Answer:

y = -12/11

Step-by-step explanation:

-8y - 13 = 14y + 11

-8y - 14y = 11 + 13

-22y = 24

y = 24/-22

y = -12/11

Check:

-8*-12/11  -  13 = 14*-12/11 + 11

96/11  -  13 = -168/11  +  11

96/11 - 143/11 = -168/11 + 121/11 = -47/11

The absolute value of any positive number is that number itself.

If you take the absolute value of a negative number, then just erase the negative sign and you have your answer.

The absolute value is never negative. It represents distance from that value to 0 on the number line.

So saying |2.3| = 2.3 means the number 2.3 is exactly 2.3 units away from 0 on the number line.

Another example would be |-7| = 7 showing that from 0 to -7 is 7 spaces.

The required absolute number of 2.3 is also 2.3.

GIven that,
An absolute number of the value 2.3 is to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

The absolute number is defined as the outcome of the modulus function is called the absolute number or all natural numbers are examples of absolute numbers.

Here,
For the absolute value,
f(x) = |x|
f(2.3) = |2.3|
(since |x| = x or | -x  | = x )
f( 2.3 ) = 2.3

Thus, the required absolute number of the value 2.3 is 2.3 itself.

Answer:

Mia's test score is 44 if she got 3 questions wrong.

Mia's test score is (50-2x) if she got x questions wrong.

Step-by-step explanation:

It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.

If she got 3 questions wrong, then

Deducted marks [tex]=2\times 3=6[/tex]

Marks obtained by Mia = Total marks - Deducted marks

                                      [tex]=50-6[/tex]

                                     [tex]=44[/tex]

So, Mia's test score is 44 if she got 3 questions wrong.

If she got x questions wrong, then

Deducted marks [tex]=2\times x=2x[/tex]

Marks obtained by Mia = Total marks - Deducted marks

                                      [tex]=50-2x[/tex]

So, Mia's test score is (50-2x) if she got x questions wrong.

Answer:

Mark-up percentage is 25%.

Step-by-step explanation:

From the question, the store bought each sled at $32 which is the cost price. The sled was display for sale at $40 apiece.

Mark-up percentage = [tex]\frac{selling price - cost price}{cost price}[/tex] x 100%

But,

selling price - cost price = $40 - $32

                                        = $8

So that,

Mark-up percentage = [tex]\frac{8}{32}[/tex] x 100%

                                  = 0.25 x 100%

                                  = 25%

Therefore, the mark-up percentage is 25%.

Answer:

square root of 50 estimated to the nearest integer is, 7.1

Step-by-step explanation:

step 1. the square root of 50 is 7.07106781186548

step 2. reduce is 7.07

step 3. round 7.07 so you only have one digit after the decimal point to get the answer., 7.1

Answer:

7

Step-by-step explanation:

Consider perfect squares either side of 50, that is

49 < 50 < 64, thus

[tex]\sqrt{49}[/tex] < [tex]\sqrt{50}[/tex] < [tex]\sqrt{64}[/tex] , that is

7 < [tex]\sqrt{50}[/tex] < 8

Since 50 is nearer to 49 than it is to 64, then

[tex]\sqrt{50}[/tex] ≈ 7 ( to the nearest integer )

Answer:

y(t) = 494 (1.03)^t

y(10) = 663,89

Step-by-step explanation:

An increase in population by 3% each year means that at the end of each year, the population is 1.03 times what it was at the start of the year

This increase in population continues for t years

Exponential growth model that represents the population y (in thousands) t years after the beginning of the decade is

y(t) = 494 (1.03)^t

Where,

y = population

t = number of years

Find y when t = 10

y(t) = 494 (1.03)^t

y(10) = 494 (1.03)^10

= 494 ( 1.3439)

= 663.8866

Approximately y(10) = 663.89

This means that after 10 years from when the population was 494,000, it increased to 663,89.

Step-by-step explanation:

✦ First simplify parts of the equation to make it easier:

  ✧ 2⁵ = 32

  ✧ 3² = 9

✦ Rewrite and solve parenthesis:

  ✧ (32 ÷ 9)⁴ = 3.55555556⁴

✦ Now solve the exponent:

  ✧ 3.55555556⁴ = 159.819541

✦ Simplify your answer:

  ✧ 159.82 (I rounded to the nearest hundredths)

The equation for break even is 8P = 48

An equation is an expression that states the equality of two things expressed in different form.

In the given question

Conard spent $48 for art supplies

Canvas costs $2

He plans to sell his painting for $10

∴ Without the canvas his paintings costs $(10 - 2)

= $8

So, no. of paintings (P) to break even he needs to sell

8P = 48

P = 6

∴ Conard needs to sell 6 paintings to break even.

Answer:

Y=-4x

Step-by-step explanation:

Whenever you solve for slope, and the slope is 1, never write 1 in the equation. Write either -x or x. Let's take two coordinates, one which is (0, 0), which is the origin, and (1, -4). To find the slope, we insert the first coordinate and second coordinate values into the equation (Y2-Y1)/(X2-X1). We can insert these coordinates to get (-4 - 0)/(1 - 0), which simplifies to (-4)/1, which further simplifies to -4. Since the Y-intercept is zero, there is no value of B in the equation, which leaves the equation as Y=-4x

Answer:

Answer:

x=3 I hate asking for things but may  i have brainliest I need to rank up

Step-by-step explanation:

Step 1: Add 4 to both sides.

2/3x−4+4=−2+4

2/3x=2

Step 2: Multiply both sides by 3/2.

(3/2)*(2/3x)=(3/2)*(2)
