we can write  (x+6)(x-3)=0  , x²+6x-3x-18=0,  y=x²+3x-18 
check y int =-18 on the graph
y=1x²+3x-18

Which statement best describes how to determine whether f(x)=9-4x^2 is an odd function
satela [25.4K]
If you want to know if a function is odd, you look at the exponents/degrees it has; if they're all even it's an even function if they're all odd it's an odd function if it has a mix of both even and odd its neither
the function 9-4x^2 only has one x with an exponent of two making it even

jekas [21]

Answer:

D

Step-by-step explanation:

1.8 is the greatest number and then you have the choice between -66% or -1/3 as the second greatest number. lets convert them into decimals so your looking at them all the same. -1/3 is -.3333( repeating). -66% is -.66. So that would mean that -1/3 is the greater number.

When 7 is subtracted from five times a number, the result is greater than twice the sum of the number and 4. Find all the number
hichkok12 [17]

Given :

When 7 is subtracted from five times a number, the result is greater than twice the sum of the number and 4.

To Find :

All the numbers that satisfy the inequality.

Solution :

Let , the number is x .

Mathematical expression for first term is :

5x - 7

Mathematical expression for second term is :

2(x + 4)

Now , comparing both the expression by given constrain.

5x - 7 > 2(x + 4)\\\\5x-7>2x+8\\\\3x>15\\\\x>5

So, all the numbers that satisfy the inequality are greater than 5.

Hence , this is the required solution.
