Me with this. 20 points.
relationship b has a greater rate than relationship a. this graph represents relationship a.
which equations could represent relationship b?
select each correct answer.
a. y = 1.4x
b. y = 3x
c. y=12x
d. y = 2.2x

i think D

Step-by-step explanation:

why

As the graph is basically  y = 2x then all the answer with a higher slope are meant to be equations that represet relationship B. So the answers will be the second one: y=2.2x and the fourth one y= 3x

i need a picture or some numbers

step-by-step explanation:

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
