Hi there! :) The answer to your question is 3. First you do parenthesis r=3.
3+7=10, then you do 10*2=20. That is how you solve the problem.

Hope I helped! :)
( Mark as Brainliest Answer! Thank you! :)

20 = 2(r + 7)
20/2 = r + 7
10 = r + 7
10 - 7 = r
3 = r
r = 3

The answer is: r = 3.

Here you have to divide the amount of poppies by the people so 2148÷2000=10.74 but you would want to round down to 10 since you cant give a person 10.74 of a flower.

Which equation has a graph that is a parabola with a vertex at (-1, -1)?ОООО
O y = (x - 1)2 + 1
y = (x - 1)2 - 1
y = (x + 1)2 + 1
· y = (x + 1)2 - 1

Answers

Answer:

y = (x + 1)² - 1

Step-by-step explanation:

The equation of a parabola in vertex form is:

y = a(x - h)² + k

where the vertex is located at (h,k). Replacing with vertex at (-1, -1) we get:

y = a(x - (-1))² + (-1)

y = a(x + 1)² - 1

The only option with vertex at (-1, -1) is y = (x + 1)² - 1 (where a = 1)
