by 6780
Step-by-step explanation:
That's a line:
g(x)=0.5*x-1, pick up some x, and get the y.
For instace: x=0, g(0)=y=-1, x=2, g(2)=y=0.
Two pints are enough for a line.
Answer:
The correct answer is a) 16
Step-by-step explanation:
To find this first distribute the interior negative to both terms in the parenthesis.
9 - {x - (7 + x)}
9 - {x - 7 - x}
Now simplify the like terms.
9 - {-7}
Now distribute the negative once again.
9 + 7
And complete the indicated operation.
16
Answer: 42
Step-by-step explanation:
Complementary means they add up to 90 degrees
so 90-48=42
Use the distributive property to multiply 1/5 by 4-3x.
Multiply 1/5 and 4 to get 4/5.
Multiply 1/5 and -3 to get -3/5.
Use the distributive property to multiply 1/7 by 3x-4.
Multiply 1/7 and 3 to get 3/7 & 1/7 × -4 to get -4/7.
Subtract 
from both sides.
Combine 
and 
to get 
.
Subtract 4/5 from both sides.
The least common multiple of 7 and 5 is 35. Convert -4/7 and 4/5 to fractions with denominator 35.
Because 
and 
have the same denominator, subtract them by subtracting their numerators.
Subtract 28 from -20 to get -48.
Multiply both sides by 
, the reciprocal of 
.
Multiply 
by by multiplying the numerator by the numerator and the denominator by the denominator.
Carry out the multiplications in the fraction 
.
Reduce the fraction 1680/1260 to its lowest terms by extracting and cancelling out 420.
