Which of the following equations are equivalent? Select three options.
2 + x = 5
x + 1 = 4
9 + x = 6
x + (negative 4) = 7
Negative 5 + x = negative 2

Answer:

Step-by-step explanation:

Answer:

d = 5√2 units

Step-by-step explanation:

Let's use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Plug in the values with your endpoints.

d = √[(-6 - (-7))² + (4 - 11)²]

Solve within the parentheses.

d = √[(1)² + (-7)²]

Solve the exponents.

d = √[1 + 49]

Solve within the brackets.

d = √50

Simplify the square root.

25 • 2 = 50

√25 • √2 = √50

5 • √2 = √50

d = 5√2 units

Hope this helps!

Answer:

71

Step-by-step explanation:

Those are supplementary angles meaning they add up to 180 degrees

180 - 109 = 71

That would make b 71 degrees

Answer:

71 degrees !!

Step-by-step explanation:

Since the angles A and B both are next to each other, they form a linear pair. Since they are a linear pair, they both add up to 180 degrees (same as a straight angle!) So, if A is 109, you would simply subtract that from 180, and you'd get 71 !!

180-109= 71 !!

I hope this helps... have a great day !

Step-by-step explanation:

So, we must find out what the total bill cost is such that we begin by multiplying the price with the tax such that  $25.30(0.08) = $2.024.

Then we add the tax to the price such that

$25.30+2.024 = $27.32

In the case of adding an 18% tip,

So continuing on from the above post, $27.32 is the total after taxes. Then we add an 18% tip which is  

$27.32 (.18) = $4.92..........Then, we add it to the $27.32 to get  

$27.32 + $4.92 = $32.24 in total!

Answer: Down Below

Step-by-step explanation: y=ab%5Ex

that goes through points (0, 10) and (2, 490)

y=ab%5Ex.......plug in (0, 10)

10=ab%5E0

10=a%2A1

a=10

so far

y=10b%5Ex......plug in (2, 490)

490=10b%5E2

b%5E2=490%2F10

b%5E2=49

b=sqrt%2849%29

b=7

your function is:+y=10%2A7%5Ex

A function assigns the values. The exponential function that goes through (0, 13) and (3, 832) is y=13(4)ˣ.

A function assigns the value of each element of one set to the other specific element of another set.

Given the exponential eqation is y=abˣ, substitute any one of the point in equation we will get,

13 = ab⁰

13 = a ₓ 1

a = 13

Therefore, the function can be written as y=13bˣ.

Substitute other point in the equation,

832 = 13 (b³)

b³ = 832/13

b³ = 64

b = 4

Hence, the exponential function that goes through (0, 13) and (3, 832) is y=13(4)ˣ.

Answer:

Step-by-step explanation:

From the given information;

The null hypothesis & alternative hypothesis:

[tex]\mathbf{H_o:\mu = 2} \\ \\ \mathbf{H_1 : \mu \ne 2}[/tex]

The test statistics can be computed as:

[tex]Z = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}}}[/tex]

[tex]Z = \dfrac{2.025- 2}{\dfrac{0.07}{\sqrt{35}}}[/tex]

[tex]Z = \dfrac{0.025}{\dfrac{0.07}{\sqrt{35}}}[/tex]

[tex]Z =2.11[/tex]

The p-value = 2(Z > 2.11)  since this is a two-tailed test

The p-value = 2( 1 - Z < 2.11)

The p-value = 2 (1 -0.9826)

The p-value = 2 (0.0174)

The p-value = 0.0348

Decision Rule: To reject the [tex]\mathbf{H_o}[/tex]  if the p-value is less than [tex]\mathbf{H_o}[/tex]

Conclusion: We fail to reject [tex]\mathbf{H_o}[/tex] and conclude that the population mean = 2, thus the machine is properly adjusted.
