Writing equations of each line Pass through (1,5) and (3,11)

1 answer:

3 0

To answer this problem, first use the equation y=mx+b by plugging in your point, (3,11) for x,y and using the slope formula to find m. (11-5)/(3-1)= 3. So, you would get 11= 3x3 +b, which can be simplified to b=2. So, your final equation is y=3x+2

One of the giraffes, Bernard, is sick. Last week he weighed 2,490 pounds. This week he weighs 2,312 pounds. If w represents the

victus00 [196]

Answer:

$w+2,312=2,490$

$w=178\ pounds$

Step-by-step explanation:

Let

w ----> the amount of weight lost in pounds

we know that

The amount of weight Bernard lost plus the weight of this week must be equal to the weight of the last week

The linear equation that represent this situation is

$w+2,312=2,490$

solve for w

subtract 2,312 both sides

$w=2,490- 2,312=178\ pounds$

The second option is the correct answer

$16x^{4}+40x^{3} -24x^{2}$

The expression given to us is:

$8x^{2} (5x+2x^{2}-3 )$

Herein, we can simplify it by opening up the bracket and multiplying each term inside the bracket by the term which is outside the bracket.

Thus, we get:

$8x^{2} (5x+2x^{2}-3 )=8*5x^{2+1} +8*2x^{2+2}-8*3x^{2}$

$40x^{3} +16x^{4}-24x^{2}$

Rearranging the above expression in descending order of power we get:

$16x^{4}+40x^{3} -24x^{2}$

From the given options we can see this is the second option. Hence the second option is the correct answer.

Find the product? I’m in desperate need of a little help.

Unsure of what you want.

If you are merely to mult. the 3x3 matrix by -8, then mult. every one of the 9 elements in the first matrix by -8. That's it.

If there was more to this problem, please share the instructions.
