1) x=y
2) 4x= 3y - 3
Answers

Answer:
see attached
use the point-slope form
Step-by-step explanation:
Substitution works to find the solution.
4x = 3x -3
x = -3 = y
The solution is (x, y) = (-3, -3).
__
The first equation graphs as a line through the origin with a slope of 1.
The second equation graphs as a line through (0, 1) with a slope of 4/3, that is, a rise of 4 for each run of 3.
The two lines intersect at (x, y) = (-3, -3), so that point, together with the y-intercepts, can be used to draw the lines.
_____
A line that intersects point (-3, -3) can be written in point-slope form as ...
y +3 = m(x +3) . . . . . for some slope m.
If you were to choose m = -1, this becomes ...
y +3 = -(x +3)
y = -x -6 . . . . . . rearranged to slope-intercept form

While walking to the gym, Marie decides to play a game using a her lucky fair
six-sided die (which she carries with her all the time). Tossing an even number would
indicate walking forward that many steps and, likewise, tossing an odd number would
mean walking backwards that many steps (i.e. if she tosses a 3, she walks backward 3
steps). If the probability that after 2 rolls of the die, she is further away from the gym
that she was at the beginning of the game, can be represented as m/n
for m and n being relatively prime positive integers, find m^2 + n^2 ?

Answer:
1.) 88cm²
2.) 44.5cm²
3.) 141.37cm²
4.) 44cm²
Step-by-step explanation:
Alrighty, we're just going to do an abridged version, but if you need me to explain it more, I can:
1.) 6 x 8 ÷ 2 = 24
8 x 8 = 64
64 + 24 = 88
1.) 88cm²
2.) 2 + 2 + 3 = 7
7 x 5 ÷ 2 = 17.5
9 x 3 = 27
27 + 17.5 = 44.5
2.) 44.5cm²
3.) 3.14 x 3² = 28.27
3.14 x 6² = 113.1
28.27 + 113.1 = 141.37
3.) 141.37cm²
4.) 3.14 x 4² ÷ 2 = 25.135
4 x 2 = 8
8 x 9 ÷ 2 = 36
8 + 36 = 44
4.) 44cm²

Find the value of x - this is circle segments.
Answers
Given:
Diagram of a circle and its two secant from an exterior point.
To find:
The value of x.
Solution:
We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.
Using the above property, we get
[tex](x+7)x=(2+2)2[/tex]
[tex]x^2+7x=(4)2[/tex]
[tex]x^2+7x=8[/tex]
[tex]x^2+7x-8=0[/tex]
Splitting the middle term, we get
[tex]x^2+8x-x-8=0[/tex]
[tex]x(x+8)-1(x+8)=0[/tex]
[tex](x+8)(x-1)=0[/tex]
Using zero product property, we get
[tex](x+8)=0[/tex] and [tex](x-1)=0[/tex]
[tex]x=-8[/tex] and [tex]x=1[/tex]
Side cannot be negative.
Therefore, the only possible value of x is 1.

a skydiver jumps out from the plane at 10,000 feet above the ground. the skydiver decends at a rate of 175 feet per seconds. how high in the air is the skydiver when he opens his parachute after 25 seconds?
Answers
Answer:
5625 feet
I hope it's helps you
Answer:
5625 feets
Step-by-step explanation:
Rate(feet/seconds) = height(feets)/time(seconds)
175 = x/25
x = 4375
After the skydiver opens his parachute the height reduces
Initial height – reduced height
10000 – 4375
= 5625 feets

Step-by-step explanation:
The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the third mark, 1 dot above the fourth mark, 3 dots above the fifth mark and 1 dot above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.8. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)
1.5
2.2
3.0
4.6
Answers
Answer:
The number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders is:
3.0
In order to find the variability between the two sets we divide the mean absolute deviation of the first set of data by the mean absolute deviation of the second set of the data.
The MAD of first set of data is: 1.2
and MAD of second set of data is: 0.4
Hence, let n be the number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders.

find the experimental probability and the theoretical probability.
Answers
The experimental probabilities of each outcome are given as follows:
Outcome of 1: 9/30 = 3/10.Outcome of 2: 5/30 = 1/6.Outcome of 3: 5/30 = 1/6.Outcome of 4: 7/30.Outcome of 5: 4/30 = 2/15.The theoretical probability of each outcome is given as follows:
1/5.
How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.
For the experimental probability, we consider the 30 trials in the table.
For the theoretical probability, we consider that each of the outcomes is equally as likely, hence the probability is given as follows:
p = 1/5.
