3y+7=31

3y=24 (we subtracted 7 from both sides)

24 divided by 3 is 8

Y=8

By what number should we multiply -3÷4so that the product will be -7÷8⛄
Makovka662 [10]
Let the number be x.

-(3/4)*x = -(7/8)

x = -(7/8)/-(3/4)

x = 7/8 * 4/3

x = 7/6

The number = 7/6

The distance between the parallel lines x – 2y = 3 and 2x – 4y = 12 is
Svetradugi [14.3K]

Given :

Parallel lines are

x – 2y = 3 and 2x – 4y = 12

Step-by-step explanation:

Lets write the given lines in slope intercept form y=mx+b

x -2y = 3  \\-2y=-x+3\\Divide \; both \; sides \; by -2\\y=\frac{x}{2} -\frac{3}{2}

From the above equation , y intercept of first line is \frac{-3}{2}

Solve the second equation for y and find out y intercept

2x-4y=12\\-4y=-2x+12\\Divide \; by \; -4\\y=\frac{1}{2} x-3

y intercept of second line is -3

To find the distance between parallel lines, we subtract the y intercepts

\frac{-3}{2} -(-3)=\frac{-3}{2} +\frac{6}{2} =\frac{3}{2} =1.5

Answer:

The distance between the parallel lines = 1.5

What is the equation of the line that is parallel to y=4/7x-3 and passed through (14,4)?
lesantik [10]

Answer:

see explanation

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 = \frac{4}{7} x - 3 is in this form

with slope m = \frac{4}{7}

• Parallel lines have equal slopes, hence

y = \frac{4}{7} x + c ← is the partial equation

To find c substitute (14, 4) into the partial equation

4 = 8 + c ⇒ c = 4 - 8 = - 4

y = \frac{4}{7} x - 4 ← equation of parallel line
