Given:
a = 2 and b = -2.
To find:
The value of [tex]a^3+3b^2[/tex].
Solution:
We need to find the value of expression [tex]a^3+3b^2[/tex] at a = 2 and b = -2.
Substituting a = 2 and b=-2 in [tex]a^3+3b^2[/tex], we get
[tex](2)^3+3(-2)^2[/tex]
[tex]=8+3(4)[/tex]
[tex]=8+12[/tex]
[tex]=20[/tex]
Therefore, the value of expression [tex]a^3+3b^2[/tex] at a = 2 and b = -2 is 20.
Mariana plans to visit an amusement park where she must pay for admission and purchase tickets to go on the rides. Mariana wants to find the total cost for a day at the amusement park. She wrote the equation c = 1.50x + 12 to predict c, the total cost for a day at the amusement park. What could the number 12 represent in Mariana's equation?
Answer: The number 12 represents admission charge in Mariana's equation.
Step-by-step explanation:
As per given ,
Total cost = ( Charge per ticket) (Number of tickets) + (Admission fees) (i)
For x = Number of tickets, the total cost (c) for a day at the amusement park is given as
[tex]c = 1.50x + 12[/tex] (ii)
Here, 12 = Admission fees [Comparing (i) and (ii)]
Hence, the number 12 represents admission charge in Mariana's equation.

This equation shows how the total amount of paper Scott's office has recycled depends on the number of weeks since they started the new recycling plan. p = 12w The variable w represents the number of weeks the office has been on the new recycling plan, and the variable p represents the total kilograms of paper recycled. How many weeks will it take Scott's office to recycle a total of 12 kilograms of paper?
Answer:
1 week
Step-by-step explanation:
Given:
p = 12w
Where,
w = number of weeks the office has been on the new recycling plan
p = total kilograms of paper recycled.
How many weeks will it take Scott's office to recycle a total of 12 kilograms of paper?
Find w when p = 12
p = 12w
12 = 12w
Divide both sides by 12
w = 12/12
= 1
w = 1 week

Miya flips a coin and rolls a 6-sided number cube labled 1-6 and records tge outcome. About how many times is she likely to flip heads and roll a 3 out of 48 trials
Answer:
4 times
Step-by-step explanation:
Sample space :
6 sided cube = (1, 2, 3, 4, 5, 6)
Coin = (H, T)
Probability = required outcome / Total possible outcomes
Probability of head (H) = P(H) = 1 /2 = 0.5
Probability of 3 = P(3) = 1 /6 = 0.166666
Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333
Hence, expected number of times this is likely to occur in 48 tries :
0.083333 * 48 = 4

answer
=5
Answer: 5
Step-by-step explanation:
Multiplying or dividing a negative by a negative results in a positive.
[tex](-10)/(-2)=5[/tex]
Multiplying or dividing a negative by a positive results in a negative.
[tex](-10)/(2)=-5[/tex]
Multiplying or dividing a positive by a negative results in a negative.
[tex](10)/(-2)=-5[/tex]
Multiplying or dividing a positive by a positive results in a positive.
[tex](10)/(2)=5[/tex]
Thus, because -25 and -5 are both negatives, the answer must be positive.

Solve for c.
2(c +1) = 10
Answer:
c = 4
Step-by-step explanation:
[tex]2(c+1) = 10[/tex]
Lets divide both the sides by 2.
[tex]=> \frac{2 (c+1)}{2} = \frac{10}{2}[/tex]
[tex]=> c + 1 = 5[/tex]
Now , lets substract 1 on both the sides.
[tex]=> c + 1 - 1 = 5 - 1[/tex]
[tex]=> c = 4[/tex]
The solution to the equation 2(c + 1) = 10 is c = 4.
We have,
To solve for c in equation 2(c + 1) = 10, we will apply the distributive property and simplify the equation step by step.
Let's solve it:
Distribute the 2 to the terms inside the parentheses:
2c + 2 = 10
Move the constant term (2) to the right side by subtracting 2 from both sides of the equation:
2c + 2 - 2 = 10 - 2
Simplifying further:
2c = 8
Divide both sides of the equation by 2 to solve for c:
(2c) / 2 = 8 / 2
Simplifying further:
c = 4
Therefore,
The solution to the equation 2(c + 1) = 10 is c = 4.

A pair of jeans cost $200, but is on sale for 40% off. You still have to be 7%
tax. What is your final cost for the jeans?
$128.40
O
$120
$111.60
280
Answer:
$128.40
Step-by-step explanation:
200 × 0.4 = 80
200 - 80 = 120
120 × 0.07 = 8.4
120 + 8.4 = 128.4
Answer:
$128.40
Step-by-step explanation:
1. Find the cost after the discount.
Multiply the original cost by the discount percentage. This is the amount that was taken off of the original price.
$200 x 40% = $80
Subtract the discount from the original price.
$200 - $80 = $120.
2. Calculate the tax.
Tax is 7% of the final cost. Multiply the final cost by the tax rate. This determines how much tax was added.
$120 x 7% = $8.40
Add the tax amount to the discounted price.
$120 + $8.40 = $128.40
The final cost is $128.40.
Use the remainder theorem to determine if x = 2 is a zero of the following polynomial, and find the quotient and the remainder.
p(x) = x3 + 24x2 + 108x - 320
Answer:
(A) Yes, x = 2 is a zero of the polynomial.
The quotient is x² + 26x + 160 and the remainder is 0
Step-by-step explanation:
Given;
p(x) = x³ + 24x² + 108x - 320
Using remainder theorem to test if x = 2 is a zero of the given function
p(2) = (2)³ + 24(2)² + 108(2) - 320
= 8 + 96 + 216 - 320
= 0
Thus, x = 2 is zero of the function
(ii) to get the quotient and the remainder of the given function, divide the function by 'x - 2'
x² + 26x + 160
x - 2 √ x³ + 24x² + 108x - 320
- (x³ - 2x²)
0 + 26x² + 108x - 320
- (26x² - 52x)
0 + 160x - 320
- (160x - 320)
0 + 0
The quotient is x² + 26x + 160
The remainder is 0
Thus, the correct option is A.
Yes, x = 2 is a zero of the polynomial.
The quotient is x² + 26x + 160 and the remainder is 0

Select all true statements.
A) Dilation's of an angle must be congruent to the original angle.
B) Dilation's if a triangle must be congruent to the original triangle.
C) Dilation's of a segment must be congruent to the original segment.
D) Dilation's of a circle must be congruent to the original circle.
Answer:
A) Dilation's of an angle must be congruent to the original angle.
B) Dilation's if a triangle must be congruent to the original triangle.
Step-by-step explanation:
Dilation is one of rigid transformations in which the size of an angle or object is either increased or decreased, to produce an image, with respect to a given factor. In this process, the dimensions of the object are affected but its orientation remains the same.
When a figure is dilated, the new figure is congruent to the original figure. Also, when an angle undergoes dilation, its measure is not affected. Thus, it would be congruent to the original angle.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x - 5y = 13
x + 4y = 10
Step 2: Rewrite Systems
x + 4y = 10
Subtract 4y on both sides: x = 10 - 4yStep 3: Redefine Systems
3x - 5y = 13
x = 10 - 4y
Step 4: Solve for y
Substitution
Substitute in x: 3(10 - 4y) - 5y = 13Distribute 3: 30 - 12y - 5y = 13Combine like terms: 30 - 17y = 13Isolate y terms: -17y = -17Isolate y: y = 1Step 5: Solve for x
Define equation: x + 4y = 10Substitute in y: x + 4(1) = 10Multiply: x + 4 = 10Isolate x: x = 6Answer:
(6,1) x=6 and y=1
Step-by-step explanation:
EASY we can use Elimination or Substitution process
We are going to solve by
Elimination process
Subtract each other
(3x-5y=13)
(x+4y=10)
3x-5y=13;x+4y=10
To solve this multiply (x-4y=10) by 3 to get rid of the x
3x-12y=30
now u can subtract both
3x-12y=30 minus
3x-5y=13
17y=17
Divide both sides by 17
y=1
Now we have y lets plug it in to find x
x+4(1)=10
x+4=10
subtract 4 from both sides
x=6
x=6 and y=1
