Answer:

(−2, −8)

Step-by-step explanation:

Write the problem as a mathematical expression.

y = 7x + 6

4x − 3y = 16

Replace all occurrences of y in 4x − 3y = 16 with 7x + 6. 4x − 3 (7x + 6) = 16

y = 7x + 6

Simplify 4x − 3 (7x + 6).

−17x − 18 = 16

y = 7x + 6

Solve for x in the first equation.

Move all terms not containing x to the right side of the equation.

−17x = 34

y = 7x + 6

 Divide each term by −17 and simplify.

x = −2

y = 7x + 6

Replace all occurrences of x with −2 in each equation.

Replace all occurrences of x in y = 7x + 6 with −2. y = 7 (−2) + 6

x = −2

Simplify 7 (−2) + 6.

y = −8

x = −2

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−2, −8)

The result can be shown in multiple forms.

Point Form:

(−2, −8)

Equation Form:

x = −2, y = −8

write and equation of the line parallel to the line  2 x + 4 y = 20 2 x + 4 y = 20 and containing the point  ( −
MAXImum [283]

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m represents the slope of the line

c represents the y intercept

The equation of the given line is

2x + 4y = 20

4y = - 2x + 20

Dividing through by 4, it becomes

y = - x/2 + 5

Comparing with the slope intercept form, slope = - 1/2

If two lines are parallel, it means that they have the same slope. Therefore, the slope of the line passing through (- 6, 3) is - 1/2

To determine the y intercept, we would substitute m = - 1/2, x = - 6 and y = 3 into y = mx + c. It becomes

3 = - 1/2 × - 6 + c

3 = 3 + c

c = 3 - 3 = 0

The equation becomes

y = - x/2

Make a table of values for the equation.<br> y = 3x + 2
Rzqust [24]
Tables are easy to make when u have the equation. Just simply sub any number in for x and solve for y

y = 3x + 2...lets let x = 0
y = 3(0) + 2
y = 2.....so when x = 0, y = 2....(0,2)

y = 3x + 2....lets let x = 1
y = 3(1) + 2
y = 3 + 2
y = 5....so when x = 1, y = 5....(1,5)

y = 3x + 2.....let x = 2
y = 3(2) + 2
y = 6 + 2
y = 8....so when x = 2, y = 8...(2,8)

u can find more point if u need to...

now make a table..

         x            y
        0             2
        1             5
        2             8
and like I said, if u need more numbers for ur table, just do like I did above :)
