A direct variation is a proportional equation. Such as:

For every 3 cookies, linda gets 1 glass of milk. The equation for this is y=3x where y is the glasses and x is the cookies. this is a direct variation. It also has a linear line. Linear means straight. Rate of change and slope are the exact same thing. They are the value of 'm' in y=mx+b

<span>Following BEDMAS

4[3+5(18/2-3)-12]+7^3
</span><span>= 4[3+5(18/-1)-12]+7^3
= </span>4[3+5(-18)-12]+ 343
= 4[3+(-90)-12]+ 343
= 4[3+(-90)-12]+ 343
= 4[-99]+ 343
= -396 + 343
= -53

What is the equation of the line parallel to 3x + 5y = 11 that passes through the point (15, 4)?

soldier1979 [14.2K]

Answer:

The answer is

<h2> $y = - \frac{3}{5} x + 13$ </h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is 3x + 5y = 11

We must first write the equation in the general equation above

So we have

5y = - 3x + 11

Divide both sides by 5

<h3> $y = - \frac{ 3}{5} x + \frac{11}{5}$ </h3>

Comparing with the general equation above

Slope = - 3/5

Since the lines are parallel their slope are also the same

Slope of parallel line = - 3/5

So the equation of the line using point

(15, 4) and slope - 3/5 is

<h3> $y - 4 = - \frac{3}{5} (x - 15) \\y - 4 = - \frac{3}{5} x + 9 \\ y = - \frac{3}{5} x + 9 + 4$ </h3>

We have the final answer as

<h3> $y = - \frac{3}{5} x + 13$ </h3>

Hope this helps you

Write an algebraic expression for the phrase the product of g and 4

Fudgin [204]

Product is the answer to a multiplication problem so we multiply g and 4.

4xg or 4(g). Or even simpler, you could do 4g.

hope it helps!
