Write an explicit formula for an, the n^th term of the sequence 22, 20, 18, ....

170 ..I think I'm correct

Answer:

m∡P = 40°

Step-by-step explanation:

15m + 17 + 4m - 10 + 7m - 9 = 180

26m - 2 = 180

26m = 182

m = 7

∡P = 7(7) - 9 = 49 - 9 = 40

Answer:

56x+21

Step-by-step explanation:

7times 8x is 56x

7 times 3 is 21

add them together and you get 56x+21

Answer:

The correct options are:

A, B, and E.

Step-by-step explanation:

A mathematical sentence (or a mathematical statement) is a sentence that can be true or false.

This is the only criteria we need to check, now let's analyze each option.

A: 4 - d = 12

This can be true or false, for example, if d = 0 the sentence is false because:

4 - 0 = 12

4 = 12 is false.

and if d = -8 the sentence is true, because:

4 - (-8) = 12

4 + 8 = 12

12 = 12

is true.

B: 4 - V > 2

This sentence can be true or false, same reasoning as before, we can find values of V such that this is true or false.

C: 3 + 2

Now, here we can't say if this is true or false, so this is not a mathematical sentence.

D: 59

Same as before, this is just a number.

E: 6 + a = 13

This can be true or false, depending on the value of a, then this is a mathematical sentence.

F: 12*x

Here we can not say if this is true or false, so this is not a mathematical sentence.

The correct options are:

A, B, and E.

Answer:

x=8

Step-by-step explanation:

-2(8) would be -16 so -18 is still greater

Answer:

B

Step-by-step explanation:

all the others will have a value of more than -18. Only B makes sense.

Answer:

78

Step-by-step explanation:

Arc GHJ is 81*2= 162 (the arc measure of an inscribed angle that does not cross the center of the circle is 2 times the measure of the angle

since arc GH is 84 and we need HJ, subtract 84 from 162=78

20 + 5 = 25

5 is a fifth of 25

Answer:

[tex]\frac{1}{5}[/tex]

Step-by-step explanation:

There are 25 socks in total, only 5 of these are green.

The proportion would look like this:

Answer:

8y + 96

Step-by-step explanation:

it's (8 x y) + (8 × 12)

Answer:

x = 7 hope this helps !!!

Step-by-step explanation:

Type 1: You know the short leg (the side across from the 30-degree angle). Double its length to find the hypotenuse. You can multiply the short side by the square root of 3 to find the long leg.

Type 2: You know the hypotenuse. Divide the hypotenuse by 2 to find the short side. Multiply this answer by the square root of 3 to find the long leg.

Type 3: You know the long leg (the side across from the 60-degree angle). Divide this side by the square root of 3 to find the short side. Double that figure to find the hypotenuse.

this is a type 3 triangle, and you can find the length of y from it, it being 14, and x is half of y, being 7

Tan (30) = x/7[tex]\sqrt{3}[/tex]

Tan (30) times [tex]7\sqrt{3}[/tex] = x

7 = x

x + 2 + 12

Step-by-step explanation:

Answer:

B.33

Step-by-step explanation:

Plug in 2 for x

(2)^3+6(2)^2+3(2)-5=

Answer:

B

Step-by-step explanation:

Remark

F(2) means that wherever you see an x on the right side of the equal sign, you substitute 2 for.

Suppose the question was f(2) = 3x + 5

Put a 2 where the x is.

f(2) = 3*2 + 5

f(2) = 6 + 5

f(2) = 11

Equation

f(x) = x3 + 6x2 + 3x -5.

Solution

f(2) = 2^3 + 6*2^2 + 3*2 - 5

f(2) =  8 + 6*4 + 6 - 5

f(2) = 8 + 24 + 1

f(2) = 33

Answer:

[tex]f(3) = -16[/tex]

Step-by-step explanation:

Given

[tex]f(x)= - 4x-4[/tex]

[tex]g(x)= 4x^2 + 4x + 2[/tex]

[tex]h(x)= 3x^2 - 3[/tex]

Required

[tex]f(3)[/tex]

We have:

[tex]f(x)= - 4x-4[/tex]

Substitute [tex]x = 3[/tex]

[tex]f(3) = -4 * 3 - 4[/tex]

[tex]f(3) = -12 - 4[/tex]

[tex]f(3) = -16[/tex]

Hence:

[tex]f(3) = -16[/tex]

Answer:

Slope (m) = 2

Step-by-step explanation:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

consider 2 points - (20,20) and (30,40)

[tex]m = \frac{40-20}{30-20}[/tex]

[tex]m=\frac{20}{10}[/tex]

[tex]m=2\\[/tex]

∴ Slope (m) = 2
