Every day Amy travels 30 miles one-way to work. The park-and-ride where she catches the train is 5 miles from her home. The average speed of the train is 15 mph faster than the average speed in her car. Assuming she has no wait time for the train, her one-way trip takes 45 minutes. Find the speed of the car.

Answer: A, arithmetic

Step-by-step explanation:

An arithmetic sequence has a constant difference between each term. If she spend 36 dollars each week, the first week would be 36 the second week would be 72, and so on.

Answer:

There will be 330 7th grade students in this middle school this year.

Step-by-step explanation:

Last year enrollment = 150 students

As the enrollment increased by 120%.

i.e.

Number of Percentage increase = 120% × 150 = 120/100 × 150

                                                       = 1.2 × 150

                                                        = 180

Thus,

Total students this year = No. of Percentage increase + Last year students

                                       = 180+150

                                        = 330 students

Therefore, there will be 330 7th grade students in this middle school this year.

The mapping diagram that represents a relation that is not a function is the option A mapping diagram;

A. A mapping diagram with negative 6 pointing to negative 4 and 3; negative 1 pointing to 5; 7 pointing to 8

Step-by-step explanation:

The mapping diagrams of the given relations are presented using Microsoft Visio as seen in the attached drawings

From the given options, in option A, -5 is paired with both 4 and 3, therefore, giving an input or domain value, -5, that has two outputs in the range which are 4 and 3, therefore, the relationship between the left and right cells in option A is not a function because it is not defined as one input can have several outputs

5 Easy as 1-2-3

5 is a prime number.

Prime factorization: 5 is prime.

The exponent of prime number 5 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 5 has exactly 2 factors.

Factors of 5: 1, 5.

Factor pairs: 5 = 1 x 5.

5 has no square factors that allow its square root to be simplified. √5 ≈ 2.236.

Answer:

Step-by-step explanation:

ok slope is m because there is a thing called y-intercept, so you use x to find slope.

the whole formula is y = mx +b

in this case m = slope with x being the part of the slope from where you got it from

the answer would be m = [tex]\frac{1}{2}[/tex]x

Answer:

All but the second one

Step-by-step explanation:

Find the inverse of each function:

b(x)=x^2+3

y=x^2+3

x=y^2+3

x-3=y^2

sqrt(x-3)=y

This inverse function is a function

d(x)=-9

y=-9

This doesn't have an inverse function

m(x)=-7x

y=-7x

x=-7y

-1/7x=y

This inverse function is a function

p(x)=|x|

y=|x|

x=|y|

x=y

This inverse function is a function

Therefore, all but the second function have inverses that are functions

Answer:

All but the second one have inverse functions

Answer:

-15

Step-by-step explanation:

Well you cleary just divide the numbers But if you dont belive it use a caculator for this

-210 divided by 14 equals -15.

To divide -210 by 14, we set up the division equation: -210 ÷ 14.

Since we have a negative dividend, we know the quotient will also be negative.

We divide the absolute values of the numbers: 210 divided by 14, which equals 15.

Since the dividend and divisor have different signs, the quotient is negative.

Therefore, -210 divided by 14 equals -15.

This means that -210 can be evenly divided into 14 groups, each having a value of -15.

The negative sign indicates that the result is in the opposite direction or orientation compared to the positive value.

Answer:

8 (i think)

Step-by-step explanation:

Answer:

y = 4x - 6

Step-by-step explanation:

The y-intercept is the point where x is equal to 0. Therefore, the y-intercept is -6.

To find the slope we need to take 2 points and put them in the slope formula:

[tex]slope = \frac{y2-y1}{x2-x1}[/tex]

I am going to use the points (3,6) and (4,10). Plug these in to the equation:

[tex]\frac{10 - 6}{4 - 3} = \frac{4}{1} = 4[/tex]

The slope is 4.

The whole equation can be written now:

y = 4x - 6

48√2 in the simplest form of the expression √192.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can simplify the √192 by factoring it into its prime factors:

192 = 2 × 2 × 2 × 2 × 2 × 3 × 3

Then, we can group the prime factors into pairs of two:

192 = (2 × 2) × (2 × 2) × (2 × 3) × 3

Simplifying each pair of factors under the square root gives:

[tex]\sqrt{192} = \sqrt{(2\times2)}\sqrt{(2\times2)}\sqrt{(2\times3)}\sqrt{3}\\= 4\times4\times\sqrt{6}\sqrt{3} \\= 16\sqrt{6}\sqrt{3}[/tex]

Finally, we can simplify the expression by multiplying the coefficients and combining the square roots:

[tex]16\sqrt{6}\sqrt{3} \\= 16\sqrt{18} = 16\sqrt{2\times3\times3} \\= 16\times3\sqrt{2} \\= 48\sqrt{2}[/tex]

Therefore,

48√2 in the simplest form of the expression √192.

Answer: 32 male supertasters

Step-by-step explanation:

Let the number of men classified as supertaster be represented by m.

Since the number of women classified as supertasters was 2.25 times the number of men classified as supertaster. This means that:

Women (w) = 2.25m

If 72 women were classified as supertasters, the equation that represents the number of men, m, who were classified as supertasters will be:

2.25m = 72

m = 72 / 2.25

m = 32

There are 32 men supertasters.

2p - 3q - 4r + 6r - 2q + p = 0

2p + p - 3q - 2q - 4r + 6r = 0

3q - 5q + 2r = 0
