Answer:
(x, y, z) = (1, 2, 3)
Step-by-step explanation:
The equations that result from reduction to row-echelon form are ...
x = 0.4 +0.2t
y = 5.6 -1.2t
z = t
Then t must have a value 5n+3 for 0 ≤ n < 1. That is, t=3.
x = 0.4 +0.2(3) = 1
y = 5.6 -1.2(3) = 2
z = 3
The integers that satisfy are (x, y, z) = (1, 2, 3).
Answer:
$200
Step-by-step explanation:
4 different streets with 5 customers on each means 4*5 customers or 20 customers. If he has 20 customers and he gets $10 from each one, thats 20*10. he collected $200
The diameter would be 400 because one of the two formulas to find a circumference is C= pi (D) so according to ur information, the diameter would be 400
Answer:
17
Step-by-step explanation:
According to the graph below there are just 3 real zeros. If you count everything, there would be 17. I have chosen the real ones. But there are 14 others that all involve complex numbers. I don't know how you would find them.
Summary
There are 17 roots in total. 3 are real.
Hey there
2/5 + 1/10 is a fraction
You multiply 2/5 by 2
2/5 = 4/10
<span>4/10 + 1/10 = 5/10
</span>
Now you reduce 5/10
<span>5/10 = 1/2 </span>
<span>1/2</span>
