Find the equation of the line that passes through the points (-1,8)
and (2, -1). Write your equation in slope-intercept form. Show all
work to support your answer.

Answers

Answer 1

Answer:  

y = -3 * x + 5

 

Step-by-step explanation:  

We start with the equation for slope-intercept y = mx + b -  

Y is any y point on the line. X is any x point on the line. M is the slope of the line. B is the y-intercept of the line.  

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -  

(8 - (-1)) / ((-1) - 2)  

9 / (-3)  

Slope = -3  

Now we insert the slope into the equation -  

y = -3 * x + b  

As said before, Y is any y point on the line and X is any x point on the line, so we can choose a random point and insert it in to find the y-intercept -    

-1 = -3 * 2 + b  

-1 = -6 + b  

b = 5

The y-intercept of the line is (0, 5)  

We insert the y-intercept in the equation -  

y = -3 * x + 5  

y = -3 * x + 5 is our answer to the problem.

The organizers of a conference needs to prepare at least 200 notepads for the event

and have a budget of $160 for the notepads. A store sells notepads in packages of 24

and packages of 6.

24x + 6y > 200

This system of inequalities represent these constraints:

(16x + 5.40y = 160

Answers

The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160

Inequalities shows the non equal comparison of numbers or expressions.

Let x represent the number of packages of 24 notepads and y represent the number of packages of 6 notepads

Since the organizers need to do at least 200 notepads, hence:

24x + 6y > 200

Also, they have a budget of $160. Let us assume that each 24 package cost $16 and each 6 package cost $5.40, hence:

16x + 5.40y ≤ 160

The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160

Given f(x)=2x+1 and g(x)=7-x. Find g(f(x)).

Answers

Answer:

f(g(x)) = 2(7 - x) + 1

Step-by-step explanation:

f(x) = 2x + 1

g(x) = 7 - x

The question in the picture itself says to find f(g(x)) so i'll find that instead

f(g(x)) = 2(7 - x) + 1

f(g(x)) = 14 - 2x + 1

f(g(x)) = -2x + 15

Can anyone help me with this please I really need help with this rq .

Answers

Answer:

Step-by-step explanation:

g(x) = ax - b

-76 = 27a - b

-79 = 28a - b           Subtract

3 = -a                       Multiply both sides by  -1

a = -3

g(x) = -3x - b

-85 = -3*30 - b

-85 = - 90 - b          Add 90 to both sides

90-85 = - b             Combine

5 = - b                     Multiply both sides by - 1

-5 = b

g(x) = -3x - b

g(x) = -3x - (-5)

g(x) = - 3x + 5

X is 2 because 10 x 2 equals 20 -3 equals 17

Answer:

x=2

Step-by-step explanation:

To solve for x, you want to isolate it. To do this, move terms that are NOT x and use the opposite operation to get it to the other side.

10x - 3 = 17

(Add 3 to both sides)

10x = 20

Now isolate x (since 10x is really 10 * x, you divide)

10x=20

x=2

This is how you would solve to get the solution.

If 4 gallons of milk cost $16.24, how much would 7 gallon of milk cost

Answers

Answer:

$28.42

Step-by-step explanation:

First let's calculate the cost per gallon.

We can do this by simply dividing the cost of 4 gallons by 4

1 gallon of milk cost 16.24/4 = 4.06

We want to find the cost of 7 gallons.

We can easily do this by multiplying the cost of one gallon by 7

7 gallons of milk cost 7 * 4.06 = $28.42
