5x−4 = 3x +8
i need the steps on how to find x
plz, i got a 0 the first time i did it

Answer:

(5, 8)

Step-by-step explanation:

Convert the f(x) = to a y =

f(x) = | x - 6 | + 7

y = | x - 6 | + 7

Plug in the values and prove

y = | x - 6 | + 7

(5,8)

8 = | 5 - 6 | + 7

8 = | -1 | + 7

8 = 1 + 7

8 = 8; true

(8,10)

10 = | 8 - 6 | + 7

10 = | 2 | + 7

10 = 2 + 7

10 = 9; false

(6, 9)

9 = | 6 - 6 | + 7

9 = | 0 | + 7

9 = 0 + 7

9 = 7; false

(3, 11)

11 = | 3 - 6 | + 7

11 = | -3 | + 7

11 = 3 + 7

11 = 10; false

(4, 12)

12 = | 4 - 6 | + 7

12 = | -2 | + 7

12 = 2 + 7

12 = 9; false

Therefore the only one which falls on the graph is (5, 8)

Answer:

3.5 divided by 100

Step-by-step explanation:

So we know that one millimeter is equal to 0.01

To solve the equation you would multiply 3.5 x .01 = .035

Another way would be if you divide 3.5/100 = .035

Hope that helps and have a great day!

ARM for which interest will stay fixed for 8 years and then be adjusted every year after that = 8/1 ARM

The correct option is (B).

The term adjustable-rate mortgage (ARM) refers to a home loan with a variable interest rate. With an ARM, the initial interest rate is fixed for a period of time. After that, the interest rate applied on the outstanding balance resets periodically, at yearly or even monthly intervals.

Given statement

ARM for which Interest rate stay fixed for 8 years and then be adjusted every year after that.

Above information is typically expressed in two numbers. The first number indicates the length of time that the fixed rate is applied to the loan, while the second refers to the duration or adjustment frequency of the variable rate.

By the above method ARM for Interest rate stay fixed for 8 years and then adjusted every year after that can be expressed as 8/1 ARM.

Hence, for 8/1 ARM, interest rate will stay fixed for 8 years and then

be adjusted every year after that.

Answer:

x=9

Step-by-step explanation:

Distribute:

3x+9-2x+2=5x-25

Combine like terms:

x+11=5x-25

Solve:

x-x+11=5x-x-25

11=4x-25

11+25=4x-25+25

36=4x

Divide by 9:

x=9.

Hope this helps :D

Answer:

x = 9

Step-by-step explanation:

Step 1: Solve both sides by distributing the values.

3x+9-2x+2 = 5x-25

Step 2: Put the like terms together.

3x-2x-5x = -25-9-2

-4x = -36

Step 3: Divide both sides by -4 to get the value of x.

[tex]\frac{-4x}{-4}[/tex] = [tex]\frac{-36}{-4}[/tex]

x = 9

Let's verify the answer.

3x+9-2x+2 = 5x-25

3(9)+9-2(9)+2 = 5(9)-25

27+9-18+2=45-25

H0 : μ = 215

H1 : μ > 215

Rejection region :

Zstatistic > Z0.05

Step-by-step explanation:

Given that:

Average price of all mobile phones was £215

Sample size = 200

Significance level (α) = 0.05

To determine if the average price of all mobile phones is now greater than £215

The Null hypothesis (H0) :

H0 : μ = 215

Alternative hypothesis (H1) :

H1 : μ > 215

The rejection region :

|Zstatistic > Zα|

α = 0.05 ; Z0.05

Rejection region :

[tex]Area = 9j[/tex]

Step-by-step explanation:

Given

[tex]Base = 9\ units[/tex]

[tex]Height = j\ units[/tex]

Required

Determine the area

Area of parallelogram is calculated as thus:

[tex]Area = base * Height[/tex]

Substitute values for Base and Height

[tex]Area = 9 * j[/tex]

[tex]Area = 9j[/tex]

Hence, the area of the parallelogram whose base is 9 units and height is j units, is 9j

The value of z-score such that 0.02 of the area lies to the right of z would be 2.06.

Given that,

0.02 of the area lies to the right of z.

Now, for the value of z such that 0.02 lies to the right of z, we can make use of the standard normal distribution table.

Since to determine the value of z such that 0.02 of the area lies to the right, we need to find the z-score associated with the cumulative probability of (1 - 0.02) = 0.98

Now for the value of 0.98 in the standard normal distribution table, we find that the corresponding z-score is 2.06.

Therefore, the value of z, rounded to two decimal places, is 2.06.

The value of z such that 0.02 of the area lies to the right of z is approximately 2.05 (rounded to two decimal places).

To find the value of z such that 0.02 of the area lies to the right of z, we need to determine the z-score associated with that probability.

Since we're looking for the area to the right of z, we can use the standard normal distribution table or a statistical calculator to find the corresponding z-score.

By searching the table or using a calculator, we can find that the z-score associated with a right-tail probability of 0.02 is approximately 2.05.

Answer:

k = 0.2

A = (M / P₀) − 1

Step-by-step explanation:

dP/dt = kP

When t = 0, P = 1000 and dP/dt = 200.

200 = 1000k

k = 0.2

P = M / (1 + Ae⁻ᵏᵗ)

When t = 0, P = P₀.

P₀ = M / (1 + A)

1 + A = M / P₀

A = (M / P₀) − 1

[tex]\boxed {d = 15}[/tex]

Step-by-step explanation:

Use the Distance Formula to help determine the distance between two given points:

[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]

First point: [tex](x_{1}, y_{1})[/tex]

Second point: [tex](x_{2}, y_{2})[/tex]

-Substitute both given points:

[tex](x_{1}, y_{1}) = (6, 4)[/tex]

[tex](x_{2}, y_{2}) = (-6, -5)[/tex]

[tex]d = \sqrt{(-6 - 6)^{2} + (-5 - 4)^{2}}[/tex]

-Solve for the distance:

[tex]d = \sqrt{(-6 - 6)^{2} + (-5 - 4)^{2}}[/tex]

[tex]d = \sqrt{(-12)^{2} + (-9)^{2}}[/tex]

[tex]d = \sqrt{144 + 81}[/tex]

[tex]d = \sqrt{225}[/tex]

[tex]\boxed {d = 15}[/tex]

Therefore, the distance is [tex]15[/tex].
