Answer:

(2[tex]b^{2}[/tex] - 5) (3b + 8)

Step-by-step explanation:

First factor out 2[tex]b^{2}[/tex] from the first set of parentheses and -5 from the second

2[tex]b^{2}[/tex] ( 3b + 8)  - 5 (3b + 8)

Next factor out (3b + 8)

(2[tex]b^{2}[/tex] - 5) (3b + 8)

Answer:

x = 5/3, 1/3

Or

x=1.6 repeating ,0.3 repeating

Answer:

86

Step-by-step explanation:

average is calculated as

average = [tex]\frac{sum}{count}[/tex]

given her average was 70 in 3 tests , then

[tex]\frac{sum}{3}[/tex] = 70 ( multiply both sides by 3 )

sum = 210

let the score she must get in test 4 be x for an average of 74 , then

[tex]\frac{210+x}{4}[/tex] = 74 ( multiply both sides by 4 )

210 + x = 296 ( subtract 210 from both sides )

x = 86

she must score 86 in her next test

Answer:

[tex]\frac{x}{3}[/tex]= 70

x=210

[tex]\frac{210+x}{4}[/tex] = 74

210+x=74x4

210+x=296

x=296-210

x=86

Let's call the amount of lugagge the first men had as x, and the amount of lugagge the second men had as y.

Since both had to pay for excess of luggage, both had the permitted amount of luggage plus an extra amount. Let's call the permitted amount as a, the extra the first men had as z, and the extra the second man had as w. Then, our total amounts of luggage can be rewritten as

Since their total amount of luggage added together was 135 kg, this gives to us the following equation

The charge for the extra luggage is a flat rate, let's call it r, then, the price you pay for the extra luggage is given by the product between this rate and the amount of extar luggage. The first paid $1.35 for his excess luggage and the second paid $2.70 for his excess luggage, therefore

If we divide one equation by the other, we can write the excess of luggage of one as a function of the other.

If all of the luggage belonged to one person, this person would have to pay $8.10 for the excess. If we call the excess of this person as p, the amount of luggage this person had would be

Using the "rate formula" we created before, we can also write p as a function of z.

Rewritting all the total amounts, we have

If we add the equations for x and y together, we have

From the first equation, we know that the sum between both total amounts of luggage is equal to 135.

Now, we have two equations for our two variables.

If we multiply the first equation by 2, and subtract the second equation, we're going to get a new equation only for a(the amount in kilograms of permitted luggage).

The amount of luggage permitted to bring onto the plane for free is 45 kilograms.

The estimate of the average rate of change f is -2

The possible graph that completes the question is added as an attachment

The interval is given as

-1 ≤ x ≤ 0

This can be rewritten as

x = -1 to x = 0

This can also be represented as

(a, b) = (-1, 0)

From the attached graph, we have

f(-1) = 7

f(0) = 5

The estimate (to one decimal place) of the average rate of change f is

Rate = [f(b) - f(a)]/[b - a]

This gives

Rate = [f(-1) - f(0)]/[-1 - 0]

So, we have

Rate = [7 - 5]/[-1 - 0]

Evaluate

Rate = -2

Hence, the average rate of change f is -22

a) The minimum number of dogs that could have a mass of more than 27 kg is 4.

b) The maximum number of dogs that could have a mass of more than 27 kg is 17.

The given table shows information about the masses of some dogs.

a) Because we need the minimum number of dogs,

Let's assume all dogs present in the interval 20 to 40 have a mass of more than 27kg so the minimum value out of 13 and 4 is 4.

b) Because we need the maximum number of dogs,

Let's assume all dogs present in the interval 20 to 40 have a mass of more than 27kg so the maximum of the values present in the interval 20 to 40 is 13 + 4 = 17

-by-step explanation:

The number you should multiply 3 1/3 to get a product of 4 is 1 1/5

From the question, the statement is given as

What number should you multiply 3 1/3 to get a product of 4

Let the number be x

So, we have the following representation

3 1/3 * x = 4

Express 3 1/3 as an improper fraction

So, we have the following representation

10/3 * x = 4

Multply both sides by 3

So, we have

10 * x = 12

Divide both sides by 10

This gives

x = 12/10

Express as mixed numbers

x = 1 1/5

Hence, the number is 1 1/5

<8,<4, <1, <5 all equal 66° since vertical angles are equal

The slope of the ramp is m =  h/√(r² - h²).

What is mean by square root of a number?

A square root of a number is a value that multiplied by itself gives the same number.

Let h = height of the landing.

And, r = the length of the ramp.

Then, the length from the ground where the ramp touches it, to the ground directly below the landing is

⇒ √(r² - h²)

And, The slope of the ramp is m =  h/√(r² - h²)

For example, if the ramp is 5 meters long and the landing height is 3 meters high, the slope of the ramp is 3/4.

As, Slope of the ramp (m) = 3/√(25-9)  = 3/√16  = 3/4

Thus, The slope of the ramp is m =  h/√(r² - h²).

The inequality which is represented by the dashed line and the description as in the task content is; y < Negative three-halvesx + 1.

It follows from the task content that the inequality which correctly represents the line is to be determined.

Therefore, first, the slope which is the rate of change of y to x according to the two points given is;

slope, m = (y2 - y1)/(x2 - x1)

m = (-2 - 1)/(2 - 0)

m = -3/2.

Also, since the point, (0, 1) is given, the y-intercept of the line is; 1.

Therefore the equation of the dashed line is;

y = (-3/2)x + 1.

And ultimately, since the line is dashed and everything to the left is shaded, the required inequality is;

y < (-3/2)x + 1.
