3=-m+b -2=2m+b find m and b

Mathematics
1 answer:
kiruha [24]3 years ago
4 0

Answer:

b = 4/3

m = -5/3

Step-by-step explanation:

3=-m+b

-2=2m+b

Subtract the second equation from the first

3=-m+b

-( -2=2m+b)

------------------------

  3=-m+b

+ 2=-2m-b

------------------------

5= -3m +0b

Divide by -3

5/-3 = -3m/-3

-5/3 = m

Now we can find b

3=-m+b

3 = - (-5/3) +b

3 = 5/3 +b

Subtract 5/3 from each side

3 -5/3 = b

9/3 - 5/3 = b

4/3 =b

Each tick on the graph represents a single unit.

Thus, counting the ticks, we see that the graph starts at x=2. We also see that the graph ends at x=5.

Thus, the domain is 2 \leq x \leq 5

Let me know if you need any clarifications, thanks!

6(6n – 6) &lt;-108<br><br> Idk how to solve this help
Allushta [10]

Answer:

\Huge \boxed{N

Step-by-step explanation:

To solve this problem, first you have to isolate it on one side of the equation. To solve this problem, division property of equality is divide both sides of an equation by the same number doesn't change the equation.

First, divide by 6 from both sides.

6(n-6)/6<-108/6

Solve.

-108/6=-18

6n-6<-18

Next, add 6 from both sides.

6n-6+6<-18+6

Solve.

-18+6=-12

6n<-12

Then, divide by 6 from both sides.

6n/6<-12/6

Solve.

-12/6=-2

As a result, the correct answer is n<-2.
