How do you find the correct equation? Follow these steps.
First, plug 0 in for X and solve for Y . Does the y value match what is on the graph? 0 in this case?
a. 0 = -2(0) True - This could be an answer
b. 0 = 0 + 4 False - This cannot be an answer
c. 0 = 2(0) True - This could be an answer
d. 0 = 0 - 4 False - This cannot be an answer
Now we are down to 2 possible answers A and C. Now take another point on the line, say x=-2 and repeat, does the answer match what is on the graph? (4).
a. 4 = -2(-2) True
c. 4 = 2(-2) False
As only A matches, A must be the answer. With graphing problems, when you have to find the correct equation, always choose X=0 as the first point (assuming it has a Y value) and eliminate answers. I hope this helps.
Answer:
Step-by-step explanation:
If you use the triangle inequality theorem you just add the first two sides to determine if the number is bigger than the third side if so it can form a triangle that's the first step. Just repeat with a b and c a+b a+c and b+c, and it will help you determine what type of triangle it is.
I believe the first set can, angle a and c are larger than angle b I can't be sure about the other one. I'm sorry I hope this helps push you some direction forward.
Answer:
1. 9 or -9
2. 3.6 or -3.6
3. 12 and -12
4. The quadratic function has no real roots.
Step-by-step explanation:
1. Solve x² -81 = 0
x² -81 = 0
x² = 81
x = ±√81
x = 9 or x = -9
2. solve 2x² - 26 = 0
2x² - 26 = 0
2x² = 26
x² = 13
x = ±√13
∴ x = 3.6 or x = -3.6
3. f(x) = x² - 144
let f(x) = 0
x² - 144 = 0
x² = 144
x = ±√144
x = 12 and x = -12
4. f(x) = x² + 25
let f(x) = 0
x² + 25 = 0
x² = -25
x = ±√(-25)
There is no square root of a negative number. Its square is not a real number.
Answer:
Diameter of the wheel = 1.2 feet
Step-by-step explanation:
Radius of a wheel = Distance between a point on the circumference and the center of the circle
Diameter of a wheel = 2(radius of the circle)
= 2(0.6)
= 1.2 feet
Therefore, diameter of the wheel is 1.2 feet.
Okay, so first of all, if the trapezoid was translated right 4,
Then all the (x)'s should be 4 more than the original value
For example: (2,-3) <span>→ (6,-3)
Now since the Trapezoid was translated down 3,
Then all the (y)'s should be 3 less than the original value
For example: (2,-3) </span><span>→ (2,-6)
Now do this to all the Vertices
