5. A triangle has side lengths 3x2 + 5x –1, 6x2 + 5, -7x +1.
Which of the following expressions represents the perimeter of the triangle?
A. 9x2 + 2x + 5
B. 9x2 – 2x + 5
c. 9x2 + 2x + 4-1
D. 9x2 – 5x + 7x + 5
Answer:
option B. 9x² – 2x + 5x
Step by step explanation:
The perimeter of a triangle is the sum of all its three sides.
3x²+5x–1+6x²+5–7x+1
= 9x²–2x+5

What is the slope and the y-intercept for the
equation = −2 − 2?
Answer:
So the slope is -2 while the y-intercept is -2
Step-by-step explanation:
y=mx+b
so you need to rearrange it so it will be
y=-2x-2
So m is slope so it is -2
and -2 is b which is the y-intercept so it is -2
Hope this helps and sorry I took so long
Find the slope of the line that passes through (4,8) and (2, 1)
Please help
Answer: (7,2)
Step-by-step explanation below.
Hello!
First, we need to put it in the y2-y1/x2-x1 form.
8-1/4-2 = 7/2
So the slope would be...
m = 7/2
So the line would go up 7 and right 2.
Hope this helps you!

Quadrilateral ABCD is translated to get quadrilateral A’B’C’D’. Vertex A is at (-5, 2), and vertex A’ is at (2, -2). Quadrilateral ABCD is translated blank. If vertex B is at (-6, 5), then vertex B’ is at blank
Answer:
vertex B' is at (1, 1)
Step-by-step explanation:
Let us revise the rules of translation of a point
If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated horizontally to the left by h units then its image is (x - h, y) ⇒ T (x, y) → (x - h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k)→ (x + h, y) ⇒ T (x, y) → (x, y + k)If the point (x, y) translated vertically down by k units then its image is (x, y - k) ⇒ T (x, y) → (x, y - k)Let us use the rules to solve our question
∵ Vertex A = (-5, 2)
∵ Vertex A' = (2, -2)
→ The coordinates of the two points changed which means the
quadrilateral is translated horizontally and vertically
∵ The x-coordinate of A = -5
∵ The x-coordinate of A' = 2
→ Which means it moves to the right, so use the first rule above
∴ the rule of translation is T (x, y) → (x + h, y)
∴ x → x + h
∵ x = -5 and x + h = 2
∴ -5 + h = 2
→ Add 5 to both sides
∴ -5 + 5 + h = 2 + 5
∴ h = 7
∴ The quadrilateral is translated 7 units right
∵ The y-coordinate of A = 2
∵ The y-coordinate of A' = -2
→ Which means it moves down, so use the 4th rule above
∴ the rule of translation is T (x, y) → (x, y - k)
∴ y → y - k
∵ y = 2 and y - k = -2
∴ 2 - k = -2
→ Add K to both sides
∴ 2 - k + k = -2 + k
∴ 2 = -2 + k
→ Add 2 to both sides
∴ 2 + 2 = -2 + 2 + k
∴ 4 = k
∴ The quadrilateral is translated 4 units down
→ Let us find B'
∵ T (x, y) → (x + h, y - k) is the rule of translation
∵ B = (-6, 5)
∵ h = 7 and k = 4
∴ B' = (-6 + 7, 5 - 4)
∴ B' = (1, 1)
∴ vertex B' is at (1, 1)
Quadrilateral ABCD is translated 7 units right and 4 units down. If vertex B is at (-6, 5), then vertex B′ is at (1, 1)

Answer:
x = 2.125 + 0.375y
Step-by-step explanation:
Simplifying
8x + -3y = 17
Solving
8x + -3y = 17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
8x + -3y + 3y = 17 + 3y
Combine like terms: -3y + 3y = 0
8x + 0 = 17 + 3y
8x = 17 + 3y
Divide each side by '8'.
x = 2.125 + 0.375y
Simplifying
x = 2.125 + 0.375y

Answer:
(2,1)
Step-by-step explanation:
multiply by negative three on the first equation then solve
Answer:
(-2, 1)
Step-by-step explanation:
Given:
2x+8y=4...(1)
6x-y=-13...(2)
You would want to have an x or a y value that equals the same in both equations. In this case, we can multiply equation 1 by 3 so that both x's in each equation equal 6x.
(2x+8y=4) x 3...(1)
6x-y=-13...(2)
becomes...
6x+24y=12...(3)
6x-y=-13...(4)
As you can see here, both x's in this equation are equal.
Now we will be combining these equations together. Take the equal x values and make sure they will equal 0. You do that by either subtracting the entire equation or adding it. In this problem, we will be subtracting it because 6x-6x=0
(6x+24y=12) - (6x-y=-13) = 25y =25
Now that we can solve for y separately, 25y=25 y=1
To solve for x, just substitute y into one of the original equations (equations 1 or 2). For this problem, I'll use equation 1.
6x-y=-13
6x-1=-13
6x=-12
x=-2

if each side of the cube shown above has the same length as the measured side what is the approximate volume of the cube
Answer:
The measured side is not shown, so i will answer in a general way.
A cube is a 3-dimensional object with 6 square faces.
You know that all the sides of a square have the same length, then is the same for the cube.
To calculate the volume of a cube, we start with the area of the base.
The base is a square of sidelength L (Suppose that L is the length of the measured side)
The area of the base is:
A = L^2.
To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).
And the height of the cube is also L.
Then the volume is:
V = L*a = L^3

What does the word “flip” tell you to do in “keep change flip” for dividing fractions a) change the place of the numbers numerator and the denominator for the first fraction b) change the places of the numbers in the numerator and the denominator for the second fraction c) change the places of the numbers in the numerator and the denominator for both fractions d) change the ÷ between the fractions
Answer:
b) change the places of the numbers in the numerator and the denominator for the second fraction
Step-by-step explanation:
In the phrase "keep change flip":
You "keep" the first fraction.
"Change" the division sign into a multiplication sign.
"Flip" (or switch) the places of the numerator and denominator in the second fraction.
Example:
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]
[tex]\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5[/tex]

Put the following equation of a line into slope intercept form, simplifying fractions
Answer:
y = - [tex]\frac{1}{5}[/tex] x - 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x + 20y = - 180 ( subtract 4x from both sides )
20y = - 4x - 180 ( divide all terms by 20 )
y = [tex]\frac{-4}{20}[/tex] - [tex]\frac{180}{20}[/tex] , that is
y = - [tex]\frac{1}{5}[/tex] x - 9 ← in slope- intercept form

simplify 8/9/20 please
The value of 8/9/20 could be either 0.04 or 17.77.
What is a fraction?In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, the fraction is the division of the two numbers but the division is not wholly complete.
In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.
It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.
Given the fraction,8/9/20
Case 01)
(8/9)/20 = 0.888/20 = 0.044.
Case 02)
8/(9/20) = 8/0.45 = 17.77.
Hence "The value of 8/9/20 could be either 0.04 or 17.77".
