Answer:

=3-4i

Step-by-step explanation:

So we have:

(2-i)-(-1+3i)

First, distribute:

=(2-i)+1-3i

Combine like terms:

=-i-3i+2+1

Add:

=-4i+3

So, in the a+bi format, we will have:

=3-4i

Checking the graph:-  when x = 1 y = 0  so it cant be y = x^4

y = log4 x
is the same as

x = 4^y 

Checking the graph,  when x = 4, y = 1
Plugging these into the above 4 = 4^1 = 4

So the correct choice is first one

Q26. Meena bought a cake and left it on the table in the morning. When she came home in the evening, she saw that of the cake ha
Gwar [14]

The answer is; 24/75 of the entire cake remained

If 2/5 of the initial cake was eaten, the 3/5 is what remained

MInu ate 1/3 of the 3/5 = 3/15

3/5 – 3/15 = 6/15 remained

Her brother ate; 1/5 of 6/15 = 6/75

6/15 – 6/75 = 24/75 remained

I don't know how to do this​
Gre4nikov [31]

Answer:

x = -11/5 and y = 24/5

Step-by-step explanation:

Use elimination.

First, we need to multiply so that at least one variable can cancel out.

We can multiply the top equation by 2.

So we get

4x + 6y = 20

Then, we can use elimination.

The x's cancel out.

So we get 5y = 24

Or y = 24/5

Then, we can plug in this y value back into the first equation to find x.

2x + 3(24/5) = 10

2x + 72/5 = 50/5

2x = -22/5

x = -11/5

So x = -11/5 and y = 24/5
