Given:

The expression is:

[tex]x^2-3x+4+2x^2-x-12[/tex]

To find:

The terms and like terms in the expression.

Solution:

Terms: Variables, constants and product of variable and constants are known as terms which are separated by addition sign "+".

Like terms: The terms which contain same variables with same power are known as like terms.

The given expression is:

[tex]x^2-3x+4+2x^2-x-12[/tex]

It can be rewritten as:

[tex]x^2+(-3x)+4+2x^2+(-x)+(-12)[/tex]

Terms are [tex]x^2,-3x,4,2x^2,-x,-12[/tex].

Like terms are [tex]x^2,2x^2[/tex] and [tex]-3x,-x[/tex] and [tex]4,-12[/tex].

Answer:

g(x + 7) = 11x + 80

g(x) + g(7) = 11x + 83

Step-by-step explanation:

g(x + 7) = 11(x + 7) + 3 = 11x + 77 + 3 = 11x + 80

g(x) + g(7) = 11x + 3 + 11(7) + 3 = 11x + 3 + 77 + 3 = 11x + 83

Answer:

angle wet and angle vet are equal because et bisects wev.

angle wet=angle vet

48°=3x+9

48-9=3x

39=3x

39/3=x

13=x

Answer:

5/3

Step-by-step explanation:

2(4x - 3) + x = 3(2x - 1) + 2

8x - 6 + x = 6x - 3 + 2

9x - 6 = 6x - 1

3x = 5

x = 5/3

Start out by finding the area of the square.

a = 4²

a = 16

Since all we have to look at is 1/4 of this square, multiply the area by 1/4.

(16)1/4

4

The area of the triangle is 4.

Now we need the area of the circle.

a = πr²

Sub: a = π(2)²

a = π(4)

Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.

a = 4 - 1/4(π(4))

a = 4 - 1/4π x 1

a = 4 - 1/4π

Now this is where it's supposed to go, considering the fact that π isn't given a value.

Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.

Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.

Uhh good luck I guess this math test is weird

Answer:

The solution is (-1/2, -2)

Step-by-step explanation:

Given 6f-4g=1,6f-6g=5, write these in columnar form:

6f-4g=1

6f-6g=5

Change all of the signs in the first equation:

-6f + 4g = -1

 6f-6g=5

-------------------

     -2g = 4, and so g = -2

Substituting -2 for g in either equation enables us to find f.  Let's use the first equation:    6f - 4(-2) = 5 yields 6f + 8 = 5, or 6f = -3

Then f = -1/2 and g = -2.  The solution is (-1/2, -2)

The expected value of the spinner landing on pink will be 18.

The anticipated value is an extension of the weighting factor in statistical inference. Informally, the anticipated value is the simple average of a significant number of outcomes of a randomly selected variable that was separately chosen.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

If Kelly spins the spinner 120 times. The table is given below.

Color      Frequency

Pink               6

Purple          12

Yellow          9

Blue             13

Total           40

Then the probability of the pink color will be

p = 6 / 40

p = 0.15

Then the expected value of the spinner landing on pink will be

E(x) = 120 x 0.15

E(x) = 18

The expected value of the spinner landing on pink will be 18.

Answer:

9442 lb

Step-by-step explanation:

First find the volume of the tank.  This being a sphere, the volume is V =(4/3)π·r³.  Here the diameter is 17 ft, so the radius, r, is half that:  8.5 ft.

Then the volume of the sphere is V = (4/3)π·(8.5 ft)³, and half that (the volume of the hemisphere) is (2/3)π·72.25 ft³.

Water weighs 62.4 lb/ft³.  To find the weight of the water in the full tank, multiply the tank volume by this weight density 62.4 lb/ft³:

×

(2/3)π·72.25 ft³ · 62.4 lb/ft³ ≈ 9442 lb

Step-by-step explanation:

Answer:

The maximum number of tickets Susana can buy is 8.

Step-by-step explanation:

From the information provided, you can say that the total amount spent at the carnival would be equal to the price per ticket for the number of tickets purchased which can be expressed as:

c=3x, where:

c is the total amount spent

x is the number of tickets purchased

Now, you can replace c with 24 that is the amount Susana's parents gave her to spend at the carnival and then, solve for x:

24=3x

x=24/3

x=8

According to this, the answer is that the maximum number of tickets Susana can buy is 8.

Answer:

V = (4, 4 )

Step-by-step explanation:

Use the midpoint formula, the equation corresponding coordinates to the coordinates of the midpoint M

let V = (x, y ) , W = (8, 6 ) , then

[tex]\frac{x+8}{2}[/tex] = 6 ( multiply both sides by 2 )

x + 8 = 12 ( subtract 8 from both sides )

x = 4

and

[tex]\frac{y+6}{2}[/tex] = 5 ( multiply both sides by 2 )

y + 6 = 10 ( subtract 6 from both sides )

y = 4

coordinates of V = (4, 4 )
