Answer: B (2,1)

You know what y is (x-1) so you substitute that for y in the other equation.

3x+ ((4)(x-1))=10

3x+4x-4=10

7x=14

x=2

Then put x=2 into y=x-1

y=2-1

y=1

How to solve for -4n+4>48

Kryger [21]

Answer:

n<-11

Step-by-step explanation:

It's a bit different since it's an inequaltiy and not an equation, but here's the explanation:

-4n+4>48

Subtract 4 from both sides

-4n>44

<em>Remember when multiplying or dividing by negatives you have to flip the inequality sign.</em>

Divide both sides by -4.

n<-11

Hope this helps!

Need help please!!!!!!!!!!!

Answer:

Step-by-step explanation:

The vertical asymptote is 3 so our constant add to our function e^x is 3.

So naturally that leaves us which Only Option A.

Option A is the option because in the parent function, e^x, the y intercept occurs at (0,1). After the vertical shift upwards 3, the graphs becomes

${e}^{x} + 3$

We then have to move to the left 2 units to we add 2 to the x variable

${e}^{x + 2} + 3$
