The drop down menus are not provided. However, I will help get the solution of the system of equation which is the requirement of the question.

<u><em>Answer:</em></u>
(3,14) and (-2,-1) are the solutions of the system

<u><em>Explanation:</em></u>
<u>The first equation given is:</u>
y = x² + 2x - 1 .........> equation I
<u>The second given equation is:</u>
y - 3x = 5
<u>This can be rewritten as:</u>
y = 3x + 5 ..........> equation II

<u>Equate equations I and II and solve for x as follows:</u>
 x² + 2x - 1 = 3x + 5
x² + 2x - 1 - 3x - 5 = 0
x² - x - 6 = 0
(x-3)(x+2) = 0

either x-3 = 0 .........> x = 3
or x+2 = 0 ...........> x = -2

<u>Now, we get the values of y by substituting in equation II as follows:</u>
At x = 3:
y = 3x + 5 
y = 3(3) + 5
y = 14
The first solution is (3,14)

At x = -2:
y = 3x + 5
y = 3(-2) + 5
y = -1
The second solution is (-2,-1)

Hope this helps :)

**WILL MARK BRAINLIEST AND THANK YOU**
omeli [17]

A is correct because f(1)=3^1+1 so f(1)=4 and g(x)=4 so f(x)=g(x)

B is also correct because the ordered pair we get is (1,4) and this is in quadrant 1

C is incorrect

D is incorrect

E is incorrect

Ans: A and B are correct

WILL GIVE BRAINLIST
borishaifa [10]

Answer:

option: C is correct.

Step-by-step explanation:

since, we are given a parent function f(x) as: f(x)=x.

We are asked to find what  change will occur in the function when the parent function f(x) is replaced by f(9x).

let g(x) be the function formed by replacing f(x) with f(9x) i.e.

g(x)=f(9x)=9x.

clearly the slope of the function g(x)=f(9x) is 9.  ( since on comparing the equation with the slope intercept form y=mx+c; where m is the slope of the line and c is the y- intercept).

whereas the slope of the function f(x)=x is 1.

Hence there is an increment of slope by a factor of 9.

Hence, option C is correct.
