Answer:

600

Step-by-step explanation:

Last years enrollment was 100% of the number.

This year, the enrollment went up by 10%, so now, it's 110% of last years number.

Let last year's enrollment be x.

110% of x is 660

1.1x = 660

x = 660/1.1

x = 600

Step-by-step explanation:

Answer:

25

Step-by-step explanation:

3x - 5 = 2x + 20 ( corresponding angles)

3x - 2x = 20 + 5

x = 25

10.Let's solve for f.

gx=fx−4

Step 1: Flip the equation.

fx−4=gx

Step 2: Add 4 to both sides.

fx−4+4=gx+4

fx=gx+4

Step 3: Divide both sides by x.

fx/x=gx+4/x

The correct answer would be f= gx+4/x

11. Let's solve for f.

hx=12fx+2

Step 1: Flip the equation.

12fx+2=hx

Step 2: Add -2 to both sides.

12fx+2+−2=hx+−2

12fx=hx−2

Step 3: Divide both sides by 12x.

12fx/12x = hx-2/12x

The correct answer would be F= hx-2/12x

12.  Let's solve for f.

kx=(−2f)(−x)

Step 1: Flip the equation.

2fx=kx

Step 2: Divide both sides by 2x

2fx/2x= kx/2x

The correct answer would be F= k/2

Side note: "/" is supposed to represent division and fractions

Answer:

10. f(x) was translated 4 units down

11. f(x) is stretched vertically by a factor of 12 and translated 2 units up

12. f(x) is stretched vertically by a factor of 2, reflected vertically along the x-axis, and reflected horizontally along the y-axis

Step-by-step explanation:

you have to explain what happened to f(x)

start by following the process SRT (stretch, reflection translation) for SR y then x transformations and for T x translation then y translation

Answer: It is constant

Answer:

Constant.

Step-by-step explanation:

Constants are any number that does not have a variable such as x or y, so if they do not have variables, there definitely would not have coefficients. Examples of constants are 2, 5 and 67.

Coefficients are like the 2 in 2x, the 5 in 5y and the 67 in 67xy. All of these numbers have a variable.

Answer:

228

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

1. Translation = (3 - 2, - 4 + 3) = (1, - 1)

2. Reflection over x axis = (3, 4)

3. Reflection over y axis = (-3, - 4)

4. Rotation 90° clockwise = (4, 3)

5. Rotation 180° counter clockwise = (-3, 4)

6. Dialation of 3 = (3*3, - 4*3) = (9, - 12)

Answer:

Answer:

Step-by-step explanation:

Let x be the number of tiles to buy for same cost in both store.

18+0.69 · n = 1.29 · n,

1.29n -0.69n =18 or

0.6n =18

n =18/0.6=30

Therefore, 30 tiles need to buy for same cost in both store.[Ans]

Answer:

I think you need to cross multiply

Answer:

y= -6x-4

Step-by-step explanation:

As two lines are parallel, their slope is same which is -6

Now, use:y-y1=m(x-x1)

y-(-4)= -6(x-0) (y1=-4,x1=0, cause the equation of y axis is x=0)

So,y= -6x-4

Answer:

After 43 minutes, the bacteria will be 40 remainings.

Step-by-step explanation:

Given that:

Initial population of bacteria [tex]A_o[/tex] = 800

After time (t) = 18 mins

A = 240

Using the model:

[tex]A = A_o e^{k*t}[/tex]

[tex]240=800 e^{k*18}[/tex]

[tex]\dfrac{240}{800}= e^{18k}[/tex]

[tex]0.3= e^{18k}[/tex]

By applying natural log on both sides, we get:

In(0,3) = 18k (In e)

- 1.20397 = 18 k * (1)

18 k = -1.20397

k =  -1.20397/ 18

k = - 0.06688

k ≅ -0.07

After time (t), the bacteria population (A) = 40

Now;

[tex]40 = 800 e^{k*t}[/tex]

[tex]\dfrac{40 }{800}= e^{-0.07*t}[/tex]

[tex]0.05= e^{-0.07*t}[/tex]

In (0.05) = -0.07t * In (e)

- 2.9957 = - 0.07t

t = - 2.9957/ -0.07

t = 42.795

t ≅ 43 minutes

Thus, after 43 minutes, the bacteria will be 40 remainings.

Answer:

C.

Step-by-step explanation:

This is because the absolute value of -12 is 12 and the absolute value of -2 is 2. So then the equation would look like this: 12 + 2 = 10, which is a false equation.

Step-by-step explanation:

move all terms to the side that do not contain the variable.

Answer:

Slope (m) = 5

Y-intercept (b) = 3

Step-by-step explanation:

The equation of a line is y = mx + b, where (m) is the slope and(b) is the y-int.

Knowing this, we see that the slope is 5 and the y-int is 3.

Answer:

Yes it is

Step-by-step explanation:

The equation is proportional since as the value of x is increasing, y is also increasing

Equations can either be direct, inverse, or even joint. For instance, if y is directly proportional to x, this is expressed as:

y = kx

k is the variation constant

For a proportional equation, there an increase in a variable will lead to a decrease or increase in other variables

Given the expression y = 9x + 1/2,

when x = 1

y = 9(1) + 1/2

y = 9.5

when x = 2

y = 9(2) + 1/2

y = 18.5

We can see that the equation is proportional since as the value of x is increasing, y is also increasing

Answer:

KL = 40.5

Step-by-step explanation:

From the information given in the diagram, P is the centroid of the triangle. Therefore, applying the centroid theorem,

⅔ of KL = LP

LP = 27

Plug in the value of LP

⅔(KL) = 27

Multiply both sides by 3

2(KL) = 3*27

2(KL) = 81

Divide both sides by 2

KL = 81/2

KL = 40.5
