Solve the questions 7, 8, and 9.

Answer:

12

Step-by-step explanation:

Let's look at the following exponent rule below:

[tex]\frac{x^{a} }{x^{b} } = x^{a-b}[/tex]

We can apply this rule to the problem given to help us find the final answer by taking each exponent and subtracting them. Let's illustrate this below:

[tex]\frac{12^{-4} }{12^{-5} } =12x^{-4-(-5)}[/tex][tex]=12^{-4+5} =12^{1} =12[/tex]

Answer:

1) $1380.00 2) $115.70

Step-by-step explanation:

You divide 1200 by 100 and then you multiply that by the percentage and based on if it is discount - or upcharge +. 1200/100=12 Then 12x15=180 And then 1200+180=1380 And thats how you get your answer. Enjoy <3

Step-by-step explanation:

So we are multiplying 2 by 4 to get 8 large batches of peanuts, so we need to do the same sunflower seeds because the "ratio is the same"

Answer:

4

Step-by-step explanation:

The ratio for a small batch

for peanuts to sunflowers seeds is

2:1

and since a large

has 8 cups of peanuts it can be represented as

8:x

we are solving for x

to get from 2 to 8 we multiplied by 4

so find the x value we multiply 1 by 4

which we get 4 cups of sunflowers eeds

with the new ratio being 8:4

Answer:

The distance between the two cities is 360 miles.

Step-by-step explanation:

Let a equal the airspeed of the plane in still air; and d be the distance between the two cities. Then:

d/a+30=1.5

d=1.5a+45

and

d/a-30=2

d=2a-60

So

2a-60=1.5a+45

.5a=105

a=210

d/210-30=2

d=360

The distance between the two cities is 360 miles.

Answer: The expanded form isn't required. Just make sure that it's possible to send the variable you are solving for to one side, and then solve.

Step-by-step explanation:

combine like terms:

3y-y = 7-3

2y = 4

y = 2

Answer:

you'll need 32 cups!

Step-by-step explanation:

a) Between the two times, Time A and Time B, 12 minutes passed (total time).

b) During this time, Josh drove his car for 10.8 miles (total distance).

c) This means that Josh was driving at an average rate (speed) of 0.9 miles per minute.

The average driving rate refers to the speed at which Josh was driving his car.

The average rate is the quotient between the total distance covered and the total time taken to cover the distance.

The distance, time, and speed formula are Distance = Time x Speed.  

Therefore, Speed = Distance/Time.

Reading on odometer at 9:53 = 52,604.1

Reading on odometer at 10:05 = 52.614.9

Distance covered = 10.8 miles (52.614.9 - 52.604.1)

Difference in time = 12 minutes (10:05 - 9:53)

Average speed = 0.9 miles per minute (10.8/12)

Answer: elimanate, simplify, add or subtract

Step-by-step explanation: you first eliminate your fractions by multiplying all terms by the least common denominator of all fractions.

next you Simplify by combining like terms on each side of the inequality.

then you Add or subtract quantities to obtain the unknown on one side and the numbers on the other.

Answer:

1. Slope = -3.000/2.000 = -1.500

2.  x-intercept = 0/3 = 0.00000

3. y-intercept = 0/2 = 0.00000

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*y-(-3*x)=0

Equation of a Straight Line

1.1     Solve   2y+3x  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2y+3x  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 0/2 so this line "cuts" the y axis at y= 0.00000

 y-intercept = 0/2  =  0.00000  

Calculate the X-Intercept :

When y = 0 the value of x is 0/3 Our line therefore "cuts" the x axis at x= 0.00000

 x-intercept = 0/3  =  0.00000  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -0.000 and for x=2.000, the value of y is -3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -3.000 - -0.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -3.000/2.000 = -1.500  

Geometric figure: Straight Line

 Slope = -3.000/2.000 = -1.500

 x-intercept = 0/3 = 0.00000

 y-intercept = 0/2 = 0.00000
