Answer:
b. m = 2, b = 4
Step-by-step explanation:
y = mx + b
m = slope and b = y-intercept
The slope is 2 cause it's going up 2 squares while only going to the right one square each time, so u could right 2/1 but it's not necessary so just 2. And the intercept is 4 because that's where the line intercepts the y-axis.
The temperature drops 2°F every hour. Make a table and write an equation to represent the total temperature drop over time.
A contestant on the biggest loser lost 78.8 pounds over a period of two months. At the end of the two month period, the contestant weighed 194.3 pounds. How much did the contestant weigh when the show began?
Answer: The contestant weighed 73.1 pounds when the show began.
Step-by-step explanation:
Given: A contestant lost 78.8 pounds over a period of two months.
At the end of the two month period, he weighed 194.3 pounds.
Initial weight = weight at the end of the two month period + weight lost by contestant
= 194.3 +78.8 pounds
= 273.1 pounds
Hence, the contestant weighed 73.1 pounds when the show began.

Answer:
Work shown below!
Step-by-step explanation:
d = 7, e = 9, f = 10
4. 29 - d = 29 - 7 = 22
5. 41 + e = 41 + 9 = 50
6. 16f = 16(10) = 160
g = 24, h = 5.5, j = 2.5
7. h + j = 5.5 + 2.5 = 8
8. h - j = 5.5 - 2.5 = 3
9. [tex]\frac{g}{h-j} =\frac{24}{5.5-2.5} =\frac{24}{3}=8[/tex]
k = 24, m = 5.5, n = 2.5
10. km = (24)(5.5) = 132
11. 3n = 3(2.5) = 7.5
12. [tex]\frac{k}{3}=\frac{24}{3}=8[/tex]
p = 24, q = 5.5, r = 2.5
13. p + 23 = 24 + 23 = 47
14. r - 1.8 = 2.5 - 1.8 = 0.7
15. [tex]\frac{pq}{r}=\frac{24*5.5}{2.5} =\frac{132}{2.5}=52.8[/tex]

What is the quotient of x and three increased by 12 = 20
Answer:
x= 24
Step-by-step explanation:
Quotient means divide, increased means add
x/3 + 12 =20
Subtract 12 from each side
x/3 +12-12 = 20-12
x/3=8
Multiply each side by 3
x/3 * 3 =8*3
x= 24
Answer:700 / n, the quotient of 700 and a number. 2w, two times a ... h - 3, three less than a number ... 20 + m, 20 more than a number. x - 12, a number decreased by 12.

Claire accepted a new job at a company with a contract guaranteeing annual raises. Let S
S represent Claire's salary after working for n
n years at the company. The table below has select values showing the linear relationship between n and S. Determine how many years Claire would have to work at the company before her salary would reach $77000.
Answer:
6 years
Step-by-step explanation:
First, you need to write an equation for this problem. I'll write it in slope intercept:
y = mx + b
where m is the slope and b is the y-intercept
To find m, do (change in y/change in x):
using (2, 59000) and (5, 72500),
(72500 - 59000) / (5 - 2)
= 13500 / 3
= 4500
So we have y = 4500x + b
To find b, plug in one of the points into the equation with the slope:
using (2, 59000),
y = 4500x + b
59000 = 4500(2) + b
59000 = 9000 + b
50000 = b
So now you have an equation: y = 4500x + 50000. Now that there is an equation, just insert the given y-value and solve:
when y = 77000
y = 4500n + 50000
= 77000 = 4500x + 50000
= 27000 = 4500x
= 6 = x
So, when Claire's Salary is 77000, her number of years at the company is 6.
what is the solution to the system of equations?
Answer:
No solution
Step-by-step explanation:
[tex]-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9\\\\[/tex]
Lets consider the equation 2.
Here we multiply the LHS and RHS with (-1).
[tex]-3x-4y-3z=-7\\-(2x-6y+2z)=-3\\5x-2y+5z=9\\\\[/tex]
Hence,
[tex]-3x-4y-3z=-7\\-2x+6y-2z=-3\\5x-2y+5z=9\\\\[/tex]
When we add the equations we get,
[tex]0x+0y+0z=-10+9\\Hence,\\0=-1[/tex]
As 0 doesn't equal to -1, answer is d) No solution
if triangle ABC are congruent, what is the length of line segment AB?
Assuming you meant to say triangle ABC is congruent to triangle DEF, then the corresponding pieces AB and DE are the same length.
In short AB = DE.
Since DE = 10, this makes AB = 10 also.
You have been contracted to replace a countertop in a kitchen. You will get paid $1,000 to do the job. You can complete the job in three days working 8 hours a day. You will need to pay the cost of the materials, which is $525, with the $1,000 that you receive to do the job. How much will you be paid per hour for your time?
Answer:
$19.79 cents (rounded to the nearest cent)
Step-by-step explanation:
first subtract the amount needed for materials from your total pay
(1000 - 525 = 475)
take 475 and divide that among the hours you work.
475 / 24 = 19.7916666
round that number to the closest money value
19.79
x/2-4/5+x/5+3x/10=1/5
Answer:
x = 1
Step-by-step explanation:
Given
[tex]\frac{x}{2}[/tex] - [tex]\frac{4}{5}[/tex] + [tex]\frac{x}{5}[/tex] + [tex]\frac{3x}{10}[/tex] = [tex]\frac{1}{5}[/tex]
Multiply through by 10 ( the LCM of 2, 5 and 10 ) to clear the fractions
5x - 8 + 2x + 3x = 2 , that is
10x - 8 = 2 ( add 8 to both sides )
10x = 10 ( divide both sides by 10 )
x = 1

Write an equation in slope-intercept form with the following information. Goes through the points (6, 2) and (7, 5).
Slope= _____ y-intercept=_____
Answer:
The slope is 3
y-intercept is -16
Step-by-step explanation:
Let's start by using the slope formula, [tex]m=\frac{y2-y1}{x2-x1}[/tex]
plug in the points for the relating x and y and solve,
[tex]m\frac{5-2}{7-6}[/tex] this simplifies to [tex]\frac{3}{1}[/tex] or "3"
we have our slope: 3/1 or "3"
the equation needed to find the y-intercept is y=mx+b
We will need to solve for "b" to figure out the y-intercept.
let's plug in any pair of x and y, i'll just choose (6,2)
2=3(6)+b, 2=18+b, 2-18=18-18+b, -16=b
Y-intercept is -16

The distance d in miles that a car travels in t hours at a rate of 58 miles per hour is given by the quation d=58t. What is the best estimate of how far a car travels in 7 hours.
A. About 405 miles
B. About 406 miles
C. About 407 miles
D. About 408 miles
Answer:
the answer is be B 406 miles
Answer: B)
Step-by-step explanation: because
d= miles
t= hours
the car travels 58 miles per hour which gives us d=58t
Now it asks what is the best estimate the car travels within 7 hours so you would multiple 58x7=406
