Answer:

6x+35

Step-by-step explanation:

Answer:

6x + 35

Step-by-step explanation:

8x + 3x + 15 - 5x + 20

11x - 5x + 15 + 20

6x + 35

Answer:

y = 32x + 198

Step-by-step explanation:

The fastest way to go about this is to establish "m" and plug in the coordinates you want.

y = 32x + b

6 = 32 (-6) + b

6 = -192 + b

198 = b

y = 32x + 198

Answer:

The second one

Step-by-step explanation:

a linear function is one who's graph is a straight line.

A parabola is not linear.

Anything in the form k/x is not linear either.

5/6x = y-4

gives

y = 5/6x+4, which is a linear equation

Answer: B. -4 5/12

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

Step-by-step explanation:The answer is - 12 because the temperature started changing when it raised 3+ and then it changed again by dropping -15 so, then you do 3-15 and that equals (-12).

Answer: 40/10=4

That means 10% of 40 is 4.

Know that means you have to times 4 by 8

4x8=32

Now you know what 80% of 40 is.

Now we need to know what the 5% is. So if 4 is 10% . 5% must be 2.

Next we have to add 2 to 32.

32 + 2 = 34

Answer:

[tex]m = \frac {1}{4}[/tex]

Step-by-step explanation:

Slope formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here

[tex](x_1, y_1) = (-3, -1) \ \ and \ \ (x_2, y_2)= (5, 1)[/tex]

Slope can be calculated as

[tex]m = \frac{1-(-1)}{5-(-3)}[/tex]

[tex]m = \frac{2}{8} \\m = \frac {1}{4}[/tex]

Answer:

15.1

Step-by-step explanation:

The equation to solve this is 12.3 - -2.8. Since there are two negatives, it becomes a positive.

Therefore the equation becomes 12.3 + 2.8 and the answer is 15.1

Answer:

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Let V be the volume of the sphere

Given

Volume of sphere = V = 4500 cubic inches

Let r be the radius of the sphere

The volume of the sphere is given by the formula

[tex]V = \frac{4}{3}\pi r^3[/tex]

Putting the known values

[tex]4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636[/tex]

Taking cube root on both sides

[tex]\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403[/tex]

Rounding off to nearest hundredth

The radius is: 10.24 inches.

Hence,

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Given the algebraic expression

9r+2

We know that 9r is the product of 9 and 3.

Thus,

9r+2 can be verbally expressed in many ways such as:

Two more than 9 times a number, r.

or it can be also verbally expressed such as:

9 times a number, r, increase by 2.

Therefore, we conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:

Answer:

71

Step-by-step explanation:

Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd

71

We do not need to look at all differences.

We need to find two numbers fairly far appart,

and not all look promising.

You could look at approximate differences,

or you could look at the last digit.

71-35 and 63-17 are the only promising differences,

because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,

and when you calculate the last digit you calculate

11-5=6 and 13-7=6.

71-35=36

Answer:

The relation between the time and the distance will be:

y = 15x

The graph of the equation y = 15x is attached below.

Step-by-step explanation:

We know that the equation of linear function in two variables in the slope-intercept form is

y = mx+b

where

Let y be the distance

Let t be the time

Given that the object moves 15 meters in 1 second.

Thus, the rate of change or slope = m = 15

As there is no initial condition in our case.

Thus the y-intercept b = 0

Now, substituting m = 15 and b = 0 in the linear function

y = mx+b

y = 15x + 0

y = 15x

Therefore, the relation between the time and the distance will be:

y = 15x

The graph of the equation y = 15x is attached below.

Examples:

Calculate the distance in 1 second

put x = 1 in the equation

y = 15(1) = 15 meters

Calculate the distance in 10 second

put x = 10 in the equation

y = 15(10) = 150 meters

Answer:

3x+y

Answer:

E. 11

Step-by-step explanation:

Replace the m with 11.

11-8[tex]\leq[/tex] 2  this would simplify to

3 [tex]\leq[/tex]2 which is false.

However if you took m and replaced it with 10

10-8[tex]\leq[/tex]2 and simplified

2[tex]\leq[/tex]2 which is true. Therefore any number 10 or lower would make this true.

Answer:

-9.3x + 13.1y

Step-by-step explanation:

(3.5x - 2.7y) + (-12.8x + 15.8y) = 3.5x - 2.7y - 12.8x + 15.8y =

= 3.5x - 12.8x - 2.7y + 15.8y = (3.5 - 12.8)x - (2.7 - 15.8)y =

= -(12.8 - 3.5)x + (15.8 - 2.7)y = -9.3x + 13.1y

because

-(-a) = a

-(a + b) = -a - b

-(a - b) = -a + b = b - a

a + (-b) = a - b
