Answer:
vertex form
Step-by-step explanation:
y= -3(x-5)^2+7
This equation is written in vertex form
y = a(x-h)^2 +k
The vertex is (h,k)
Answer:
<h2><u>Required</u><u> Answer</u><u> </u><u>:</u><u>-</u></h2>
Ratio = Width: Height
Ratio = 720 : 540
Cancelling 0
Ratio = 72 : 54
Cancelling by 9
Ratio = 8 : 6
Cancelling be 2
Ratio = 4 : 3
Answer:
A = -9, B = 65
Step-by-step explanation:
Take the square root of both sides of the equation:
h + 9 = ±√65
Subtract 9 from both sides of the equation:
h = -9 ± √65
Comparing this to the form
h = A ± √B
we see that A = -9 and B = 65.
_____
A lot of math is about matching patterns of numbers and variables. Here, you're asked to match the expression -9±√65 to the pattern A±√B and identify the values for A and B that make these expressions identical.
It should not be difficult to see that the stuff on the left side of ± is the value of A. That stuff is -9.
The stuff under the radical is the value of B. That stuff is 65.
Answer:
<h2>The domain: all real numbers</h2>
Step-by-step explanation:
f(x) = 3|x + 4| + 1
We can substitute any real number for x and each operation will be executable.
Absolute value of any number exists. Therefore x ∈ R.
