NEED ASAP Triangle XYZ is similar to triangle PDQ. The measures of the angles in triangle XYZ are shown in the table. What is the measure of angle D?
Answer:
measure angle D = 62
Step-by-step explanation:
as the sum of measures of triangle =180
then (8x-40)+(4x-10)+(3x+20)=180
15x-30=180
x=(180+30)/15=14
XYZ SIMILAR TO PDQ
Y=D=3*14+20=62
How do i solve tis in need help
slope=2/7 y-intercept=-4
Answer:
y=2/7x-4
Step-by-step explanation:
Write in Slope intercept form
y=mx+b
m = slope
b = y intercept
x = x intercept
y = (0,-4)
So,
y = 2/7x+(-4) substitute
y = 2/7x-4

do –2(3x – 1) = –6x – 1 have one solution
Answer:
No solutions
Step-by-step explanation:
–2(3x – 1) = –6x – 1
First distribute the left side
-6x + 2 = -6x - 1
Add 1 to both sides
-6x + 3 = -6x
Add 6x to both sides
3 = 0
This equation is not true because 3 does NOT equal 0. Therefor, this equation has no solutions.
Answer:
there is no solution
Step-by-step explanation:
There are no values of x that make the equation true.

Prove AED is equal to DEB. Do not use vertical angle theorem
Answer:
Step-by-step explanation:
From the figure attached,
Given:
Lines AB and CD are intersecting each other at a point E.
To prove:
∠ACB ≅ ∠DEB
Statements Reasons
1). ∠AEC + ∠BEC = 180° 1). Linear pair theorem
2). ∠DEB + ∠BEC = 180° 2). Linear pair theorem
3). ∠AEC + ∠BEC = ∠DEB + ∠BEC 3). Transitive property of equality
4). ∠AEC = ∠DEB 4). Subtraction property of equality
What is the value of g(-9) for the function g(x) = x2 - x?
Answer:
72Step-by-step explanation:
Given the function;
g(x) = x^2 - x
We are to find g(-9)
g(-9) = (-9)² - 9
g(-9) = 81 - 9
g(-9) = 72
hence the value of g(-9) is 72
Given the function
f(x)=-1/2(1-x)^2,
find f(-5).
Answer:
f(x)= -1/2(1-x)^2
replacing x with -5 since -5 was given as the function
f(-5)=-1/2(1-5)^2
according to bodmas we solve what is in the bracket first
f(-5)=-1/2(-4)^2
f(-5)=-1/2(16)
-1/2*16/1
-16/2=-8
find the composition of transformations that map ABCD to EHGF
Answer:
(x - 1, y + 1 )
Step-by-step explanation:
Consider the reflection in the y- axis
A point (x, y ) → (- x, y )
Consider the reflection of point A
A(- 5, 2 ) → A'(5, 2 )
Now A → E after the transformations
E = (4, 3 ), thus
A'(5, 2 ) → E(4, 3 )
(x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )
The translation rule is (x, y ) → (x - 1, y + 1 ).
What is Translation?In mathematics, translation is a transformation that moves every point of a figure or a graph the same distance and in the same direction. The object being translated retains its size and shape, but its position changes.
Consider the reflection in the y- axis
A point (x, y ) → (- x, y )
Consider the reflection of point A
A(- 5, 2 ) → A'(5, 2 )
Now A → E after the transformations
E = (4, 3 ), then
A'(5, 2 ) → E(4, 3 )
Thus, the translation rule is (x, y ) → (x + (- 1), y + 1 ) = (x - 1, y + 1 )

Tuition for one year at a state university is about $13,000. Devon would like to attend this university and will save money each month for the next 4 years. His parents will give him $5,200 for his first year of tuition. Which plan shows the minimum amount of money Devon must save to have enough money to pay for his first year of tuition?
Answer:
$162.50 per month for the next 4 years
Step-by-step explanation:
Here are the options to this question :
Save $270.83 per month for the next 4 years
Save $162.50 per month for the next 4 years
Save $650.00 per month for the next 4 years
Save $108.33 per month for the next 4 years
If Devon's parents would give him $5,200 for his first year of tuition, Devon needs to save a minimum of :
$13,000 - $5,200 = $7,800
If he saves per month for the next four months, he would save 48 times ( 12 months in a year multiplied by 4 years)
The minimum he should save per month = $7800 / 48 = $162.50

The volume of a sphere with a radius of 3 cm is 14.3 cm³.
What is a sphere?In geometry, a sphere is a three-dimensional solid figure, which is round in shape.
The surface area is 4πr².
The volume is (4/3)πr³.
The diameter is 2×radius of the sphere.
We know a glope is in the form of a sphere.
We also know that the volume of a sphere is (4/3)πr³.
Therefore, The volume of a sphere with a diameter 3 cm Or a radius of
(3/2) cm has a volume,
= (4/3)π(3/2)³ cm³.
