Use the equation below to find y, if m=4, x = 3, and b=11

Afina-wow [57]

Answer:

y = 23

Step-by-step explanation:

Assuming the equation not below is y = mx + b form...

m = 4

x = 3

b = 11

y = 4(3) + 11

y = 12+ 11

y = 23

A store charges $13.75 for 5 boxes of cookies. A second store charges $9.00 for 4 boxes of cookies, but you have to buy a gal

belka [17]

Answer: The number of boxes of cookies that makes the costs equal is 3

Step-by-step explanation:

A store charges $13.75 for 5 boxes of cookies. This means the charge per cookie is 13.75/5 = $2.75

Therefore, for x cookies, the store charges 2.75 × x = $2.75x

A second store charges $9.00 for 4 boxes of cookies. This means the charge per cookie is 9/4 = $2.25

Therefore, for x cookies, the store charges 2.25 × x = $2.25x but you have to buy a gallon of milk for $1.50 to get that deal.

This means that at the second store, the charge for x cookies will be

2.25x + 1.50. Therefore, the cost model equations for both boxes are

Cost of x boxes cookies at first store, C(x)= $2.75x

Cost of x boxes of cookies at second store, C(x) = 2.25x + 1.50

To find number of boxes of cookies that make both costs equal,

2.75x = 2.25x + 1.50

2.75x - 2.25x = 1.50

0.5x = 1.5

x = 1.5/0.5 = 3

Given the function f ( x ) = 4 x 2 − 5 x + 7 f ( x ) = 4 x 2 - 5 x + 7 . Calculate the following values: f ( − 2 ) = f ( - 2 ) =

qaws [65]

Given the function f(x) = 4x² - 5x + 7, the output values of f(-2), f(-1), f(0), f(1) and f(2) are 33, 16, 7, 6 and 13 respectively.

<h3>What are the output values of the given numbers in the function?</h3>

Given the function is the question;

f(x) = 4x² - 5x + 7

f(-2) = ?

f(-1) = ?

f(0) = ?

f(1) = ?

f(2) = ?

To determine the output value of f(-2), replace all occurrence of x with -2 in the function and simplify.

f(x) = 4x² - 5 x + 7

f(-2) = 4(-2)² - 5(-2) + 7

f(-2) = 4×4 + 10 + 7

f(-2) = 16 + 10 + 7

f(-2) = 33

To determine the output value of f(-1), replace all occurrence of x with -1 in the function and simplify.

f(x) = 4x² - 5 x + 7

f(-1) = 4(-1)² - 5(-1) + 7

f(-1) = 4×1 + 5 + 7

f(-1) = 4 + 5 + 7

f(-1) = 16

To determine the output value of f(0), replace all occurrence of x with 0 in the function and simplify.

f(x) = 4x² - 5 x + 7

f(0) = 4(0)² - 5(0) + 7

f(0) = 0 + 0 + 7

f(0) = 7

To determine the output value of f(1), replace all occurrence of x with 1 in the function and simplify.

f(x) = 4x² - 5 x + 7

f(1) = 4(1)² - 5(1) + 7

f(1) = 4×1 - 5 + 7

f(1) = 4 - 5 + 7

f(1) = 6

To determine the output value of f(2), replace all occurrence of x with 2 in the function and simplify.

f(x) = 4x² - 5 x + 7

f(2) = 4(2)² - 5(2) + 7

f(2) = 4×4 - 10 + 7

f(2) = 16 - 10 + 7

f(2) = 13

Given the function f(x) = 4x² - 5x + 7, the output values of f(-2), f(-1), f(0), f(1) and f(2) are 33, 16, 7, 6 and 13 respectively.

Two cargo ships are sailing a direct course into harbor. Ship A is 22 miles from harbor. Ship Bis sailing into harbor on a cours

s344n2d4d5 [400]

Answer:

The distance of ship B from the Harbor is 32.26 miles

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.

I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the <u>COSINE operator</u> to solve for the length of the course of ship B.

$cos(x) = \frac{adjacent}{hypotenuse}$
