Answer:
The answer is A.
Step-by-step explanation:
So we have the two equations:
To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:
Now, we can substitute this into the first equation. Therefore:
In y = mx + b form, the slope will be in the m position and the y int will be in the b position
y = -2x + 2....slope = -2 and y int = 2
y = -2x - 3.....slope = -2 and y int = -3
when u have 2 lines that both have the same slope but different y intercepts, u have parallel lines with no solution because ur lines never intersect.
so ur answer is : no solutions or 0 solutions
You can use elimination
7x - 3y = 4
-10x + 3y = 2
Add both equations
-3x = 6, x = -2
Plug in -2 for x in one equation
7(-2) - 3y = 4
-14 - 3y = 4
-3y = 18, y = -6
Solution: x = -2, y = -6
Answer:
1. 5 <3rd side<21 2. 12.1<3rd side<35.1
Step-by-step explanation:
;-)
Answer:
3rd
Step-by-step explanation:
The definition of an inverse function is that h(f(x)) = x
Therefore, all we need to do is to plug x + 3 into your option choices to find which one returns x.
Therefore, the third option gives you:
x+3-3 = x
