Answer:
m < -4 or m > 4
Step-by-step explanation:
B² - 4ac > 0
m² - 4(1)(4) > 0
Roots are 4, -4
m < -4 or m > 4
Answer:
parent function is the simplest function that still satisfies the definition of a certain type of function. For example, when we think of the linear functions which make up a family of functions, the parent function would be y = x. This is the simplest linear function.
The parent function of a square root function is y = √x
1. x = 22, 2. x = 1, 3. x = 10
1.
2x - 28 = 16 ( add 28 to both sides )
2x = 44 ( divide both sides by 2 )
x = 22 ← solution
2.
12 = 5x + 7 ( subtract 7 from both sides )
5 = 5x ( divide both sides by 5 )
1 = x ⇒ x = 1 ← solution
3.
140 = 10x + 4x ( collect like terms on right side )
140 = 14x ( divide both sides by 14 )
10 = x ⇒ x = 10 ← solution
3y - yz = 2z
First separate y from 3y - yz = 2z
3y - yz is the same as y * (3 - z) so...
y (3 - z) = 2z
Now divide both sides by (3 - z)
y = 2z / (3 - z)
The answer is y = 2z / (3 - z), the answer you stated is correct except at the end, it isn't - 2, but - z, and also you should include parenthesis around it. Found this helpful? Give it a Brainiest reward if so.
