Use substitution to show that 9+6(10-7x) is equivalent to 69-42x.

Answer:

x = -2, y = -1, z = 4

Step-by-step explanation:

4x + 6y - z=-18

z  = 18  + 4 x  +  6 y

3x +2y - 4z = -24

z  = 6  + (3x)/ 4  +  y /2

- 5x + 3y + 2z = 15

z = 15/2 + (5x)/2 - (3y)/2

18  + 4 x  +  6 y = 6  + (3x)/ 4  +  y /2  = 15/2 + (5x)/2 - (3y)/2

x = -22y/13 - 48/13

4(-22y/13 - 48/13) + 6y - (15/2 + (5(-22y/13 - 48/13))/2 - (3y)/2) = -18

Compute the output value of the variables x and y with respect to the input values of x, y, and z coefficients.

Answer:

the slope is 1/2

Step-by-step explanation:

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.

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.

4x4 then dived by 8you will get 4x4=16 dived by 8=8

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

9 3/4 (simplest form)

✨Step-by-step explanation:✨

1. Convert decimal into fraction:

9.75 = 975/100

2. Simplify:

975/100 = 39/4 = 9 3/4

A. Reduce fraction to lowest terms (25 is the greatest common divisor of 975 and 100. Reduce by dividing both numerator and denominator by 25):

975/100 = 975 ÷ 25   = 39/4

                 100 ÷ 25

B. Convert improper fraction to mixed number:

39/4 = 9 3/4

(39 ÷ 4 = 9 remainder 3)

How long did it take her to save 200? 5

How much did priya have in her savings account when she started to save regularly? 80

Answer: 600 sheets

Step-by-step explanation:

300/1 -> 300 sheets per 1 hour

To find the number in two hours, multiply the numerator and the denominator by 2.

300 x 2 = 600

1 x 2 = 2

Thus, the factor makes 600 sheets in 2 hours.

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.

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.

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]
