3x^2-11x-20
Drop Down menu is same for both:
2 , 4 , 5 , 10
will award a lot of points
Answer:
2 and 5
Step-by-step explanation:
Use the sum-product pattern
3x^{2}{\color{#c92786}{-11x}}-20
3x^{2}+{\color{#c92786}{4x}}{\color{#c92786}{-15x}}-20
2
Common factor from the two pairs
3x^{2}+4x-15x-20
x(3x+4)-5(3x+4)
3
Rewrite in factored form
x(3x+4)-5(3x+4)
(x-5)(3x+4)
Solution
Choose the correct algebraic expression for the verbal phrase below.
The product of 10 and f minus 4
4f-10
10(4)
10f-4
So According to me the answer is
10(f-4)
Because it says the product and product means multiply and brackets also means multiply so the product if 10 AND f-4

The graph represents function 1, and the equation represents function 2:
Function 1
A coordinate plane graph is shown. A horizontal line is graphed passing through the y-axis at y = 6.
Function 2
y = 2x + 7
How much more is the rate of change of function 2 than the rate of change of function 1?
1
2
3
4
Answer:
2
Step-by-step explanation:
Linear equation form: y = mx + b
(where m is the slope and b is the y-intercept)
The rate of change for a line is the slope.
Function 1: y = 6
⇒ the slope is zero so the rate of change is zero
Function 2: y = 2x + 7
⇒ the slope is 2 so the rate of change is 2
Therefore, 2 - 0 = 2
So the rate of change of function 2 is 2 more than the rate of change of function 1

Hey!
Let's see... if they walk 10 feet in 6 seconds, then they walk about half a foot a second (0.6 to be exact.)
Multiply 0.6 by 45 and your answer should be.. 27. So, they walk 27 feet in 45 seconds.
Next, we keep multiplying 0.6 by a number over 45, but under 100, and the total amount of time it takes for a penguin to was 45 feet is... 75!
We know this because 75x0.6 is 45. and 75 is the number of seconds it takes to walk 45 feet for the penguin.
Your answer for #1 is 27
Your answer for #2 is 75

12x+6y=120
4x+y=30
Answer:
x=5, y=10. (5, 10).
Step-by-step explanation:
12x+6y=120
4x+y=30
-------------
2x+y=20
4x+y=30
----------------
y=20-2x
4x+(20-2x)=30
4x+20-2x-30
2x-30-20
2x=10
x=10/2
x=5
4(5)+y=30
20+y=30
y=30-20
y=10
Answer:
12x+6y=120
4x+y=30
using elimination method.
12x+6y=120 -----(1) ×4
4x+y=30----------(2) ×12
48x+24y =480
-48x+12y =360
12y =120
y= 10
To get x sub. y for 10 into equation (2)
4x+y=30
4x+10=30
4x=30-10
4x=20
x=5
x=5 , y=10

What is 3 1/4 +3 5/8?
Answer:
6.875 or 6 7/8
Step-by-step explanation:
Because first we add the whole numbers 3 + 3=6
So we have 6 holes.
Now sense our demionters are not the same were going to try to get 4 to 8 so x 2.
sense we times the denominator on 1/4 we have to times 1 by 2 also.
so so now our 1 is a 2.
Next were going to add 2 + 5=7 so out fraction is 6 holes and 7/8
The reason i also said 6.875 is because 7/8=0.875 or 87.5%
So fraction form =6 7/8
decimal form=6.875
And percent form=87.5%
Hope this helps have a great afternoon:)

Seven times a number, x
Step-by-step explanation:
How to complete this problem?
Write out from word format to number format.
We have the word expression:
Seven times a number x.
Seven and x are the two terms included in our expression, and we'll be multiplying both of the terms.
Times is short for multiplying.
When including key words:
'Seven' 'times' 'x'.

a line passes through the origin (3,5) and (-12, b) what is the value of B?
Answer:
b = -20
Step-by-step explanation:
Let's start by finding the slope of the line.
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Origin: (0, 0)
We can use (0, 0) and (3, 5) to find the slope:
[tex]Slope=\frac{5-0}{3-0}=\frac{5}{3}[/tex]
Then, we can plug this into the equation for slope to find the value of b (the slope has to be the same, since they're on the same line)
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{5}{3}=\frac{b-5}{-12-3}\\\frac{5}{3}=\frac{b-5}{-15}\\\text{Multiply both sides by -15}\\\frac{5}{3}(-15)=b-5\\\frac{-75}{3}=b-5\\-25=b-5\\\text{Add 5 to both sides}\\b=-20[/tex]

Express the area and circumference of a circle as functions of the circle’s radius. Then express the
area as a function of the circumference.
The area of a circle as a function of the circumference when calculated from substituting values in their formulas gives the expression written as; A = πC²/4
What is the formula for area and circumference of a Circle?The formula for area of a circle is;
A = πr²
Making area as a function of the radius will give;
r = √(A/π)
Formula for Circumference of a Circle is;
C = 2πr
Thus making Circumference as a function of the radius will give;
r = C/2
Putting C/2 for r in the area formula gives;
A = π(C/2)²
A = πC²/4

The sum of Eric’s and Bob’s weights is 9 times the difference of their weights. The positive difference of their weights is also 240 pounds less than the sum. If Eric weighs less than Bob, find Bob’s weight.
Can you use the elimination method please? Thx
Answer:
150
Step-by-step explanation:
So I will shorten Eric, and Bob's names as E, and B.
So the equations are this
B-E = B+E - 240, E as Eric, and B as Bob, and this E+B=9(E-B)
Move the variables and you get
-2E =- 240
Just divide them both by -2
and E=120
So when we know the value of E we can just plug it into the 1st question
120+B=9B+1080
Moves the Variables and numbers to the other side
8B=1200
1200/8= 150
B=150
There is Bob's weight

6s > 42
DIVIDE 6 to BOTH SIDES
6s/6 > 42/6
CANCEL out: 6/6 because it give you 1
KEEP: 42/6 because it help compare to the s-value
NEW EQUATION: s > 42/6

A set of speakers for a classroom cost 365.23. The school needs to place them in 42 classrooms. How much will it cost to place speakers in all of the classrooms?
Answer:
$15339.66
Step-by-step explanation:
Let's start with what we know,
1 classroom = 1 set of speakers
1 set of speakers = $365.23
The school has 42 classrooms
Find how much it will cost to place the speakers in all of the classrooms
To find the amount it will cost, you will need to substitute values
1 school = 42 classrooms
= 42 sets of speakers
= 42 (365.23)
= 15339.66
It will take $15339.66 to place the speakers in all of the classrooms at the school.

Cones A and B are similar.
The volume of cone A is 1080cm3.
The volume of cone B is 1715cm3.
Calculate the height,
h
, of cone A.
Well it's not possible to find height with knowing cone B's height or radius .Steps provided below if you have pic you can solve by yourself.
Radius is similar in both cones.(Ignore it)Height may be different but they must be similar.The ratio of height to volume remains same .Now put the values and solve for height of h
