Which equation is true?
A) 3 x (5 + 1) = 3+ (5 x 1)
B) 5 x (2+8)= 10 +8
C) 8 x (2+9)= (8 x 2) + (8 x 9)
D) 4+ (2 +9)= (4 + 2) + (4 +9)​

Answers

Answer 1

Answer:

C. 8 x (2 + 9) = (8 x 2) + (8 x 9)

Step-by-step explanation:

Let's solve to see!

Solve using PEMDAS:

Parenthesis

Exponents

Mulitplication/Division (depending on which one comes first - starting from left to right)

Addition/Subtraction (depending on which one comes first - starting from left to right)

A)

3 x (5 + 1) = 3 + (5 x 1) <== parenthesis first

3(6) = 3 + 5 <== multiply and add

18 = 8

False

B)

5 x (2 + 8) = 10 + 8 <== parenthesis first

5(10) = 10 + 8 <== multiply and add

50 = 18

False

C)

8 x (2 + 9) = (8 x 2) + (8 x 9) <== parenthesis first

8(11) = 16 + 72 <== multiply and add

88 = 88

True

D)

4 + (2 + 9) = (4 + 2) + (4 + 9)​ <== parenthesis first

4 + 11 = 6 + 13 <== add

15 = 19

False

Therefore, the correct answer is C.

Answers

Answer:

Step-by-step explanation:

What is circumference?

The circumference of a circle is the distance around the circle, otherwise known as the perimeter.The formula to find the circumference of a circle is 2πr, or if you're given the diameter, πd

How does it apply here?

We are asked to find the closest circumference given of the swimming pool. We are also given the radius of the pool as 7.8 meters.

Solving

Step 1: Plug in your values.

[tex]2 * 3.14 * 7.8[/tex]

Step 2: Simplify.

[tex](2*3.14)*7.8 = 6.28 * 7.8[/tex] [tex]6.28 *7.8 = 48.984[/tex] 48.984 ≈ 48.98

Therefore, the correct answer is F. 48.98 meters.

Answers

f(x) = x² - 2g(x) = 4x + 1

Go from right to left in such function questions

a. f(g(x))

⇒ f(4x + 1)

⇒ (4x + 1)² - 2

⇒ 16x² + 8x + 1 - 2

⇒ 16x² + 8x - 1

b. g(f(x))

⇒ g(x² - 2)

Step-by-step explanation:

Given functions:

In one of these functions, there is a line with a stopping point.

The function y = 3/x + 1 has a point that does not have a value, which is 0. 0 cannot be a value in a denominator. All of the other functions can be expressed at all values.

Which value of x makes the following equation true?

2(x + 10) = x + 23
A.
3
B.
23
C.
13
D.
-7

Answers

Answer:

[tex]\Longrightarrow:\boxed{\sf{x=3}}[/tex]

Step-by-step explanation:

Isolate the term of x, from one side of the equation.

2(x+10)=x+23

Use the distributive property.

Distributive property:

⇒ A(B+C)=AB+AC

2(x+10)

2*x=2x

2*10=20

2x+20=x+23

First, subtract by 20 from both sides.

2x+20-20=x+23-20

Solve.

Subtract the numbers from left to right.

23-20=3

2x=x+3

Then, you subtract by x from both sides.

2x-x=x+3-x

Solve.

[tex]\Longrightarrow: \boxed{\sf{x=3}}[/tex]

Therefore, the correct answer is x=3.

Answer:

x = 3Option A is the correct answer .

Step-by-step explanation:

In this question we're given with an equation that is 2(x + 10) = x + 23 and we are asked to find the value of x .

Solution : -

[tex] \longmapsto \: 2(x + 10) = x + 23[/tex]

Step 1 : Solving the parenthesis on left hand side :

[tex]\longmapsto \:2x + 20 = x + 23[/tex]

Step 2 : Subtracting 20 on both sides :

[tex]\longmapsto \:2x + \bold{ \cancel{20}} - \bold{ \cancel{20} }= x + \bold{23 - 20}[/tex]

On further calculations , we get :

[tex]\longmapsto \:2x =x + 3[/tex]

Step 3 : Subtracting x on both sides :

[tex]\longmapsto \:2x - x = \bold{ \cancel{x} }+ 3 - \bold{ \cancel{x}}[/tex]

On further calculations, we get :

[tex]\longmapsto \: \red {\boxed{{x = 3}}}[/tex]

Therefore, value of x is 3 .

Now , we're verifying our answer by substituting the value of x in given equation :

2(x + 10) = x + 23

2 ( 3 + 10 ) = 3 + 23

2 ( 13 ) = 26

26 = 26

L.H.S = R.H.S

Hence, Verified .

Therefore, our answer is correct.

Answers

The monthly payment for a $5000 loan at a 5.25% rate is 97.25. Then the correct option is B.

What is a monthly payment?

The term loan refers to a sort of credit vehicle in which a sum of money is lent to another party in exchange for the value or principal amount being repaid in the future.

The loan amount is $5000 with a rate of 6.25% over 60 months.

Then the monthly payment (MP) will be

[tex]r = \dfrac{0.0625}{12} = 0.0052[/tex]

Then the formula will be

[tex]\rm MP = P \times \dfrac{r(1+r)^n}{(1+r)^n - 1}\\[/tex]

P = $5000

r = 0.0052

n = 60

Then we have

[tex]\rm MP = P \times \dfrac{0.005208(1+0.005208)^{60}}{(1+0.005208)^{60} - 1}\\\\MP = 97.245 \approx 97.25[/tex]

Step-by-step explanation:

If the slope of a line is 4/5, does the line rise (from left to right), fall (from left to right), horizontal or vertical?

Answers

slope: 4/5 is a positive slope

positive slopes rises from left to rightpositive slopes falls from right to leftneither horizontal or vertical.

The picture below shows some examples of equation with positive slope.

Answer:

rise from left to right

Step-by-step explanation:

Linear equation: [tex]y=mx+b[/tex]

(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)

Positive slope: rise from left to right

[tex]m[/tex] is a positive number

[tex]\textsf{e.g.}\:y=\dfrac45x+4[/tex]

Negative slope: fall from left to right

[tex]m[/tex] is a negative number

[tex]\textsf{e.g.}\:y=-\dfrac45x+4[/tex]

Zero slope: horizontal line

[tex]m=0[/tex]

[tex]\textsf{e.g.}\:y=0x+\dfrac45\implies y=\dfrac45[/tex]

Therefore, a horizontal line is [tex]y = a[/tex] (where [tex]a[/tex] is some constant)

Infinite slope: vertical line

[tex]m= \infty[/tex]

[tex]\sf slope\: (m)=\dfrac{change\:in\:y}{change\:in\:x}[/tex]

There is no change in x-values for a vertical line, so:

[tex]\sf \implies slope=\dfrac{change\:in\:y}{0}=\infty[/tex]

We also usually call the slope of this line undefined.

Therefore, a vertical line is [tex]x = a[/tex] (where [tex]a[/tex] is some constant)
