Answer:
y = 49
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 21 when x = 6 , then
21 = 6k ( divide both sides by 6 )
3.5 = k
y = 3.5x ← equation of variation
When x = 14 , then
y = 3.5 × 14 = 49
Answer:
x=0;y=-2
Step-by-step explanation:
multiply first equation by 6: 18x-24y=48
Subtract 2nd equation from 1st: -19y=38
y=-2
Sub into 1st equation: 3x-4(-2)=8
3x+8=8
3x=0
Therefore, x=0;y=-2
Answer:
D)5/11
Step-by-step explanation:
So yeah there's 22 balls in total!
Then for the red balls, there are the balls numbered evenly: 6, 8, 10, 12, 14. So there's 5 even balls for red.
Then for the green balls: 8, 10, 12, 14, 16, there are also 5!
5+5=10
10/22
=5/11
The answer is D!

Answer:
12.0 cm
Step-by-step explanation:
The Pythagorean theorem applies:
(12 cm)² +b² = (17 cm)²
b² = (289 -144) cm² = 145 cm²
b = √145 cm ≈ 12.04 cm
b ≈ 12.0 cm . . . . rounded to 1 decimal place
I would say 4^0 would be the best answer
