Which of these describes the equation 3x + 7y = 8?
Select each correct answer.
A function
B. linear
C. nonlinear
D. proportional
E.
When x is 0, y is
F. When y is 2, x is 2 or -2.

Answers

Answer 1

According to the linear function concept, the correct answer is:

B. linear

Additionally:

When x = 0, [tex]\frac{8}{7}[/tex].When y = 2, x = -2.

What is a linear function?

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.

In this problem, the function is:

[tex]3x + 7y = 8[/tex]

Placing into standard format:

[tex]7y = 8 - 3x[/tex]

[tex]y = \frac{8}{7} - \frac{3x}{7}[/tex]

Hence it is a linear function.

When x = 0:

[tex]y = \frac{8}{7} - \frac{3(0)}{7} = \frac{8}{7}[/tex]

When y = 2:

[tex]y = \frac{8}{7} - \frac{3x}{7}[/tex]

[tex]2 = \frac{8}{7} - \frac{3x}{7}[/tex]

[tex]8 - 3x = 14[/tex]

[tex]3x = -6[/tex]

[tex]x = -\frac{6}{3}[/tex]

[tex]x = -2[/tex]

Step-by-step explanation:

# carry on learning

The solution is, A. y = 5x, the equation represents the relationship between x and y.

What is equation?

An equation can be stated as a  mathematical statement that is made up of two expressions connected by an equal sign.  In its normal form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

Direct proportion equation:

y = kx, where k is the coefficient of proportionality

We have:

x = 3 and y = 15

Using the equation to find the value of k:

15 = 3k

k = 15/3

k = 5

The equation of the line:

y = 5x

Correct choice is A

Hence, The solution is, A. y = 5x, the equation represents the relationship between x and y.

Use the GCF and the distributive property to find the sum of 22+33

Answers

Answer:

22 + 33 = 55 the GCF of 22 and 33 is 11

Step-by-step explanation:

The sum of 22 and 33 by using distributive property will be; 55.

How to find Greatest common factor?

The greatest common factor, as the name implies, is the greatest among all common factors among the quantities given.

We can factorize the quantities in the smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could.

Factors:

22: 1 ,2, 11, 22

33: 1, 3, 11, 33

Both the numbers have a GCF of 11. Then by removing 11 from both numbers you end up with:

22 = 2 x 11

33 = 3 x 11

Now replace the values on the right of the equals sign into the original equation then;

(2 x 11) + ( 3 x 11)

The distributive property allows us to remove the common values and rewrite them;

11(2 + 3)

11(5)

55

The sum of 22 and 33 by using distributive property will be; 55.

What is angle Bi-sector?

In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an item or a form into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.

Given, A triangle in that there is an angle bisector AB.

Since,

Median:

A median of a triangle is a line segment that joins a vertex to the mid-point of the side that is opposite to that vertex.

In our case, it is not specified if AB bisects the opposite line

Altitude:

The altitude of a triangle is the perpendicular drawn from the vertex of the triangle to the opposite side. Also, known as the height of the triangle, the altitude makes a right-angle triangle with the base.

In our case, it is not specified if AB makes a Right triangle or not.

Therefore, Line Ab is neither a Median nor an Altitude.

Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?

Answers

Answer:

$14 9/10

Step-by-step explanation:

Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?

From the above question,

$30 = Gift A + Gift B + Gift C

She spent 9 7/ 10 dollars on gift A and 5 2/5 dollars on gift B.

$30 = $9 7/10 + $5 2/5 + Gift C

Gift C = $30 - ( $9 7/10 + $5 2/5)

Lowest Common Denominator = 10

Gift C = $30 - $14+(7 + 4/10)

Gift C = $30 - $14+(7 + 4/10)

Gift C = $30 - $14+(11/10)

$30 - $14+(1 1/10)

$30 - $15 1/10

Gift C = $14 9/10

Therefore, the amount of money she had left for gift C is $14 9/10

Jim makes $5 an hour at the surf shop. His boss gives him a one-time bonus of $50. Sarah makes $8 an hour at the clothes store. Her boss givers her a one-time bonus of $14. If they both work 15 hours, who will have a bigger paycheck?

Answers

Answer:

Sarah had the bigger paycheck of $134

Step-by-step explanation:

First we would need to find the total amount of money each one of them made in those 15 hours. We do this by multiplying their hourly rate by the hours worked and then adding the bonus

Jim:  (5*15) + 50 = x

          75 + 50 = x

              125 = x

Sarah: (8 * 15) + 14 = x

             120 + 14 = x

                  134 = x

Finally, we can say that Sarah had the bigger paycheck of $134 which is $9 more than Jim's
