yes i agree with her because elimination method is more simpler and shortest method to solve system of equations.
elimination method use to multiply of both equation in order to balance the variable x or y and then equate them.
example
x+2y=7 .....equation 1
x-3y=14 .......equation 2
so you can multiply equation 1 by -1 in order to equate x and get the value of y by saying equation 1 minus equation 2.
try this answer good luck
Answer:
Answer:<u> 1/2 </u>
Step-by-step explanation:
Given : Figure B is a scaled copy of Figure A.
We know that the scale factor is the ratio of the corresponding sides of two similar figures.
From , the graph we assume that that one point = one unit of length.
Then, the dimension of one side of figure A = 4 units and the dimension of corresponding side of Figure B = 2.
Then, the scale factor is given by:
k = 2/4 = 1/2
Hence, the scale factor is <u>1/2</u>
Answer:
<h3>f(1)=-2.</h3>
Step-by-step explanation:
We are given a graph with four points on the graph with coordinates as following:
(-3,0)
(-2,2)
(0,1) and
(1,-2).
We need to find the value of function f(x) at x=1 that is f(1) =?
That means we need to find the y-coordinate of the point, where x coordinate is at 1.
We can see tat fourth point on the graph (1,-2) has x-coordinate at 1 and y-coordinate at -2.
<h3>Therefore, f(1)=-2.</h3>
