Yep i need lol i’m bad at number lines like really bad

2 1/4

Step-by-step explanation:

It is asking you to find how many pounds she has all together. First I would add all the 1/4, there are 5 1/4 Xs so that equals 1 1/4. Then i would find how many 1/2 Xs there are, here there are two, this is very good because if you have two halves it makes one whole, so it equals 1. Last you add them both together, so 1 1/4 + 1, this equals 2 1/4.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

i believe that the slope of the line is -5
