[tex]f(x)=x+7\\g(x)=x-4\\f(x)*g(x)=(x+7)(x-4)\\f(x)*g(x)=x^2+3x-28[/tex]
So it's x^2+3x-28
The value of the function f (x) is 15/2 when x = -5 and is -73/2 when x = 3. What is the equation of the function?
Answer:
y = -5.5x - 20
Step-by-step explanation:
There are many functions that cross those points.
Assuming you're looking at a straight line.
y = mx + b
15/2 = -5m + b --> 7.5 = -5m + b
-73/2 = 3m + b --> -36.5 = 3m + b
Subtract the first from the second.
-44 = 8m
m = -5.5
Plugging back into the first equation, we get b = -20
Answer:
f(x) = −11/2x − 20

Which ordered pairs are solutions to the inequality y−3x<−4? Select each correct answer.
Answer:
Okay so what you need to understand first is that this is a line right?
So, ask yourself if you know how to graph this line.
If you do graph it, and because this line has a < less than sign it means you shade down but it also means that any point directly on the line won't be a solution because the line is dashed!
There can be many solutions to this line, but only in the solution area/shaded region. This in on the lower right side of the diagonal line that is crossing from almost 2 x-axis to -4 y- axis on the line!
If you would've shown me the list of ordered pairs I would've been able to select the correct ones.
Answer:

Find the percent of increase from 2005 to 2010.
Answer:
0.249%
Step-by-step explanation:
Difference: 2010 - 2005 = 5
Increase = Difference / Starting point = 5 ÷ 2005 = 0.00249 or 0.249%
If f(x) = 2x – 4 and g(x) = x 2 – 4x, find each value.
Answer:
Step-by-step explanation:
First, solve for each function separately:
F(5)=52+4(5)F(5)=25+20⇒F(5)=45
G(6)=2(6)+2G(6)=12+2⇒G(6)=1
Now, let's add our solutions together:
F(5)+G(6)=45+14=59
Solve the equation. If necessary
[tex] \frac{3}{4}x + 2x = - \frac{1}{4} + \frac{1}{2}x + 5[/tex]
Answer:
Exact form: x=19/9
decimal form: x=2.1r
Mixed number form: x=2 1/9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = [tex]\frac{19}{9}[/tex]
Step-by-step explanation:
First, make all the different parts into fractions with a common denominator, so that you can add and subtract them easily. In this case, the common denominator is four.
Doing this, you get [tex]\frac{3}{4} x + \frac{8}{4} x = -\frac{1}{4} + \frac{2}{4} x + \frac{20}{4}[/tex]
Isolate all the variables to get [tex]\frac{3}{4} x + \frac{8}{4} x - \frac{2}{4} x = -\frac{1}{4} +\frac{20}{4}[/tex]
Then, combine like terms [tex]\frac{9}{4} x = \frac{19}{4}[/tex]
Multiply both sides by 4 to get 9x=19
Divide both sides by 9, and you get [tex]x= \frac{19}{9}[/tex]
Hope this helps! :)

Which situation presents an example of a proportional function?
A. A game rental company charges $3.50 per game.
B. An art studio charges a registration fee of $25, plus a monthly fee of $40.
C. The temperature in the morning was 56 degrees and it increased by 2 degrees every hour.
D. A pizza parlor charges $5 for a small cheese pizza, plus $2 for each additional topping.
Answer:
The answer is A
Step-by-step explanation:
A proportional function is a function where the output = constant x input
Let's make each of these situations into an equation
A) y = 3.5x
B) y = 40x + 25
C) y = 2x + 56
D) y = 2x + 5
because A is the only one that follows the output = constant x input rule it is the example of a proportional function
sherry has 1/4 as many crayons as marie . marie has 32 crayons how many crayons does sherry have
Answer:
8 crayons

6. -18x - 2 = 6
7. 20x - 4 = -2
8. 2 (4x - 2) = -2
9. -2 (3x+4) = -2
10. - (x + 3) = -10
11. 20x -4 - 2x + 2 = -6
12.) -22x +4 -2x = -6
Step-by-step explanation:
6. -18x = 6+ 2= 8

Find the angle measures. Justify your responses.
Given: a||b, m∠3=63
Find: m∠6,m∠7
Answer:
m∠6 = 117°
m∠7 = 63°
Step-by-step explanation:
It's given that a║b and m∠3 = 63°
Since, ∠3 and ∠6 are the consecutive interior angles,
m∠3 + m∠6 = 180°
63° + m∠6 = 180°
m∠6 = 180° - 63°
= 117°
Since, ∠3 and ∠7 are the corresponding angles,
Therefore, ∠3 ≅ ∠7
m∠7 = m∠3 = 63°
