(the amount should be less than or equal to 125) 125(the amount that the teacher can spend)

Answer:

A.

Step-by-step explanation:

x is what is representing the unknown number. So, both are multiplying x (the unknown number) by 7 and 5, respectively, and adding that number by 32 and 92, respectively.

Answer:  B) The value of k must be between 1 and 2

The function f(x) has a restricted domain [1, 2] which means [tex]1 \le x \le 2[/tex]

So we can only pick inputs in that interval. If x = k, then [tex]1 \le k \le 2[/tex]

Answer:

A

Step-by-step explanation:

Answer:  Slope = 0.667/2.000 = 0.333

 x-intercept = -15/1 = -15.00000

Step-by-step explanation: 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  x-3y+15  = 0 and calculate its properties

Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000

 y-intercept = 15/3  =  5

When y = 0 the value of x is -15/1 Our line therefore "cuts" the x axis at x=-15.00000

 x-intercept = -15/1  = -15.00000

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 5.000 and for x=2.000, the value of y is 5.667. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.667 - 5.000 = 0.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  0.667/2.000 =  0.333

 Slope = 0.667/2.000 = 0.333

 x-intercept = -15/1 = -15.00000

Answer:

Hi there!

Your answer is

y= -2/5x

Step-by-step explanation:

The coefficient of x is the slope. IF the y intercept was something other than the origin, that number would be added. Since it has a y int of (0,0), it is simply the equation above!

Answer:

$325

Mae Ling earns a weekly salary of $325 plus a 6.5% commission on sales at a gift shop. How much would she make in a work week if she sold $4,800 worth of merchandise?

Easy

[tex] \frac{11}{25} \times 100 = \frac{11}{25} \times 25 \times 4 \\ [/tex]

[tex] = 11 \times 4 = 44 \: \: percent[/tex]

So %44 of your class students chose pizza.

The percentage of the class chose pizza = 44%

"It is a number or ratio that can be expressed as a fraction of 100."

For given example,

Total number of students = 25

the number of students who chose pizza as their favorite food = 11

So, the percentage of the class chose pizza would be,

⇒ (11/25) × 100 = 44%

Answer:

20:1

Step-by-step explanation:

It is given that,

Input voltage = 260 volt

Output voltage = 13 volt

We need to find the ratio of the number of input wire coils to output wire coils on the transformer.​

For a step-down transformer,

[tex]\dfrac{V_i}{V_o}=\dfrac{N_P}{N_S}\\\\\dfrac{N_P}{N_S}=\dfrac{260}{13}\\\\=\dfrac{20}{1}[/tex]

Hence, the required ratio is 20:1.

Step-by-step explanation:

Here is Slope-Intercept Form for a line: y=mx+b

m is the slope

b is the y intercept

The y intercept is basically the point on the y axis where the line touches.

I will do #3 for you.

Let's first look for the y intercept. We can see that the line touches the y axis at -4, so that's it.

Let's put it into our equation, plugging in -4 for b. This is what we have so far: y=mx-4

To complete this equation, we still need to find the slope, m.

To find it, look at the point where the y intercept is, and count how many units you need to go up or down the y axis, and then right or left the x axis to get to another point on the line. The slope is equal to the change in y ÷ the change in x.

So we see that there's another point on (-3, -2), so let's try to get there from the y intercept.

We need to move two units up and 3 to the left.

In terms of y, we went up +2, and in terms of x, we went down -3

So our slope is 2/-3 or -2/3.

Now that we have our slope (m) and y intercept (b), we can plug it into out Slope-Intercept Equation, plugging in -2/3 for m:

y=-2/3x-4.

We don't need to find x or y. This is our answer for 3. Using the same method, you should be able to find the equations for the rest of the graphs. Good luck.

Answer:

a = 14°

b = 36°

Step-by-step explanation:

4b - 12 + 48 = 180 (supplementary)

Rearrange

4b = 180 - 48 + 12

4b = 144

b = 36°

4a - 8 + 4b - 12 = 180 (supplementary)

sub b = 36 into equation

4a - 8 + 144 - 12 = 180

Rearrange

4a = 180 - 144 + 12 + 8

4a = 56

a = 14°

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

For this situation we will use this equation:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

This lets us find the slope from a set of points (m being the slope of course), with each one representing a coordinate from our set. (e.g. 7 could be [tex]y_{2}[/tex])

First let's define which coordinates will represent each:

(-1,3): [tex]x_{1} ,y_{1}[/tex]

(5,7): [tex]x_{2} ,y_{2}[/tex]

Now that we have this, we can fill in our coordinates: [tex]m = \frac{7-3}{5-(-1)}[/tex]

Next we simplify: [tex]m = \frac{4}{5+1}[/tex] (double negative = positive)

And simplify some more: [tex]m = \frac{4}{6}[/tex]

Finally, we find the GCF (greatest common factor) of 4 and 6, which is 2, and divide by that to further simplify the fraction: [tex]m = \frac{2}{3}[/tex]

Therefore, the slope of the line that passes through the points (-1,3) and (5,7) is [tex]\frac{2}{3}[/tex].

Answer: f (-2) 5

Your welcome

A function is a relation between two variables where one variable is the set of inputs that gives the other variables as output.

The value of the function at x = -2 is 5.

The domain of the function = 5.

The range of the function = -2.

A function is a relation between a set of inputs called domains and it has one output called the range.

Example:

f(x) = x + 2

At x = 2,

f(2) = 2 + 2 = 4

Domain = 2

Range = 4

We have,

f(x) = x² + 4x + 9

We need to find the value of the function at x = -2.

Substitute x = -2 in f(x).

f (-2) = (-2)² + 4x(-2) + 9

f (-2) = 4 - 8 + 9

f (-2) = 5

Thus the value of the function at x = -2 is 5.
