You are told x = 8y -4
Replace x in the second equation with 8y-4:
8y-4 + 8y = 6
Combine like terms:
16y-4 = 6
Add 4 to both sides:
16y = 10
Divide both sides by 16:
Y = 10/16
Simplify:
Y = 5/8
Now replace y with 5/8 do find x:
X = 8(5/8) -4 = 5-4 = 1
X = 1, y = 5/8
(1,5/8)

The winning time for a race are shown in the table.
Which answer describes the average rate of change from year 2 to year 4?
A) the winning time increased by an average of 0.4 second per year from year 2 to year 4.
B) the winning increased by an average of 0.8 second per year from year 2 to year 4.
C) the winning time increased by an average of 0.475 second per year from year 2 to year 4.
D) the winning time increased by an average of 0.267 second per year from year 2 to year 4.
Answer:
The winning time increased by an average of 0.4 second per year from year 2 to year 4.
Step-by-step explanation:
I just took the quiz
The winning time for a race displayed in the table would be:
A). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.
Find the increase in winning time:Given that,
Year Winning Time(seconds)
1 27.5
2 28.4
3 28.7
4 29.2
5 29.44
The total change in the time = (0. + 0.3 + 0.5 + 0.24)/4
= 0.485 seconds
If we round off, it becomes 0.5 seconds.
Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.
Thus, option A is the correct answer.

What is the output of the function when the input is 10? On the graph plot this point and label its coordinates
Answer:
Output value = 20
Step-by-step explanation:
Graph of any function is made up of two values → Values on x axis and Values along y axis.
x values represent the input values and y values represents the output values.
For every x value there is a y value because of which the data set is called to a function.
In other words, a function can't have two output values for a single input value.
If the input value of function is = 10
Then for x = 10, out value (along y axis) will be = 20
Therefore, Output value of the given function is 20.
Determine whether the graph shows a positive correlation, a negative correlation, or no correlation. If there is a positive or negative correlation, describe its meaning in the situation.

The solution is, Option B Negative ,as time passes, speed decreases.
What is Correlation?Positive Correlation= With Increase in x value, y value also increases or vice versa, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases or vice versa, we call it negative correlation.
here, we have,
Description of the Graph
1. The Relation between , Speed and time is depicted on the graph.
2. Minute = x coordinate
Miles per hour= y coordinate
The points shown on the graph , describing the relationship are, (5,15),(10,13.8),(15,11),(20,10),(25,9.8).
There are two types of Correlation
Positive Correlation= With Increase in x value, y value also increases or vice versa, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases or vice versa, we call it negative correlation.
As you can see from the points plotted on the graph ,with increase in x value , y value decreases.
So it is negative correlation.
As, time passes, Speed Decreases, So it is a Negative Correlation.
Option B Negative ,as time passes, speed decreases.

Solve w^2+13w+42=0 by factoring.
Answer: {-7, -6}
Explanation: When an equation has a squared term in it,
it's called a polynomial equation.
The rule for solving a polynomial equation
is to first set it equal to 0, then factor.
Since this equation is already set equal to 0, we can factor the left side.
The left side is a trinomial that can be
factored as the product of two binomials.
The first term in each binomial will be a factor of the w².
Since w² factors a w · w, we use a w as our first term.
For the last terms, we use factors of 42 that add
to 13 and these factors are +7 and +6.
So we have (w + 7)(w + 6) = 0.
So either w + 7 = 0 or w + 6 = 0.
Solving for w in each equation, we find that our solution set is {-7, -6}.

Answer:
the origin is point (0,0) where the two lines meet
It's not in a quadrant
The horizontal line (----) is the x-axis and the vertical line ( | ) is the y- axis
these split the graph into 4 parts, called quadrants.
They're usually labelled in roman numerals (I, II, III, IV)
Quadrant I is the top right
they're labelled counter-clockwise from there so
Quadrant II is the top left
Quadrant III is the bottom left and
Quadrant IV is the bottom right

Step-by-step explanation:
As the figure can be split in to 3 geometric figure,
Rectangle , Triangle and Semi circle ,
So first find the area of these figures then add up them ,
Area of rectangle = Length * width
Length = 20m m and width = 14 mm
hence
Area of rectangle = 20*14 = 280 mm^2
Now ,
Are of Circle = [tex]\\ \pi *d^{2} /4[/tex]
Then Area of semi circle = [tex]\\ \pi *d^{2} /8[/tex]
Hence we have d= 20mm
Putt in semi circle formula we get,
Area of Semi Circle= (3.14)*400/8 = 157 mm^2
Now area of triangle = 1/2 * length*width
length =32-20 = 12 mm
width = 14 mm
putt in the formula we get ,
Area of triangle = 1/2*12*14 = 84 mm^2
Now add these 3 Areas to get total Area,
Total Area = 84+157+280 = 521 mm^2
