Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
1 and 8 should be the answer I believe.
You need to add 3 and 8 and since 8 belongs to soccer it's going to be 8/11 multiplied by 132 and it gonna give you 96(answer)
Well to find the value of x you need to get x alone. so you -1 from 3 and do 2/27 and your answer is 0.074
Answer:
3.5 m/hr
Step-by-step explanation:
2 + c = 5 -c c = speed of current
2 c = 3 c = current speed = 1.5 m/hr
your speed = 5 - 1.5 (or 2 + 1.5) = 3.5 m/hr
