16, because all the other numbers are odd and 16 is even
Answer:
n = -1
Step-by-step explanation:
-8n + 4 (1 + 5n) = -6n - 14
-8n + 4 + 20n = -6n - 14 Distribute
12n + 4 = -6n - 14 Combine Like Terms
18n + 4 = -14 Add 6 on Both Sides
18n = -18 Subtract 4 on Both Sides
n = -1 Divide Both Sides by 18
Answer:
2x^2 + 3x + 2
Step-by-step explanation:
Like terms must have exactly the same variables and exponents on the variables.
2x^2 is not a like term to any other term, so it cannot be combined.
3x is not a like term to any other term, so it cannot be combined.
3 and -1 have no variable, so they are like terms and can be combined.
2x^2 + 3 + 3x - 1 =
= 2x^2 + 3x + 3 - 1
= 2x^2 + 3x + 2
Answer:
Y=-6x+7
Step-by-step explanation:
Use the formula change in Y over change in X which is equal to - 6then calculate
Answer:
Step-by-step explanation:
y-x=0.7
y=x+0.7, so lets plug in that into the expressions instead of y
1)
(y-x)=
x+0.7-x=
x+0.7+(-x)=
x+(-x)+0.7=
x-x+0.7=
0.7
2)
(x-(x+0.7))/((x+0.7)-x)=
(x-x+0.7)/(x+0.7-x)=
(x-x+0.7)/(x+0.7+(-x))=
(x-x+0.7)/(x+0.7+(-x))=
(x-x+0.7)/(x+(-x)+0.7)=
(x-x+0.7)/(x-x+0.7)=
0.7/0.7=
1
