There appears to be a typo in your function.
Note: f(x) = 22-8-9 is not a function. The notation f(x) means there should at least one x on the right side. Repost.

What is the equation of this line?
y = 2x
y=12x
y=−2x
y=−12x
The slope of a line is -4, and the y-intercept is -3. What is the equation of the line written in slope-intercept form?
y = -4x - 3
y = 4x - 3
y = -4x + 3
Answer:
y= -4x+-3 = y=-4x-3
The rest are wrong.
Hi there! :)
We are given the slope of the line and its y-intercept.
So, we write the equation in slope-intercept form (y=mx+b)
m is the slope of the line, and b is the y-intercept.
y=mx+b
y=-4x-3
Hence, that's the equation (Option A)
Hope it helps. Use the comment section to clarify your doubts.

Answer:
5. a^3 + b^3 = (a+b)^3 - 3ab(a+b)
Step-by-step explanation:
(a+b)^3
= (a+b) (a+b) (a+b)
={(a+b) (a+b)} (a+b)
={a(a+b) + b(a+b)} (a+b)
=(a^2 + ab + ab + b^2) (a+b)
=(a^2 + b^2 + 2ab) (a+b)
=a^2(a+b) + b^2(a+b) + 2ab(a+b)
=a^3 + a^2b + ab^2 + b^3 + 2a^2b + 2ab^2
=a^3 + b^3 + 3a^2b + 3ab^2
=a^3 + b^3 + 3ab(a+b)
(a+b)^3 = a^3 + b^3 + 3ab(a+b)
(a+b)^3 - 3ab(a+b) = a^3 + b^3
a^3 + b^3 = (a+b)^3 - 3ab(a+b)
Hope this helped!

Step-by-step explanation:
Bentano spends $170 to order 30 pounds of nuts from an online company. The company charges $3.50 per pound for peanuts and $7.50 per pound for almonds. It also charges a flat fee of $13 for shipping and handling.
Which equation can be used to find p, the number of pounds of peanuts Bentano buys?
3.5p+7.5(p−30)−13=1703 point 5 p plus 7 point 5 times open paren p minus 30 close paren minus 13 is equal to 170
3.5p+7.5(30−p)−13=1703 point 5 p plus 7 point 5 times open paren 30 minus p close paren minus 13 is equal to 170
3.5p+7.5(p−30)+13=1703 point 5 p plus 7 point 5 times open paren p minus 30 close paren plus 13 is equal to 170
3.5p+7.5(30−p)+13=170
Given :
Bentano spends $170 to order 30 pounds of nuts from an online company.
The company charges $3.50 per pound for peanuts and $7.50 per pound for almonds. It also charges a flat fee of $13 for shipping and handling.
To Find :
Which equation can be used to find p, the number of pounds of peanuts Bentano buys.
Solution :
Price of peanuts + Price of almonds + Delivery charge = Total amount
3.5p + 7.5( 30 - p ) + 13 = 170

Answer:
this answer is going to a 20 out of 100 percent
the answer is C or D
Answer:
A. Angle C = Angle C'
Step-by-step explanation:
It cannot be B because that would make them congruent by ASA, so it has to be A because C and D are both sides.
If log (100ab^2) is expressed as a function of log b, the result would be:
1). 2 log a + 2 log b
2). 100 log a + 2 log b
3). 2 + log a + 2 log b
4). 2 + 2 log a + 2 log 6
Answer: Choice (3)
2 + log(a) + 2*log(b)
======================================================
Work Shown:
The log rules we'll use are
log(xy) = log(x)+log(y)log(x^y) = y*log(x)log(10) = 1, where the log is base 10So,
c = log(100ab^2)
c = log(100) + log(a) + log(b^2) ......... use log rule 1
c = log(10^2) + log(a) + log(b^2)
c = 2*log(10) + log(a) + 2*log(b) ......... use log rule 2
c = 2*1 + log(a) + 2*log(b) .................... use log rule 3
c = 2 + log(a) + 2*log(b)
Note: The use of rule 3 assumes that all logs shown are in base 10, which is the default assumed base. Rule 3 doesn't work for any general base. The more generalized rule is [tex]\log_b(b) = 1[/tex]. If b = 10, then we get rule 3 above.

There are 48 students in a school play. The ratio of boys to girls is 5:7. How many more girls than boys are in the play? Explain how you found your answer
Answer:
48 students total in the school play
Ratio of boys to girls is 5:7
How many more girls are there than boys in the play?
Let's let "5x" represent the number of boys in the school play and "7x" represent the number of girls in the school play.
5x = boys
7x = girls
If we know that the total number of students in the play equals 48, then that must me that both the number of boys and girls combined must equal 48:
5x + 7x = 48
12x = 48
x = 4
Now, take your x-value and plug it into both the boys' and girls' values to figure out how many boys and girls there are in the play:
5x = 5 (4) = 20 boys
7x = 7 (4) = 28 girls
To find out how many more girls there are than boys in the play, just subtract the number of girls minus the number of boys:
# girls - # boys = 28 - 20 = 8
This means that there are 8 more girls than boys in the school play.

In 2003, the average attendance per game for a football team was about (1 × 104) + (9 × 103) + (9 × 102). What is this number in standard form?
show work
Answer:
1.99 * 10^4
Step-by-step explanation:
Here, we want to write the addition in standard form
= (1 * 10^4) + (9 * 10^3) + (9 * 10^2)
= 10,000 + 9000 + 900
= 19,900
so the number in standard form is;
1.99 * 10^4
(x,3) and (7,-5) given m= -8/7
Answer:
(0, 3)Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
[tex]m[/tex] - slope
[tex]b[/tex] - y-intercept
Given
[tex]m=-\dfrac{8}{7}[/tex]
and point [tex](7;\ -5)[/tex]
Substitute the value of the slope and the coordinates of the point ot the equation of a line:
[tex]-5=-\dfrac{8}{7\!\!\!\!\diagup}\cdot7\!\!\!\!\diagup+b[/tex] cancel 7
[tex]-5=-8+b[/tex] add 8 to both sides
[tex]-5+8=-8+8+b[/tex]
[tex]3=b\to b=3[/tex]
Therefore we have the equation of the line:
[tex]y=-\dfrac{8}{7}x+3[/tex]
Substitute (x, 3) to the equation:
[tex]3=-\dfrac{8}{7}x+3[/tex] subtract 3 from both sides
[tex]3-3=-\dfrac{8}{7}x+3-3[/tex]
[tex]0=-\dfrac{8}{7}x[/tex] divide both sides by (-8/7)
[tex]0=x\to x=0[/tex]

What is the equation of the line perpendicular to y=-1/5x -2 and contains the point (2, -10)?
Answer:
y= 5x-20
Step-by-step explanation:
I didn't understand if I had to find the perpendicular line or parallel haha.
You’re welcome :)
Answer:
y = 5x -20
Step-by-step explanation:
for the line to be perpendicular it must have the inverse slope
therefore m = 5
no substitute the point (2, -10) in for (x, y) respectively to find the y intercept
-10 = 5(2) + b
-10 = 10 + b
b = -20
the equation will be y = 5x -20
