Which equation represents the line that passes through the point (-2,5) and has a slope of - 3

2 answers:

8 0

Answer: y= -3(-2-x) + 5

The slope equation is y=mx + b or point slope equation is y1-y=m(x1-x)

If you already have a point, using point slope form would be way faster and easier.

Point (-2,5) slope of -3

Plug into equation of y-y1=m(x1-x)

y - 5 = -3(-2- x) then add the 5 to the right side of the equation then your answer will be

y= -3(-2-x) + 5

Hello,

So 45 divided by 12 would get you 3.75. If I were to convert this in a mixed number, I would get me 2 1/2. So your answer is D

Hope this helps.

The ratio of money in Terry's bank account to Faye's bank account was 3:5.

inn [45]

Answer:

Terry had £780 initially and Faye had £1300

Step-by-step explanation:

System of Equations

We'll call the following variables:

x = Terry's balance in his bank account

y = Faye's balance in her bank account

The initial relation between them is:

$\frac{x}{y}=\frac{3}{5}$

Cross-multiplying:

5x = 3y [1]

If Terry put £220 in his account he had x+220 and if Faye withdrew £300 from her account, she had y-300. Both quantities are equal, thus

x + 220 = y - 300

Subtracting 220:

x = y - 520 [2]

Substituting in [1]

5(y - 520) = 3y

Multiplying:

5y - 2600 = 3y

Adding 2600 and subtracting 3y:

2y = 2600

Dividing by 2:

y = 1300

From [2]:

x = 1300 - 520

x = 780

Terry had £780 initially and Faye had £1300
