Answer:

The equation of the linear function is f(x) = -3x - 4

Step-by-step explanation:

The form of the equation of the linear function is f(x) = m x + b, where

m is the slope of the line which represent the functionb is the y-intercept which is value f(x) at x = 0

The rule of the slope is m = Δy/Δx, where

Δx = x2 - x1 and Δy = y2 - y1(x1, y1) and (x2, y2) are two points on the line

f(x) = y

∴ The coordinates of any point belongs to the function are (x, y)

f(-4) = 8 and f(2) = -10

∴ The points are (-4, 8) and (2, -10)

∵ x1 = -4 and y1 = 8

∵ x2 = 2 and y2 = -10

→ Find Δx and Δy

Δx = 2 - (-4) = 2 + 4 = 6

Δy = -10 - 8 = -18

→ Substitute them in the rule of the slope

∵ m = [tex]\frac{-18}{6}[/tex]

m = -3

→ Substitute it in the form of the equation above

f(x) = -3x + b

→ To find b substitute x by -4 and f(x) by 8

∵ 8 = -3(-4) + b

∴ 8 = 12 + b

→ Subtract 12 from both sides

∵ 8 - 12 = 12 - 12 + b

-4 = b

→ Substitute it in the equation

∴ f(x) = -3x + (-4)

∴ f(x) = -3x - 4

The equation of the linear function is f(x) = -3x - 4

Isabelle, Joel, and Bryan sat on their grandmother's porch shelling peas for dinner. There were 2 big bowls of peas, and each person shelled an equal amount. How many bowls of peas did each person shell?

Answers

Answer:

2/3 bowls of peas

Step-by-step explanation:

Given that there were 2 big bowls of peas, and each person shelled an equal amount. Since there are three persons, the ratio of the number of bowls of peas available to the number of persons will give the number of  bowls of peas did each person shell.

Hence each person must have shell

= 2/3 bowls of peas

Find the value of x, giving reasons for your answer:

Answers

Answer:

x = 55

Step-by-step explanation:

[tex](x + 40) \degree = (150 - x) \degree \\ (vertical \: \angle s) \\ \\ x + 40 = 150 - x \\ \\ x + x = 150 - 40 \\ \\ 2x = 110 \\ \\ x = \frac{110}{2} \\ \\ x = 55[/tex]

Answer:

x = 55°

Step-by-step explanation:

When any 2 lines intersect each other at one point , the vertically opposite angles are always equal. Hence ,

[tex]150 - x = x + 40[/tex]

[tex] = > x + x = 150 - 40[/tex]

The slope, m, of a linear equation can be found using the formula m = StartFraction y 2 minus y a Over x 2 minus x 1 EndFraction., where the x- and y-values come from two ordered pairs, and (x1, y1) and (x2, y2).

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the points

(x₁, y₁)(x₂, y₂)

Using the formula  to determine the slope between (x₁, y₁) and (x₂, y₂) of the linear function

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

For example, let the points be

(x₁, y₁) = (1, 2)

(x₂, y₂) = (3, 4)

Determining the slope between

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [4 - 2] / [3 - 1]

               = 2 / 2

               = 1

Thus,

The slope of the line between the points (1, 2)  and (3, 4)  will be: m = 1

Frank Catton, the general manager of Billybob's floating raft hotel and Casino in Tunica Mississippi, has installed the "The Wheel of Doughnuts" at the check in desk. When you check in, you spin the wheel and a plate containing that many hot

doughnuts is delivered to your room the next moming for free. If your spinlands on an orange slot you get free hot chocolate too

(Give a fraction or round to 1 decimal place)

A. What is the probability that you get 7 doughnuts and hot chocolate? I

8. What is the probability that you get 7 doughnuts or hot chocolate?

Answers

Answer:

P( 7 doughnuts or hot chocolate)=0.40

Step-by-step explanation:

From the question we are told that

Total number of plates [tex]n=10[/tex]

1)Generally the probability that you get 7 doughnuts and hot chocolate is mathematically given as

7 doughnuts and hot chocolate= 1 slot

Therefore

P( 7 doughnuts and hot chocolate)= 1/10

P( 7 doughnuts and hot chocolate)= 0.10

2)Generally the probability that you get 7 doughnuts or hot chocolate is mathematically given as

P( 7 doughnuts or hot chocolate)=P(7 doughnuts)+P(hot chocolate)-P( 7 doughnuts and hot chocolate)

1 plates contains 7 doughnuts

P(7 doughnuts)=1/10

P(7 doughnuts)=0.10

4 plates contain hot chocolate

P(hot chocolate)=4/10

P(hot chocolate)=0.4

7 doughnuts and hot chocolate= 1 slot

P( 7 doughnuts and hot chocolate)= 1/10

P( 7 doughnuts and hot chocolate)= 0.10

Therefore

P( 7 doughnuts or hot chocolate)=0.10+0.4-0.10

Therefore

P( 7 doughnuts or hot chocolate)=0.40

The probability of getting 7 doughnuts or hot chocolate is 0.4

Juan and Ari went to the farmers market to buy fruit. Juan’s bag of apples that he bought weighed 31/7 pounds. Ari’s bag of oranges that she bought weighed 19/3 pounds. Using compatible fractions, estimate how much heavier Ari's bag is compared to Juan's bag.

A) 1 and one-half pounds

B) 2 pounds

C) 6 pounds

D) 10 and one-half pounds

Answer:

B: approximately 2 pounds

Step-by-step explanation:

Juan’s bag weighed 31/7 pounds

Ari's bag weighed 19/3 pounds.

We are told to use compatible fractions to determine the difference. Thus we have to make sure the denominator is the same;

For Juan, let's multiply both numerator and denominator by 3 to get; 93/21 pounds

For Ari, let's multiply both numerator and denominator by 7 to get; 133/21

Thus, difference is;

(133/21) - (93/21) = 40/21

This gives;

1.9 pounds heavier

This is approximately 2 pounds

Answer:

B. 2 pounds

Including Jose, there are eight people in his family. If order matters, how many ways can he arrange his family members into a row of five seats if Jose must sit in the first seat?

Answers

Answer:

840 ways

Step-by-step explanation:

From the above question, we are told that order matters, hence, to solve the above question, we use the Permutation formula.

P(n, r) = nPr = n!/(n -r)!

From the above question,

Since Jose is included in the 8 people and he takes the first seat

n = 8 - 1 = 7 people

r = 5 - 1 = 4 seats

This is because, once Jose takes the first seat, there are 4 seats left with 7 people waiting to be seated

Hence,

7P4 = 7!/(7 - 4)!

7P4 = 7!/3!

7P4 = 5040/6

7P4 = 840 ways

Answer:

840

June needs at least $575 to go on a vacation. She earns $10 an hour for babysitting and already has $252 saved for the trip. Which inequality can be used to find the number of hours she needs to babysit

Answers

Answer:

[tex]252 + 10h \ge 575[/tex]

Step-by-step explanation:

Given

[tex]Savings = 252[/tex]

[tex]Target=575[/tex] -- atleast

[tex]Earnings = \$10[/tex] per hour

Required

Represent as an inequality

Suppose that she babysits for h hours, her total earnings would be:

[tex]Total\ Earnings = 10h[/tex]

In inequalities:

At least means [tex]\ge[/tex]

So, when the total earnings is added to her savings, we have:

[tex]Savings + Total\ Earnings \ge Target[/tex]

Substitute values for Savings, Total Earnings and Target

[tex]252 + 10h \ge 575[/tex]
