The cost of 1000 bushels is $9790

Step-by-step explanation:

Given

$Cost = \$9.79$ per bushel

Required

Determine the cost of 1000 bushels

If 1 bushel costs $9.79,

Then 1000 costs:

$Total = \$9.79 * 1000$

$Total = \$9790$

(y - 2)2 = y2 – 6y + 4<br> Is this statement true or false?

trasher [3.6K]

<h3>Answer: False</h3>

==============================================

Explanation:

I'm assuming you meant to type out

(y-2)^2 = y^2-6y+4

This equation is not true for all real numbers because the left hand side expands out like so

(y-2)^2

(y-2)(y-2)

x(y-2) .... let x = y-2

xy-2x

y(x)-2(x)

y(y-2)-2(y-2) ... replace x with y-2

y^2-2y-2y+4

y^2-4y+4

So if the claim was (y-2)^2 = y^2-4y+4, then the claim would be true. However, the right hand side we're given doesn't match up with y^2-4y+4

--------------------------

Another approach is to pick some y value such as y = 2 to find that

(y-2)^2 = y^2-6y+4

(2-2)^2 = 2^2 - 6(2) + 4 .... plug in y = 2

0^2 = 2^2 - 6(2) + 4

0 = 4 - 6(2) + 4

0 = 4 - 12 + 4

0 = -4

We get a false statement. This is one counterexample showing the given equation is not true for all values of y.

Answer: (A)
Explanation: For there to be a solution at any one point, both inequalities must share a common point. This point will then satisfy both inequations, becoming a solution to both inequality.

Let's pick (A).
For there to be at least one solution, the first inequality must have a solution of $x \geq 3$ . Since the left side has clearly no points common to both graphs. Hence, no solution can exist that will satisfy both.

All of the other graphs have at least one point in common.
(B) has $x \leq -1$
(C) has $x = 1$
(D) has $x \leq -2$

You are hosting a party. You are providing 3 food items. Each guest brings 2 food items. Write an equation in two variables that

myrzilka [38]

Answer:

y = 3 + 2x

Step-by-step explanation:

Let y = Total number of food items

Let x = Number of guests

y = 3 + 2x

Example:

If there are 14 guests, we have:

y = 3 + 2(14)

y = 3 + 28

y = 31

So the equation gives us a total number of 31 food items from both you and the guests.
