Answer:

[tex]y = 48000 - 2200x[/tex] --- equation

[tex]y = 37000[/tex] --- value at 5th year

Step-by-step explanation:

Given

[tex]Value = \$48000[/tex]

[tex]Rate = \$2200[/tex] decrease

Required

Determine the linear equation

Determine the value at the 5th year

Represent years with x.

If the rate in 1 year is 2200,

in x years, it'll be 2200x (decrement)

So, the value (y) at x years is.

[tex]y = 48000 - 2200x[/tex]

The value at the 5th year is when x = 5.

So, we have:

[tex]y = 48000 - 2200 * 5[/tex]

[tex]y = 48000 - 11000[/tex]

[tex]y = 37000[/tex]

Answer:

Integers: -25, 3, -5, 0

Not Integers: 1/2, 8.1

Step-by-step explanation:

Integers are whole numbers that appear on a number line. Any number that is not a whole number is not an integer.

Answer:

Integers::3,-5,0    

Not Integers:-2.5,1/2,8.1

Step-by-step explanation:

Integers are WHOLE numbers both + and - they cannot be fractions or decimals

Answer:

[tex]\huge\boxed{7\ \text{inches}}[/tex]

Step-by-step explanation:

As I mentioned earlier with a single side (line), rotations do not change the size of something. Only dilations do that. This goes for both lines AND shapes.

However, if the question said she dilated the piece, then yes, the length in inches would be different. However, rotation just changes the position and nothing happens to the length.

Let, speed of car B is -x.

So, speed of car A is x + 10.

Relative speed of A w.r.t B is ,

[tex]v_{ab}=(x+10)-(-x)\\\\v_{ab}=2x+10\ mph[/tex]

So, time taken by A to travel 300 miles relative to B given by 3 hours .

[tex]v_{ab}=2x+10\\\\\dfrac{300}{3}=2x+10\\\\x = 45 \ mph[/tex]

Therefore, speed of car A is 45 + 10 = 55 mph.

Hence, this is the required solution.

Answer:

B

Step-by-step explanation:

Mathematically, we shall be using the z-score here

Z-score = (x-mean)/SD

From the question, mean = 80 and SD = 4

So we want to get the option in the question that has a z-score of 1 or below

Let’s look at 75

80-75 = 5 ( this is clearly above 1 standard deviation of 4)

For 77;

80 -77 = 3

This is less than the standard deviation of 4, meaning it is within 1 standard deviation of the mean

Option B) is correct.

Step-by-step explanation:

Given :

Mean [tex](\mu)[/tex]  = 80

Standard Deviation [tex](\sigma)[/tex]  = 4

Calculation :

We have to find the score that would be 1 deviation from the mean. Which means, the interval [tex](\mu-\sigma, \mu+\sigma)[/tex]

[tex]\mu-\sigma = 80-4=76[/tex]

[tex]\mu+\sigma =80+4=84[/tex]

The interval is (76,84)

Therefore, option B) is correct.

Answer:

D) -3y + 8z

Step-by-step explanation:

2x - 2y + 5z - 2x - y + 3z

first, group the same variables together.

2x - 2x - 2y - y + 5z + 3z

then, this step which I don't have a name for.

2x - 2x = 0x.

-2y - y = -3y

5z + 3z = 8z

0x - 3y + 8z

or, -3y + 8z

Answer:

x=37 Hope this helped <3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+7=2(x−15)

x+7=(2)(x)+(2)(−15)(Distribute)

x+7=2x+−30

x+7=2x−30

Step 2: Subtract 2x from both sides.

x+7−2x=2x−30−2x

−x+7=−30

Step 3: Subtract 7 from both sides.

−x+7−7=−30−7

−x=−37

Step 4: Divide both sides by -1

Answer:

[tex]\boxed {x = 37}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]x + 7 = 2(x - 15)[/tex]

-Use Distributive Property:

[tex]x + 7 = 2(x - 15)[/tex]

[tex]x + 7 = 2x - 30[/tex]

-Take [tex]2x[/tex] and subtract it from [tex]x[/tex]:

[tex]x + 7 - 2x = 2x - 2x - 30[/tex]

[tex]-x + 7 = -30[/tex]

-Subtract [tex]7[/tex] to both sides:

[tex]-x + 7 - 7 = -30 - 7[/tex]

[tex]-x = -37[/tex]

-Divide both sides by [tex]-1[/tex]:

[tex]\frac{-x}{-1} = \frac{-37}{-1}[/tex]

[tex]\boxed {x = 37}[/tex]

So, the value of [tex]x[/tex] is [tex]37[/tex].

Answer:

10 months

Step-by-step explanation:

Let x denotes number of months.

Down payment of first TV = $200

Per month payment of first TV = $39.99

Total payment of first TV [tex]=200+39.99x[/tex]

Down payment of second TV = $0

Per month payment of second TV = $59.99

Total payment of second TV [tex]=0+59.99x=59.99x[/tex]

To find number of months until the payments are of equal value,

solve [tex]200+39.99x=59.99x[/tex]

[tex]200+39.99x=59.99x\\200=59.99x-39.99x\\200=20x\\x=\frac{200}{20}\\ x=10[/tex]

So, payments become of equal value after 10 months.

Answer:

The domain is continuous and the weight y of x identical hardcover books

Step-by-step explanation:

Discrete means non continuous data. This is continuous and equal so the domain is continuous.

Also, precipitation each week can vary so that won't work. Eating carrots each day can also vary so that doesn't work. The cost of an item can vary almost every day! So that is not true.

Therefore it is the last one, because it is identical and all of the coordinates make (1,3).

Step-by-step explanation:

Answer: this is how you do it

Step-by-step explanation:

For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.

Answer:

x = 3

Step-by-step explanation:

Since the 3 angles in the triangle are equal, then the triangle is equilateral.

Thus the 3 sides are congruent.

Equate any 2 of the sides and solve for x, that is

12x - 13 = 7x + 2 ( subtract 7x from both sides )

5x - 13 = 2 ( add 13 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3
