Step-by-step explanation:
7/7 x 9/10
1 x 9/10 = 9/10
Answer:
6
Step-by-step explanation:
18-3 = 15. 15 divided by 2.5 is 6. Hope this helps!
Additive inverse is the negative of the number, i.e. what you add to the number to get zero.
So the additive inverse of number b is - b
Additive inverse of 4 is - 4.
Then, you can verify the subtraction is the same that add the additive inverse.
For example subtracting 4 from 10 (10 - 4) is the same that adding -4:
10 - 4 = 10 + (-4).
Then given any expression if you have to subtract other expressión you just add the addive inverse of the second expression.
For example: given A(x) = x^2 + 3x + 5 and B(x) = 2x + 4
Find A(x) - B(x) = A(x) + [-B(x)]
=> x^2 + 3x + 5 + (-2x -4) = x^2 + 3x - 2x + 5 - 4 = x^2 + x + 1
Slope: (6-(-6))/(2-(-4))=12/6=2
y=2x+b
next, find b: 6=2*2+b =>b=2
so the equation is y=2x+2
