Answer:
-3y2-8+5y2-1=
2y2-9
Step-by-step explanation:
Answer:
[tex]\huge{\boxed{\sf{ 2y^{2} - 9 }}}[/tex]
Step-by-step explanation:
[tex]( - 3y^{2} - 8 ) - ( - 5y^{2}+ 1 )[/tex]
While subtracting , sign of each term of the second expression changes.
⇒[tex]- 3y^{2} - 8 + 5y^{2} - 1[/tex]
Combine like terms : [tex]-3y^{2}[/tex] and [tex]5y^{2}[/tex]
Like terms are those which have the same base.
⇒[tex]2y^{2} - 8 - 1[/tex]
Remember : The negative integers are always added but posses the negative ( - ) sign.
⇒[tex]2y^{2} - 9[/tex]
Hope I helped!

4. 35%
Step-by-step explanation:
91*70%=63.7
125-43.75=81.25
100/125= 0.8*43.75=35
P=2l+2w
20=2l+2(2.5)
20=2l+5
-5 -5
15=2(l)
/2 /2
7.5=l

-25 = -3x + 2
4x - 2 = 18
3- 6x + 5 + 10x - 1
Answer:
Ok, so if the top line (-25 = -3x + 2) is separate and the second line is separate (4x - 2 = 18) then the answer is x = 9 and x = 5

Answer:
f(x) = x³ + x² - 22x - 40
Step-by-step explanation:
Given that x = a is a zero of f(x) then (x - a) is a factor
Here the zeros are x = - 4, x = - 2, x = 5 , then the factors are
(x + 4), (x + 2) and (x - 5)
The function is then the product of the factors, that is
f(x) = (x + 4)(x + 2)(x - 5) ← expand the first pair using FOIL
= (x² + 6x + 8)(x - 5) ← distribute
= x³ + 6x² + 8x - 5x² - 30x - 40 ← collect like terms
= x³ + x² - 22x - 40

Answer: The answer is b 100+(-500)
Step-by-step explanation: If you solve for the original and this answer, they will both equal -400
Answer
The answer is B.
Step-by-step explanation:

Step 2: 100-500= -400
also because
A=600
C= 600
D= -600

B is the logical choice
The slope of the line is 1 The graph represents one side of the roof of a building 16 14 12 101 Vertical Distance (feet) 8 2 x 1 2 3 4 5 6 7 8 Horizontal Distance (feet)
A slope is also known as the gradient of a line. The slope of the line is 7/2.
What is Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
slope = (y₂-y₁)/(x₂-x₁)
The two of the points that lie on the line are (0,0) and (4,14). Therefore,
The slope of the line is,
Slope, m = (14-0)/(4-0) = 14/4 = 7/2
Hence, the slope of the line is 7/2.

Distributive Property 1
2(x+3)
What is the answer
Answer:
Step-by-step explanation:2x +6
Answer:
2x+6
Step-by-step explanation:
Definition - To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Other examples-
5(4x+5) -------> You would distribute(Multiply) 5 into 4x+5
5 times 4x is equal to 20
5 times 5 is equal to 25
The sign is addition
Thus, 20x+25
Hope you understand the distributive property and hope this helps!

Find three consecutive even integers such that the sum of the smallest number and twice the middle number is 20 more than the largest number.
Answer:
10, 12, 14Step-by-step explanation:
Consecutive even integers increase by 2.
x ← an integer
2x ← an even integer (the smallest)
2x+2 ← next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 ← the last even integer consecutive to 2x+2 (the largest)
2(2x+2) ← twice the middle number
2x+2(2x+2) ← the sum of the smallest number and twice the middle
2x+4+20 ← 20 more than the largest number
2x + 2(2x + 2) = 2x + 4 + 20
2x + 4x + 4 = 2x + 24
-4 -4
6x = 2x + 20
-2x -2x
4x = 20
÷2 ÷2
2x = 10
2x+2 = 10+2 = 12
2x+4 = 10+4 = 14

Thomas draws figure F and its dilation, figure F9. What is the scale factor? WELP PLZ HELP
Answer:
Option (C)
Step-by-step explanation:
Formula to get the scale factor of any image from it's preimage,
Scale factor of an image = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the preimage}}[/tex]
From the figure attached,
F' is the image of preimage F after dilation.
Scale factor = [tex]\frac{\text{Length of A'B'}}{\text{Length of AB}}[/tex]
= [tex]\frac{4}{6}[/tex]
= [tex]\frac{2}{3}[/tex]
Therefore, Figure F has been dilated by a scale factor of [tex]\frac{2}{3}[/tex] to form F'.
Option (C). will be the answer.

Leanor pays a total of $16.50 for every 6 shirts she has dry-cleaned. Which graph models a
relationship with the same unit rate?
Answer:
Graph (F)
Step-by-step explanation:
Leanor pays a total of $16.50 for every 6 shirts she has dry cleaned.
Unit rate to dry clean the shirts will show the slope of the line plotted for price Vs number of shirts dry cleaned.
Unit rate = [tex]\frac{16.5}{6}[/tex] = $2.75 per shirt
≈ $2.8 per shirt
From the given graphs attached,
Slope of the line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Graph (F)
Slope = [tex]\frac{25}{9}=2.78[/tex]
≈ 2.8
Graph (G)
Slope = [tex]\frac{50}{3}=26.67[/tex]
Graph (H)
Slope = [tex]\frac{20}{2}=10[/tex]
Graph (J)
Slope = [tex]\frac{45}{2}[/tex] = 22.5
Therefore, graph (F) will be the answer.

In which of the following drawings is DE parallel to AC?
Answer:
Option (C)
Step-by-step explanation:
In this question we will use the property " similarity of the triangles".
If DE and AC are parallel two triangles BED and BCA will be similar, corresponding sides of the triangles will be proportional.
[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]
Option (A).
[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]
[tex]\frac{22+12}{12}=\frac{14+26}{14}[/tex]
[tex]\frac{34}{12}=\frac{40}{14}[/tex]
[tex]\frac{17}{6}=\frac{20}{7}[/tex]
But [tex]\frac{17}{6}\neq \frac{20}{7}[/tex]
Therefore, given triangles are not similar.
AC and DE are not parallel.
Option (B).
[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]
[tex]\frac{25}{25-7}=\frac{21+9}{21}[/tex]
[tex]\frac{25}{18}=\frac{30}{21}[/tex]
[tex]\frac{25}{18}=\frac{10}{7}[/tex]
But [tex]\frac{25}{18}\neq \frac{10}{7}[/tex]
Therefore, AC and DE are not parallel.
Option (C).
[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]
[tex]\frac{22.5+15}{15}=\frac{40}{40-24}[/tex]
[tex]\frac{37.5}{15}=\frac{40}{16}[/tex]
2.5 = 2.5
Therefore, AC║DE.
Option (D).
[tex]\frac{\text{BA}}{\text{BD}}=\frac{\text{BC}}{\text{BE}}[/tex]
[tex]\frac{17.5+5}{17.5}=\frac{20.4+6}{20.4}[/tex]
[tex]\frac{22.5}{17.5}=\frac{26.4}{20.4}[/tex]
[tex]\frac{9}{7}=\frac{22}{17}[/tex]
But [tex]\frac{9}{7}\neq \frac{22}{17}[/tex]
Therefore, AC and DE are not parallel.
Option (C) will be the answer.
