Write the equation for the line with the given points (0,-3) and (2,9) in point slope form

Answers

Equation: Y = mx + b
First of all, we will solve for our M which is our slope.
M = Yb - Ya / Xb - Xa
M = 9 - (-3) / 2 - 0
M = 9 + 3 / 2 - 0
M = 12 / 2
M = 6

Now that we have our slope, we will be finding our y-intercept.
Y = mx + b
9 = (6)(2) + b
9 = 12 + b
= 9-12 = 12-12 + b (12 cancels out)
= -3 = b

So, therefore, the equation is: Y = 6x - 3

Which value of x is a solution of the inequality 25x - 100 < 250?

Answers

Answer:

inequality form: x<14

Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.

The solution of the given inequality is set of all x such that x < 14.

What are Inequalities?

Two or more expressions connected with symbols of inequality like ≥, ≤, > and < is called the inequalities.

There are different kinds of inequalities like polynomial inequalities which includes linear inequalities and quadratic inequalities, rational inequality and so on.

Linear inequalities will have the highest degree of the variable equals 1.

Given a linear inequality,

25x - 100 < 250

Adding both sides of the inequality with 100,

25x - 100 + 100 < 250 + 100

25x < 350

Dividing both sides of the inequality by 25,

25x / 25 < 350 / 25

x < 14

Hence the value of x in the inequality is all the values of x which are less than, < 14.

Step-by-step explanation:

Notice that:

15x = 5 * 3x and 10y = 5 * 2y.

Since there is a common factor of 5,

we can take out the factor.

=> 15x + 10y = (5)(3x) + (5)(2y) = 5(3x + 2y).

Of 100 musicians at a high school, some play only in the jazz band, some play only for the marching band, and some do both. If 60
of them play in the jazz band, and 25 play in both, how many of the musicians are only marching band?
A)
25

B)
60
c)
40
D)
35

Answers

Answer:

There are 40 musicians that are only marching band.

Step-by-step explanation:

Since we knot that there are 25 musicians that do both that means there is 60 - 25 = 35 musicians who do only jazz band. From his we can answer the question because....

100 = a + b + c

Where "a" is the number of musicians who go only to jazz, "b" is the number of people who do both, and "c"  is the number of people that go only to the marching band. From here we can do this....

100 = a + b + c

c = 100 - a - b

Substitute the value we found outa and get.....

c = 100 - 35 - 25

c = 40

Answer:

There are 40 in the marching band

-28x + 24 = 120 - 20x

Rewrite the explicit formula in function form. The identify the y-
intercept of the function.
an = 10+2(n-1)

Answers

Answer:

We have the relation:

aₙ = 10 + 2*(n - 1)

And we want to write this in fuction form:

y = f(n)

first we have:

aₙ = y =  10 + 2*(n - 1)

We can rewrite this as:

y = 10 + 2*n - 2

y = 2*n + (10 - 2)

y = 2*n + 8

Now we want to find the y-intercept, this is the value of the function when the variable is equal to zero.

Then if we take n = 0, we get:

y = 2*0 + 8

y = 8

The y-intercept is 8.

Which graph represents f(x) and the inverse f^-1(x)

Answers

Answer:

D

Step-by-step explanation:

The inverse or f⁻¹(x) of a function f(x) is the graph being reflected over the line y = x.

For A, f(x) is reflected over the x-axis.

For B, f(x) is rotated about a point.

For C, f(x) reflected over the y-axis.

And for D, f(x) is reflected over the line y = x.

So, the graph that represents f(x) and its inverse f⁻¹(x) is choice D.

A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s and the water strikes the door horizontally and doesnt bounce back. What average force is exerted by the stream of water?

Answers

Answer:

[tex]6400\ \text{N}[/tex]

Step-by-step explanation:

[tex]\dfrac{m}{t}[/tex] = Mass flow rate of water = 320 kg/s

[tex]m[/tex] = Mass of water on the door

[tex]t[/tex] = Time

[tex]v[/tex] = Velocity of water on the door = 20 m/s

Force is given by

[tex]F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}[/tex]

The average force is exerted by the stream of water is [tex]6400\ \text{N}[/tex].

(2 points) Part C: Solve the system from (b) by using either substitution or elimination *show all solving steps*. (4 points) Part D: Write a solution statement answering the question

Answers

Answer:

Jackie collected 61 coins and 20 stamps

Step-by-step explanation:

Solving (a): Variable representation

Let the coins be represented with c

Let the stamps be represented with s

Solving (b): Setup equation

Total is 81. This implies that:

[tex]s + c = 81[/tex]

Also:

[tex]c = 1 + 3s[/tex]

Solving (c): Solve the system

Substitute 1 + 3s for c in [tex]s + c = 81[/tex]

[tex]s + 1 + 3s = 81[/tex]

Collect Like Terms

[tex]s + 3s = 81-1[/tex]

[tex]4s= 80[/tex]

Divide both sides by 4

[tex]s = \frac{80}{4}[/tex]

[tex]s= 20[/tex]

Substitute 20 for s in [tex]c = 1 + 3s[/tex]

[tex]c = 1 + 3 * 20[/tex]

[tex]c = 1 + 60[/tex]

[tex]c = 61[/tex]

Volunteers give back to the community, provide meaningful assistance to people in need, and use their expand skills to improve the quality of life for others. However, the rewards of Volunteering are not only based on giving. In fact, the act of Volunteering may be even more beneficial to volunteers them selves than to the people they support. Volunteers are Individuals who choose to provide assistance in many areas, from working with senior citizens, to walking dogs at the shelter, to building homes for the homeless. Volunteers are form all walks of life, but many work or go to school full time and arrange their busy schedules to work with others early mornings, evenings, or weekends. Some would argue that Volunteering adds significant to work with others hectic lives. Interestingly, studies show that Volunteering actually helps reduce stress, because individuals who volunteer report feeling a greater sense of purpose and self-worth. This happens because volunteers build strong social relationships that help carry them through challenging times. The act of helping others and making a difference actually enhances their life experience. As a result, research demonstrates that people who volunteer have lower mortality rates, better physical health, and lower rates of depression later in life than those who do not volunteer.
