Answer:
Add the two equations together to eliminate x from the system.
(−6x+6y=6)+(6x−3y=12)=(3y=18)
Divide each term by 3 and simplify.
y=6
Substitute the value found for y into one of the original equations, then solve for x.
x=5
The solution to the independent system of equations can be represented as a point.
(5,6)
The result can be shown in multiple forms. Point Form: (5,6)
Equation Form: x=5,y=6

Answer:
y = 2x + 1
Step-by-step explanation:
Use slope-intercept form ( y = mx + b ) where m is the slope ( rise over run ) and the y-intercept is 1 because where x = 0, y =1. You can either use rise over run to solve the slope or plug in an x and y value on the line and solve algebriacally.
Rise Over Run:
Take two values on the line, for example, (0,1) and (1,3) y is the rise and x is the run, so write each one with y over x in fraction form.
(0,1) = [tex]\frac{1}{0}[/tex] (1,3) = [tex]\frac{3}{1}[/tex] then subtract the second value from the first
[tex]\frac{3}{1}[/tex] - [tex]\frac{1}{0}[/tex] = [tex]\frac{2}{1}[/tex] which simplifies to 2. So the slope is 2.
Algebra:
plug a coordinate on the line into the equation y =mx + 1. For example (1,3)
3 = m(1) + 1 anything multiplied by 1 is itself so we can cancel out the 1 in the equation
3 = m + 1 subtract 1 from both sides
-1 -1
2 = m each method shows the slope is 2 so now we can put it together into the answer, y = 2x + 1
The equation of the line shown in table is y=2x+1.
What is equation?Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.
How to form equation?We have been given a line and we have to form equation of that line. First of all we have to take two points and then we will be able to form that equation.
We have taken (0,1),(1,3). The equation is formed under:
y-1=(3-1)/(1-0)*(x-0)
y-1=2x
y=2x+1
Hence the equation of the line is y=2x+1.

A piece on a game board moves forward 8 spaces on its first turn and moves backward 3 spaces on its second turn. If the pattern continues, how many turns will it take for the piece to move at least 30 spaces? Please help me!!!
Answer:
It will take 8 turns
Step-by-step explanation:
Answer:
11 turns
Step-by-step explanation:
A piece on a game board moves forward 8 spaces on its first turn and moves backward 3 spaces on its second turn. How many space it moves for each 2 turns?
Space it moves for each 2 turns = 8-3 = 5
The question is asking for how many turns will it take to move 30 spaces, since we know that the piece will move for 5 space each 2 turns(let's call this a cycle).
Cycle required for 30 spaces = 30/5 = 6
At this point, many will think that the no. of turns required is 6x2 = 12, but that's not the answer! Do you still remember how the cycle works? 1st up 5, 2nd down 3! On the 11th turn, the piece actually moved for 5x5 + 8 space = 33 spaces, which is greater than 30!
∴The answer is 11 turns

What is the center & Radius of X²+Y²+2x-24=0
Answer:
the center is at (1, 0) with a radius of 5.
Step-by-step explanation:
(x - h)2 + (y - k)2 = r2
Remember, the center is a (h, k) and the radius is r.
So we start with,
(x2 -2x + 1) + y2 =25
(x - 1)2 + (y - 0)2 = 25

A ball is dropped from a height of 192 inches onto a level floor. After the third bounce it is still 3 inches off the ground. Presuming that the height the ball bounces is always the same fraction of the height reached on the previous bounce, what is that fraction?
Answer: The required fraction = [tex]\dfrac18[/tex]
Step-by-step explanation:
Let the required fraction = [tex]\dfrac{p}{q}[/tex]
Given: Initial height = 192 inches
Height of ball after second bounce = [tex]\dfrac{p}{q}\times192[/tex]
Height of ball after third bounce = [tex]\dfrac{p}{q}\times\dfrac{p}{q}\times192=192\dfrac{p^2}{q^2}[/tex]
After the third bounce it is 3 inches off the ground.
So,
[tex](\dfrac{p}{q})^2192=3\\\\\\(\dfrac{p}{q})^2=\dfrac{3}{192}\\\\(\dfrac{p}{q})^2=\dfrac{1}{64}\\\\(\dfrac{p}{q})^2=(\dfrac{1}{8})^2\\\\ \dfrac{p}{q}=\dfrac{1}{8}[/tex]
Hence, The required fraction = [tex]\dfrac18[/tex]

A dilation with a scale factor of 2 is applied to the three line segments shown. The resulting images are P′Q′¯¯¯¯¯¯¯, A′B′¯¯¯¯¯¯¯, and M′N′¯¯¯¯¯¯¯¯¯.
What are the lengths of the images?
Drag the answer into the box to match each segment.
Answer:
Step-by-step explanation:
Formula to determine the scale factor,
Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]
2 = [tex]\frac{P'Q'}{PQ}[/tex]
2 = [tex]\frac{P'Q'}{2}[/tex]
P'Q' = 4 cm
Similarly, for the length of A'B',
2 = [tex]\frac{A'B'}{AB}[/tex]
2 = [tex]\frac{A'B'}{1.5}[/tex]
A'B' = 3 cm
For the length of M'N',
2 = [tex]\frac{M'N'}{MN}[/tex]
2 = [tex]\frac{M'N'}{3}[/tex]
M'N' = 6 cm
Answer:
P'Q' = 4 cm A'B' = 3 cm M'N' = 6 cm

Which area model represents 0.4 x 0.7 = 0.28?
Answer:
the one with pink and white at the top, and the same one with purple and blue on the bottom
Step-by-step explanation:
The area model that represents 0.4 x 0.7 = 0.28 is the first graph, with pink color, purple colour, white colour and blue color.
Which area model represents 0.4 x 0.7 = 0.28?The area model that represents 0.4 x 0.7 = 0.28 is determined by observing the graph with 0.4 row or column times row or column with 0.7.
The solution of the expression is calculated as follows;
0.4 x 0.7 = 0.28
So we can see that the first graph has 0.4 column and 0.7 row, creating the desired result need for the product of 0.4 and 0.7.
Thus, the area model that represents 0.4 x 0.7 = 0.28 is determined as the first graph with pink color, purple colour, white colour and blue color.

The quality-control department of Starr Communications, the manufacturer of video-game cartridges, has determined from records that 1.6% of the cartridges sold have video defects, 0.7% have audio defects, and 0.4% have both audio and video defects. (a) What is the probability that a cartridge purchased by a customer will have a video or audio defect?
Answer:
The probability that a cartridge purchased by a customer will have a video or audio defect is 1.9%
Step-by-step explanation:
The given parameters in the question are;
The percentage of cartridges that have video defects, P(X) = 1.6%
The percentage of cartridges that have audio defects, P(Y) = 0.7%
The percentage of cartridges that have both audio and video defects, P(X and Y) = 0.4%
The probability is with regards to inclusive evets
The probability of inclusive events 'X' and 'Y' which are events that can happen at the same time are given as follows;
P(X or Y) = P(X) + P(Y) - P(X and Y)
Therefore, we have;
P(X or Y) = P(Video or Audio) = 0.016 + 0.007 - 0.004 = 0.019
∴ P(Video or Audio) = 1.9%
The probability that a cartridge purchased by a customer will have a video or audio defect = 1.9%
