Solve the top equation to get on variable on one side
2x-y=6
-y=-2x+6
y=2x-6
then plug in the coordinate for x and y for both equations. if both equations are true then it’s a solution
2=2(2)+6
2=10
4+2=6
so it’s not a solution
Answer:
0.34
Step-by-step explanation:
Do the inverse operation so;
0.034 / 1/10 = 0.34
Now go back and subsitute,
0.34 * 1/10 = 0.034
Answer:
45.8 degrees
Step-by-step explanation:
We know that the temp before take off is 57.9
We also know the temp decreases every 1,000 feet so
if we are 11,000 feet in the air and divide that 11000/1000=11
We know that the temp drops 11 times
11x1.1=12.1
57.9-12.1=45.8 degrees
Your answer is ab -c
multiply both sides by B
Then subtract C
Michelle's result shows f(2) = -13, selection C.
