Use the slope formula to find the missing coordinate: R(0,_), S(-4,2) m=5
Delicious77 [7]

Answer

The missing value is 22

step-by-step explanation

The slope formula is

m =  \frac{y_2 - y_1}{x_2 - x_1}

From the question,

m=5

x_2=-4

y_2=2

and

x_1=0

We substitute these values to get,

5=  \frac{2 - y_1}{ - 4- 0}

Simplify

5=  \frac{2 - y_1}{ - 4}

5 \times  - 4=2 - y_1

- 20=2 - y_1

- 20 - 2=- y_1

22= y_1

y_1 = 22

The missing value is 22

Roberto wants to display his 18 sports cards in an album . Some pages hold 2 cards and others hold 3 cards .
nexus9112 [7]

Answer:

Step-by-step explanation:

Assuming Roberto wants to completely fill each page that he puts cards in, this function describes the number of 2-card pages, a, and 3-card pages, b.

2a + 3b =18

Ricardo can fill up 9 2-card pages, and 6 3-card pages.

a=9, b=0

We must add 2 3-card pages at a time,so that we have an even number for the 2-card pages:

a=6, b=2

Add 2 to b once more:

a=3, b=4

One more time:

a=0, b=6:

Thus, Ricardo can display his figures in the following page combinations:

a=9, b=0

a=6, b=2

a=3, b=4

a=0, b=6

Remember that a= number of 2-card pages and b=number of 3-card pages

There are 4 different ways that Ricardo can arrange his figures in terms of what kind of pages he uses.

-6(2+n) is greater than 72
Hitman42 [59]

Answer:

n > -14

Step-by-step explanation:

Firstly, you use the distributive property;

-12 - 6n > 72

Then, since 12 is negative, you add 12 to both sides;

-12 - 6n > 72

+12           +12

-6n > 84

Then you divide both sides by -6 to get n > -14.


Shoot, hold on; this is an edit; did you mean that 72 is greater than -6(2 + n) or did you accidentally flip the sign in the picture? Hopefully I did what you needed.
