Answer:
A.) 40°
Step-by-step explanation:
A triangle is equal to 180°
Angle X and Y has the same angle, so both have 70°.
So:
70° × 2= 140°
To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.
So:
180° - 140°= 40°
Answer= 40°
I hope this helps! :)
X²>49
well, I don't know a formula but this is how I would solve it
I first solve x²=49 to obtain x=+/-7
so then would it be x>+/-7?
if we try 8 it works
if we try -9 it works
so answer is x>+/-7
basically x<-7 or x>7
The cube is rolled there is a 3/6 percent chance it will land on 2. But since there are only for spins it is a 2/4 which is the same thing as 3/6 so it will be a equal percent chance that it will land on 2 as the same for the other numbers.
Answer: yes, they are congruent they are just rotated
Step-by-step explanation:
Answer:
C) [-4,0)
Step-by-step explanation:
Look at the endpoints. You have (-3,0) which isn't included in the function and you have (1,-4) which is included in the function.
We use interval notation when we are describing the subset of numbers in a function by using parentheses to show an endpoint is not included and brackets to show an endpoint is included.
In this case, since we are being asked to find the range of the function, that only pertains to y-coordinates.
Given that (1,-4) is included in the function, this means that y=-4 is included in the function. Therefore the answer's interval notation will start with a bracket to show it's included.
Given that (-3,0) isn't included in the function, this means that y=0 isn't included in the function. Therefore the answer's interval notation will end with a parenthesis to show it's not included.
Combining the two elements, we have an interval notation of [-4,0) which means C is the correct answer
