Answer with explanation:
1. x+0=x
0 is the identity element.When number is added to identity the resultant is number.
Option D : Identity
2.
3x-2=60
Adding 2 on both sides
→3x-2+2=60+2
→3x=62
Dividing by 3, on both sides
Option (B.)→ Add 2 . Divide by 3
3.
y> -2,
y=(-2, Infinity)
So, -3 is not the solution of ,y>-2.
Option A: False
4.
The equation in slope-intercept form, is, y = mx + b.
4x-2y=10
4x=2y+10
2y=4x-10
Dividing by 2, on both sides
y=2x-5
Option A:→y=2x-5
5.
The equation of line is
y=2x-11
We have to check whether point (3,0) lies on the line or not.
LHS=y=0
RHS=2x-11
=2 ×3-11
=6-11
= -5
So, point (3,0) does not lie on the line,→y=2x-11.
Option B : False
6.
Slope of line joining the points (-2,-1) and (3,4) is
Slope=1
Option A
7.
When solving a system of equations, you are finding the
Option C: Intersection point
8.
The function g(x) is g(x)= (3x)^2
<h3>How to solve for g(x)?</h3>
The complete question is in the image
From the graph in the image, we have:
f(x) = x^2
The function f(x) is stretched by a factor of 3 to form g(x).
This means that:
g(x) = f(3x)
So, we have:
g(x)= (3x)^2
Hence, the function g(x) is g(x)= (3x)^2
