The sum of four consecutive even integers is -892. Find the four numbers.

Answers

Divide by the amount of consecutive numbers (4 in this instance)

It will be within a small range of those numbers

ex. The sum of 3 consecutive even integers is 24.

24/3 =8

Now guess and check

4+6+8=18 that's not 24 so don't add 4 instead on the other side of 8 put 10

6+8+10=24

Do roughly the same thing

All four consecutive even integers are;

-226 , -224 , -222 , -220

What is Integers?

An integers is a whole number which can be positive, negative or zero.

Given that;

Sum of four consecutive even integers is -892.

Let four consecutive even integers are;

2x , 2x + 2 , 2x + 4 and 2x + 6

Since, Sum of four consecutive even integers is -892.

Hence, We can formulate;

2x + 2x + 2 + 2x + 4 + 2x + 6 = -892

8x + 12 = -892

Subtract 12 both sides,

8x + 12 - 12 = -892 - 12

8x = -904

Divide by 8,

x = -904 / 8

x = - 113

So, All four even numbers are;

2x = 2 × -113 = -226

2x + 2 = -226 + 2 = -224

2x + 4 = -226 + 4 = -222

2x + 6 = -226 + 6 = -220

Thus, All four consecutive even integers are;

-226 , -224 , -222 , -220

Answer:

y=6/2x-6

y=3x-6

Step-by-step explanation:

you are filling in y= mx + b
m= slope and b= y-intercept

start by finding where the line intercepts the y axis.
it crosses at (0,-6)

2. find a perfect point on the graph and move up then over until you reach another perfect point. However many times you go up, is your numerator and left or right is your denominator.
For this equation it is 3/1, it can simplify to 3. This number is the slope.

Finally, fill the numbers into the equation.

So the answer is y= 3x - 6

A car dealership sells sedans and SUVs. In 2000, the ratio in which they were sold was 5:4. By 2010, the dealership had adjusted its inventory to a 2:7 ratio. If it sold 84 SUVs in 2010, how many sedans did it sell in 2000?

Answers

Answer:

60 sedans

Step-by-step explanation:

The computation of the number of sedans sold in 2000 is given below:

Given that

The ratio of sedans and SUV is 5:4

And, in 2010 its ratio is 2:7

Now in 2010, 84 SUVs sold

So

84 SUVS = 7

For total 9, it would be

= 84 × 9 ÷  7

= 108 vehicles

Now the number of sedans is

= 108 × 5 ÷ 9

= 60 sedans

Han's family got a solar panel. Each month they get a credit to their account for the electricity that is generated by the solar panel. The credit they receive varies based on how sunny it is. In January they used $83.56 worth of electricity and generated $6.75 worth of electricity. Here is their electricity bill from January. Current charges: $83.56 Solar Credit: -$6.75 Amount due: $76.81 1) In July they were traveling away from home and only used $19.24 worth of electricity. Their solar panel generated $22.75 worth of electricity. What was their amount due in July?

Answers

Answer:

-$3.51

Step-by-step explanation:

Given that :

Current charges:

$83.56 Solar Credit: -$6.75

Amount due: $76.81

July they were traveling away from home and only used $19.24 worth of electricity. Their solar panel generated $22.75 worth of electricity. What was their amount due in July

Worth of electricity used in July = $19.24

Worth of electricity generated by solar = - $22.75

Electricity used in July + solar credit charge

$19.24 - $22.75

= -$3.51

3. The functions f and g are defined by f: x → ax – b where a and b are constants and g: x → X+4.
Given fg(2) = 9 and gf (1/2) = 2, find the value of a and of b. ​

hiii this is adddmath can anyone help with this please

Answers

Answer:

fg(2) = 9 means that f(g(2)) = 9

We know that g(2) = 6

So f(6) = 9 which means that

6a - b = 9 (note 1)

And we know that g(f(1/2)) = 2

And we know that f(1/2) = 1/2(a) - b

So g(1/2(a) - b) = 2

Meaning that 1/2(a) - b + 4 = 2

So 1/2(a) - b = - 2 (note 2)

Using note 1 and 2 we can solve the equation

11/2(a) = 11 so a = 2 and b = 3

A shipping box is in the shape of a rectangular prism. It has a volume of 9,000 in.3, and the dimensions of the base are 20 in. by 30 in. What is the height of the box?

Answers

Answer:

A closed box is to be made in the shape of a cuboid of height h (in cm) with a rectangular base that has sides of length x (in cm) and 2x (in cm). Its volume is required to be `1000 cm^3

The height of the shipping box is 15 inches.

What is volume of rectangular prism?

The volume of a rectangular prism: length x width x height. The volume is expressed in cubic units.

given:

Volume = 9000 cubic inches

Base dimensions = 20 inches by 30 inches

Now, Volume = Base Area * Height

Height = Volume/Base Area

Height = 9000/(20 * 30)

Height = 15 in

Hence, the height of the shipping box in the shape of a rectangular prism is 15 inches.
