You see if the graphs passes the vertical line test.
if any vertical line passes through more than one part of the graph then its not a function - just a relation.
Answer:
∠c = 33°
∠b= 147°
Step-by-step explanation:
A line is 180°, and ∠c + 147° make up a linear pair.
180 - 147 = 33°
∠c is 33°.
∠b and 147° angle are vertical angles, meaning that they have the same angle measure.
∠b = 147°.
Answer:
E and F= 54 Degrees D is 90 degrees
Step-by-step explanation:
The answer is c.0.1,0.05.0.025.
We can find these by substituting the x values on the table given into the equation; h(x)=1/x.
Answer:
x = ±5
Step-by-step explanation:
4x^2 = 100
Divide each side by 4
4/4x^2 = 100/4
x^2 = 25
Take the square root of each side
sqrt(x^2) = ±sqrt(25)
x = ±5
