What is the slope of the line parallel to 7x + 4y = -16?

Answers

Answer:

The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]

Step-by-step explanation:

Parallel lines have the same slopes and different y-intercepts

The slope of the line who has an equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]

Let us use these rules to solve the question

∵ The equation of a given line is 7x + 4y = -16

→ Compare it with the form of the equation above

∴ a = 7 and b = 4

∵ The slope of the line = [tex]\frac{-a}{b}[/tex]

∴ The slope of the line = [tex]\frac{-7}{4}[/tex]

∵ Parallel lines have the same slope

∴ The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]

Graph the line with slope 1/4 and y intercept -2

Answers

Answer:

y= 1/4x -2

Step-by-step explanation:

Y=mx+b

m is the slope

b is the y intercept

The equation of line is y= 1/4x -2 .

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

slope = 1/4 and y intercept = -2

Using slope- intercept form

y= mx + b

y= 1/4x + (-2)

y= 1/4x -2

What is the answer to this question?

Answers

Answer:

≈ 3.9 miles

Step-by-step explanation:

The third angle in the triangle is

180° - (53 + 78)° = 180° - 131° = 49°

Using the Sine rule in the triangle with distance from 2 being x, then

[tex]\frac{3}{sin49}[/tex] = [tex]\frac{x}{sin78}[/tex] ( cross- multiply )

x × sin49° = 3 × sin78° ( divide both sides by sin49° )

x = [tex]\frac{3sin78}{sin49}[/tex] ≈ 3.9 ( to the nearest tenth )

True or False: X=3 is the solution to 2x+10/5=4.

1. True
2. False

Answers

Answer:

Step-by-step explanation:

False

2x + 10/5 = 4

If the *divided by 5* is for the whole expression
2x + 10 = 20
2x = 20 - 10
2x = 10
x = 10/2 = 5 [false]

If *divided by 5* is only for 10
2x + (10/5) = 4
2x + 2 = 4
2x = 4-2
x = 2/2
x = 1 [false]

Answer will be false in both cases but i gave the solution to make you understand.

Write an expression for the perimeter of the triangle shown below:

A triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15.

4.1x + 29

4.1x − 29

4.5x + 29

4.5x − 29

Answers

4.1x + 29 is the correct answer

Answer:The perimeter is just the sum of all the side lengths.So let's get to work and add it up: (2.3x + 14) + (2x) + (-0.2x + 15)Add up all the x's: (2.3x + 2x - 0.2x) = 4.1xAdd up all the ordinary numbers: (14 + 15) = 29So the perimeter is simply 4.1x + 29.

Mario deposited $6,500 in a simple interest account that pays 2.8% interest annually. If Mario leaves the money in the account for 12 years, how much interest will he earn?

Answers

Answer:

$2,184

Step-by-step explanation:

Simple interest = (Principal × Rate × Time) / 100

Principal = $6,500

Rate = 2.8%

Time = 12 years

Simple interest = (Principal × Rate × Time) / 100

= (6,500 × 2.8 × 12) / 100

= 218,400 / 100

= 2,184

Simple interest = $2,184

The simple interest on $6,500 at 2.8% for 12 years is $2,184
