When interpreting graphs from real-world situations, what can the slope tell you about the situation?

Answers

When interpreting graphs of real world situations, the slope of each part tell you the average rate of change (increase or decrease) of the dependent variable with respect to the independent variable. This is, how much the dependent variable increased (or decrease) per each unit the independent varaible increased, in average.

slope = change in independent variable / change in dependent variable

slope = Δy / Δx

Increase or decrease of the dependent variable

the number of red and blue marbles in the bag?
O 4 red marbles and 6 blue marbles
O 4 red marbles and 5 blue marbles
O 6 red marbles and 8 blue marbles

Answers

Answer:

4 red marbles and 6 blue marbles is the correct answwer

Step-by-step explanation:

Answer:

A.) 4 red marbles and 6 blue marbles

Step-by-step explanation:

If you times 2 x 2 then you will get 4

If you times 3 x 2 then you will get 6

And since the ratio is red : blue

2 : 3 is equivalent to 4 : 6

Just like  [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.

if you were to do a fraction graph, 2 of the 3 [tex]\frac{1}{3}[/tex] bars would be the same length of 4 [tex]\frac{1}{6}[/tex] bars:

What is the y intercept of y=6x+3

Answers

Answer:

y = 6 x − 3

Step-by-step explanation:

The slope-intercept form is  y = m x + b , where  m  is the slope and  b  is the y-intercept.

y = m x + b

Using the slope-intercept form, the y-intercept is  − 3 .

b = − 3

Answer:  

-3

Explanation:

I remember the formula to be y=mx+b, and mx representing the slope times x.  Therefore, b would equal the y-intercept, or in this case 3.  Using slope intercept form, you get -3.    

y = 3(x+ 4)^2+ 4 plz find the vertex and whether the graph has a minimum or maximum point

3(2c + 5) = 39
What is the answer ?

Answers

Answer:

c=1

Step-by-step explanation:

Simplifying

3 + 2c = 5

Solving

3 + 2c = 5

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2c = 5 + -3

Combine like terms: 3 + -3 = 0

0 + 2c = 5 + -3

2c = 5 + -3

Combine like terms: 5 + -3 = 2

2c = 2

Divide each side by '2'.

c = 1

Simplifying

c = 1

Answer:

 =  4

Step-by-step explanation:

Subtract  15 from both sides of the equation

6+15=39

6+15−15=39 − 5

Simplify

6=24

Divide both sides of the equation by the same term

(6=24)/6

Simplify

=4

Answers

Sum of the interior angles of a pentagon is 720 degrees. Sum of two angles that form a bisected line is 180 degrees. So interior angles going clockwise are 138 degrees. 128 degrees. 119 degrees. 180- 2*t degrees. And 180 - 3*t degrees. So sum of angles is:
138+128+119+(180 - 2*t) + (180 - 3*t) = 720

25 = 5*t

t = 5 degrees.

Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount.
Together the coaches spend $40. How much does each cone cost?
( write an equation to model the situation. Then solve for x)

Answers

Answer:

x=16

Step-by-step explanation:

1 soccer ball =$12

2 makes $24.

24+16=40

so both coaches spend 8 bucks for 4 cones

Each cone costs $2, and the cost is calculated as follows: 8x = 40 - 2 *p, where p is equal to the cost of a football.

What is a Linear equation?

A linear equation is an algebraic equation of the form ax + by +c, is and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given that, Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount. Together the coaches spend $40.

Let x be the number price of the cone.

Thus each coach spends  = 4x  +12

Thus, in total, they spend = 40

4x  +12 +  4x  +12 = 40

8x = 40 -24

8x = 16

x = 2

Therefore, Each cone costs $2 and the equation for calculating the price of the cone is: 8x = 40 - 2 * the price of a football.
