Answer:

y = 1/2x + 3

Step-by-step explanation:

when X = 0, y = 3

when y = 0, 0 = kx + 3

For which equation will f(-2)= -6?

Mila [183]

Answer:

C. $f(x)=4x^3+6x^2-x$

Step-by-step explanation:

Lets plug in -2 into each of these equation to see which one gives us the solution of -6

A. $f(x)=x^3+x$

$f(-2)=(-2)^3+(-2)\\\\f(-2)=-8-2\\\\f(-2)=-10$

B. $f(x)=x^4-5x$

$f(-2)=(-2)^4-5(-2)\\\\f(-2)=16+10\\\\f(-2)=26$

C. $f(x)=4x^3+6x^2-x$

$f(-2)=4(-2)^3+6(-2)^2-(-2) \\\\f(-2)=4(-8)+6(4)+2\\\\f(-2)=-32+24+2\\\\f(-2)=-6$

D. $f(x)=-3x^3-4x^2+4x$

$f(-2)=-3(-2)^3-4(-2)^2+4(-2)\\\\f(-2)=-3(-8)-4(4)-8\\\\f(-2)=24-16-8\\\\f(-2)=0$

As we can see, function C was the only one that gave us the value of -6, so that is our answer.

Jeffery Apple orchard consist of two parcel of land. In one parcel, there are 28 rows of trees. Each row contains 32 trees. Jeff

Usimov [2.4K]

Answer:

Jeffery has 1,028 apple trees in his orchard

Step-by-step explanation:

In this question, we are asked to calculate the number of apple trees owned by Jeffery.

Firstly, we identify that Jeffery has an orchard containing 2 parcels of land.

In the first parcel of land, we have 28 rows of trees with 32 trees per row. The total number of trees here would be 28 * 32 = 896 trees

In the second parcel, there are 132 trees.

To get the total number of trees, we simply add the number of trees in the first parcel to the number of trees in the second.

Mathematically, that is 132 + 896 = 1,028 trees

Two of the most expensive cars in the world are car A and car B. The prices of these two cars differ by more than $15,000. The

Nadya [2.5K]

The possibilities of the price of car B are values greater than $146645 and values less than $116645

<h3>Write an absolute value inequality that describes this situation. Use x for the price of car B.</h3>

The price of car A is given as:

Car A = 131645

The price difference is given as;

Difference = 15000

The absolute value inequality is represented as:

|x - Car A| > Difference

So, we have:

|x - 131645| > 15000

Hence, the absolute value inequality is |x - 131645| > 15000

<h3>b. What are the possibilities for the price of car B?</h3>

In (a), we have:

|x - 131645| > 15000

Remove the absolute bracket

x - 131645 > 15000 and x - 131645 < -15000

Add 131645 to both sides of the inequality

x > 146645 and x < 116645

Hence, the possibilities of the price of car B are values greater than $146645 and values less than $116645
