Which is the simplified form of the following expression? 7x - 9y + 4x^2 - 2x + 12y


A. 13x + 3y

B. 11x + 21y

C. 4x2 + 5x + 3y

D. 4x2 + 9x + 21y

Answers

Answer 1

i think its c because 7x-2x is 5x, -9y + 12y is 3y, and 4x^2 stays the same

Answer 2
Rearrange it so the x is on the left and y is on the right starting with the highest x value which is x^2

4x^2 + 7x - 2x - 9y + 12y
= 4x^2 + 5x + 3y

There the answers is C.

Answers

Answer:

summary

Step-by-step explanation:

Answer: Choice C

To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)

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

Explanation:

The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.

The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,

slope = rise/run = (change in y)/(change in x)

Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.

What is the circumference of Circle O?

Answers

Answer:

[tex]14\pi[/tex]

Step-by-step explanation:

The formula for finding the circumference of a circle is 2 times pi times the radius.

Looking at the picture, we can see that the radius of the circle is 7 cm. Plugging that into the formula gives:

2*[tex]\pi[/tex]*7 = 14[tex]\pi[/tex]

Answer: 14π cm or 43.98 cm.

Step-by-step explanation: To find circumference, one must use the equation c = 2πr (c = circumference and r = radius). Plugging in the values, we get 2πr = 2*π*7 which = 14π or if you want it rounded: 43.98 cm.

Kimi’s dog gives birth to a litter of 4 puppies per year, on average. The relationship between time and the expected total number of puppies is shown on the graph. Which other ordered pairs would fall on this line? Select all that apply.
(0, 0)
(2, 6)
(3, 12)
(4, 14)

Answers

Answer:

(0,0) and (3,12)

Step-by-step explanation:

The ordered pairs that would fall on the line are (0, 0), (1, 4), (2, 8), (3, 12), and (4, 16).

As shown in the graph,

x-axis represents the number of years

y-axis represents the number of puppies.

The slope of the line is 4, which means that for every 1 year that passes, the number of puppies increases by 4.

The y-intercept of the line is 0, which means that if there are 0 years, then there are 0 puppies.

The ordered pairs (2, 6) and (4, 14) do not fall on the line because they do not follow the slope of the line.

For example, in the case of (2, 6), the number of puppies should be 8, not 6.

Therefore, the only ordered pairs that would fall on the line are (0, 0), (1, 4), (3, 12), and (4, 16).
