What is the solution to the system of equations below?

x+y=7 and 3x-2y=11

a. (7 , 2)
b. (2, 7)
c. (4, 3)
d. (3, 4)

Answer: conversion factor is just how much of it is in another unit

Step-by-step explanation:

for example, 5280 feet are in a mile so the original rate of 15 in a hour can be turned into the equation on the first image.

Original rate (15 miles) x conversion factor (5280 feet are in a mile)

So when you multiple get 79,200 which simple means, in one hour she will go 79,200 ft. This concept can be applied to other scenarios such as feet and meter, liters and gallons, miles and kilometers, all that’s necessary is to know the conversion rate. The conversion factor is simple how much of your term is in another, this may be confusing but imagine it like this how many feet are in a yard? The answer is 3 so the conversion factor is just 3ft:1yd

Answer:

$79.30

Step-by-step explanation:

Initial sales price of scooter = $85.99

Sales tax rate = 8 1/2 or 8.5%

Discount rate = 15%

A 15% discount was given to Dante on the scooter i.e. 15% of selling price was taken off

We then calculate the discount amount : 15/100 × 85.99 = 12.8985

$12.8985 was reduced from the initial sales price= 85.99 - 12.8985 = 73.09

This means that $73.09 is the new sales price for the scooter

Sales tax is a compulsory amount charged by the government over every purchased good by a consumer. It is paid alongside the price for the good

Sales tax is calculated thus: Selling price × Sales tax rate

73.09 × 8.5/100 = 73.09 × 0.085

= 6.21

The Sales tax = $6.21

To calculate the total cost of the scooter = Sales tax + Selling price

6.21 + 73.09 = 79.30

Therefore, the amount in total that will be paid by Dante for the scooter is $79.30

Step-by-step explanation:

As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x. For example:

[-2.19] = -3

[3.67] = 3

[-0.83] = -1

The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on. This explains the domain and range relations of a step function.

This can be generalized as given below:

[x] = -2, -2 ≤ x < -1

[x] = -1, -1 ≤ x < 0

[x] = 0, 0 ≤ x < 1

[x] = 1, 1 ≤ x < 2

Answer:

b

Step-by-step explanation:

Answer:

Step-by-step explanation:

b=8

12x + b should be equivalent to 3(4x -5)

3(4x -5)

3 multiplied by 4x and -5 is

12x + -8

12x + b = 12x + -8,

therefore b = -8.

Answer:

(0,-4-4√6) and (0,-4+4√6)

Step-by-step explanation:

To determine the coordinates as Jon wants to place it 14 points away

√10^2+(a+4)^2 = 14

100+(a+4)^2 = 196

(a+4)^2 = 96

a+4 = ±√96

a+4 = ±4√6

a= -4±4√6

We can conclude that exists 211680 ways.

We know that the three research department is have 8, 10, and 7 members.

We choose a delegate and an alternate to represent the department.

First case: department have 8 members.

So, for a delegate, we have 8 options, and for a alternate 7, so a total of

\(8 \times 7 = 56 \ \text{options}\)

Second case: department have 10 members.

So, for a delegate, we have 10 options, and for a alternate 9, so a total of

\(10\times 9 =90 \ \text{options}\)

Third case: department have 7 members.

So, for a delegate, we have 7 options, and for a alternate 6, so a total of

\(7\times6 = 42 \ \text{options}\)

Therefore, we get:

\(56 \times 90 \times 42 = \bold{211680}\)

Hence, we conclude that exists 211680 ways.

Answer: Seki's interest rate for the bike is 33.33% each year; Seki will owe $8250 at the end of the loan.

Step-by-step explanation:

To calculate the simple interest rate, the equation is: r = (1/t)(A/P - 1)

Where:

r - interest rate per year (in decimal format)

t -time (loan time in years)

A - total accrued amount (initial price paid + amount of interest paid)

P - principle (initial price paid)

For this scenario:

r = (1 / 30)(8250 / 7500 - 1)

   - simplify both sets of parentheses: 1 / 30 and 8250 / 7500

r = (.033333)(1.1 - 1)

   - simplify the second set of parentheses

r = (0.033333) x 0.1

   - multiply

r = 0.0033333

   - convert r (as a decimal) to R (as a percentage) by multiplying r x 100

R = .3333

The interest rate on Seki's loan is 33.33%

The total amount Seki will pay:

equation for total due: A = P + I

Where:

A - total accrued amount (initial price paid + amount of interest paid)

P - principle (initial price paid)

I - amount paid in interest that accrued over time

For this scenario:

A = 7500 + 750

A = 8250

Seki will pay $8250 when the loan is due.
