Let m=x^2-5m=x 2 −5m, equals, x, squared, minus, 5. Which equation is equivalent to (x^2-5)^2-3x^2+15=-2(x 2 −5) 2 −3x 2 +15=−2l
adelina 88 [10]

Answer:

  • m^2-3m=-2
  • m^2-3m+2=0

Step-by-step explanation:

Let m=x^2-5

We want to express the equation (x^2-5)^2-3x^2+15=-2 in terms of m.

Given: (x^2-5)^2-3x^2+15=-2

Factorizing the third and fourth term, we obtain:

(x^2-5)^2-3(x^2-5)=-2

Substituting  m=x^2-5, the above equation becomes:

m^2-3m=-2

Since the options are not given, the equivalent equation is:

m^2-3m=-2

It could also be written in a rearranged form as:

m^2-3m+2=0

If y = 3x - 4 and the domain is {-3,-1,4}, find the range.
GREYUIT [131]
We could put the domain into the x values to get the y values (range). 

y = 3(-3) - 4
y = -9 - 4
y = -13

y = 3(-1) - 4
y = -3 - 4
y = -7

y = 3(4) - 4
y = 12 - 4
y = 8
