Answer:

y = 3x -8

Step-by-step explanation:

The point-slope form of the equation of a line can be a useful place to start.

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y +20 = 3(x +4) . . . . with given numbers filled in

Answer:

Rise=2 Run=1 type of slope is positive slope is 2 y int is 1 and the equation is y=2x+1

Step-by-step explanation:

1. First you need slope, slope is y1-x1/x2-y2 so then you get 4/2 which is 2, we also know rise/run so rise is 2

2. 2/1 so run is 1

3. its positive since slope is positve

4. y int is when x is 0 and y has value so y int is 1

5. y=2x+1 since slope and y int

A glass holds 1over6 liter of liquid.How many glasses of liquid are in 4 liters

Answers

Answer:

24 glasses

Step-by-step explanation:

If a glass holds 1/6 liters of liquid, that means that 6 of them can hold one liter

1/6 * 6 = 1

and if 6 of them can hold 1 liter, that means 24 of them can hold 4 liters

6 * 4 = 24

Cars A and B leave the same place and travel in the same direction along a straight road. Car A travels at 60 km/h and car B travels at 72 km/h. After how long will they be at 8km apart?

Answers

Answer:

Car A: 8 minutes

Car B: 6.67 minutes

Step-by-step explanation:

Car A: 60km evrery hour so,

1 km every minute, so he will be in 8km in 8 minutes.

Car B: 72km per hour so,

72/60 = 1.2 = 1.2 km per minute.

8/1.2 = 6.6666666666667 which is about 6.67 to the nearest hundredth.

Answer:

40 min

Step-by-step explanation:

Car A is traveling at 1 km/min (60/60)

Car B is traveling at 1.2 km/min (72/60)

Car B gains .2km on Car A for every minute they drive.

8km/.2 = 40

To multiply a decimal number by 102, move the decimal point

Answers

Answer:

two digits to the right

Step-by-step explanation:

When multiplying a decimal by 102 you would need to move the decimal point two digits to the right. This is because we are multiplying by a hundred number. When multiplying any whole positive number by a decimal, we need to move the decimal point to the right one less than the amount of digits that the positive whole number has. For example, a thousand (1000) has 4 digits so we move the decimal point of the product to the right by 3.

Examples:

102 * 0.02 = 2.04

1000 * 0.02 = 20

10000 * 0.02 = 200

Mary Jo spends $1,450 to buy stock in two companies. She pays $15 a share to one of the companies and $20 a
share to the other. If she ends up with a total of 90 shares, how many shares did she buy at $15 a share and how
many did she buy at $20 a share?

Answers

Answer:

she bought 70 shares of the $15 shares

she bought 20 shares of the $20 shares

Step-by-step explanation:

this would be solved using simultaneous equation

let a = $15 shares

b = 20 shares

a + b = 90 equation 1

15a + 20b = 1450 equation 2

Multiply equation 1 by 15

15a + 15b = 1350 equation 3

subtract equation 3 from equation 2

5b = 100

b = 20

substitute for b in equation 1

20 + a = 90

a = 70
