement. 1 cannot be less than 1 itself so the answer is no.
7x - 4 < 28

Write in Slope Intercept form: x-3y=-15
Answer: Slope = 0.667/2.000 = 0.333
x-intercept = -15/1 = -15.00000
Step-by-step explanation: y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-3y+15 = 0 and calculate its properties
Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000
y-intercept = 15/3 = 5
When y = 0 the value of x is -15/1 Our line therefore "cuts" the x axis at x=-15.00000
x-intercept = -15/1 = -15.00000
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 5.667. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.667 - 5.000 = 0.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.667/2.000 = 0.333
Slope = 0.667/2.000 = 0.333
x-intercept = -15/1 = -15.00000

If AC = 150, AB = 4x+34 and BC = 6x+6, what is the value of x?
Answer:
x = 11
Step-by-step explanation:
If we assume that points A, B, and C are on the same line with B between A and C, then we have ...
AB +BC = AC
(4x +34) +(6x +6) = 150 . . . . use the given expressions
10x +40 = 150 . . . . . . . . . . . . collect terms
10x = 110 . . . . . . . . . . . . . . . . subtract 40; next, divide by 10
x = 11

Find the values of a and b
Answer:
a = 14°
b = 36°
Step-by-step explanation:
4b - 12 + 48 = 180 (supplementary)
Rearrange
4b = 180 - 48 + 12
4b = 144
b = 36°
4a - 8 + 4b - 12 = 180 (supplementary)
sub b = 36 into equation
4a - 8 + 144 - 12 = 180
Rearrange
4a = 180 - 144 + 12 + 8
4a = 56
a = 14°
