Answer:

$3^{14}$ or 4,782,969

Step-by-step explanation:

Note that the base are the same (3). In this case, when you are multiplying, add the powers together:

$3^9 * 3^5 = 3^{9 + 5} = 3^{14}$ .

Write the equation of the line passing through (-3, 4) and normal to -2x + 7y = -3. (Note: normal means perpendicular)

MArishka [77]

Answer:

The answer to your question is y = -7/2x -13/2

Step-by-step explanation:

Point = (-3, 4)

Line -2x + 7y = -3

Process

1.- Solve equation for y to find the slope of the perpendicular line

7y = 2x - 3

y = 2/7 x - 3/7

slope = 2/7

Slope of the perpendicular line = -7/2

2.- Find the equation of the new line

y - y1 = m(x - x1)

y - 4 = -7/2(x + 3)

y - 4 = -7/2x - 21/2

y = -7/2x - 21/2 + 4

y = -7/2x -21/2 + 8/2

3.- Result

y = -7/2x -13/2

If one gallon is the same amount as 4 quarts, how many quarts are in 5 gallons?

wlad13 [49]

If one gallon = 4 quarts
Then 5 gallons = x quarts

To solve this we can set up a porportion

1/4 = 5/x

To solve the porportion we need to find the rule so how to we get to 4 from 1? Well we can multiply 1 by 4 to get one right?

So if this is true, 1 x 4 = 4 then 5 x 4 must equal x

5 x 4 = 20 so the answer would be 20 quarts are in 5 gallons

Another way to look at this is that you have 5 gallons and in each gallon is 4 quarts to if there is 4 quarts in every one gallon then that’s just 4 + 4 + 4 + 4 + 4 or 5 x 4

I hope this helps! <3
