Would this be y = x^2 - 3 since the curve is pointing down instead of up?

Since the parabola is opening upwards it has to be positive. The equation you said it might be is wrong b/c then the parabola would open downwards. the answer is y=x^2+3. And you can use this website for graphing it will help. it helps me.

Answer:

I believe it's B

Step-by-step explanation:

Isosceles triangles have congruent base angles, so base angle A and B should both be the same number. (25)

Added up, 25+25+130 is 180 degrees.

This is a k 12 question

kompoz [17]

Total is 45-5 = 40, because it starts at 5, tricky haha

Area in interest is 30-20 = 10

What percentage is 10 of 40?

10/40 = 0.25

0.25*100 = 25%

This year, The Lexington Times had 12,698 subscribers. That is 40% more than they had last year before the paper was bought out.

Answer:

They had 7,618.8 subscribers last year.

Let me know if this helped :)

Step-by-step explanation:

We need to find 40% of 12,698

To do that, we need to multiply 12,698 by the decimal form of 40%.

12,698*0.40=5,079.2

Then, we need to subtract 5,079.2 from the amount of subscribers we had this year.

12,698-5,079.2= 7,618.8

Answer:

13. 0

14. 4

15. 0

*12. 10

Step-by-step explanation:

Given values of each variable:

n = 2

q = -1.5

r = -3

v = -8

w = 4.5

x = 4

Since all variables' values are given, the process of simplification is simple:

13:

|-2x + 5n| + (n-x) First, plug in all known values.

|-2(4) + 5(2)| + (2 - 4) Simplify the expressions in each of the parentheses.

|-8 + 10| + (-2) Add -- Addition of a negative is subtraction.

|2| - 2 The absolute value of 2 is 2.

2 - 2 Subtract.

14:

4w - |2r + v| First, plug in all known values.

4(4.5) - |2(-3) + (-8)| Simplify the expressions in each of the parentheses.

18 - |-6 - 8| Subtract the values in the parentheses.

18 - |-14| The absolute value of -14 is 14.

18 - 14 Subtract.

15:

3|w - n| - 5|q - r| First, distribute the 3 and 5.

|3w - 3n| - |5q - 5r| Plug in all known values.

|3(4.5) - 3(2)| - |5(-1.5) - 5(-3)| Distribute--Subtraction of a negative is addition.

|13.5 - 6| - |-7.5 + 15| Simplify the expressions in each of the parentheses.

|7.5| - |7.5| The absolute value of 7.5 is 7.5.

7.5 - 7.5 Subtract.

8. - 11. are correct. However, 12. is 10 because you need to distribute before simplifying what's in the parentheses.
