Answer:C 6x-18
Step-by-step explanation:
3 times 2 equals 6 and 3 times -6 will give you -18
Answer:
The solution is C) 6x-18
Step-by-step explanation:
3(2x-6)
(we multiply between 3 and in brackets)
3×2x = 6x
3×(-6) = -18
if we combine, then the arrangement is like this:
6x-18
Factor completely x3 – 3x2 - 9x + 27
Answer:
x³ - 3x² - 9x + 27
= x²(x - 3) - 9(x - 3)
= (x² - 9)(x - 3)
= (x -3)(x + 3)(x - 3)
= (x + 3)(x - 3)²

Step-by-step explanation:
how many squares would have to be shaded to that 1/6 of the shape is shaded
Answer:
3 squares
Step-by-step explanation:
Firstly, you have to count the number of squares in the shape. As it can been seen from the diagram, there are a total 18 squares (i.e 6 squares on each row × 3 squares on each column).
Secondly you have to find 1/6 of the total number of the squares in the shape. 1/6 of the total number of the square in the shape = 1/6 × 18 = 3 squares
Therefore 3 squares would have to be shaded so that 1/6 of the shape is shaded

Please help me with this, i just need to solve "b". Ty!
Answer:
15
Step-by-step explanation:
To find the rate of change, find the slope
Slope= [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{35-20}{2-1}\\\\=\frac{15}{1}\\\\=15[/tex]
Write 0.25x+1y=12 in slope-intercept form.
Answer:
y = -.25x + 12
Step-by-step explanation:
Subtract x on both sides.
y = -.25x + 12
There is your answer. The "1" before the y doesn't need to be written, as a rule in algebra, ones do need to be written and are assumed to be there if there is no number at all.
-.25 is the slope and 12 is the y-intercept.
Lincoln High School's basketball team won the regional playoffs scoring a
total of 60 points, not including free throws. The team made a total of 26
baskets; some were 2-point shots, and the rest were 3-point shots. How
many 2-point shots did the team make?
Answer:
y = 8
x = 18
Step-by-step explanation:
(x + y = 26) x2 -1
2x+3y = 60 -2
2x+2y = 52 -1
2x+3y = 60 -2
Subtracting equation 2 from equation 1
= -y = -8
= y = 8
_____________________________________________________
2x+3y = 60
= 2x+3x8 = 60
= 2x+24 = 60
= 2x = 60-24
= 2x = 36
= x = 36/2
= x = 18
Write a power that has a value greater than 140 and less than 145.
Answer:
[tex]12^{2}[/tex]
Step-by-step explanation:
To find: a power that has a value greater than 140 and less than 145
Solution:
Take [tex]x=12^{2}[/tex]
Here,
[tex]12^{2}=144[/tex] and [tex]140<144<145[/tex]
That is [tex]140<x<145[/tex]
Therefore,
[tex]12^{2}[/tex] has a value greater than 140 and less than 145.

What is the length of DF? Round to the nearest hundredth.
Answer:
7.06
Step-by-step explanation:
This triangle can be solved a couple of ways. In the end, they amount to the same thing.
1) The area is ...
A = 1/2bh = 1/2(8)(15) = 60 . . . using DG as the base
Using GE as the base, the height (DF) is ...
A = (1/2)(17)(DF)
2(60)/17 = DF = 120/17
DF ≈ 7.06
__
2) Using similar triangles, we can find the ratio of the long side to the hypotenuse as ...
(long side)/(hypotenuse) = DE/GE = DF/DG
DF = DG(DE/GE) = 8(15/17) = 120/17
DF ≈ 7.06

Which explains whether or not Ming has described a proportional relationship, and why?
Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin.
Ming has not described a proportional relationship. Although it is a linear relationship, it does not pass through the origin.
Ming has not described a proportional relationship. Although it passes through the origin, it is not a linear relationship.

Solve by using substitution -5x-y=12 y=-4x-9
Answer:
(-3, 3)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
-5x - y = 12
y = -4x - 9
Step 2: Solve for x
Substitution
Substitute in y: -5x - (-4x - 9) = 12Distribute negative: -5x + 4x + 9 = 12Combine like terms: -x + 9 = 12Subtract 9 on both sides: -x = 3Divide -1 on both sides: x = -3Step 3: Solve for y
Define original equation: y = -4x - 9Substitute in x: y = -4(-3) - 9Multiply: y = 12 - 9Subtract: y = 3Tickets to a football game cost $6 per ticket write and equation that represents this relationship between tickets purchased and total cost . Use t to represent the number of tickets purchased and c to represent the total cost
Given:
Tickets to a football game cost $6 per ticket.
To find:
The equation that represents this relationship between tickets purchased and total cost.
Solution:
Let t represents the number of tickets purchased and c represents the total cost.
Cost of 1 ticket = $6
Cost of t ticket = $6t
Since, c is the total cost oft tickets, therefore the equation for given situation is
[tex]c=6t[/tex]
Therefore, the required equation is [tex]c=6t[/tex].
Jaylen has a pet grooming business. In 2018, he groomed 200 dogs. In 2019, he groomed 450 dogs. What was the percent increase in the number of dogs groomed? Don't forget your % sign.
Answer:
Percentage increase= 125%
Step-by-step explanation:
Giving the following information:
2018= 200 dogs
2019= 450 dogs
To calculate the percentage increase, we need to use the following formula:
Percentage increase= [(2019 - 2018)/2018]*100
Percentage increase= [(450 - 200)/200]*100
Percentage increase= 125%

11. A large pine tree was struck by lightning and fell as
shown by the diagram below. Which equation
could be used to find the length of the fallen part of
the tree?
8 ft
13 ft —
A. 82 +132 - X
B. N82+132 -
C. 132 - 82 = X
D. V132 - 82 - *
It forms a right triangle.
To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2
This can be rewritten as x = sqrt(a^2 + b^2)
Using the dimensions of the tree the answer would be :
B. x = sqrt(8^2 + 13^2)
The equation to find the length of the fallen part of the tree is
[tex]x=\sqrt{8^2+13^2}[/tex]
Right Triangle.
Right triangles is a triangle with one angle is 90 degree.
The side opposite to 90 degree is the hypotenuse.
Pythagorean Theoremthe sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse .
The length of the fallen part of the tree is the hypotenuse
Hypotenuse is 'x'
Base of the triangle is 13 feet and height is 8 ft
Apply Pythagorean theorem to find out the hypotenuse 'x'
[tex]hypotenuse^2= base^2 + height ^2\\x^2=\sqrt{13^2+8^2} \\x=\sqrt{13^2+8^2}[/tex]
the equation to find the length of the fallen part is
[tex]x=\sqrt{8^2+13^2}[/tex]

Answer:y= (3/4)x -7/4
Step-by-step explanation:
[y -(-1)]/[x - 1] = [2 -(-1)]/[5 - 1]
[y + 1]/[x - 1] = 3/4
y + 1 = (3/4)x - 3/4
y = (3/4)x - 7/4.
