Answers
Answer:
c= 14-7i-zdi
d=14/zi - 7/z - c/zi
Step-by-step explanation:
Solve for c by simplifying both sides of the equation, then isolating the variable.
Solve for d by isolating the variable by dividing each side by factors that dont contain the variable.

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.

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.

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?
Answers
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

Put the following equation of a line into slope-intercept form, simplifying all fraction. 5x-y=(-4)
Answers
You would have to reorder.
For this you need to isolate y.
First subtract 5x from both sides.
This would result in: -y = -4 - 5x
Then multiply both sides by negative one to make the y positive.
This would result in: y = 5x + 4

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
Answers
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
Write an equation in slope-intercept form with the following information. Goes through the points (6, 2) and (7, 5).
Slope= _____ y-intercept=_____
Answers
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

i had this question yesterday
Answer:
the slope is -400
Step-by-step explanation:
In order to find the slope, we must use the slope equation
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
where it was considerated 2 points of the line, i.e.,
(x_1,y_1) and (x_2,y_2)
In this case, we observe that there are 2 "easy" points,
(x_1,y_1)=(0,4000) and
(x_2, y_2)=(10,0)
By substituying these point in the slope equation, one has
m=[tex]\frac{0-4000}{10-0}[/tex]
m=[tex]\frac{-4000}{-10}[/tex]
Hence, m=-400.

Step-by-step explanation:
Given parameters:
Cost of ingredient = $9.75
Number of people = 6 people
Unknown:
How much will it cost to serve 24 people = ?
Solution:
To solve this problem, let us find the rate of each recipe per person;
Rate = [tex]\frac{Number of people }{Cost of ingredient}[/tex]
Insert parameters and solve;
Rate = [tex]\frac{6}{9.75}[/tex] = 0.62people/$
For 24 people, it will cost;
Cost of ingredient = [tex]\frac{Number of people }{rate}[/tex]
Cost of ingredient = [tex]\frac{24}{0.62}[/tex] = $39

Answers
a^2 + b^2 = c^2
18^2 + 24^2 = c^2
18 and 24 are both divisible by 6, so you can divide them both by 6 to make the equation easier to solve.
3^2 + 4^2 = c^2
25 = c^2, so c = 5
Multiply 5 by the 6 we divided by earlier to get a hypotenuse of 30.
The area equals base times height divided by two, so we can divide 84 by 2 and then multiply by 30 to get the area.
84/2= 42
42 x 30 = 1260 inches squared is the area

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?
Answers
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.
