Answer:

B

Step-by-step explanation:

Given

\frac{4}{2} = \frac{3}{x} ( cross- multiply )

4x = 6 ( divide both sides by 4 )

x = 1.5 → B

Answer:

3/2 0r B. 1 1/2

Step-by-step explanation:

Step 1: Cross-multiply.

4/2=3/x

4*x=(3)*(2)

4x=6

Step 2: Divide both sides by 4.

4x/4=6/4

x=3/2

Answer:

x=3/2

3/2 is an equivilant to B 1.5 or 1 1/2

Write the slope-intercept equation of the line parallel to 5y = 2x + 20 that goes through (-1, 3)
katen-ka-za [31]

Answer:

y = \frac{2}{5}x + 3\frac{2}{5}

Step-by-step explanation:

This line was never finished, so you finish it like this:

\frac{5y}{5} = \frac{2x + 20}{5} → y = \frac{2}{5}x + 4

3 = −⅖ + b

3\frac{2}{5} = b \\ \\ y = \frac{2}{5}x + 3\frac{2}{5}

Parallel Lines have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so ⅖ remains the way it is.

I am joyous to assist you anytime.

What is the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4) ?
maxonik [38]
ANSWER

y + 5= - \frac{9}{11} (x-3)

or

y - 4= - \frac{9}{11} (x + 8)

EXPLANATION

We want to find the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4).

The point-slope form is given by;

y-y_1=m(x-x_1)

where

m = \frac{4 - - 5}{ - 8 - 3} = \frac{4 + 5}{ - 11} = - \frac{9}{11}

is the slope of the line.

If

(x_1,y_1)=(3,-5)

The point-slope form is

y + 5= - \frac{9}{11} (x-3)

On the other hand, if
(x_1,y_1)=( - 8,4)

Then the point-slope form is,

y - 4= - \frac{9}{11} (x + 8)

These two equations are the same when simplified.
