Jesse runs a 26-mile race in 5 hours. LJ runs a 15-mile race in 2 hours. Who runs at a slower rate?
Answer: Jesse
because i guess i divided the number you could do it however 15 divided by 2 = 7.5 and 26 divided by 5 = 5.2
Answer:
Jesse is the slower rate.
Step-by-step explanation:
The slower rate is going to be determined by the distance divided by the time.
Jesse: 26 / 5 = 5.2 miles / hour
LJ: 15 / 2 = 7.5 miles / hour
Jesse is the slower rate.

Which rules define the function graphed below?
y = x; y = 5
y = x + 2; y = 5
y = x; x = 5
y = x + 2; x = 5
Answer:
B) y=x+2; y=5
Step-by-step explanation:
The rules that define the graphed function are y = x + 2; y = 5
How to determine the rule of the function?The function is a piecewise function
There are two lines on the graph.
The first line has the following points
(0,2) and (3,5)
Express 2 and 5 as a sum of 2
(0,0 + 2) and (3, 3 + 2)
This means that the y value is the sum of 2 and the x value.
So, we have:
y = x + 2
The other line has a constant value of 5 for all x values
So, we have:
y = 5
Hence, the rules that define the graphed function are y = x + 2; y = 5

Which expressions are polynomials??
Answer:
Options (1) and (2)
Step-by-step explanation:
Properties of a polynomial,
1). A polynomial having division by a variable can't be defined as a polynomial.
Example:
(y² + [tex]\frac{x}{1+x}[/tex])
2). A polynomial can't have a negative exponent.
Example : [tex](x^{-2}+y-6)[/tex]
3). Polynomials don't have the radicals.
Example : y² + x√3
4). A polynomial can't have a fraction exponent.
Example : [tex]x^2+x^{\frac{1}{2}}-1[/tex]
By these properties, Options (3) and (4) are not the polynomials.
Options (1) and (2) are the correct options.

Jess is painting his car. He's created a purple color that uses red paint and blue paint in a ratio of 6:5. Jess uses 15
pints of blue paint. How many pints of paint does he use in total?
A
18
B
33
С

D
26
Answer:
B.) 33
Step-by-step explanation:
15/5=3
6x3=18
18+15=33
The ratio shows how many times one value is contained in another value.
If the ratio of Red and blue is 6:5 and uses 5 pints of blue color.
The total pints of paint used in total is 33 pints.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
The ratio of minutes and minutes in 1 hour is 60 : 3600
We have,
Purple color:
Red : Blue = 6 : 5
Let,
Red colour = 6x
Blue color = 5x
Now,
Blue color = 15 pints
5x = 15 pints
x = 15/3
x = 3 pints _______(1)
Now,
Total color.
= Red + Blue
= 6x + 5x
= 11x
Now,
From (1) we get,
= 11x
= 11 x 3
= 33
Thus,
If the ratio of Red and blue is 6:5 and uses 5 pints of blue color.
The total pints of paint used in total is 33 pints.

Kelly and Daniel surveyed 6 of their friends to find the number of pets in each of their households. They recorded the results from each home in a list. 4, 1, 2, 1, 0, 1 What is the mean absolute deviation of this data set? Enter your answer in the box.
Answer:
67
Step-by-step explanation:
Answer:
The mean absolute deviation is 1
Step-by-step equation =
Take all of the numbers and add them together.
4+1+2+1+0+1= 9
Then divide by how many numbers there are. In this word problem its 6.
Divide 9 by 6.
9 ÷ 6 = 1.5
So 1.5 would be our mean.
To find the mean absolute deviation subtract our mean and our original numbers.
1.5 - 4 = 2.5
1.5 - 1 = 0.5
1.5 - 2 = -0.5
1.5 - 1 = 0.5
1.5 - 0 = 1.5
1.5 - 1 = 0.5
Add all of those numbers together.
2.5 + 0.5 + 0.5 + 0.5 + 1.5 + 0.5 = 6
Even though one of the numbers was a negative answer we add it as a positive because the mean absolute deviation can never be negative
Divide by the amount of numbers you added.
6 ÷ 6 = 1
So the mean absolute deviation is 1

Your air conditioner hasn’t been working properly, so you decide to set up an appointment to have it fixed. The repair company tells you that it costs $99 for a one time service fee plus $50 every hour. The technician came to your house and determined the drain was clogged. The total bill came to $549. Write an equation that represents this situation. (do not use any spaces in your equation & use the letter "x" to represent your variable)
Answer:
[tex]99 + 50x = 549[/tex]
Alternatively you can write it as;
[tex]50x - 450 = 0[/tex]
Step-by-step explanation:
One time service fee=$99
Rate of service=$50/hour
let unknown hours=x
Therefore the equation is
[tex]99 + 50x = 549[/tex]
or you can further simplify it to:
[tex]50x - 450 = 0[/tex]
And you can then solve for x to be 9 hours.

Answer: C. x=-8,14
Step-by-step explanation:
C
Answer:
x = 14, –8Step-by-step explanation:
|x – 3| = 11
(x - 3) = 11 - (x - 3) = 11
x - 3 = 11 - x + 3 = 11
x = 11 + 3 -x = 11 - 3
x = 14 -x = 8
x = -8

We have
f(-3) = (-3)² - 2(-3) + 7
= 9 + 6 + 7

write the inverse of f(x) = x + 5
Answer:
f^-1(x) = x - 5
Step-by-step explanation:
f(x) = x + 5
y = x + 5
x = y + 5
y = x - 5
f^-1(x) = x - 5
Answer:
f^ -1(x) = x - 5
Step-by-step explanation:
y =x+5
To find the inverse, exchange x and y
x = y+5
Solve for y
Subtract 5 from each side
x-5 = y+5-5
x-5 = y
The inverse is x-5

Given point (-6, -2) and a slope of 5, write an equation in slope-intercept form.
Answer:
y = 5x + 28
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5 , thus
y = 5x + c ← is the partial equation
To find c substitute (- 6, - 2) into the partial equation
- 2 = - 30 + c ⇒ c = - 2 + 30 = 28
y = 5x + 28 ← equation of line
