What is proportional relationship?
When the value of independent variable changes the value of dependent variable changes. that means if the value independent variables is increase the value of dependent variable will also be increased.

find M angle one and M angle to justify your answers
Answers
Answer:
Step-by-step explanation:
13.
m1 is 120 because angle 120 and angle 1 are tranversal angle
So now we know that angles m1 and m2 are vertically opposite angle
Then m2 = 120
m1 = 120
m2 = 120
14.
angle 1 and 105 have the sum of 180 because they are Interior angles on the same side of the transversal
So angle 1 equals 180-105=75
angle 2 and angle 1 are on a line so the sum of the 2 angles are 180
So: 180 - 75 = 105
m1 = 105
m2 = 75
3x+7y=63 solve for x
Answers
Answer:
[tex]x = 21 - 2\frac{1}{3}y[/tex]
Step-by-step explanation:
3x + 7y = 63
Minus 7y from both sides, then you get...
3x = 63 - 7y
Now we divide both sides by three to find the value of x:
[tex]x = 21 - 2\frac{1}{3}y[/tex]
2. Kieran, Jermaine and Chris play football. Kieran scored 8 more goals than Chris Jermaine scored 5 more goals than Kieran. Altogether they have scored 72 goals. How many goals did they each score?
Answers
Answer:
Step-by-step explanation:
k = x+8
c= x+5
j= x+5
3x+18=72
x = 18
Chris = 23
Kieran = 26
Jermaine = 23
Answer:
Chris = 17 goals
Kieran = 25 goals, and
Jermaine = 30 goals
Step-by-step explanation:
Let K, J, and C stand for the goals scored by Kieran, Jermaine, and Chris, respectively.
We learn that:
K = C + 8 [Kieran scored 8 more goals than Chris]
J = K + 5 [Jermaine scored 5 more goals than Kieran]
K + J + C = 72 [Altogether they have scored 72 goals]
-----
We have 3 equations and 3 unknowns. Therefore, we should be able to find a solution by rearranging and substituting.
Let's start with K + J + C = 72 and find ways to eliminate two of the three variables.
We can substitute for K since K = C + 8
K + J + C = 72
(C+8) + J + C = 72
Rearrange:
2C+8 + J = 72
We can also substitute for J since J = K + 5
2C+8 + J = 72
2C+8 + (K + 5) = 72
Again, we can substitute for K since (K = C + 8)
2C+8 + (C+8) + 5 = 72
2C+8 + (C+8) + 5 = 72
3C +21 = 72
3C = 51
C = 17
---
Since C = 17, we can find K with K = C + 8
K = C + 8
K = 17 + 8
K = 25
---
Since K = 25, we can find J with J = K + 5
J = K + 5
J = 25 + 5
J = 30
===
We find:
C (Chris) = 17 goals
K (Kieran) = 25 goals, and
J (Jermaine) = 30 goals
17 + 25 + 30 = 62 total goals.

Write the recursive definition for this sequence, and then find how many pushups he should do on the 20th day, if he continues.
Answers
Answer:
Day 20 = 67 pushups (64+3)
Step-by-step explanation:
Day 1 = 10 pushups Day 2 = 13 pushups (10+3) Day 3 = 16 pushups (13+3)
He does three more pushups each day.
So day 4 = 19 pushups (16+3)
Day 5 = 22 pushups (19+3)
Day 6 = 25 pushups (22+3)
Day 7 = 28 pushups (25+3)
Day 8 = 31 pushups (28+3)
Day 9 = 34 pushups (31+3)
Day 10 = 37 pushups (34+3)
Day 11 = 40 pushups (37+3)
Day 12 = 43 pushups (40+3)
Day 13 = 46 pushups (43+3)
Day 14 = 49 pushups (46+3)
Day 15 = 52 pushups (49+3)
Day 16 = 55 pushups (52+3)
Day 17 = 58 pushups (55+3)
Day 18 = 61 pushups (58+3)
Day 19 = 64 pushups (61+3)
Day 20 = 67 pushups (64+3)
dr. guidry has decided to examine one of her relationships with a scatterplot to double-check for a curvilinear relationship. which relationship will be most important for her to examine?
Answers
Linear regressions can help to examine a curvilinear relationship.
It is possible for two variables to have a relationship known as a curvilinear relationship, in which one variable rises along with the other, but only until a certain point, beyond which the other variable falls as the rise of the first continues.
To evaluate the relationship between two numerical variables visually, scatterplots are utilized. Usually, the X axis represents the explanatory variable and the Y axis represents the dependent variable.
By generating a line that best fits your data, regression takes correlation a step further. While a straightforward linear regression analysis still gives us the R2 value, it now gives us a number that indicates the strength (slope) of the association between X and Y. This knowledge improves our comprehension of the underlying relationship and can be applied to forecast Y values given a certain value of X. However, instead of testing the null hypothesis that the slope of the line depicting the relationship between X and Y is zero, T-tests are now employed.
Hence linear regressions can help to examine a curvilinear relationship.

-1 Is greater than -3/2, because -3/2 is -1.5 as a decimal which is less than -1.

The answer is No.Find the missing number so that the equation has no solutions. -4(-X + 8) = -3(2x + 7) + __x + 9
Answers
In order to have an equation with no solution, the variable x should not appear in the equation and the final sentence must be false.
So, using the variable 'y' to represent the missing number and simplifying the equation, we have:
[tex]\begin{gathered} -4(-x+8)=-3(2x+7)+yx+9 \\ 4x-32=-6x-21+9+yx \\ 4x+6x-yx=32-21+9 \\ 10x-yx=20 \\ (10-y)x=20 \end{gathered}[/tex]Since we want the variable x to disappear (this way we will have 0 = 20, which is false), we need the coefficient (10 - y) to be zero:
[tex]\begin{gathered} 10-y=0 \\ y=10 \end{gathered}[/tex]So the missing number is 10.
