Add the numbers they gave you and subtract it from the total to get the unknown so 100-(24+42)=34 as a decimal it will be .34 and as a percent it is 34%.

Find the x-intercept and y-intercept of the line. -3x+6y=11
ryzh [129]

Answer:

x- intercept is at ( - 3 \frac{2}{3} ,0).

y- intercept is at (0,1 \frac{5}{6} ).

Step-by-step explanation:

The x-intercept occurs when y=0.

Thus, substitute y= 0 into the equation to find the x- intercept.

-3x +6y= 11

When y= 0,

-3x +6(0)= 11

-3x= 11

x= 11 ÷ (-3)

x =  -  \frac{11}{3}  \\ x =  - 3 \frac{2}{3}

The y-intercept occurs at x= 0.

When x= 0,

-3(0) +6y= 11

6y= 11

y= 11÷ 6

y = 1\frac{5}{6}

What can you say about the nature of any other zeros of the quadratic equation , which has one complex zero? Explain your answer
siniylev [52]
Answer:
There is another complex zero which is a conjugate of the known complex zero.

Explanation:
A quadratic equation s a 2nd order polynomial.

Therefore it can have 2 real zeros or 2 complex zeros.
Because complex zeros always occur as conjugate pairs, there will be another complex zero which is a conjugate of the known complex zero.

For example, if the known complex zero is of the form (a + ib), then the other complex zero is (a - ib), or vice versa.
