Answer:

  y = -2·(1/2)^x

Step-by-step explanation:

The general form of the equation can be written as ...

  y = a·b^x

where 'a' is the value of the y-intercept, and 'b' is the ratio of y-values for x-values that differ by 1.

From your table and graph, a = -2. From the table, ...

  b = -1/-2 = 1/2

Then the exponential equation is ...

  y = -2·(1/2)^x

Answer:

Step-by-step explanation:

48+48=96

32+32+32=96

24+24+24+24=96

12+12+12+12+12+12+12+12=96

6+6+6+6+6+6+6+6+6+6+6+6+6+6+6+6=96

I'm not going to write out the rest of the numbers. I'll multiply them.

4 x 24=96  (etc. 4+4+4....)

3 x 32=96  (etc. 3+3+3....)

2 x 48=96  (etc. 2+2+2....)

1 x 96=96   (etc. 1+1+1....)

I hope this is what you meant. If you liked, mark me Brainliest please.

The number 96 is divided into equal groups, then the number of 10 ways is shown below.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

48 + 48 = 96

32 + 32 + 32 = 96

24 + 24 + 24 + 24 = 96

12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 96

6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 = 96

And the rest are written in the form of multiplication. Then we have

4 x 24 = 96  (etc. 4 + 4 + 4 ....)

3 x 32 = 96  (etc. 3 + 3 + 3 ....)

2 x 48 = 96  (etc. 2 + 2 + 2 ....)

1 x 96 = 96   (etc. 1 + 1 + 1 ....)

Answer: The project is 7/8 painted.

Step-by-step explanation: Add 1/8 to 3/4 for the total.

Use the least common denominator, /8

3/4 is equivalent to 6/8.

6/8 + 1/8 = 7/8

Step-by-step explanation: To find how much of the wall Maya painted, we will add the two fractions. Let's do it step-by-step.

1. These fractions have unlike denominators, to make them alike, we have to find the LCD (Least Common Denominator).

3/4 = 6/8

1/8 = 1/8

Note: What you did to the bottom, you do to the top.

1a. I multiplied 2 by 3 and 4 to get 6/8.

1b. I multiplied 1 by 1 and 8 to get 1/8.

2. Since we have like denominators, we can add!

[tex]Solve:\frac{6}{8} +\frac{1}{8} = \frac{7}{8}[/tex]

Therefore, your answer is 7/8. The fraction don't need to be reduced to lowest terms.

Answer:

Step-by-step explanation:

1 foot = 12 inches

47.5 inches × (1 foot)/(12 inches) = (47.5/12) feet

24 boards × ((47.5/12) feet)/board = 95 feet

:::::

(8 feet)/board × (12 inches)/foot = (96 inches)/board

96/47.5 = 2 remainder 1

An 8-foot board provides two 47.5" boards, with an inch wasted.

He needs to buy 12 of the 8-foot boards.

Answer:

x= -4

Step-by-step explanation:

Answer: x = -4

Step-by-step explanation:

first, we remove the parentheses.

3x - 12 + 2x = 7x + 10 + 2x - 6

then, we cancel equal terms.

3x - 12 = 7x + 10 - 6

then, we calculate.

3x - 12 = 7x + 4

next, we move the terms.

3x - 7x = 4 + 12

then, we collect like terms and calculate.

-4x = 16

finally, we divide both sides.

x = -4

Step-by-step explanation:

Wendy has purchased condominium and is financing it through the loan. The loan term is for 8 years with an interest rate of 5.65%. The payment at the start of the year 1 is $595,000 * 5.65% = $3344.70. The loan term reached maturity so the payment will increase to 4143.50

Answer:

$549

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 3050 × 0.06 × 3 = 549

I = $ 549.00

The simple interest accumulated

on a principal of $ 3,050.00

at a rate of 6% per year

for 3 years is $ 549.00.

9 blue marbles

3x=27

The equation which represents the given scenerio is 3b=27 and the number of blue marbles are 9.

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

Let b represents the number of blue marbles.

r represents number of red marbles in jar.

The number of red marbles in a jar is 3 times the number of blue marbles.

r=3b

There are 27 red marbles and b blue marbles.

27=3b

To find the number of blue marbles we have to solve the above equation.

Divide both sides by 3

27/3=3b/3

9=b

Hence, the equation which represents the given scenerio is 3b=27 and the number of blue marbles are 9.

Why am I baking cakes. I SUCK.

There are 12 ounces of sugar will he need in his smaller cake.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

The normal recipe calls for 8 ounces of butter and 16 ounces of sugar.

Let the amount of sugar will he need in his smaller cake = x

So, By definition of proportion, we get;

⇒ Amount of Butter / Amount of Sugar

⇒ 8 / 16 = 6 / x

⇒ x = 6 × 16 / 8

⇒ x = 12 ounces

Answer:

2. 4/11

3. 3/26

4. -18/5

Step-by-step explanation:

Answer:

Subtract 2 from both sides.

Step-by-step explanation:

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

> Also, note the equal sign, what you do to one side, you do to the other side of the equation.

First step is to subtract 2 from both sides of the equation:

3x + 2 (-2) = 29 (-2)

3x = 29 - 2

3x = 27

The second step is to divide 3 from both sides of the equation:

(3x)/3 = (27)/3

x = 27/3

x = 9

~

Answer:

The first step is subtracting the two on both sides.

Step-by-step explanation:

You arent exactly following PEMDAS in this equation, but you are still in a way. Before going on to x you need to go on to the numbers first. 3x would be equal to 27.

Answer:

Yes

Step-by-step explanation:

Given that :

CHAIN A:

Sample size n1 = 30

Sample standard deviation of waiting time s1 = 21.2

CHAIN B:

Sample size, n2 = 28

Sample standard deviation of waiting time s2 = 31.4

Null hypothesis H0: s1 = s2

Alternative hypothesis H1: s1 < s2

Test statistic ; Ftest : s1² / s2²

Ftest = 21.2^2 / 31.4^2

= 0.4558399

P value from F statistic : = 0.02 (using p value calculator)

Since the pval < 0.05

Then we reject the Null ; Chain A waiting time is more consistent
