9x²+9y²-x
Step-by-step explanation:Combining like terms
-9x is a different term than 9x^2 however 9x is like terms with x. Coefficients really are the only thing that are excused for like terms
Now with that out of the way,
1 - Rewrite
9x²+3y²+6y²-x
This step becomes more useful as you go on in algebra as organization will soon start to correlate how fast you complete problems correctly
2 - Find like terms
9x² does not have any like terms
+3y² is like terms with +6y²
-x does not have a like term
3 - Combine like terms
9x²+(3y²+6y²)-x
↓
9x²+9y²-x
Hope this helps :)

On a piece of paper, use a protractor to construct a triangle with angle measures of 60° and 80°. I Which statements about this triangle are true? Select all correct answers.
Answer:
Option A
Option C
Option D
Step-by-step explanation:
Triangle attached in image~
A) It is an acute triangle (Yes)
Before we put reasonings why this is true, let's find the missing angle in the triangle.
⇒ 60 + 80 + x = 180°⇒ 140 + x = 180°⇒ x = 180 - 140⇒ x = 40°This triangle is an acute triangle because all angles in the triangle are acute, as 80°, 60°, 40° are acute angles.
B) Two sides have the same length (No)
Two sides can only be the same if two angles are equivalent. Since all angles are different, two sides cannot have the same length.
C) All sides have different lengths (Yes)
Since all angles are unalike, the triangle has different side lengths.
D) The third angle measures 40° (Yes)
⇒ 60 + 80 + x = 180°⇒ 140 + x = 180°⇒ x = 180 - 140⇒ x = 40°Answer:
A
C
D

Please help solving this ! Which net represents the figure?
Answer:
upper right
Step-by-step explanation:
The net for a figure is a representation of all of the figure's faces. The polygons in the net are joined on an edge corresponding to a common edge between the faces they represent.
The given figure is a rectangular prism. Its faces are only rectangles. All nets that have triangles in the net can be eliminated from consideration.
The appropriate choice is the one attached.

Paul can paint 119 doors in 8 hours, while Scott can paint 54 doors in 4 hours. Who can paint the doors faster, Paul or Scott?
A. Paul
B. Scott
Answer:
See below
Step-by-step explanation:
You need to find the unit rate, which is found by dividing the number of doors, in this case, by time.
119/8=14.875
54/4=13.5
Paul can paint doors faster.

find the measure of angle b. (alternate exterior = 134 degrees)
Answer:
b=59
Step-by-step explanation:
The Theorem for Alternate Exterior angles is: If two parallel lines are cut by a transversal then the alternate exterior angles are congruent.
By this theorem we now know that b=59 degrees.
Use the angle relationship in the figure below to solve for x. Assume that line A and line B are parallel, line C is a transversal and the given angles are given in
degrees
AC
4x+29
12x+55
B
Answer:
x = 6
Step-by-step explanation:
The 2 angles given are same- side interior angles and are supplementary, thus
4x + 29 + 12x + 55 = 180, that is
16x + 84 = 180 ( subtract 84 from both sides )
16x = 96 ( divide both sides by 16 )
x = 6

Factor this polynomial 15c^3 + 10c^2 - 40c
Answer:
5c(3c-4)(c+2)
Step-by-step explanation:
We can factor the GFC out
15c^3+10c^2-40c
5c(3c^2+2c-8)
Then we can factor by quadratic trinomials
5c(3c-4)(c+2)
No receives a $5 discount each month on his cell phone bill because he signed up for autoplay from his bank account over the last eight months nor has pay a total of $284 for his cell phone bill what would Noah be charged for his cell phone bill each month if he stopped using autoplay?
Answer:
$36Step-by-step explanation:
Normally Noah is expected to pay an amount without a discount.
let this amount be x
so the amount paid monthly after the discount is removed is (x-5)
Noah paid this amount for 8 months
(x-5)*8=248
solving for x we will get the amount that Noah is expected to be charged when he stopped using the autoplay
(x-5)*8=248
8x-40=248
8x=248+40
8x=288
divide both sides by 8 we have
x=288/8
x=$36
y=4-2x^3 a linear equation
Answer:
False
Step-by-step explanation:
the highest degree of the equation is 3, meaning that the equation is NOT linear.
Write an equation to represent each relationship 23 more than 10 times a number is the same as 5 more than the number
Answer:
23 + 10x = x + 5

Keeping car tires inflated is essential to safe driving. For one type of car tire, the tire pressure in pounds per square inch (psi) is assumed to be approximately Normal, with a mean of 35 psi and a standard deviation of 2 psi. What percentage of tires are inflated to a pressure above 36 psi?
Answer:
30.854%
Step-by-step explanation:
First, we find the z-score corresponding to the value given
z-score = (x - mean)/SD
Z-score = (36-35)/2 = 1/2 = 0.5
we find the Probability of (x > 0.5)
we use the standard normal distribution table for this
P( x > 0.5) = 0.30854
This has a percentage 30.854%
Answer:
30.854%

Which is a function and not a function
Answer:
Function: A, C, F, H,I
NOT: B,D,E,G
Step-by-step explanation:
To be a function every x is only allowed to pair up with one y. If there's no repeated x's, then its a function. If x repeats, it has to have the same y as the first time it showed up. If a vertical line (up and down) touches a graph in more than one place, its NOT a function. Any y can partner up with however many x's it wants to, doesn't matter, its still a function. But to be a function ONLY ONE y for each x. Life's not fair.

The students in Ms. Baca's art class were mixing yellow and blue paint. She told them that two mixtures will be the same shade if the blue and yellow paint are in the same ratio. How many different shades of paint did the students make?
Answer:
Two shades will be prepared.
Step-by-step explanation:
Ms Baca told the students that when two colors yellow and blue are mixed in the same ratio same shade is prepares.
From the table attached,
If A is a mixture of 1 part yellow and 2 parts of blue color,
Ratio of the colors = 1 : 2
If B is a mixture of 2 parts yellow and 3 parts of blue color,
Ratio of the colors = 2 : 3
If C is the mixture of 3 parts yellow and 6 parts of blue color,
Ratio of the colors = 3 : 6 = 1 : 2
If D is a mixture of 4 parts yellow and 6 parts of blue color,
Ratio of the colors = 4 : 6 = 2 : 3
If E is a mixture of 6 parts yellow and 9 parts of blue color,
Ratio of the colors = 6 : 9 = 2 : 3
Therefore, mixtures A, C will create the same shade while mixtures B, D, E will be of same shade but different from A and C.
Two shades of the paints will be made by the students.

what is the answer to this question
Answer:
x = 1
Step-by-step explanation:
the axis of symmetry is a vertical line passing through the vertex or turning point of the parabola with equation
x = c ( c is the x- coordinate of the vertex )
the vertex is at (1, 0 ) with x- coordinate 1 , then
equation of axis of symmetry is x = 1
A sports analyst determines that the number of points scored in a basketball game is related to the number of shots taken during the game. The least-squares regression line is y = 5. 0 + 1. 2x, where y is the predicted number of points scored and x is the number of shots taken. In one game, a team takes 50 shots and the residual is –10. How many points were scored by this team in this game?
45
55
65
75
Answer:
65
Step-by-step explanation:
y= 5.0 + 1.2x
when x = 50
y = 5.0 + 1.2 x 50
= 5.0 + 60
= 65
The value of y is 65 when x = 50, or the number of points the team was scored was 65.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A sports analyst determines that the number of points scored in a basketball game is related to the number of shots taken during the game.
y= 5.0 + 1.2x
Plug x = 50
y = 5.0 + 1.2 x 50
= 5.0 + 60
= 65
Thus, the value of y is 65 when x = 50, or the number of points the team was scored was 65.

If 10 percent of x is 20 what is 23 percent of x
Answer: 46%
Step-by-step explanation:
x / 10 = 20
x / 10 x 10 = 20 x 10
x = 200
23% = 23/100 = 46/200
46%
