A line with a slope of 3 passes through the points (-8,f) and (-9,7). What is the value of f

Answers

Answer 1

Answer:

Step-by-step explanation:

Slope can be calculated by:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

We know M, y1, x2, and x1. We want to calculate for y2

[tex]\frac{f-7}{-8-(-9)} = 3\\\frac{f-7}{1} = 3\\f-7 = 3\\f = 10\\[/tex]

Answer 2

Answer: f = 10

Step-by-step explanation: Start with the slope formula.

m = y₂ - y₁ / x₂ - x₁

Plugging the given information into the

slope formula, we get 3 = 7 - f / -9 - (-8).

This simplifies to 3 = 7 - f / -1.

Multiply both sides of the equation by -1 to get -3 = 7 - f.

Solving from here, you be should be able to easily find that 10 = f.

Remember, it's very easy to check your

answer to these kinds of problems.

Since 10 = f, you can plug a 10 back in for f in the original problem.

Then check to see if the line that passes through the points

(-8, 10) and (-9, 7) really does have a slope of 3.

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]

Step-by-step explanation:

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.

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.

Put the following equation of a line into slope-intercept form, simplifying all fraction. 5x-y=(-4)

Answers

Slope intercept form is y = mx + b
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

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

Pythagorean Theorem question

Answers

To find the area, you first must find the hypotenuse of the top triangle.
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.

Use the inequalities to describe the shaded area on the grid​

Answers

Answer:

x≥-2

y<3

y≥x+3

Step-by-step explanation:

For x≥-2 the line is passing through -2 on the X axis

For y<3 the dotted line is passing through 3 on the y axis and as it is dotted it is just less than

For y≥x+3 the line is passing through -3 on the x axis and 3 on the y axis so it must be y=x+3. Then you apply the inequality so it becomes y≥x+3

Hope it helps :)

The inequalities to describe the shaded area on the grid​ are

[tex]\rm \bold {x\geq -2}\\\bold{y<3}\\\\bold{y \geq\ x+3}[/tex]

The shaded area of the grid is surrounded by three lines the equations of all three lines are given as below in form of inequalities.

For a solid line the " equality"  is included but for a dashed line " equality" is not included.

x ≥ -2

y < 3

The equation of third line can be found out by writing standard form of straight line

[tex]\rm y = mx +c \\m = Slope \;of\; the\; line\\c = y\; axis \; intercept \; value[/tex]

As we can observe from the figure that the line passes through (0,3) and (-3,0) and hence we write the equation of line as

[tex]\rm y = (3-0) /(0-(-3)) ( x+3) \\y = 1\times x + 3\\y = x+3 \\So \; the\; inequality\; can \; be\; written\; as\\y\geq x+3[/tex]

Since the area above the line y = x+3 is of our concern hence greater than equal to sign is used.

So the inequality for third line is

[tex]\rm\bold{ {y\geq x+3}}[/tex]

The inequalities to describe the shaded area on the grid

[tex]\rm \bold {x\geq -2}\\\bold{y<3}\\\\bold{y \geq\ x+3}[/tex]

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

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.

Answers

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.
