Answer:

1. x+y=16 (the y’s cancel because they are inverse operation)

  x-y=10 (x+x=2x and 16+10=26 now the equation is 2x=26 now just solve for x by dividing 2 on both sides 26/2=13)

YOUR NOT DONE YET: (Now that we've found x let's plug it back in to solve for y.Write down an original equation I’m using x+y=16 And Substitute 13 for x)

the equation is 13+y=16 now subtract 13 on both sides and you should get y=3

2. for number 2 it’s the same as number 1

3. in this one the x will cancel each other because they are inverse)

(for the rest please use the website: Mathpapa it’s very helpful I would do more but I’m running out of time hopefully you can use this as a example to do the rest I’m really sorry I couldn’t do the rest)

Given that A varies directly as B and inversely as C and that; A=12 when B=3 and C=2. Find B when A=10 and C=1.5​
maria [59]

Answer:

B = 1.875

Step-by-step explanation:

given that A varies directly as B and inversely as C then the equation relating them is

A = \frac{kB}{C} ← k is the constant of variation

to find k use the condition A = 12 when B = 3 and C = 2 , then

12 = \frac{3k}{2} ( multiply both sides by 2 to clear the fraction )

24 = 3k ( divide both sides by 3 )

8 = k

A = \frac{8B}{C} ← equation of variation

when A = 10 and C = 1.5 , then

10 = \frac{8B}{1.5} ( multiply both sides by 1.5 )

15 = 8B ( divide both sides by 8 )

1.875 = B

What is <br> the equation of the line that passes through the points (-6,6) and (-1,-9)
IgorLugansk [536]

Answer:

The answer to the question provided is y = -3x - 12.

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

y = mx + b

❃Incase you also forgot, what the slope formula is ☟

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

➊ First: We are going to be solving for the slope.

m = \frac{  - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3

➋Second: We find the y-intercept.

y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{  - 18 =  - 18 \: \: \: \: \:  \:  \:  \:  \:  \:  \:  \: }{ - 12 = b}

➌Third: Plug in.

y =  - 3x - 12
