Answer:

The constant is actually 40 because every minute, 40 more copies are made. The equation would be c = 40t.

Step-by-step explanation:

right 2 and down 1 so its (2,-1)

Answer:

$3

Step-by-step explanation:

The equation we can create for this respective problem is "10x = 30" where the 10 represents the dollars and the 30 represents the tickets. We can start off by dividing each side by 10 since the coefficient is accompanied by a variable, therefore, the inverse would be division. 30/10 equals 3, thus making the answer $3 per ticket.

Hope this helps!  :D

Answer:

One ticket costs 0.333...

Hope this helps

Step-by-step explanation:

10 / 30 = 0.33333...

For example,

If it was 10 tickets for 30$, one ticket would cost 3$. But it is the opposite, it's 30 tickets for 10$.

30 / 10 = 3

Answer:

y = -1.50x + -3

---------------------------------------------

Step 1: Calculating Slope (m).

m = y2-y1/x2-x1

m = 3-0/-4--2

m = 3/-2

m = -1.50

Now putting value of m in equation (i)

y = -1.50x + b

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (-2,0) for calculating y-intercept:

y = mx + b

0 = -1.50(-2) + b

0 = 3 + b

-3 = b

b = -3

Now putting value of b in equation

y = -1.50x + -3

Answer:

lower right

Step-by-step explanation:

The lower quartile is located at the left side of the box

The upper quartile is located at the right side of the box

The lower quartile 24 and upper quartile 42

are positioned correctly on the lower right box plot

to get the slope of any straight line, we simply need two points off of it, let's use the ones in the picture below

[tex](\stackrel{x_1}{-2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{2}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{(-2)}}} \implies \cfrac{2 }{2 +2}\implies {\LARGE \begin{array}{llll} \cfrac{1}{2} \end{array}}[/tex]

The total amount of corn starch left is 320 grams.

He gives each student 80 grams of corn starch from a 2-kilogram bucket.

Each students collected 80 grams of corn starch.

Therefore,

1 student = 80 grams of corn starch

His class has a total of 21 students.

Therefore,

total mass of corn starch distributed = 21 × 80

total mass of corn starch distributed = 1680 grams

The corn starch from the bucket = 2 kg

1kg = 1000 g

2kg = 2000g

Hence,

The corn starch from the bucket = 2000 grams

Finally,

amount in grams of corn starch left  = 2000 - 1680

amount in grams of corn starch left  = 320 grams.

Answer:

Step-by-step explanation:

i think as it follows the rule y=Mx+C where C is the intercept and that is -2

The value of angles x,  ∠DEA, and ∠AEB are 14.5, 39.5, and 140.5 degrees respectively.

An angle in Euclidean geometry is composed of two rays that share a common terminal and are known as the angle's sides and vertices, respectively. In the plane where they are positioned, two rays can create angles. When two planes overlap, angles are also created. These are the so-called dihedral angles. The angle formed by the rays that are perpendicular to the two intersecting curves at the point of junction is another property of intersecting curves. The length of an angle or rotation can also be described using the word angle.

Calculations:

Supplementary angles are angles that sum up to 180degrees.

We can see that:

m<DEA + m<AEB = 180

x+25+9x+10 = 180

10x + 35 = 180

10x = 180 - 35

10x = 145

x = 145/10

x = 14.5

Get  ∠DEA

∠DEA = x + 25

∠DEA = 14.5 +25

∠DEA = 39.5 degrees

Get ∠AEB:

∠AEB = 9x+10

∠AEB = 9(14.5) + 10

∠AEB = 130.5 + 10

∠AEB = 140.5 degrees

Answer:

im pretty sure its option number 2

Answer:

x = 35

Step-by-step explanation:

we know that all triangles add up to 180

you first need to make an expression in which the angles equal 180

105 + 140 + x = 180

         145 + x = 180

subtract 145 from both sides

                  x = 35
