Answers

Answer:

x - 4y = 22

Step-by-step explanation:

Given line:

x - 4y = 20

Convert the equation into slope-intercept form:

x - 4y = 20
4y = x - 20
y = 1/4x - 5

It has a slope of 1/4.

Parallel lines have equal slopes.

Find the parallel line lines that passes through the point (2, - 5):

y = 1/4x + b

Substitute x and y values to work out the value of b:

- 5 = 1/4*2 + b
- 5 = 1/2 + b
b = - 5 - 1/2
b = - 11/2

The line is:

y = 1/4x - 11/2

Covert this into standard form:

y = 1/4x - 11/2
4y = x - 22
x - 4y = 22

x-4y=20

Isolate y

$\n \sf\longmapsto x-20=4y$

$\n \sf\longmapsto y=(1)/(4)x-5$

m=1/4
Parallel lines have equal slope

Equation of line in point slope form

$\n \sf\longmapsto y-y_1=m(x-x_1)$

$\n \sf\longmapsto y+5=1/4(x-2)$

$\n \sf\longmapsto 4y+20=x-2$

$\n \sf\longmapsto x-4y+22=0$

Select the correct answer. Martin runs 100 meters in 15 seconds. What is the equation for d, the distance in meters that Martin covers per second? O A. 15+ d = 100 B. 100 + d = 15 O c. dx 15 = 100 D. d x 100 = 15

Answers

Answer:

C) d*15=100

Step-by-step explanation:

The word problem already gives us the product or the end result “Martin runs 100 meters in 15 seconds. So the 100 has to be equal to the expression.

=100

“Per second” this suggests that we should multiply

the most logical answer is d*15=100 or dx15=100
