Answer:

when x = 4 ======> y = 1

when y = 6 =======> y =9

Step-by-step explanation:

Given that:

4y-4x=-12

First put x = 4

4y - 4(4) = -12

4y - 16 = -12

4y = -12 + 16

4y = 4

Dividing both sides by 4

y = 1

Now put x = 6

4y-4x=-12

4y - 4(6) = 12

4y - 24 = 12

4y = 12 + 24

4y = 36

Dividing both sides by 4

y = 9

So when x = 4 ======> y = 1

when y = 6 =======> y =9

i hope it will help you!

Write a function in terms of t that represents the situation.

elena55 [62]

Answer:

4.5(1.035)^t

Step-by-step explanation:

An inrease of 3.5% means that each year's total is 103.5% of the year before, right?

Year 1 = 4.5(1.035) = 4.66

Year 2 = 4.66(1.035) = 4.82

etc.

So, year 2 is 4.5(1.035)(1.035) = 4.82

Multiplying something by itself can be written with an exponent instead, so 2 years is...

4.5(1.035)2

Since the number of years is the variable (let's call it t)...

Calculate the volume of the cylinder, where a = 18 and b = 11. Use 3.14 for pi and round your answer to the nearest tenth.

cupoosta [38]

Answer:

Volume of cylinder $=2797.7$

Step-by-step explanation:

Let $a$ be diameter and $b$ the height of the cylinder

$Then\ radius(r)=\frac{diamater\ (a)}{2}\\\\r=\frac{18}{2}\\\\r=9$

Volume of cylinder $=\pi\times(radius)^2\times(height)$

$=\pi\times(9)^2\times11\ \ \ \ \ \ (\pi=3.14)\\\\=3.14\times9\times9\times11\\\\=2797.74\\\\\approx2797.7$

A grocery store manager must decide how to best present a limited supply of milk and cookies to its customers. Milk can be sold

miss Akunina [59]

Answer:

Option A.

Step-by-step explanation:

Let M be the milk per gallon.

C be the cookies per dozen.

B be the bundle (one gallon of milk and a dozen cookies ).

Milk can be sold by itself for a profit of $1.50 per gallon. Cookies can likewise be sold at a profit of $2.50 per dozen and bundle is sold for a profit of $3.00 per bundle.

$Profit= 1.5M + 2.5C + 3B$

We need to maximize the profits. So, our objective function is

Therefore, the correct option is A.
