The system is "inconsistent".
The first and last equations describe parallel lines:
x +2y +3z = 12
x +2y +3z = 60
There are no values of x, y, and z that can satisfy both equations.
Answer:
x=3 and y=4
Step-by-step explanation:
solve x-y=-1 to get x:
x−y=−1
x−y+y=−1+y(Add y to both sides)
x=y−1
Substitute y−1 for the x value in x+2y=11:
3y/3=12/3
y=4
Substitute 4 for the y value in x=y−1:
x=y−1
x=4−1
x=3
so y=4, and x=3
Answer:
I’F’ = 21
Step-by-step explanation:
To find the length of I’F’
We perform the dilation on IF using the given dilation factor
All we have to do here is to multiply the length of IF by the dilation factor
We have this as ;
28 * 3/4 = 21
The y-intercept is (0,-11), which is option C.
