Hello,
Addition : no because -1+(-1)=-2 not in set.
Division : no because 1/0 is not in the set :infinity
Multiplication yes: {-1,0,1}*{-1,0,1}={-1,0,1}
Substraction: No because (-1)-(1)=-2 not in set.
Answer C
Answer:
The answer is b. 979,000
Step-by-step explanation:
If you move the decimal right five time from 9.79 you would get 979,000
Answer:
y = - 2x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange y + 2x = m into this form by subtracting 2x from both sides
y = - 2x + m ← in slope- intercept form
with slope m = - 2
Parallel lines have equal slope, thus
y = - 2x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = - 8 + c ⇒ c = 3 + 8 = 11
y = - 2x + 11 ← equation of line
Answer:
a = 8
Step-by-step explanation:
4 : 3 = a : 6
Cross multiply
4*6 = a * 3
a = 4 * 2
a = 8
