1) square root of 64

+8/-8

Step-by-step explanation:

I have answered ur question

8×8=64

8

Step-by-step explanation:

is looking for a positive or zero number p such that .

So here you have .

This is basically asking you can you think of a number such that when you multiply it to itself you get 64.

The answer is 8 because 8(8) is 64.

Here are some other perfect squares:

1

4

9

16

25

36

49

....so on.

All of these have nice square roots or principal roots.

The principal roots of those numbers I just mentioned and the reason next is:

1 because 1(1)=1.

2 because 2(2)=4.

3 because 3(3)=9.

4 because 4(4)=16.

5 because 5(5)=25.

6 because 6(6)=36.

7 because 7(7)=49.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
