Answer:
x-intercept = (-4/35, 0)
y-intercept = (0, 4).
Step-by-step explanation:
x intercept occurs when y = 0 so
35x + 4 = 0
x = -4/35.
Y - intercept ( when x = 0):
y = 35(0) + 4 = 4.
Answer:
If Z is a complex number:
Z = a + b*i
where a and b are real numbers, and i is an imaginary number.
Then "a" is the real part.
"b*i" is the imaginary part.
The conjugate of Z is:
Zc = a - b*i
So the sign of the imaginary part changes.
Then:
Sum:
Z + Zc = (a + bi) + (a - bi) = 2*a + 0 = 2*a
and remember that a is a real number, then 2*a is also a real numer.
The correct answer is "A real number".
Difference:
Z - Zc = (a + bi) - (a - bi) = 2b*i
and this is a pure imaginary number, so here the correct answer is: "a pure imaginary number"
Answer:
(2,3)
Step-by-step explanation:
The solution to a linear system is always where both of the lines intersect.
Y= 3/5x-2 if you are solving for y. You first subtract the 10 so it would be 3x-10=5y then divide everything by 5. Giving you a slope of 3/5. And 10/5=2 . So Y=3/5x-2
