Solve for x and then find the measure of angle, B

Answers

Answer:

x = 11, ∠ B = 80°

Step-by-step explanation:

∠ A and ∠ B are corresponding angles and are congruent, thus

8x - 8 = 5x + 25 ( subtract 5x from both sides )

3x - 8 = 25 ( add 8 to both sides )

3x = 33 ( divide both sides by 3 )

x = 11

Thus

∠ B = 5x + 25 = 5(11) + 25 = 55 + 25 = 80°

A is B are congruent so you do
8x-8=5x+25 which equals x=11 and B=80 because you do 5 times 11 plus 25
Answer:
X=11
B=80

which function does not have a vertical asymptote?

a. y=5x/x*x^2

b. y=5x/1+2x^2

c. y=5x-1/x

d. y=x/1-x^2

Answers

Answer:

B. y=(5x)/(1 + 2x^2)

Step-by-step explanation:

A. y = (5x)/(x * x^2)

Vertical Asymptotes: x = 0

B. y = (5x)/(1 + 2x^2)

Vertical Asymptotes: None

C. y = (5x - 1)/x

Vertical Asymptotes: x = 0

D. y = x/(1 - x^2)

Vertical Asymptotes: x = -1, 1

evaluate the function at each specified
value of the independent variable and simplify

Answers

Answer:

Evaluating the function is just replacing the "x" (or the "t" in the second case) by the value that we want:

1) q(x) = 1/(x^2 - 9)

 a) q(0) = 1/(0^2 - 9) = 1/(-9) = - 1/9

 b) q(3) = 1/(3^2 - 9) = 1/(9 - 9) = 1/0 = indetermined, we could think this as:

  [tex]\lim_{x \to \ 3} q(x) = infinity[/tex]

 c) q(y + 3) = 1/( (y + 3)^2 - 9) = 1/(y^2 + 6*y + 9 - 9) = 1/(y^2 + 6*y)

2) q(t) = (2*t^2 + 3)/t^2

 a) q(2) =  (2*2^2 + 3)/2^2 = (2*4 + 3)/4 = 11/4

 b) q(0) = (2*0^2 + 3)/0^2 = 3/0

  Again, we can not divide by zero, this is simmilar to the case 1.b

 c) q(-x) = (2*(-x)^2 + 3)/(-x)^2 = (2*x^2 + 3)/x^2

Step-by-step explanation:E

The addition property of equality property is used to justify Carmen's first step. Then the correct option is C.

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given below.

3x - 1 = - 1

Add 1 on both sides, then we have

3x - 1 + 1 = - 1 + 1

3x = 0

The addition property of equality property is used to justify Carmen's first step. Then the correct option is C.

Identify the variable(s), set up your equation(s), and solve. Richard has an elder sister who is twice his age and a younger sister who is two years younger than him. If the product of his sisters' ages is 70, how old is Richard?

Answers

Answer:

7 years

Step-by-step explanation:

Given that:

Let Richard's age = x

Elder sister's age = 2x

Youngwr sister's age = x - 2

Product of sisters ages = 70

2x * (x - 2) = 70

2x² - 4x = 70

2x² - 4x - 70 = 0

x² - 2x - 35 = 0

x² - 7x + 5x - 35 = 0

x(x - 7) +5(x - 7) = 0

(x - 7) or (x + 5) = 0

x = 7 or x = - 5

X can't be negative

Hence, x = 7

Richard is 7 years

A triangle has sides with lengths of 11 mm 14 mm and 19 mm is it a right triangle?

Answers

Answer:

no

Step-by-step explanation:

because 2 of the sides would be the same length or almost the same number

Answer:

Not a right triangle

Step-by-step explanation:

I think the question is asking if this a right triangle?

In order to be a right triangle, the side lengths will need to follow Pythagorean theorem which says the two side legs of the triangle squared is equal to the hypothenuse squared or

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]; we can use the length given such as 11mm, 14mm and 19mm (assume is the hypothenuse)

[tex]11^{2}[/tex] + [tex]14^{2}[/tex] =? [tex]19^{2}[/tex]

121 +  196 =? 361

317 ≠ 361; therefore it is not a right triangle

Answer:

$16.00

Step-by-step explanation:

6 wood chairs are 444 which is 74.00 a piece

8 metal chairs are 720 which is 90.00 a piece

90-74= 16

The metal chairs are $16.00 more

If Abigail is buying new chairs to upgrade her restaurant. A set of 6 wooden chairs costs $444. A set of 8 metal chairs costs $720. Then the metal chairs are $16.00 more

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,
