How to find slope when there is the y intercept and x-intercept?
natta225 [31]
First graph your x and y intercept then pick any two points on the line.
\frac{rise}{run} = \frac{y2 - y1}{x2 - x1}
that's the equation used to find your slope

Example:

(4,2) (8,6) let's say those are the points you pick from the line

so then you subtract 6-2=4 (6 is your y2 and 2 is your y1)

then subtracts 8-4=4 (8is your x2 and 4 is your x1)

then your left with
\frac{2}{4}
if you can reduce the reduce in this case you can which leaves you with
\frac{1}{2}
and that's how you find the slope

Merlin wants to make more money selling fake beards this month than he did last month. All black beards in his shop cost the sam
sukhopar [10]

We know that all black beards cost the same money

And all red beards cost $25

And B represents number of black beards

And R represents number of red beards

We have been given the inequality 20B+25R > 350 to show the target for this month.

The above inequality shows that Merlin needs to make more than 350, hence he made 350 last month

Further, it shows that B has been multiplied by 20, hence the black beard's cost was 20

Convert the following metric units of weight. a. 40 centigrams to grams b. 53 milligrams to grams c. 0.54 grams to decigrams d.
liubo4ka [24]

Answer:

a) 0.4 grams

b) 0.053 grams

c) 5.4 decigrams

d) 2300 milligrams

Step-by-step explanation:

a)

To convert centigrams to grams you have to divide by 100.

40 centigrams = \frac{40}{100} grams

                                        =0.4 grams

b)

To convert milligrams to grams you have to divide by 1000.

53 milligrams = \frac{53}{1000} grams

                                        =0.053 grams

c)

To convert grams to decigrams you have to multiply by 10.

0.54 grams = 0.54*10 decigrams

                                        =5.4 decigrams

d)

To convert grams to milligrams you have to multiply by 1000.

2.3 grams = 2.3*1000 milligrams

                                        =2300 milligrams
