What is the equation of a line that passes through the points (3, 6) and (8, 4)?

Answers

Answer:

2x + 5y = 36 in standard form

Step-by-step explanation:

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )

~~~~~

(3, 6)

(8, 4)

m = [tex]-\frac{2}{5}[/tex]

y - 6 = [tex]-\frac{2}{5}[/tex] ( x - 3 )

y = [tex]-\frac{2}{5}[/tex] x + [tex]\frac{36}{5}[/tex] in slope-intercept form

2x + 5y = 36 in standard form

Which value of x makes this equation true? 35 + 42 = 12 + x

Answers

Answer:

Step-by-step explanation:

So let's first set up our equation here:

For which values of A, B, and C will AX +BY=C be a vertical line through the point (8,6)
A. A=1, B=0, C=6
B. A=1, B=0, C=8
C. A=0, B=1, C=6
D. A=0, B=1, C=8

Answers

Answer:

B. A = 1, B = 0, C = 8

Step-by-step explanation:

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (8, 6) with x- coordinate 8, thus

x = 8 is the equation of the vertical line

In comparison to

Ax + By = C, then

A = 1, B = 0, C = 8, that is

x + 0 = 8

x = 8 being the required equation

Answers

Answer:

A (-3, 2.5)

Step-by-step explanation:

A rectangular lot is 20 yards longer than it is wide and its area is 2400 square yards. Find the dimensions of the lot

Answers

Answer:

120

Step-by-step explanation:

Divide 2400 by 20 to get your answer! It may be wrong

Answer:

W = 40

L = 60

Step-by-step explanation:

L = 20 + W

L*W = 2400

(20 + W)*W = 2400

W^2 + 20*W - 2400 = 0

(W + 60)*(W - 40) = 0

W = 40 (yards)

L = 20 + W

= 20 + 40 = 60

W = 40

[tex]4x -3 = 11x[/tex]

Answers

The answer is : -3/7

You move the terms so it looks like: 4x = 11x + 3

Then you collect like terms so you should have -7x = 3

After that just divide both sides by -7x and x should equal -3/7

Answer:

[tex]x=-\frac{3}{7}[/tex]

Step-by-step explanation:

[tex]4x-3=11x\\\\4x-3+3=11x+3\\\\4x=11x+3\\\\4x-11x=11x-11x+3\\\\-7x=3\\\\\frac{-7x=3}{-7}\\\\\boxed{x=-\frac{3}{7}}[/tex]
