Steps to solve:

3x - 8 = -2; x - 6

~Substitute

3(x - 6) = -2

~Distribute left side

3x - 18 = -2

~Add 18 to both sides

3x = 16

~Divide 3 to both sides

x = 16/3

Answer:

Ok, we have:

d(t) = 3*t^2 + 5*t - 2.

The first interval is:

(2, 3)

and remember that, for an interval (a,b), the difference quotient is:

D = (f(b) - f(a))/(b -a)

Then in this first interval we have:

[tex]d = \frac{d(3) - d(2)}{3-2} = \frac{3*3^2 + 5*3 - 2 - (3*2^2 + 5*2 - 2)}{1} = 20[/tex]

So the average rate of change in (2,3) is 20.

now, in (2, 2.5) we have:

[tex]d = \frac{d(2.5) - d(2)}{3-2} = \frac{3*2.5^2 + 5*2.5 - 2 - (3*2^2 + 5*2 - 2)}{1} = 9.25[/tex]

So here the rate of change is 9.25

And in the interval (2, 2.1) we have:

[tex]d = \frac{d(2.1) - d(2)}{3-2} = \frac{3*2.1^2 + 5*2.1 - 2 - (3*2^2 + 5*2 - 2)}{1} = 1.73[/tex]

So in this interval the rate of change is 1.73

Answer:

2 to 3 is 20

2 to 2.5 is 15

2 to 2.1 is 11

I got this question right on EDGE 2023

Answer: 90

Step-by-step explanation:

We first need to find three consecutive numbers that adds up to 267. We know that the numbers will be somewhat close to 100 because the sum needs to be past 250.

Let's try 85,86,87.

85+86+87=258

258 is very close to 267. We know that we need to increase our numbers.

Let's try 88,89,90.

88+89+90=267

88,89, and 90 added together gives us 267. The question asks for the largest integer. In 88, 89, 90, 90 is the largest integer.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other side. Do the opposite of PEMDAS. Isolate the variable, x.

PEMDAS is the order of operation, and =

First, subtract 7y from both sides:

3x + 7y (-7y) = 27 (-7y)

3x = -7y + 27

Next, divide 3 from all terms on both sides:

(3x)/3 =  (-7y + 27)/3

x = (-7y/3) + 9

[tex]x = \frac{-7y}{3} +9[/tex]

Answer:

Restaurant Server: 10%

Florist: 10%

Cab Care: 0%

Dog Groomer: 5%

Step-by-step explanation

Also, in the question it says round to make a more resonable number for example in the chart for the resturant it says the cost is $40 dollars and the gratuity is 18% and the tax is 8.5% with this you round 18% to 20% and the tax 8.5% to 9% and round that to 10% and when you round the  tax to 10% that is your anwser. Then with all the other numbers on the chart do the same thing and there is all of your anwsers.

Restaurant Server: 8%

Florist: 12%

Cab Fare: 0%

Dog Groomer: 6%

Restaurant Server:

The cost is $40 and the gratuity is 18%.

To calculate the tax, you multiply the cost by the tax rate, which is 8.5% (or 0.085).

The tax amount would be $40 × 0.085 = $3.40. Rounding this to the nearest whole number would be $3.

Therefore, the tax estimate for the restaurant service would be 8%.

Florist:

The cost is $94 and the gratuity is 12%.

The tax rate for the florist service is 12% (or 0.12).

Calculating the tax amount would be $94 × 0.12 = $11.28. Rounding this to the nearest whole number would be $11.

Hence, the tax estimate for the florist service would be 12%.

Cab Fare:

The cost is $32, and the gratuity is 20%.

The tax for cab fares is mentioned as 0%, which means there is no tax applicable. In this case, rounding is not necessary as the tax amount is already 0%.

Dog Groomer:

The cost is $62, and the gratuity is 26%. The tax rate for the dog groomer service is 5.75% (or 0.0575).

Calculating the tax amount would be $62 × 0.0575 = $3.57.

Rounding this to the nearest whole number would be $4.

Thus, the tax estimate for the dog groomer service would be 6%.

-3(6 - 2x) > 4x + 12

-18 + 6x > 4x + 12

2x > 30

x > 15

The solution set is (15, ∞).

The interval that includes all possible values of x that satisfy the inequality is (15, infinity), which can be written as [15, oo) in interval notation.

The answer is (d) [15,00)

The intervals are numbers or values between two given point

The intervals are denoted as:

Closed intervals = [a, b]

This interval includes a and b.

Open intervals = (a, b)

This interval does not include a and b.

We have,

We can solve the inequality as follows:

-3(6 - 2x) > 4x + 12

Distribute the -3 on the left side:

-18 + 6x > 4x + 12

Subtract 4x from both sides:

2x > 30

Divide both sides by 2:

x > 15

Therefore,

The interval that includes all possible values of x that satisfy the inequality is (15, infinity), which can be written as [15, oo) in interval notation.

The solution to the equation is n = -2.

To solve the equation 30 = -5(6n + 6) step-by-step, follow these procedures:

Step 1: Distribute the -5 on the right side:

30 = -5 * 6n - 5 * 6

Step 2: Simplify the right side:

30 = -30n - 30

Step 3: Move constant term to one side:

30 + 30 = -30n

Step 4: Combine like terms:

60 = -30n

Step 5: Divide both sides by -30 to isolate 'n':

Answer:

7 pounds 3 ounces

Step-by-step explanation:

There are 16 ounces in a pound. In order to convert ounces to pounds, we need to see how many 16s fit into 115 (how many full pounds can be made with 115 ounces) and add the remainder as ounces. To do this we can do long division (which gives us 7 remainder 3), or we can divide 115 by 16 (=7.1875) and convert the decimal places to ounces by multiplying 0.1875 pounds (the remainder) by 16 (as there are 16 ounces in pound) which gives us 3 ounces.

So 115 ounces is equal to 7 pounds and 3 ounces.

Hope this helped!

The baby's weight is 7 pounds and 3 ounces.

To convert ounces to pounds, we need to divide the number of ounces by the conversion factor, which is 16. There are 16 ounces in 1 pound.

Let's denote the baby's weight in ounces as W oz, the weight in pounds as W lb, and the remaining ounces as Roz.

W oz = 115 ounces

W lb = ?

R oz = ?

First, we divide the total number of ounces by 16 to find the number of pounds:

W lb = W oz / 16

= 115/ 16

= 7.1875 pounds

So, the baby weighs 7 pounds.

To determine the remaining ounces, we multiply the decimal portion of the pounds (0.1875) by 16:

R oz = 0.1875 x 6

R oz= 3 ounce

So, the baby weighs an additional 3 ounces.

Therefore, the baby's weight is 7 pounds and 3 ounces.

Answer:

C, 38°

Step-by-step explanation:

ray UW is the angle bisector of ∠VUT

--> m∠VUW = m∠WUT = 1/2 m∠VUT

<=> 4x + 6 = 6x - 10

<=> 6 + 10 = 6x - 4x

<=> 2x = 16

<=> x = 8

So, the measure of m∠WUT is: 6x - 10 = 6 . 8 - 10 = 48 - 10 = 38°
