Step-by-step explanation:
The function that represents the cost of pizza with toppings as follows :
y = 2x+8 ...(1)
Where x = 0,1,2 and 3
Here, y depends on x it means y depends on x. y is a dependent variable and x is independent variable.
Domain is the set of input values and range is the output values.
Domain = 0,1,2 and 3
Now, put x = 0 in function (1)
y = 2(0)+8 = 8
Put x = 1 in function (1)
y = 2(1)+8 = 10
Put x = 2 in function (1)
y = 2(2)+8 = 12
Put x = 3 in function (1)
y = 2(3)+8 = 14
So, the range of the function is 8,10,12,14.

A bag contains 15 marbles. The probability of randomly selecting a green marble is One-third. The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is StartFraction 1 over 15 EndFraction. What is the probability of randomly selecting a red marble
Answer:
1/5
Step-by-step explanation:
Total Number of Marbles in the bag = 15
The probability of randomly selecting a green marble is 1/3
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble = 1/15
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is calculated as
The probability of randomly selecting a green marble × The probability of randomly selecting a red marble
Hence:
1/15 = 1/3 × R
1/15 = R/3
Cross Multiply
R × 15 = 1 × 3
R= 3/15
R= 1/5
Hence, the probability of randomly selecting a red marble is 1/5
The length of Carl's hair was 9 3/4 inches. After his hair cut, the length was 6 1/2 inches . How many inches did he cut?
Answer: 3 1/4 inches
Step-by-step explanation:
9 3/4 - 6 1/2
I turned 6 1/2 into an easier fraction so it can be easier to subtract. Now the expression is:
9 3/4 - 6 2/4
6 2/4 is equivalent to 6 1/2
I then got 3 1/4

GOODLUCKKKKKKFind $\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1}$
Answer:
1Step-by-step explanation:
Given the expression [tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1}[/tex]
According to indices:
[tex]a^{-1} = \frac{1}{a}[/tex]
Applying this to the question:
[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{1}\left\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right}[/tex]
Hence:
[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]}{\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]} \\\\\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = 1[/tex]

Answer:
the three vertices are (1, 1), (2, 0), (-1, -3).
The vertices of the triangles are the coordinates of the point of
intersection of the graph of the equation of the three lines.
Correct response:
The coordinates of the three vertices of the triangles are;
E. [tex]\underline{(2, 0), \ (1, -1), \ and \ (-1, -3)}[/tex]
How are the coordinates of the vertices obtained?The equation of the given lines are;
y = -x + 2, y = 2·x - 1, y = x - 2
The point of the intersection of the two lines, gives the vertices, and are
the solution of the two linear equations of the lines.
At the points where the lines intersect, we have;
-x + 2 = 2·x - 1
Which gives;
3·x = 3
x = 1
y = -1 + 2 = -1
A vertex is at the point (1, -1)
The coordinate of the second vertex is given as follows;
2·x - 1 = x - 2
2·x - x = -2 + 1 = -1
x = -1
y = -1 - 2 = -3
The second vertex is; (-1, -3)
The coordinates of the third vertex is given as follows;
-x + 2 = x - 2
2·x = 4
x = 2
y = 2 - 2 = 0
Which gives the point; (2, 0)
The three vertices are; E. (2, 0), (1, -1), and (-1, -3)Learn more about linear equations here:

3x^2 – 10x = 8
(it’s to the 2nd power btw)
Answer:
x = 4, (-2/3)
Step-by-step explanation:
3(x^2) – 10x = 8
3(x^2) – 10x - 8 = 0
(3x + 2)(x - 4) = 0
(3x + 2) = 0
3x = -2
x = (-2/3)
(x - 4) = 0
x = 4
Answer:
x = -2/3, 4
Step-by-step explanation:
move all terms to one side
3x^2 - 10x - 8 = 0
split the terms in 3x^2-10x-8 into two terms
3x^2+2x-12x-8=0
factor out common terms in first to and last to
x(3+2)-4(3x+2) =0
factor out common term 3x+2
(3x+2) (x-4)=0
solve for x
x=-2/3,4

Mr. Fitch needs to get a loan to replace the air-conditioning system in his home. The cost of the replacement, including installation, is $4,348.00. He can apply for a 5- year loan or a 3-year loan. Both loans involve simple interest with an annual interest rate of 6.5%. If Mr. Fitch applies for the 5-year loan, how much more will he pay in interest than with the 3-year loan? F. $704.98 G. $565.24 H. $2,260.96 J. $56,524.00
Answer: g
Step-by-step explanation:
4348x.065=282.62
282.62x5=1413.1
282.62x3=847.86
1413.1-847.86=565.24
Compared to a 3-year loan he has to pay G. $565.24 more for a 5-year loan.
What is simple interest?We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, Mr. Fitch needs to get a loan to replace the air-conditioning system.
He can apply for a 5- year loan or a 3-year loan. Both loans involve simple interest with an annual interest rate of 6.5%.
Here, p = $4,348.00, r = 6.5%, t₃ = 3 and t₅ = 5.
For, t₃.
SI₃ = (4348×6.5×3)/100.
SI₃ = $847.86.
For, t₅.
SI₅ = (4348×6.5×5)/100.
SI₅ = $1,413.1.
So, the amount of interest he will have to pay more is (SI₅ - SI₃).
= $(1,413.1 - 847.86).
= $565.24.
