-14=-20y-7x 10y+4=2x

1 answer:

7 0

The two given equations are:
-14=-20y-7x and 10y+4=2x

In order to find x and y, we can do it by substitution or by elimination.

By Elimination.
Multiply 10y+4=2x by 2
= 20y + 8 = 4x

Then add it to the second equation
-20y - 7x = -14
20y - 4x = -8
---------------------
-11x = -22
x = 2

Then get y,
10y+4=2x
10y = 2x - 4
10y = 2(2) - 4
y = 0.

So the answer is x = 2, y = 0

Benito has 42 orange juice boxes and 36 grape juice boxes. If Benito gives each friend an equal number of each type of juice box

Mice21 [21]

To find the answer for this question,you need to find the highest common factor for both 42 and 36,and the factors are 1,2,3,and 6. The highest number in that group is 6 so Benito can share the juice boxes to 6 friends.

Lines m and n are parallel. Line m is described by y=4x+2. Line n contains the point (1, -3). Which of the following is an equat

Semmy [17]

The equation of line m, in point-slope form is: y + 3 = 4(x - 1)

Recall:

The slopes of parallel lines are equal to each other.

Slope-intercept form equation is: y = mx + b, where m is slope and b is y-intercept.

Point-slope form equation is: $y - y_1 = m(x - x_1)$ where, $(x_1, y_1)$ is a point and m is the slope.

Equation of line m is y = 4x + 2

Slope of line m is 4

Since line m and line n are parallel, both lines will have the same slope. Therefore, the slope of line n is 4.

To write the equation for line if it contains the point (1, -3), substitute $(x_1, y_1)$ = (1, -3) and m = 4 into $y - y_1 = m(x - x_1)$ :

$y - (-3) = 4(x - 1)\\\\\mathbf{y + 3 = 4(x - 1)}$

Therefore, the equation of line n, in point-slope form is: y + 3 = 4(x - 1)
