Okay so this used to confuse me when I was younger but It's actually pretty simple, just imagine the subtraction sign, the parentheses, and the negative sign in front of the two turns into a plus sign. It's basically addition with more steps so instead of seeing this - ( - you can see this +. I hope this helps.

The answer will bw 440.

Step-by-step explanation:

So what you do is rewrite...

330÷3/4

Then add a 1 at the bottom.

Then you need to divide, but to divide with the fraction you need to get the reciprocal.

330/1 multiply 4/3

And then you will need to simplify and then done.

Answer:

A. Lana saves at a greater rate because her unit rate of $50 per week is greater than Eliana's unit rate of $48 per week.

Step-by-step explanation:

Eliana​'s savings per week = the rate of change of the graph

The rate of change of the graph given = [tex] \frac{y_2 - y_1}{x_2 -x_1} [/tex]

Using the points (0, 0) and (2, 96),

Rate of change = [tex] \frac{96 - 0}{2 - 0} = \frac{96}{2} = 48 [/tex]

This rate of change means, Eliana puts $48 dollars per week into her account.

Since Lana's saving rate per week is $50, therefore:

Lana saves at a greater rate because her unit rate of ​$50 per week is greater than Eliana​'s unit rate of ​$48 per week.

Since Tim is looking at driving the car home with the smallest monthly payment. Which of the following statements is true?

a. The monthly payment for the loan is lower.

Let's understand what leasing is all about.

Leasing refers to the act of renting out an asset to someone after a contract outlining the terms has been agreed upon.

As a local dealer will be leasing out the car to Tim, Tim paying an additional $1,250 to cover the security deposit and the acquisition and documentation fees for the car will enable him get the car and go home with the smallest monthly payment.

The monthly payments on a lease are known to be usually lower. They are lower the monthly finance payments you spend on purchasing the same car. So, Tim getting the lease, he is actually paying to drive the car, and not actually to buy it.

Answer:

x=−10, 10, 3, −1

Step-by-step explanation:

The roots (zeros) are the x values where the graph intersects the x axis. To find the roots (zeros), replace y with 0 and solve for x.

The zeroes of the polynomial is (x+1) (x-3)(x+ 10) (x- 10).

The locations where a polynomial becomes zero overall are known as the zeros of the polynomial. The term "zero polynomial" refers to a polynomial with a value of zero (0). The highest power of the variable x is referred to as a polynomial's degree. A linear polynomial is a polynomial with degree 1.

By looking at the places on the graph where the graph line intersects the x-axis, one can determine a polynomial's zeros. The zeros of the polynomial are the x-coordinates of the sites where the graph crosses the x-axis.

Given:

[tex]x^4-2x^3-103x^2+200x+300[/tex]

Now, use root rational theorem

=(x+1) [tex]x^4-2x^3-103x^2+200x+300[/tex]/ (x+1)

Now, dividing

= [tex]x^4-2x^3-103x^2+200x+300[/tex]/ (x+1)

=  [tex]x^3-3x^2-100x+300[/tex]

Again,

= (x+1)( [tex]x^3-3x^2-100x+300[/tex])

= (x+1) (x-3)(x+ 10) (x- 10)

Hence, the zeroes of the polynomial is (x+1) (x-3)(x+ 10) (x- 10).

Step-by-step explanation:

If 875 were subtracted from each of the values in the data set the median of the set will be g - 875.

The median of the data is the value of the middle observation found after sorting the data in ascending order. In many cases, it is challenging to consider the entire data set as a representation; in these cases, the median is helpful. The median is a simple metric to calculate among statistical summary metrics.

Given The median of the values in a data set is g.

the median is calculated by,

Sort the information either in ascending or descending order.

Second, determine how many total observations there are, or n.

Verify the even/oddness of the number of observations, n.

let we have data set, a₁, a₂, a₃, a₄, a₅

for the set median is a₃,

and if 875 is subtracted from each digit

the set is a₁ - 875, a₂ - 875, a₃ - 875, a₄ - 875, a₅ - 875

the median is a₃ - 875,

similarly, the new median for the given set is g - 875.

Hence the median is g - 875.

Answer:

22

Step-by-step explanation:

First, find the equation of the line in slope-intercept form, y = mx + b.

Using the coordinates of these two pairs, (48, -30) and (61, -45), the slope (m) can be calculated as follows:

[tex] m = \frac{y_2 - y_2}{x_2 - x_1} = \frac{-45 -(-30)}{61 - 48} = \frac{-15}{13} [/tex]

[tex] slope (m) = -\frac{15}{13} [/tex]

Find the y-intercept (b) by substituting x = 48, y = -30, and [tex] m = -\frac{15}{13} [/tex] into y = mx + b:

[tex] -30 = -\frac{15}{13}(48) + b [/tex]

Solve for b.

[tex] -30 = -\frac{720}{13} + b [/tex]

Add [tex] -\frac{720}{13} [/tex] to both sides

[tex] -30 + \frac{720}{13} = b [/tex]

[tex] \frac{-390 + 720}{13} = b [/tex]

[tex] \frac{330}{13} = b [/tex]

[tex] b = \frac{330}{13} [/tex]

Substitute [tex] m = -\frac{15}{13} [/tex] and [tex] b = \frac{330}{13} [/tex] into y = mx + b

[tex] y = -\frac{15}{13}x + \frac{330}{13} [/tex]

The x-intercept of the line with the above equation, would be the value of x when y = 0. This is the value of x where the line cuts across the x-axis. To calculate this, substitute y = 0 into [tex] y = -\frac{15}{13}x + \frac{330}{13} [/tex].

[tex] 0 = -\frac{15}{13}x + \frac{330}{13} [/tex]

Subtract [tex] \frac{330}{13} [/tex] from both sides

[tex] -\frac{330}{13} = -\frac{15}{13}x [/tex]

Divide both sides by [tex] -\frac{13}{15}x [/tex]

[tex] \frac{-\frac{330}{13}}{-\frac{13}{15}} = x [/tex]

[tex] -\frac{330}{13}*-\frac{13}{15} = x [/tex]

[tex] -\frac{330}{1}*-\frac{1}{15} = x [/tex]

[tex] \frac{330}{15} = x [/tex]

[tex] 22 = x [/tex]

The x-intercept = 22
