Answer:
The y intercept is (0,-1)
Step-by-step explanation:
To find the y intercept, let x = 0
y = -x^2 -6x-1
y = -0^2-6(0) -1
y = -1
The y intercept is (0,-1)
The old mean was 51 now the mean is 42.33... (round that to 42) 51 - 42 = 9
Well, it depends if its positive or negative. 2 positive integers will equal a positive, 2 negatives will equal a negative. A negative and a positive will depend.
Answer:
y=-9
Step-by-step explanation:
If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22
We can solve for multiplication first:
4-2y=22
Then we can subtract four on both sides, canceling out the four on the left side:
-2y=18
Now to isolate y, we divide both sides by -2, resulting in the solution:
y=-9
