Answer: Because we are trying to find the x-intercepts and the y-intercepts That would be (C)
Step-by-step explanation:
Self explanatory question, you set a quadratic equation to zero
For example: x 2 – 6 x = 16 equals to x 2 – 6 x – 16 = 0
Then, you would factor, that equals to (x – 8)( x + 2) = 0
(X-8)=0 (X+2)=0
X+2=0
-2 =-2
X=-2
X-8=0
+8 =+8
X=-8
To check you would simply plug in the values into the quadratic equation. They would both equal 16=16
:) Multiple choices are difficult but the best answers are C or D GO WITH YOUR GUT!
The number 2.85 can be writen using the fraction 285/100 which is equal to 57/20 when reduced to lowest terms.
It is also equal to 2 17/20 when writen as a mixed number.
You can use the following approximate value(s) for this number:57/20 =~ 2 6/7 (if you admit a error of 0.250627%)2.85 =~ 2 5/6 (if you admit a error of -0.584795%)2.85 =~ 3 (if you admit a error of 5.263158%)
The answer is 10 2/3 because if do
6 - 2/3 = 5 1/3 + 5 1/3 = 10 2/3.
Answer:
60.75
Step-by-step explanation:
sinA sinB
------- = -----
a b
sin(79)/9 = sinB/8
inverse sin B = 0.87
B = 60.75
