Answer:
D
Step-by-step explanation:
To multiply
(5x² - 6x + 2)(4x² - 3x)
Each term in the second factor is multiplied by each term in the first factor, that is
5x²(4x² - 3x) - 6x(4x² - 3x) + 2(4x² - 3x) ← distribute parenthesis
= 20[tex]x^{4}[/tex] - 15x³ - 24x³ + 18x² + 8x² - 6x ← collect like terms
= 20[tex]x^{4}[/tex] - 39x³ + 26x² - 6x → D

3.) d
b/c the rule for x-axis is (x,y) --> (x, -y)
One of the points is (1, 1) ==> (1, -1)
4.) The rule for y-axis is (x, y) --> (-x, y)
A(-5, 3) --> A'(5, 3)
B(2, 6) --> B'(-2, 6)
C(-1, -7) --> C'(1, -7)
PAGE 2
5.) The rule for x-axis is (x,y) --> (x, -y)
A(-5, 3) ---> A'(-5, -3)
B(2, 6) ---> B'(2, -6)
C(-1, -7) ---> C'(-1, 7)
6.) The rule for 90 degrees clockwise is (x, y) --> (y, -x)
B(3, 4) ---> B'(4, -3)
PAGE 3
1.) On the transitions right is positive and left is negative
So 2 units to the right = +2
And 9 units down = - 9
So (x, y) --> (x + 2, y - 9)
2.) A is wrong b/c that translation is (x, y) ---> (x + 3, y -3)
B is wrong b/c the translation is (x, y) ---> (x + 3, y + 3)
C is wrong b/c the translation is (x, y) ---> (x - 3, y + 3)
D is correct b/c the translation is (x, y) --->(x -3 , y -3)
A(6, 6) --> A'(3, 3) B(7, 4) --> B'(4, 1) C(4, 4) --> C'(1, 1)
PAGE 4
7.) The rule for 90 degrees rotation counterclockwise is (x, y) --> (-y, x)
The correct graph would show A(-3, 3) ----> (-3, -3)
The only graph that shows this is Graph C
8.) The rule for 180 degrees rotation is (x, y) ----> (-x, -y)
The correct graph would show A(-3, 3) ----> A'(3, -3)
Graph B is the only one that ALL the angles follow this rule
PAGE 5
9.) It is Dilation with the center at the origin and a scale factor of 2.
B/c --> A(3, 3) ---> A'(6, 6) B(2, 0) ---> B'(4, 0) C(5, 2) ---> C'(10, 4)
(3*2= 6, 3*2=6) (2*2= 4, 0*2= 0) (5*2= 10, 2*2= 4)
10.) It is Dilation with the center at the origin and a scale factor of 1/3
B/c ---> A(-3, 6) --> A'(-1, 2) B(12, 3) ----> B'(4, 1) C(-6, -6) ---> C'(-2, -2)
(-3*1/3= -1, 6*1/3= 2) (12*1/3= 4, 3*1/3= 1) (-6*1/3= -2, -6*1/3= -2)

Step 1:
- 2y - 9 = - 11 Equation
Step 2:
- 2y = - 2 Add 9 on both sides
Step 3:
y = - 2 ÷ - 2 Divide 2 on both sides

Consider the triangle (in which angle4 is present)
by angle sum property,
20 + 40 + angle4 = 180
60 + angle4 = 180
angle4 = 180 - 60
angle4 = 120
Also,
angle2 = 120 (vertically opposite angles)
angle1 + angle2 = 180 (linear pair)
angle1 + 120 = 180
angle1 = 180 - 120
angle1 = 60
The price of a ticket, in dollars, on the local commuter train can be determined from the expression 2.75 + 0.50(s), where s is the number of stops for which the passenger will be on the train. Use this expression to find the price of a ticket to ride the train for 13 stops.
Answer:
$9.25
Step-by-step explanation:
2.75+ .5(13)
.50 (13)= 6.5
6.5 +2.75= 9.25

Find m2WXY

mZWXY = |
Answer:
m∠WXY is 142°
Step-by-step explanation:
The measure of the exterior angle at one vertex of a triangle equals the sum of the measures of the opposite interior angles to this vertex
In ΔXYZ
∵ ∠WXY is an exterior angle at the vertex X
∵ ∠Y and ∠Z are the opposite interior angles to the vertex X
→ By using the rule above
∴ m∠WXY = m∠Y + m∠Z
∵ m∠WXY = (2x - 2)°
∵ m∠Y = x° and m∠Z = 70°
→ Substitute them in the equation above
∴ 2x - 2 = x + 70
→ Subtract x from both sides
∵ 2x - x - 2 = x - x + 70
∴ x - 2 = 70
→ Add 2 to both sides
∵ x - 2 + 2 = 70 + 2
∴ x = 72
→ To find the m∠WXY, substitute x by 72 in its measure
∵ m∠WXY = 2(72) - 2
∴ m∠WXY = 144 - 2
∴ m∠WXY = 142°
The number of hours Hannah practices each week is 3 hours less than twice the number of hours Darcy practices. If n represents the number of hours Darcy practices, which expression below represents the number of hours Hannah practices?
Answer:
2n-3
Step-by-step explanation:
n represents the number of hours Darcy practices.
The number of hours Hannah practices each week is 3 hours less than twice the number of hours Darcy practices.
Twice the number of hours Darcy practices is 2n.
Hannah practices for : 2n-3
Hence, the expression that represents the number of hours Hannah practices is "2n-3".

I hope this helped, please mark brainliest
Answer: 12
Work: You need to use the PEMDAS Rule. The first thing you do is 5 x 4. After doing that, your new equation is 30 - 20 + 2. After doing that equation, you get 12.

Verizon offers a cell phone plan where customers buy a cell phone for $300 and pay a monthly fee of $40. T- Mobile offers a cell phone plan where customers buy a cell phone for $200 and a monthly rent of $60. Write the equation needed to find the number of months a customer would have to own a cell phone in order for the two cell phone companies to be equal. PLEASE ANSWER QUICKLY. need help!!!
Answer:
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
Step-by-step explanation:
Given that:
Cost of cell phone at Verizon = $300
Monthly fee = $40
Let,
x be the number of months
V(x) = 40x + 300
Cost of cell phone at T-mobile = $200
Monthly fee = $60
T(x) = 60x + 200
For equal amount of money,
V(x) = T(x)
40x+300=60x+200
300-200=60x-40x
100=20x
20x=100
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{100}{20}\\x=5[/tex]
Hence,
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.

Harper is making pudding cups for a big celebration. She made 5 pounds of pudding, but she needs to separate the pudding into individual 4-ounce cups. How many total individual pudding cups can Harper make?
Given :
Total amount of pudding made, T = 5 pounds.
Size of each cup, s = 4 ounces.
To Find :
How many total individual pudding cups can Harper make.
Solution :
Let, n number of pudding cups can filled with 5 pounds pudding.
We know, 1 pound = 16 ounces.
So, 5 pounds = 16×5 = 80 ounces.
Now,
[tex]n = \dfrac{80}{s}\\\\n = \dfrac{80}{4}\\\\n = 20 \ cups[/tex]
Therefore, 20 cups can be filled with 5 pounds of pudding.
