Answer:
D
Step-by-step explanation:
Given y varies directly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 
when x = 1 and z = 4 , then
= k × 1 × 4 = 4k ( divide both sides by 4 )
= k
y = xz ← equation of variation
When x = 6 and z = 3 , then
y = × 6 × 3 = × 18 = 2 × 6 = 12
Answer:
5 + - 6
Step-by-step explanation:
Note a + (- b) = a - b, thus
5 + - 6 = 5 - 6 = - 1 < 0
Thus is a counter example to the sum of 2 numbers ≥ 0
Answer:
D. 130
Step-by-step explanation:
The lines are tangent to the circle therefore 90º which makes 65º + 25º. The small triangle with C is iso so the angle of C would be 130 and equivalent to x
Answer:
109 degrees is the answer
Answer:
24
Step-by-step explanation:
When there are two lines beside a number like |24|, it is asking for us to determine the distance between the number and 0 on a number line. This is called finding the <em>absolute value</em>.
The absolute values of all numbers are equal to themselves, and it will always be a positive number (ex. |-8| = 8).
Knowing this, the absolute value of 24, or |24|, is equal to 24.
I hope this helps!
