You're given the y-intercept, which is (0,5), so to complete the slope intercept form, you now need to find the slope. slope is the change in y over the change in x, so take points (4,-1) and (2,2) for instance and apply the formula; -1-2= -3 and 4-2=2, so the change in y is -3 and the change in x is 2. to find the slope, you divide change in y by change in x, which is -3/2. from here, you can gather that the slope intercept form is y= -3/2x + 5

Have 5 pieces of candy and 29 people. How many pieces are the candy divided into for everyone to get a piece.

Ivanshal [37]

Answer:

everyone gets 5 pieces and the rest gets thrown out

Step-by-step explanation:

29/5=5.8

but obviously ur not gonna break the candy into .8 so everyone just gets 5 so its even

For a certain commodity the supply equation is given by S = 2p + 5 At a price of $1, there is a demand for 19 units of the commo

slava [35]

Answer:

The demand equation is: D=-4p+23

Step-by-step explanation:

To get started, we should keep in mind that the market price (p=3) occurs when supply equals demand ,therefore when p=3

S=2(3)+5=11

Thus, when p=3 D=11 and, according to the problem when p=1 D=19.

We already know two points on the demand curve. Great!

The demand equation is linear, so it has form D=bp+c.

The variable b is the slope of the demand linear equation . It can be computed through the formula

$b=\frac{y2-y1}{x2-x1}$ . equation 1

Substituting the two points (3,11) and (1,19) on equation 1.

$b=\frac{19-11}{1-3} =\frac{8}{-2}$

b=-4

Now we can find the value of intercept of the demand equation c trough point-slope form y-y1=b(x-x1).

We can use any of the points. Let's take (3,11) and write in point-slope :

y-11=-4(x-3)

y=-4x+11+12

y=-4x+23

Rewrite the linear equation according our variables D and p

D=-4P+23

Finally we found the demand equation !

1) Find an equation of the line that passes through thr pair of points (-5,-9) and (2,-7).

Yuki888 [10]

1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is $m=\frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }$ , so in this case, it is $m=\frac{ (-7) - (-9) }{ 2 - (-5) }$ , which comes to $\frac{2}{7}$ . Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y= $\frac{2}{7}$ x- $\frac{53}{7}$ .

2. Use the same process as in question 1 to find:
y=-7x+11

What is 1920000000 Minutes in Hours?

Vlada [557]

Answer:

<h2>1,920,000,000 Minutes = 32,000,000 Hours</h2>

Step-by-step explanation:

$1h=60min\to1min=\dfrac{1}{60}h\\\\\text{therefore}\\\\1,920,000,000min=\dfrac{1,920,000,000}{60}\ h=32,000,000h$
