Answer:

1. Sean

2. Mariana

Equations:

Sean: y=-5.5x+300

Mariana: t=-5x+250

For the first question, it is basically asking for who has a greater negative slope, which would be Sean, since he drank his faster.

For the second question, Mariana finished his slushy at the x-intercept of 50, while for Sean, it would be an estimated 54.5.

I need to solve this system of equations, how do I do that?<br> 3x-4y=20<br> y=3/4x-5
Paha777 [63]

Answer:

Is is Infinitely many solutions so 0=0

<em><u>Step-by-step explanation:</u></em>

<h3>First we have to rearrange/simplify the equations:</h3>

Equation 1: 4y - 3x = -20

Equation (2):  y - 3x/4  = -5

<h3>Then you remove the fractions by multiplication: </h3>

Multiply equation (2) by 4

<h3>The Equations now look like this: </h3>

Equation 1: 4y - 3x = -20

Equation (2): 4y - 3x = -20

<h3>Solve for y on Equation (2):</h3>

y = <u><em>3x/4 - 5</em></u>

<h3>Then plug in this for the y in Equation 1 and then solve:</h3>

4•(<u><em>3x/4-5</em></u>) - 3x = -20

Therefore the answer leads to:

Infinitely many solutions, 0=0

Hope this helped :')

Lucas borrows $3,500 at 2% for 6 years. How much does he have to repay at the end of the loan total?
drek231 [11]

Answer:

$3941.57.

Step-by-step explanation:

Given,

Principal,P = $3,500

rate of interest,r = 2%

Time, n = 6 years

Now, the total amount Luca has to repay is:

A = P(1+\frac{r}{100})^n

A is the total amount.

A = 3500\times (1+\frac{2}{100})^6\\A = $3941.57

Hence, the total money he has to repay is $3941.57.

6. Determine the number of solutions for each of the equations below. Be sure to
Jlenok [28]

Answer:

<h3>C. no solution</h3>

Step-by-step explanation:

Determine the number of solutions for each of the equations below. Be sure to

justify your conclusions. *

(z – 8)2 = -1

A. one solution

B. infinitely many solutions

C.no solution

D. x = 9

Given the expression;

<u>(z – 8)^2 = -1</u>

we are to find the nature of the solution;

Take the square root of both sides

(z – 8)^2 = -1

√(z – 8)^2 = √-1

z- 8 = √-1

Note that √-1 will give a complex number i to have;

z = 8 ± i

This therefore shows that the equation has no real solution.
