Answer:
Step-by-step explanation:
You need at least $90 dollars, so x will be bigger than or equal to that amount.
Your parents don't want to give you more than $150 dollars so x is smaller than or equal to that amount.
Answer:
and .
Step-by-step explanation:
The equation can be simplified with the help of trigonometric identities:
Which means that equation is equal to zero if any component of the product is zero. The solutions of the expression are:
a)
b)
Any value different of both subsets do not satisfy the equation described above.
29.) This is simply interpreting the linear function.
The function:
96+2.1x
a.) The 96 is what you start with from the beginning. So, we know Rachel weighed 96 ounces when she was born.
b.) Again, interpretation. The 2.1 is the slope, or the change in the line. So we know that Rachel gains 2.1 ounces each day.
30.) For this one, you just have to plug 9 into the equation for x.
Answer:
x=2
Step-by-step explanation:
F(x) = 2x^2 - 8x +8
Axis of symmetry lies at the x coordinate of vertex
To find x coordinate of vertex use formula
from the given f(x) , a= 2 and b = -8
Plug in all the values
x=2
So the axis of symmetry at x=2
Answer:
B
Step-by-step explanation:
Isolate a
f = m × a
divide m from both sides
f/m = a
