Answer:
y + 11 = - 2(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 2 and (a, b) = (- 1, - 1), thus
y - (- 1) = - 2(x - (- 1)), that is
y + 1 = - 2(x + 1)
Answer:
13, 0.325, and -142
Step-by-step explanation:
13 because the number terminates, 0.325 because the decimal terminates, and -142 because it is a negative integer, the rule with rational numbers is that they must follow a pattern if continuing or terminate or be a positive or negative integer. For example, pi is an irrational number so is 0.45623... and 50--√.
Answer:
Yes there is, and it is 4.99.
Step-by-step explanation:
The constant of proportionality (let's call it 
) will relate the number of books bought 
and their cost 
in the following way:
For the 12 books:
And for the 21 books:
The for the two purchases is the same, thus there is a constant of proportionality between the two purchases.
P.S: is the price per book.
Multiply (3pi/4) by (180/pi), the angle in degrees is 135 degrees.
