Answer 1

Answer:

The equation is y = 12.5x I believe.

Answer 2

Answer;

The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.

The equation is

y = 12.5 × t

Explanation:

To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:

For example

25

miles

÷

2

hours

=

12.5

miles

hour

A direct proportionality will always result in an equation that resembles this:

y = k x where  y and  x are the related quantities and  k is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. And if the values given are real physical quantities, this constant will contain important information about the situation you are studying.

h(t) = t + 2 + 3; Find h(6)

Answers

If you wanted a step by step:

6 = t in this case so simply plug in 6 to the equation and get 6 + 2 + 3, after adding you’ll have 11.

Answer: h(6) = 11
Answer:

h(6) = 11

Step-by-step explanation:

Hi there !

h(t) = t + 2 + 3

= t + 5

replace t = 6

h(6) = 6 + 5

= 11

what is the slope of the line on the graph?​

Answers

Please post a picture than I will be glad to help

Answer:

Step-by-step explanation:

So you need to take two points off the graph. (x,y) and (x,y)

After that use those points to plug it into this equation

your gonna want to take the Y points from both and subtract from each other.

Do the same for the X points.

Y2-Y1

X2-X1

You'll then divide The Y by the X and that the Rise over Run.  When you graph that. That'll be your answer.

Jenifer bought 6 packages of hotdogs and 8 packages of rolls for $41.50. A package of rolls cost $0.85 less than a package of hotdogs. How much did each package of hotdogs cost?

Answers

Answer:

hotdogs 3.45

rolls 2.60

Step-by-step explanation:

6h + 8r = 41.5

r=h-.85

6h + 8(h-.85)=41.5

6h + 8h - 6.8 = 41.5

14h = 41.5 + 6.8

14h = 48.3

h=48.3/14

h=3.45

r=3.45-.85=2.6

Plz help with graph polynomial

Answers

Answer:

(x + 1 ) is a factor

Step-by-step explanation:

Given a polynomial with roots x = a, x = b , then the corresponding factors are

(x - a) and (x - b)

From the graph

The roots are x = - 1 and x = 4 , thus factors are

(x - (- 1)) and (x - 4) , that is

(x + 1) and (x - 4)

(x + 1) is the required factor

Answer:

  x^2 -5x +6 = 0

Step-by-step explanation:

Perhaps the easiest way to do this is to find the roots of the given equation, then write the equation that has reciprocal roots. The given equation can be factored as ...

  (2x -1)(3x -1) = 0   ⇒   roots 1/2, 1/3

Then the factoring of the equation with reciprocal roots is ...

  (x -2)(x -3) = 0

  x^2 -5x +6 = 0

What is the value of x in this equation

Answers

Answer:

2x-8=3x-2

2x-3x=-2+8

-1x=6

X=6/-1

X=-6

So, you want to move any number with a variable to one side and one without a variable to the other
But first, you must distribute the 2(x–4)
2(x–4) –> 2x–8
Next, move the numbers.
2x–8=3x–2
-8=x–2
-6=x
x is 6
