What are the values of a and b ?

Answer:

colder then warmer

Step-by-step explanation:

The unit rates of   y = –2x is -2, for y = 0.75x the unit rate is 0.75, for 2y = 9x then the unit rate is 4.5 and for  equation –4y = 18x the unit rate is -4.5

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Unit rate is the ratio of two different units, with denominator as 1.

For  y = –2x then the unit rate is -2

For y = 0.75x then the unit rate is 0.75

For 2y = 9x then the unit rate is 9/2 or 4.5

For –4y = 18x then the unit rate is -18/4 or -4.5

Hence, the unit rates of   y = –2x is -2, for y = 0.75x the unit rate is 0.75, for  2y = 9x then the unit rate is 4.5 and for  –4y = 18x the  unit rate is -4.5

Answer:

The constant of proportionality is 3.

Step-by-step explanation:

Constant of proportionality is found by doing k = [tex]\frac{y}{x}[/tex]. Point (2,6) is on the line, so if we plug in point (2, 6) into the equation to solve for the constant of proportionality, we get [tex]k=\frac{6}{2}[/tex] or k = 3. The constant of proportionality is 3.

Answer:

3/-2

Step-by-step explanation:

the way i learned how to find slope from a table was to calaucate 2 points.usually the first 2 pairs. so in your table you would take the points(1,8)&(3,5) then you subtract your x&ys.

1-3&8-5 then your x goes on bottem and y on top.

1-3=-2

8-5=3

slop is 3/-2

see how i wrote it out in the picture.

28j + 21

Answer:

28j + 21

Step-by-step explanation:

The first step is to distribute 7 (2j + 3 +2j). After you distribute you get 14j + 21 + 14j. Next, you need to combine like terms. 14j + 14j is 28j.

Then you have the expression 28j + 21.

Answer:

50 degrees

Step-by-step explanation:

The angles of a triangle add up to 180 degrees. We would set up the equation like this:

2x+18 + 4x+11 + 55 = 180

Combine like terms:

6x + 84 = 180

Solve for x:

6x = 96

x = 16

We substitute 16 back in for x and see the measure of the smallest angle.

2(16)+18 = 50

4(16)+11 = 75

55

The smallest angle here in 50 degrees.

Answer:

2x + 18 = 50

Step-by-step explanation:

2x + 18 + 4x + 11 + 55 = 180

6x + 84 = 180

180 - 84 = 96

6x = 96

96/6 = 16

x = 16

2(16) + 18 = 50

55

4(16) + 11 = 75

Answer:

For this one, we have to break it into two pieces.

(I made them into a small box and and big box)

The measurements of the small box are 7*5*6.

The measurements of the big box are 20*5*9.

Using this information, we can make the following equation and solve it quickly.

(7*5*6) + (20*5*9)

(210) + (900)

1,110

Thus, the volume of this box is 1,110 in. ^2
