Answer:

Funcation 2 and Fauncation 1

Step-by-step explanation:

Function 2 has a greater rate of change than function 1. Therefore, options B and D are the correct answers.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Function 1:

With coordinates (0, -2) and (2, 0)

Now, m=(0+2)/(2-0)

m=1

Substitute m=1 and (x, y)=(0, -2) in y=mx+c, we get

-2=c

Substitute m=1 and c=-2 in y=mx+c, we get

y=x-2

Function 2:

With coordinates (-2, 0) and (0, 4)

Here, m=(4-0)/(0+2)

m=2

Substitute m=2 and (x, y)=(-2, 0) in y=mx+c, we get

0=-4+c

c=4

Substitute m=2 and c=4 in y=mx+c, we get

y=2x+4

Therefore, options B and D are the correct answers.

Answer:  220cm

Step-by-step explanation:

Let's make the base of this triangle 'a' which we know is 21cm

While 'a' and 'b' in Pythagorean are interchangeable, 'c' will ALWAYS be the hypotenuse.

That being said, we also know that 'c' is 221cm

Once we plug in the numbers we have been given, our formula looks like this: 21 squared + b squared = 221 squared

Now it's time to square 'a' and 'c'

Our equation is now simplified to: 441 + b squared = 48841

Now, we need to isolate 'b squared' to find it's value. We do this by subtracting 441 from both sides (it needs to be from both sides to keep the equation even)

With 441 subtracted from both sides, our equation is now: b squared = 48400

Our last step is to find the square root of both sides of the equation, because 'b' is the value of the height of the triangle, but right now we have 'b squared' so to turn that into 'b' we have to find the square root of 'b squared', which would give us 'b' (square roots and squares cancel each other out).

We know that whatever we do to one side must also be done to the other, so since we just found the square root of 'b squared', now we need to find the square root of 48400, which is 220.

That would make our equation: b = 220

b = height = 220

Answer:

1. The sum of 4 and x is 7, and to isolate the variable, you move the 4 to the other side and the equation will change into x=7-4, giving us x = 3

2. To solve this inequality, you must isolate the variable x by moving -9 to the other side. To do this, you have to divide 27 by -9, and this causes the direction of the inequality sign to change. After you divide, the inequality changes to this: x<-3

3. since there are no negative numbers involved in this inequality, you divide 3 by 1/4 (or multiply it by 4) to isolate x. this gives us x <= -12

4. To solve this algebraic equation, you must isolate the variable 3x. To do this, you must move -9 to the other side of the equation by adding 9 to the 6. this gives us 3x=15 and x = 5

5. To put x by itself, you subtract 1 by 4, giving you x<-3

Answer:

B.

Step-by-step explanation:

First, (3/2) is greater than 1, which therefore eliminates A and D.

Second, you must determine if the triangle gets larger or smaller. Lets suppose that X = 2 and Y = 3. If we were to multiply both of these values by (3/2), our points would change to X = 3 and Y = 4.5

Since there was an increase, this means that the triangle was larger.

This leaves B as the answer.

Remember: Any scale value greater than 1 is an enlargement, as proven by the hypothetical.

Answer:

The slope is positive, because the line is going up

The equations is.....y = 2/3x - 2

To find slope we can make a table

x      y

6     2

3     0

From 2 to 0, we subtract 2 ( y section)

From 6 to 3, we subtract 3 (x section)

Now we do y/x

so...y/x = -2/-3 = 2/3 (since 2 negatives equal a positive)

Slope = 2/3

And for the y-intercept, I used the graph to help me out, and to find it, you need to see where the line intersects the y-axis which is at -2.

Answer:

Potatoes = $0.56 per pound

Broccoli = $2.90 per pound

Pears = $0.98 per pound

Step-by-step explanation:

Potatoes

To find the price per pound of the potatoes, we will need to divide $2.52 by 4.5 to find out how much one pound costs:

$2.52 / 4.5 = $0.56

The formula is the same for all of the other items.

Broccoli

$7.25 / 2.5 = $2.90

Pears

$2.45 / 2.5 = $0.98

Step-by-step explanation:

I want to give others a chance to earn points as well

You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.

If the salesman sells a car for $a and gets b% of the sale price as commission, then what you need to do is divide the a by 100, then multiply it by b to find out b% of a. This will be the commission that he will earn.

a / 100 x b = commission earned in $

Edit

You've now supplied me with the $ and %, let me explain it again.

To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.

8,100 / 100 = 81

81 x 9 = $729 commission earned.
