Answer:
x = 81, y = 68, z = 99
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left, then
x = 180 - (36 + 63) = 180 - 99 = 81
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle on the right, thus
13 + y = x , that is
13 + y = 81 ( subtract 13 from both sides )
y = 68
Consider the triangle on the right
z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99
Answer: 34
f(-2) means inserting 'x = -2' into the equation.
x = -2
4*|-2 -4| +2
= 4*|-8| + 2
= 4*8 + 2
= 32 + 2
= 34
Answer:
A
Step-by-step explanation:
sqrt(x) ≤1
Square each side
x ≤1
But we have to look at the limit on the square root
We know that square root must be greater than or equal to zero so x ≥0
0 ≤x ≤1
Answer:
Step-by-step explanation:
f(x)=3x-12
f ' (x) = 3x^0 - 0
when you differentiate, you lower the power by one, and multiply the coeffiecient by the original power for 3x in this case we multiply 3 by 1 and lower the power of x to zero, so the x goes away. and the derivative of any constant, in this case 12, is always 0
