A line passes through the point (4, - 7) and has a slope of
--
4
Write an equation in slope-intercept form for this line.

Answers

Answer: y = 4x-23

Step-by-step explanation:  I'm assuming the question asks:  "A line passes through the point (4, - 7) and has a slope of 4."  I had difficulty understanding the format of the question.  Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We can start with y = 4x + b, since we are given the slope.  We can then use the given point (4,-7) to find b, since this point is on the line and thus satisfies the equation.

y = 4x + b

-7 = 4(4) + b

-7 = 16 + b

b = - 23

The equation is y = 4x-23

What is the range of the function f(x) = 3x + 2
when the domain is {-2,-1,2}?

Answers

Answer:

Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)

Step-by-step explanation:

All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!

30% of the swimming team are girls. If there are 18 girls. How many are in the team
altogether?

Answers

Answer:

60 people are in the team altogether

Answer:

60

Step-by-step explanation:

to find the percentage of girls on the swim team, you would multiply a number by 30 percent. to find the number in all, you would divide 18 by 30 percent

18/0.3 = 60

there are sixty people on the swimming team

prove that 5^(2n - 1) is divisible by 8​

Answers

Your teacher must have made a typo somewhere. The expression 5^(2n-1) is not divisible by 8.

The expression 5^(2n-1) is composed of 2n-1 copies of "5" multiplied together. The key here is that 5 is the only unique prime factor of this number.

On the other hand, 8 = 2*2*2 = 2^3 showing that 2 is the only prime factor for this number. At this point, we can see that there's no way that 5^(2n-1) is divisible by 8. It all comes down to the clash of the primes 5 and 2 not matching up, and having nothing in common.

Let's consider a few concrete examples:

If n = 1, then 5^(2n-1) = 5^(2*1-1) = 5^1 = 5 which is not divisible by 8. The number 5/8 = 0.625 isn't an integer.If n = 2, then 5^(2n-1) = 5^(2*2-1) = 5^3 = 125 which is also not a multiple of 8. The number 125/8 = 15.625 isn't an integer.

I'll let you try other natural numbers for n, and you'll find that [tex]\frac{5^{2n-1}}{8}[/tex] isn't an integer.

In an auditorium, a charity show is conducted in order to raise at least $3,000. The auditorium can
accommodate up to 180 spectators. Tickets cost $12 for students and $20 for adults. Identify the system of
inequalities and the corresponding graph that determine whether the charity will reach its goal.

Answers

If the number of adults is more than or equal to 105, then the goal is achieved otherwise not achieved.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

In an auditorium, a charity show is conducted in order to raise at least $3,000.

The auditorium can accommodate up to 180 spectators.

Tickets cost $12 for students and $20 for adults.

Let x be the number of students and y be the number of adults. Then we have

x + y = 180

12x + 20y ≥ 3000

By solving, equations 1 and 2. Then we have

x = 75 and y = 105

If the number of adults is more than or equal to 105, then the goal is achieved otherwise not achieved.

The graph is given below.

How to find perimeter with equations

I attached a pic of the problem I’m really struggling with, if I could get a step by step explanation of how to do it that would be great. Thanks so much

Answers

Step-by-step explanation:

In blue colour square

Perimeter= 4 × side

= 4 (3x +7)

=12x +28 unit

In green colour square

Perimeter= 4 × side

= 4 ( 5x+1)

= 20x +4 unit

Answer:

12x + 28 = p

20x + 4 = p

Step-by-step explanation:

Assuming that both shapes are square, the perimeter of a square is the equation:

4 * x = p

Where x is the length of one side. Plug the variables in for the first square:

4 * (3x + 7) = p

Expand the brackets:

4 * 3x = 12x

4 * 7 = 28

12x + 28 = p

For the second square, plug the variables in again:

4 * (5x + 1) = p

Expand the brackets:

4 * 5x = 20x

4 * 1 = 4

20x + 4 = p

Hope this helps!
