Answer:
f(-9) = -263
Step-by-step explanation:
f(-9) = -3(-9)^2 - 20
= -3(81) - 20
= -243 - 20
= -263
Please answer for last question
Step-by-step explanation:
since you know already that it is a linear equation with a constant change rate (slope), you don't know the equation itself yet ?
you found the change rate (slope).
it is x goes up by 2, and y goes down by 6.
the slope is the ratio y/x representing the y and x changes, and it is always the factor of x.
"down" or "left" means "-","up" or "right" means "+".
the slope here is therefore
-6/2 = -3/1 = -3
so, we know the line function looks like
y = -3x + b
to get b we use one of the x y pairs like (1. 4)
4 = -3×1 + b
7 = b
and the full line function is
y = -3x + 7

Answer:
First part = 2.
Time to land = 6 seconds.
Step-by-step explanation:
The object is at h = 0 when it land so
-5x^2 + 20x + 60 = 0
-5(x^2 - 4x) = -60
-5[(x - 2)^2 - 4] = -60
(x - 2)^2 - 4 = -60/-5 = 12
(x - 2)^2 = 16.
Solving the above:
Take the square root of both sides:
x - 2 = 4
x = 2 + 4
x = 6 seconds
What is the answer? Thank you so much

Kerri sold her purse for $351. She had originally purchased it for $316. Calculate her profit or loss percentage.
Answer:
$35 profit
Step-by-step explanation:
351-316=35
Answer:
$35
Step-by-step explanation:
she bought it for $316 and sold it for more than she bought it for so we know that she made money.
so all we have to do is subtract 351 from 316
Can someone help me with this?

Complete the following products.
1. (x - y) (x² + xy + y²)
= (__) x² + (__) xy + (__) y²
= __ - x²y + x²y - xy² + __ - y³
= x³ - __
1. (x - y) (x² + xy + y²)
= (X )x² + (X ) xy + (y) y²
= ( x^3)- x²y + x²y - xy² +(xy^2) - y³
= x³ -y^3
Here is your answer !

8/13×2/6 in its simplest form
Answer:
[tex]\frac{9}{39}[/tex]
Step-by-step explanation:
Multiply the two denominators together and the two numerators:
[tex]\frac{8}{13} * \frac{2}{6} = \frac{8 * 2}{13 * 6}[/tex]
[tex]= \frac{16}{78}[/tex]
Divide both numbers by two to simplify:
[tex]\frac{18 / 2}{78 / 2} = \frac{9}{39}[/tex]
So the simplest form is:
[tex]\frac{9}{39}[/tex]
Hope this helps!
Mental Math Using the slope formula, find the slope of the line through the points and . Use pencil and paper. Explain how you can use mental math to find the slope of the line. slope is 0,0 and 2,4
Answer:Slope is 2, assuming "0,0 and 2,4" is meant to read (0,0) and (2,4) for the 2 points.
Step-by-step explanation:
The slope is the Rise (change in y) over the Run (change in x). I can see the change in y is 4 (it goes from 0 to 4) and the change in x for this interval is 2 (goes from 0 to 2, or 2-0 = 2). Rise (4) over Run (2) is slope 2. 4/2 = 2 slope.
Sally brought the pizza shown above for lunch which was cut into 10 equal slides what percentage of the pizza did tell they eat if she had four slices
Answer:
25%
Step-by-step explanation:
Answer:
Sally ate 40% of the pizza and there was 60% of the pizza leftover.
Step-by-step explanation:
A percentage is a rate, number, or amount in each hundred.
There were 10 slices of pizza, she ate 4.
4/10 = 40/100 multiplied by 10, which would let us find the percentage.
Therefore, Sally ate 40% of the pizza and left 60% back.

Math need help one question
Answer: Multiply the second equation by -2
Explanation:
The elimination method requires you to set one variable in an equation to be the opposite of that variable in another equation. As such, due to the presence of 2x in the top equation, you need -2x in the bottom. Then, simply add the equations to get the answer.
Hope it helps :)
If Rosa walks 3 miles in 40 minutes, then Rosa will walk how far in 70 minutes if she walks at the same
speed the whole time? If necessary, round your answer to the nearest tenth of a mile.
miles.
Answer:
5.25 miles.
Step-by-step explanation:
1) Rosa spends 10 minutes in 3/4=0.75 miles, then
2) Rosa can spend 70 in 0.75*7=5.25 miles.
Answer:
5.3 miles
Step-by-step explanation:
3miles/40min =x miles/70min
cross multiply the fractions
3*70 = 40*x
210=40x
divide by 40 on both sides
210/40 = 5.25
2. Find the perimeter of a rectangle of
Length 13m with an area of 65m
Answer:
Perimeter = 36m
Step-by-step explanation:
Area = l x w
65m = 13m x w
5m = w
Perimeter = 2(l + w)
Perimeter = 2(13m + 5m)
Perimeter = 36m
Answer:
36m
Step-by-step explanation:
The equation for the area of a rectangle is A = w*l, where w = width and l = length
Since we already have the area and the width, we can plug those values into the equation to find the width (w)
A = w*l
65 = w*13
we can divide both sides by 13 to isolate the w variable, and we get that
w = 5
The equation for the perimeter of a rectangle is
P = 2(l +w)
P = 2(13 +5)
P =36
The perimeter is 36m

The polynomial of degree 5, P(2), has leading coefficient 1, has roots of multiplicity 2 at x = 4 and
x = 0, and a root of multiplicity 1 at 3 3.
Find a possible formula for P(x).
P(x)
Answer:
[tex]P(x)=x^{5} +x^{4} -5x^{3} +3x^{2}[/tex]
Step-by-step explanation:
Each root corresponds to a linear factor, so we can write:
[tex]P(x)=x^{2} (x-1)^{2} (x+3)\\=x^{2} (x^{2} -2x+1(x+3)\\\\=x^{5} +x^{4} -5x^{3} +3x^{2}[/tex]
Any polynomial with these zeros and at least these multiplicities will be a multiple (scalar or polynomial) of this [tex]P(x)[/tex]
Footnote
Strictly speaking, a value of [tex]x[/tex] that results in [tex]P(x)=0[/tex] is called a root of
[tex]P(x)=0[/tex] or a zero of [tex]P(x)[/tex] . So the question should really have spoken about the zeros of [tex]P(x)[/tex] or about the roots of [tex]P(x)=0[/tex]

How long would it take eight lumberjacks to chop down eight trees at the same rate?
Answer:
4 hours
Step-by-step explanation:
It take them 1.5 h ÷ 0.5 h to chop down 1 tree, so it would take 0.5 h × 8 = 4 hours to chop down 8 trees
