Step-by-step explanation:

To better see what the slope is (the coefficient of x), write it in slope-intercept form, y=mx+b. The slope-intercept form of [tex]y -3 = 5(x-2)[/tex] is [tex]y=5x-7[/tex].  The slope is the coefficient of x, which is 5.

Section 1 - Question 9
Frankie argues that the fraction 20 is a rational number because the square root of 20 is 10. Frankie believes that because 10 is a whole number, it is rational
Alejandro disagrees. He believes that 20 is a rational number because the square root falls between 4 and 5, and the decimal terminates.
Which statement BEST describes who is correct?
А
Frankie is correct because the 20 is 10 which is a rational number.
B
Alejandro is correct because the 20 falls between 4 and 5 and the decimal terminates
С
Both students are correct because 20 is a rational number.
D
Neither student is correct because 20 is an irrational number
©2020 Illuminate Education,

Answers

The answer to this question is B

Alejandro is correct because the 20 falls between 4 and 5 and the decimal terminates. Option B is correct.

Given that,
Frankie argues that the fraction 20 is a rational number because the square root of 20 is 10. Frankie believes that because 10 is a whole number, it is rational. Alejandro disagrees. He believes that 20 is a rational number because the square root falls between 4 and 5, and the decimal terminates.

What is a rational number?

Rational numbers are numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3 etc.

Here,
20 is a rational number but its square root is not 10 so, Frankie is not correct.
The square root of 20 falls between 4 and 5 the decimal terminates. its true and Alejandro is correct.

Thus, Alejandro is correct because the 20 falls between 4 and 5 and the decimal terminates. Option B is correct.

A polynomial function has a zero at 4 (multiplicity 3) and 0 (multiplicity 1). Write a function in standard form that can represent this function.

Answers

Answer:

(x^4) - 64x

Step-by-step explanation:

zeros at 4 and 0 are the roots so can be factor as x*(x-4) and the multiplicity tels to what power you have to raise those factors

[tex]x^{1} *(x-4)^{3}[/tex] becuase multiplicity of 1 for root at 0, and multiplicity of 3 at root 4

now to write this in standard form

[tex]x*(x-4)^{3} = \\x*(x-4)(x^{2} +4x+16)= \\(x^{2} -4x)(x^{2} +4x+16) = \\x^{4} +4x^{3} +16x^{2} -4x^{3} -16x^{2} -64x = \\x^{4} -64x[/tex]

Carolina is making punch for a party. She made 6 bowls of punch. Each bowl holds 2 1/2 gallons of punch. 1 gallon is equal to 4 quarts. She thinks each person will drink about 1 quart of punch. How many people will the 6 bowls of punch serve?

Answers

Answer:

60 people

Step-by-step explanation:

Bowls of Punch = 6

Each bowl holds 2 1/2 gallons of punch

6 bowls = 2 1/2 gallons × 6

= 5/2 × 6 gallons

= 30/2

= 15 gallons

6 bowls of Punch = 15 gallons of Punch

1 gallon = 4 quarts

15 gallons = 4 × 15 quarts

= 60 quarts

6 bowls of Punch = 15 gallons of Punch = 60 quarts of punch

She thinks each person will drink about 1 quart of punch.

How many people will the 6 bowls of punch serve?

6 bowls of Punch = 15 gallons of Punch = 60 quarts of punch

60 quarts of punch / 1 person

= 60 people

The 6 bowls of punch will serve 60 people

Keith rented a truck for one day. There was a base fee of $17.99, and there was an additional charge of 97 cents for each mile driven. Keith had to pay $137.30 when he returned the truck. For how many miles did he drive the truck? miles

Answers

Answer:

216 miles

Step-by-step

ex15.95+.73x=173.63

.73x=173.63-15.95

.73x=157.68

x=157.68/.73

x=216 miles driven.

PROOF;

15.95+.73*216=173.63

15.95+157.68=173.63

173.63=173.63

Answer: Keith drove the truck for 123 miles

Step-by-step explanation:

17.99+0.97m=137.30

Subtract 17.99 on both sides:

17.99-17.99+0.97m=137.30-17.99

0.97m=119.31

Divide 0.97 on both sides:

0.97m/0.97=119.31/0.97

m=123 miles

How many values of x solve the equation g(x)=2? How can you illustrate your answer on the graph? Remember, we are not looking for the exact x-values, only how many solutions

Answers

Answer:

3 solutions

Step-by-step explanation:

To solve g(x) = 2

The solutions are at the points of intersection of g(x) and y = 2

y = 2 is the equation of a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 2

If you draw the horizontal line using say (0, 2) and (2, 2)

Then g(x) intersects y = 2 at 3 places

Thus there are 3 solutions to g(x) = 2

75% of the whole is 180. What's the whole?
.

Answers

Solution for What is 75 percent of 180:

75 percent *180 =

( 75:100)*180 =

( 75*180):100 =

13500:100 = 135

Now we have: 75 percent of 180 = 135

Question: What is 75 percent of 180?

Percentage solution with steps:

Step 1: Our output value is 180.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$180=100\%$180=100%​.

Step 4: Similarly, $x=75\%$x=75%​.

Step 5: This results in a pair of simple equations:

$180=100\%(1)$180=100%(1)​.

$x=75\%(2)$x=75%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{180}{x}=\frac{100\%}{75\%}$
180
x​=
100%
75%​​

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{180}=\frac{75}{100}$
x
180​=
75
100​​

$\Rightarrow x=135$⇒x=135​

Therefore, $75\%$75%​ of $180$180​ is $135$

A house sold for $275,100.00. The buyer's real estate agent earned a commission of $11,004.00, and the seller's real estate agent earned a commission of $6,877.50. What was the commission rate of each agent?

Answers

Answer:

Buyer's real estate agent's commission rate = 4%

Seller's real estate agent's commission rate = 2.5%

Step-by-step explanation:

Given that:

Amount for which the house was sold = $275,100.00

Earnings by buyer's Real Estate Agent = $11004.00

Earnings by seller's Real Estate Agent = $6,877.50

To find:

The commission rate of each agent = ?

Solution:

Commission rate can be calculated by finding the percentage for both the real estate agents with the amount for which the house was sold.

i.e.

[tex]\text{Rate of Buyer's agent } = \dfrac{\text{Earnings of Buyer's agent}}{\text{Amount for which the house was sold}}[/tex]

[tex]\Rightarrow \dfrac{\$11004.00}{\$275,100.00}\times 100 = 4\%[/tex]

[tex]\text{Rate of Seller's agent } = \dfrac{\text{Earnings of Seller's agent}}{\text{Amount for which the house was sold}}[/tex]

[tex]\Rightarrow \dfrac{\$6,877.50}{\$275,100.00}\times 100 = 2.5\%[/tex]

Therefore, the answer is:

Buyer's real estate agent's commission rate = 4%

Seller's real estate agent's commission rate = 2.5%

Why can you use the constant of proportionality with any representation?

Answers

Answer:

The number k is called the constant of proportionality. One important way of thinking about this constant k is that it tells us how much y increases by if we increase x by exactly 1. to express that y is directly proportional to x.

Proportionality constant can be used with any representation to determine how a variable is changing with respect to others.

Variation is a method comparing the nature of a variable with another variable using a constant called the proportionality constant

For instance, if a variable y is directly proportional to x, it is expressed as;

y ∝ x

y = kx

k is the proportionality constant relating y to x and shows that as the value of y is increasing, the value of x is also increasing and vice versa.
