Hello can you guys please help me ? What is 4 over 5 but the answer has to be decimal I know what the answer is already it’s 0.8 but how can you get that please do it step by step and send a picture to I can see by the way it has to be in division thank you so much I really appreciate it.

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

step-by-step explanation:

d would equal 12

y-3=-3/2(x+4)

ur very much welcome
