Answer 1

Answer:y-10=5/2(x-4) (the third choice)

Step-by-step explanation:

Point slope form is

y-y1=m(x-x1)

So y-10=5/2(x-4)

Two functions are shown below
f(x)=2x+1 g(x)=−72x−5
What is the approximate value of x when f(x) = g(x)?
A.1.3
B.0.5
C.1.8
D.3.1

Answers

f(x)= g(x) so 2x+1 = -72x-5
2x+72x = -1-5
74x = -6
x= -3/37 = 0.08 so option B

In a certain country the fines for speeding in a school zone are $160 plus an additional $4 for every mile per hour over the speed limit. A. Write a function to represent the speeding fines

Answers

Answer:

T= 160 + 4x

Step-by-step explanation:

Giving the following information:

The $160 fine is a fixed cost. It will remain constant.

The $4 additional fine acts as a variable cost. It varies with the number of miles per hour.

To calculate the total cost (T), we need to use the following formula:

T= 160 + 4x

x= miles per hour exceeding the speed limit.

Leslie's sister gave Leslie $120 as her celebration gift to get a job. Leslie put all the money into her bank account. Then she started save $100 each month. a. Write an equation in slope-intercept form (v = mx + b) to describe the relationship number of month and the total amount of savings.

Answers

Answer:

v = $100x + $120

Step-by-step explanation:

In this scenario, the fixed amount would be the $120 that Leslie's sister gave her. While $100 would be multiplied by the number of months (x) that have passed by which in this scenario would be our variable since we do not have this information. Lastly, these two values would be added to give us Leslie's total savings (v)

v = $100x + $120

The value of sin(2x) is [tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

How to determine the value of sin(2x)

The cosine ratio is given as:

[tex]\cos(x) = -\frac 14[/tex]

Calculate sine(x) using the following identity equation

[tex]\sin^2(x) + \cos^2(x) = 1[/tex]

So we have:

[tex]\sin^2(x) + (1/4)^2 = 1[/tex]

[tex]\sin^2(x) + 1/16= 1[/tex]

Subtract 1/16 from both sides

[tex]\sin^2(x) = 15/16[/tex]

Take the square root of both sides

[tex]\sin(x) = \pm \sqrt{15/16[/tex]

Given that

tan(x) < 0

It means that:

sin(x) < 0

So, we have:

[tex]\sin(x) = -\sqrt{15/16[/tex]

Simplify

[tex]\sin(x) = \sqrt{15}/4[/tex]

sin(2x) is then calculated as:

[tex]\sin(2x) = 2\sin(x)\cos(x)[/tex]

So, we have:

[tex]\sin(2x) = -2 * \frac{\sqrt{15}}{4} * \frac 14[/tex]

This gives

[tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

Answers

Answer:

Explanation:

To simplify a polynomial, we have to do two things: 1) combine like terms, and 2) rearrange the terms so that they're written in descending order of exponent.

First, we combine like terms, which requires us to identify the terms that can be added or subtracted from each other. Like terms always have the same variable (with the same exponent) attached to them. For example, you can add 1 "x-squared" to 2 "x-squareds" and get 3 "x-squareds", but 1 "x-squared" plus an "x" can't be combined because they're not like terms.

Let's identify some like terms below.

f(x)=−4x+3x2−7+9x−12x2−5x4

Here you can see that -4x and 9x are like terms. When we combine (add) -4x and 9x, we get 5x. So let's write 5x instead:

f(x)=5x+3x2−7−12x2−5x4

Let's do the same thing with the x-squared terms:

f(x)=5x+3x2−7−12x2−5x4

f(x)=5x−9x2−7−5x4

Now there are no like terms left. Our last step is to organize the terms so that x is written in descending power:

f(x)=−5x4−9x2+5x−7

Step-by-step explanation:

−6x + 5y = 16x + 4y = −10

Addisonand Nolan are reading the same book. At the beginning of the month, Addison was on page 7 and Nolan was on page 47. Addison will read 11 pages per day and Nolan will read 6 pages per day. Let A represent the page of the book that Addison is on at the end of t days into the month, and let N represent the page of the book that Nolan is on at the end of t days into the month. Write an equation for each situation, in terms of t, and determine whether Addison or Nolan is farther along in the book after 4 days.

Answers

Answer:

A = 51 pages

N = 71 pages

Nolan will be 20 pages farther along in the book than Addison after 4 days.

Step-by-step explanation:

for Addison if you multiply 11 by 4 you get 44 then you add 7 you get 51

For Nolan if you multiply 6 by 4 you get 24 then you add 47 and you final answer is 71
