What is the equation of a line parallel to y=7x-8 that passes through (5, 22)?

Answers

Answer:

y = 7x - 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 7x - 8 ← is in slope- intercept form

with slope m = 7

Parallel lines have equal slopes, thus

y = 7x + c ← is the partial equation

To find c substitute (5, 22) into the partial equation

22 = 35 + c ⇒ c = 22 - 35 = - 13

y = 7x - 13 ← equation of parallel line

What is an equation of the line that passes through the point
(6,7) and is parallel to the line
2x−3y=9?

Answers

Answer:

The equation of line parallel to given line passing through (6,7) is: [tex]y = \frac{2}{3}x+3[/tex]

Step-by-step explanation:

Given equation of line is:

[tex]2x-3y = 9[/tex]

We have to convert the equation in slope-intercept form. The slope-intercept form is given by:

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

Adding 3y on both sides and subtracting 9 from both sides

[tex]2x-3y+3y-9 = 9+3y-9\\2x-9 = 3y\\3y = 2x-9[/tex]

Dividing whole equation by 3

[tex]\frac{3y}{3} = \frac{2x-9}{3}\\y = \frac{2}{3}x - \frac{9}{3}\\y = \frac{2}{3}x-3[/tex]

Let m be the slope of given line then

m = 2/3

Let m1 be the slope of line parallel to given line. Slopes of two parallel lines is equal that means:

m = m1 = 2/3

The equation of line will be:

[tex]y = m_1x +b\\y = \frac{2}{3}x+b[/tex]

Putting the point (6,7) in equation

[tex]7 = \frac{2}{3}(6) +b\\7 = 2(2) +b\\7 = 4+b\\b = 7-4\\b = 3[/tex]

Putting the value of b

[tex]y = \frac{2}{3}x+3[/tex]

Hence,

The equation of line parallel to given line passing through (6,7) is: [tex]y = \frac{2}{3}x+3[/tex]

Hi there! :)

[tex]\large\boxed{y = 2x + 6}[/tex]

A line that is parallel to y = 2x + 3 must have the same slope of 2. Therefore:

We can use the given point as well as the slope-intercept formula y = mx + b to solve.

Plug in the x-coordinate for "x" and y-coordinate of the point into "y":

2 = 2(-2) + b

7x-5=8(x*3) what value of x makes this equation true

Answers

The given equation is:

[tex]\displaystyle 7x-5=8(x+3)[/tex]

The first step you need to do is open the parentheses and distribute the 8 to x+3. It will be 8 times x and 3 times x.

[tex]8(x+3)=8 \times x+ 8 \times 3\\\\8 \times x=8x\\8 \times 3=24[/tex]

[tex]8(x+3) \rightarrow 8x+24[/tex]

Rewrite the equation:

[tex]7x-5=8x+24[/tex]

Now you need to move one of the variables to the other side.

If you move 7x to the other side, then:

You can move the variable by doing the opposite of it. Since 7x is positive, you can move it by subtracting 7x, which is negative. Subtract 7x on both sides:

[tex]7x-5-7x=8x+24-7x\\-5=x+24[/tex]

Now you need to leave x alone. x is being added to 24, so remove it by subtracting both sides by 24. Remember that when you're subtracting from a negative number, you're actually adding while keeping the negative sign.

[tex]-5-24=x+24-24[/tex]

Subtract:

[tex]\bf-29=x[/tex]

If you move 8x to the other side, then:

8x is positive, so you can move it by subtracting 8x, which is negative. Subtract 8x on both sides:

[tex]7x-5-8x=8x+24-8x\\-x-5=24[/tex]

You need to leave the variable alone, so move -5 to the other side. You can do this by adding 5 to both sides.

[tex]-x-5+5=24+5\\-x=29[/tex]

Lastly, x is negative, but you're looking for the value of positive x. Divide both sides by -1 to remove the negative sign.

[tex]\displaystyle \frac{-x}{-1} =\frac{29}{-1}[/tex]

Remember that a positive number divided by a negative number is negative. Divide:

[tex]\bf x=-29[/tex]

The answer to your question is x = -29.

Which point is the y-intercept of the line represented by the equation y-3=13(x+6)?







(0,9)

Answers

Answer:

The equation for a zero slope line is one where the X value may vary but the Y value will always be constant. An equation for a zero slope line will be y = b, where the line's slope is 0 (m = 0).

The y-intercept of the equation will be at (0, 81). Then the correct option is A.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

y - 3 = 13(x + 6)

Convert the linear equation into slope-intercept form. Then the equation is written as,

y - 3 = 13x + 78

y = 13x + 78 + 3

y = 13x + 81

The y-intercept of the equation will be at (0, 81). Then the correct option is A.

Tracy is borrowing $10,700 on a six-year, %, add-on interest loan. What will Tracy's monthly payments be?

Answers

Answer:

Step-by-step explanation:

Use the formula I=prt. (Interest = principle x rate x time)

So, I = 10700 x 0.07 (7% as a decimal) x 6

So, I = 749(6)

I = 4494

Now, divide 4494 by 6(12)

4494/71

This = 63.3 dollars.

Therefore, she is paying 63 dollars per month.

Tracy's monthly payments is $62.41.

What is Simple Interest?

The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more. When you pay back a loan, the monthly interest is deducted first, and any remaining funds are applied to the principle.

Amount (A) = Principal (P) + Interest (I)

and, Simple Interest = PRT/100

Given:

P= 10700

Time= 6 year

Interest = 7%

Now, using simple interest

SI = P x R x T/100

SI = (10700 x 0.07 x 6)

SI = $4494

So, Tracy's yearly payments

= 4494/6

= 749

and, Tracy's monthly payments

= 749 / 12

= 62.41

Hence, Tracy's monthly payments is $62.41.
