Answer:
i) (x -y) -y = 11
ii) (x+y) + x² = 8
iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation x² + y² = 25
Step-by-step explanation:
Step(i):-
Given that x =3 and y=-4
i) (x -y) -y = (3-(-4))-(-4) = 3+4+4 = 11
ii) (x+y) + x² = ( 3 -4) + (3)² = -1 + 9 = 8
Step(ii):-
Given equation
x² + y² = 25
we can choose (x,y) = ( 3 , -4)
3²+(-4)² = 25
25 = 25
The ordered pair ( 3,-4) satisfies the equation
second ordered pair ( 3 ,4)
x² + y² = 25
9 + 16 = 25
25 = 25
Final answer:-
i) (x -y) -y = 11
ii) (x+y) + x² = 8
iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation x² + y² = 25

Answer:
Volume is 144 m^3.
Step-by-step explanation:
The formula for the volume of a triangular prism is area of one of the triangles times the depth.
So you first would find the area of the triangle. 6*6/2=18
Then you would multiply it by the depth: 18*8=144 m^3.

2.7 as a percentage for this problem
Answer:
270%
Step-by-step explanation:
Hey there!
Step by step explanation:
2.7 is break apart to 200% and 70%. In decimal form, the 7 is 70. 1.0 is also known as 100. This means that 200 would be 200% since 1.00 is equal to 100 and 100 is equal or known as 100%. Now we can add 200% and 70% which would be 270%.
This means that 2.7 in a percent form is 270%.

Computers store information in units called bits and bytes. There are 8 bits in one byte of data. Select the number of bits in one byte as a power with a base of 2.
Answer:
2^3
Step-by-step explanation:
Given that:
8 bits = 1 byte
To express 1 byte in bits in power notation with a base of 2 ;
1 byte = 8 bits
8bits = 2^x
8 bits = 2 * 2 * 2
8bits = 2^3
Hence,
1 byte = 2^3 bits

Solution:
The equation of a straight line is in the form y = mx + b, where m is the slope of the graph and b is the y intercept (value of y when x = 0). To graph the line, online geogebra graphing calculator was used for plotting the two graphs by writing the equation of the graphs.
After plotting the two graphs, the intersection of the two lines should be traced to get the x coordinate and y coordinate of the point. This point is the solution of the two graph equations, hence:

PLS HELP ASAP ILL GIVE BRAINLY
Answer:
Please check the explanation.
Step-by-step explanation:
Given the table
Minutes 6 15 27
Pages 20 50 90
Given two points to find the slope
(6, 20)(15, 50)Finding the slope between (6, 20) and (15, 50)
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [50 - 20] / [15 - 6]
= 30 / 9
= 10/3
Thus, the slope = m = 10/3
Using the point-slope form of the linear line function
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 10/3 and the point (6, 20)
[tex]y-20=\frac{10}{3}\left(x-6\right)[/tex]
Add 20 to both sides
[tex]y-20+20=\frac{10}{3}\left(x-6\right)+20[/tex]
[tex]y=\frac{10}{3}x-20+20[/tex]
[tex]y=\frac{10}{3}x[/tex]
Therefore, the rule relating the minutes, x, to the number of pages, y.
[tex]y=\frac{10}{3}x[/tex]
Determining the number of pages when the minutes equal 72
We already got the equation or rule relating the minutes, x, to the number of pages, y.
[tex]y=\frac{10}{3}x[/tex]
substitute x = 72
[tex]y=\frac{10}{3}\left(72\right)[/tex]
[tex]y=\frac{720}{3}[/tex]
[tex]y=240[/tex]
Therefore, the total pages are 240 when the minutes equal 72
