Answer:
1. (2,5),(1,3.5),(4,8),(6,11)
2. This is not a proportional relationship (explanation below)
Step-by-step explanation:
For the plotting, if you take some random x values and multiply by 1.5 and add 2 to them.
This can't be a proportional relationship. A proportional relationship means the x and y values' ratios have to stay the same. However, because 2 is added to 1.5x, the equation is not proportional.
The four x and y values that make the equation true are (0,2), (-1.333,0), (1,3.5), and (1,3.5).
What in mathematics is a proportionate relationship?When the ratios of two variables are equal, they form proportional relationships. Another way to think about them is that in a proportionate relationship, one variable is always equal to the constant value of the other.This constant is known as the "constant of proportionality." To find: The four sets of x and y values required to solve the equation. Put the (x, y) coordinates on a coordinate plane.Therefore,
We select several x and y values,
1) Take x=0,
y = 1.5(0) + 2 =2.
The point is (0,2).
2) Take y=0,
0 = 1.5x + 2
x = -2/1.5 = -1.333
The point is (-1.333,0).
3) Take x=1,
y = 1.5(1) + 2 = 3.5
The point is (1,3.5).
4) Take y=1,
1 = 1.5x +2
1.5x = -1
x = -1/1.5 = -0.666.
The point is (-0.666,1).
The four sets of x and y numbers that make the equation true are (0,2), (-1.333,0), (1,3.5), and (0,2).

A bag contains 120 marbles. Some are red the rest are black. There are 19 red marbles for every black marble. How many red marbles are in the bag?
Answer:
114
Step-by-step explanation:
Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)
19+1= 20
20 units= 120 (Data from 1st sentence)
1 unit= 120/20= 6
19 units= 120-6= 114 (Values solved in working above)
Ans: There are 114 red marbles.

Regent Stadium charges $20 for a seat in the bleachers, $30 for an end zone seat, and $40 for the excellent seats near the 50-yard line. When the stadium is full, 500 tickets were sold for a total of $14,000. The number of bleacher seats is the same as the number of end zone and 50-yard line seats combined.
Answer:
The number of bleachers seat sold = 200
The number of end zone seats sold =200
The number of excellent seats sold =100
Step-by-step explanation:
Let there are bleachers seats =x
The number of zone seats =y
The number of excellent seats =z
So, we can set up equations for given sentences as
x+y+z= 500
20 x+30 y+40 z=14000
x=y
Substitute x as y into first two equations
y+y+z=500
20 y+30 y+40 z=14000
Simplify each
2 y+z=500
50 y+40 z= 14000
Multiply 2 y +z=500 by -40 to eliminate z terms when we add them.
-80 y-40 z=-20000
Add this with 50 y +40 z=14000, which gives
-30 y=-6000
Divide both sides by -30
y=200
Now, plug in y as 200 into any of the equations to find z.
2(200)+z=500
400+z =500
Subtract both sides 400.
z=100
Now, we know x=y
So, x=200

Answer:
y = - [tex]\frac{1}{3}[/tex] x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 7) and (x₂, y₂ ) = (- 3, 6)
m = [tex]\frac{6-7}{-3+6}[/tex] = [tex]\frac{-1}{3}[/tex] = - [tex]\frac{1}{3}[/tex] , thus
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 6 ), then
6 = 1 + c ⇒ c = 6 - 1 = 5
y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line

m<4=
m<5=
m<6=
m<7=
m<8=
m<10=
m<11=
m<12=
m<13=
m<14 =
Answer:
a. m<1 = 105° - 63° m<1 = 42°
b. m<3 + m<2 + m<1 = 180° m<3 = 75°
c. m<4 = m<1 m<4 = 42°
d. m<5 = m<2 m<5 = 63°
e. m<6 = m<3 m<6 = 75°
f. m<7 = m<9 m<7 = 105°
g. m<8 = m<6 m<8 = 75°
h. m<10 = m<8 m<8 = 75°
i. m<11 = m<4 m<11 = 42°
j. m<12 = 180° - m<11 m<12 = 138°
k. m<13 = m<11 m<13 = 42°
l. m<14 = m<12 m<14 = 138°
Step-by-step explanation: Sorry if not all are correct
Applying the relationship existing between angle pairs, the measure of each angle in the image are:
m<1 = 42°
m<3 = 75°
m<4 = 42°
m<5 = 63°
m<6 = 75°
m<7 = 105°
m<8 = 75°
m<10 = 75°
m<11 = 42°
m<12 = 138°
m<13 = 42°
m<14 = 138°
Given that a || b, where:
m<2 = 63°m<9 = 105°, the missing angle measures will be determined as follows:Find m<1:
m<1 + m<2 = m<9 (exterior interior angle theorem)
Substitutem<1 + 63° = 105°
m<1 = 105° - 63°
m<1 = 42°
Find m<3:
m<1 + m<2 + m<3 = 180° (angles on a straight line)
Substitute42° + 63°+ m<3 = 180°
105° + m<3 = 180°
m<3 = 180° - 105°
m<3 = 75°
Find m<4:
m<4 = m<1 (vertical angles theorem)
Substitutem<4 = 42°
Find m<5:
m<5 = m<2 (vertical angles theorem)
Substitutem<5 = 63°
Find m<6:
m<6 = m<3 (vertical angles theorem)
Substitutem<6 = 75°
Find m<7:
m<7 + m<6 = 180° (corresponding angles theorem)
Substitutem<7 + 75° = 180°
m<7 = 180° - 75°
m<7 = 105°
Find m<8:
m<8 = m<6 (alternate interior angles theorem)
Substitutem<8 = 75°
Find m<10:
m<10 = m<6 (corresponding angles theorem)
Substitutem<10 = 75°
Find m<11:
m<11 = m<4 (alternate interior angles theorem)
Substitutem<11 = 42°
Find m<12:
m<12 = m<6 + m<5 (alternate interior angles theorem)
Substitutem<12 = 75° + 63°
m<12 = 138°
Find m<13:
m<13 = m<11 (vertical angles theorem)
Substitutem<13 = 42°
Find m<13:
m<14 = m<12 (vertical angles theorem)
Substitutem<14 = 138°
