is (3,4) a solution to the linear equation y=4x-8? Yes or No?

Answers

Answer 1

Answer:

Yes

Step-by-step explanation:

To find if the point (3,4) a solution to the linear equation y=4x-8 you need to substitute (3,4) into y=4x-8

(x,y)

(3,4)

x=3 and y=4

Subistute:

4=4(3)-8

4=12-8

4=4 which is correct so the answer is yes (3,4) is a solution for y=4x-8

Which function listed below has a greater rate of change
than the one in the graph?

A. f(X)= -0.3x + 2

A slope is also known as the gradient of a line. The listed function that has a greater rate of change than the one in the graph is f(X)= x + 1.

What is Slope?

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The coordinates through which the line of the graph is passing are (0,-4) and (6,0). Thus, the slope of the given line is,

Slope, m = (-4 - 0)/(0 - 6) = -4/-6 = 2/3 = 0.6667

Comparing the given equation with the general equation of a line, y=mx+c, where m is the slope of the line. Therefore, the slope of the given lines is,

A. f(X)= -0.3x + 2

slope = -0.3x

Hence, the slope is less than the slope of the given graph.

B. f(X)= x + 1

slope = 1

Hence, the slope is greater than the slope of the given graph.

C. f(X)= 0.1x + 2

slope = 0.1x

Hence, the slope is less than the slope of the given graph.

D. f(X)= -0.25x - 3

slope = -0.25x

Hence, the slope is less than the slope of the given graph.

Hence, the listed function that has a greater rate of change than the one in the graph is f(X)= x + 1.

type your answer...

Answers

The triangle for this question has been attached.

Answer:

LI = 18

Step-by-step explanation:

From ratio of corresponding sides of a triangle, we know that from the attached image, we can say that;

JK/KH = JL/LI

We are given;

JK = 7

KH = 21

JL = 6

Plugging in relevant values, we have;

7/21 = 6/LI

Making LI the subject, we have;

LI = 21 × 6/7

LI = 18

Given the points (-4, 13) and (6,-2) find the slope in simplest form?

Answers

Sorry i miscalculated this one

Answer:

-3/2

Step-by-step explanation:

(see attached for reference)

the formula for slope is given as :

slope, m = (y₂-y₁) / (x₂-x₁)

in our case , we are given

(x₁,y₁) = (-4, 13)

(x₂, y₂) = (6, -2)

substitute these into the formula above:

m = (y₂-y₁) / (x₂-x₁)

= [-2 - 13] / [6 - (-4) ]

= -15 / 10

= -3/2

Answers

since you are given x then x=5
now you plug in x into the equation which is

which equals to 10+y=10
minus 10 on both sides to get y by itself
y=10-10
y=0

Y=0 y+2(5)=10 y+10=10 minus 10 away on both sides

Find the value of x 3x+6 41 6x-5 4x+7 62 7x-11

Answers

Answer:

Step-by-step explanation:

Simplifying

3x + 6 + 7x + -11 + 41 + 62 + 6x + -5 + 4x + 7 = 360

Reorder the terms:

6 + -11 + 41 + 62 + -5 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: 6 + -11 = -5

-5 + 41 + 62 + -5 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: -5 + 41 = 36

36 + 62 + -5 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: 36 + 62 = 98

98 + -5 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: 98 + -5 = 93

93 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: 93 + 7 = 100

100 + 3x + 7x + 6x + 4x = 360

Combine like terms: 3x + 7x = 10x

100 + 10x + 6x + 4x = 360

Combine like terms: 10x + 6x = 16x

100 + 16x + 4x = 360

Combine like terms: 16x + 4x = 20x

100 + 20x = 360

Solving

100 + 20x = 360

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-100' to each side of the equation.

100 + -100 + 20x = 360 + -100

Combine like terms: 100 + -100 = 0

0 + 20x = 360 + -100

20x = 360 + -100

Combine like terms: 360 + -100 = 260

20x = 260

Divide each side by '20'.

x = 13

Simplifying

x = 13

Mrs. Blue has eight packages of pencils that she wants to distribute evenly between her sixth grades students. There are 24 pencils in each package, and she has 22 students. How many pencils will be left over after Mrs. Blue has given each student the same number of pencils?

Answers

Answer:

Step-by-step explanation:

If there are 22 students and she has 24 pencils she would need to give each of them 1 pencil. 24-22= 2

The number of pencils will be left over after Mrs Blue has given each student the same number of pencils is 16 pencils.

Given that, Mrs Blue has eight packages of pencils that she wants to distribute evenly among her sixth grades students. There are 24 pencils in each package, and she has 22 students.

We need to find out how many pencils will be left over after Mrs Blue has given each student the same number of pencils.

What is the unitary method?

The unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit. It is a method that we use for most of the calculations in math.

There are 24 pencils in each package and there are eight packages of pencils.

So, the total number of pencils=8×24=192

Now, she is distributing evenly among 22 students=192/22=8.72

Then, 8×22=176

Mrs Blue is distributing 8 pencils to each student.

Number of pencils left=192-176=16

Hence, the number of pencils will be left over after Mrs Blue has given each student the same number of pencils is 16 pencils.
