D. - 3k² – 2k+7 + K-2

Mathematics
1 answer:
11Alexandr11 [23.1K]2 years ago
8 0

Answer:

 3k2 - k + 5

just add all of the variables or minus all of the variables and if u can add the non-variable numbers but if a variable has exponent add it with the <u>same </u>type of variable exponent so in this case 3k squared doesn't get added to anything so it just stays 3k2 and -2k gets added to k which equals -k cause -2k is bigger than k and if the bigger number is negative in any equation stays negative. Then u just add all the numbers which would be 7+-2 which would equal five.

Hope this helped

jek_recluse [69]

Answer:

64 softballs

Coach Beard currently already has 24 softballs.

When she orders 2 more buckets with 20 in each, that's another 20 + 20 = 40 softballs added to the original 24. So, let's add these two numbers:

24 + 40 = 64

Which quadratic equation is equivalent to (x^2-1)^2-11(x^2-1)+24=0
Y_Kistochka [10]

Answer:

The correct answer is first option

u² - 11u + 24 = 0

When u = (x² - 1)

Step-by-step explanation:

It is given that,

(x² - 1)² - (x² - 1) + 24 = 0

<u>To find the correct answer</u>

Substitute u = x² - 1

The equation becomes,

u² - 11u + 24 = 0 Where u = (x² - 1)

Therefore the correct answer is first option

u² - 11u + 24 = 0

When u = (x² - 1)

A.) a right triangle would have 2 acute angles.
b.) there would be 0 obtuse angles.
c.) there would be 1 right angle.

In the diagram you can see a little black box in one of the corners of the triangles. That box means the angle is a right, 90 degree angle. Since an acute angle is an angle that is less than 90 degrees, and since all three angles would have to add up to 180 degrees, you know that the other two angles are acute angles.

The equation illustrated shows that the gross pay will be $97.

<h3>How to compute the value?</h3>

It should be noted that she earns an hourly rate of $17.15 and receives time and a half for overtime. The number of hours will be 3 hours 35 minutes at first. This will be:

= (17.15 × 3.58)

= 61.5

The amount for overtime will be:

= (1/2 × 17.15) × 4.5

= 35.59

The Total amount will be:

= 61.5 + 35.59

= $97

The graph shows the cost of grapes at a grocery store. What is the slope of the line?
Marysya12 [62]

The slope of the line shown in the graph is 4.5 .

In the question ,

it is given that ,

the amount of grapes is represented on x axis . and

the cost for that grape in the grocery store is represented on y axis .

to find the slope we need two points on the line ,

from the graph we can take two points as (1 , 4.5) and (2 , 9) ,

the slope can be calculated using the formula

slope = (change in y coordinate)/(change in x coordinate)

slope = (9 - 4.5)/(2 - 1)

slope = 4.5/1

slope = 4.5 .

Therefore , The slope of the line shown in the graph is 4.5 .

The given question is incomplete , the complete question is
