Answer:

(-4,-2)

x=-4

y=-2

Step-by-step explanation:

-3x-4y=20

3(x-10y=16)=3x-30y=48

The reason I multiplied 3 to the second equation is for when we add the equations together the x will cancel out.

  -3x-4y=20

+  <u>3x-30y=48</u>

  -34y=68

Divide -34 from both sides.

y=-2

To find x you need to plug in -2 for y into one of the equations.

x-10y=16

x-10(-2)=16

Remember a negative times a negative equals a positive.

x+20=16

Subtract 20 from both sides.

x=-4

Hope this helps!

If not, I am sorry.

Idk what to do here could someone help me ??

For 1 kilometer, the customary measure is 62/100 miles. The easiest way to think about this is to forget that the units are miles. Instead think of it as money. If I have $1 that means I have 100 out of 100 cents. So if I have 50 cents my fraction is 50/100; and the way we write this is 0.50... if I have 32 cents then my fraction is 32/100 and we write this as 0.32. So if you have 62 cents out of a 100, how would you write that in decimal form?

Which of these is a complex number? <br><br> A. <br><br> B. <br><br> C. <br><br> D.
Step2247 [10]

Answer:

option D

\frac{8}{3} + \sqrt{\frac{-7}{3} }

Step-by-step explanation:

Given in the question are 4 number

5√1/3 - \frac{9}{\sqrt{7} }

2 - \frac{1}{\sqrt{11} }

9 + 3\sqrt{\frac{5}{2} }

\frac{8}{3} + \sqrt{\frac{-7}{3} }

A Complex Number is a combination of a Real Number and an Imaginary Number

<h3>Example </h3>

a + ib

where a is real number

            b is imaginary number

            i is 'lota' which is √-1

<h3>So according to the definition above </h3>

\frac{8}{3} + \sqrt{\frac{-7}{3} } is complex number in which

\frac{8}{3} is real part

\sqrt{\frac{7}{3} } \sqrt{-1} = \sqrt{\frac{7}{3} } i is the imaginary part
