The sum of 2 integers with different signs is the difference between the two integers, the sign will be the same as the sign of the bigger number.
The m variable is the slope of the line and controls its 'steepness'. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept - the point where the line crosses the y axis.
example 1
y = mx + b
m = slope b = y-intercept
y = 3x - 1
m = 3 and b = -1
example 2
y = b + m<em>x</em><em> </em>
b = y-intercept m = slope
y = 5 - 1/2x
m =- 1/2 and b = 5

Answer:
13 y^2 - 13 y + 11
Step-by-step explanation:
Simplify the following:
15 y^2 - 2 y^2 + 2 y - 15 y + 4 + 7
Grouping like terms, 15 y^2 - 2 y^2 + 2 y - 15 y + 4 + 7 = (15 y^2 - 2 y^2) + (-15 y + 2 y) + (7 + 4):
(15 y^2 - 2 y^2) + (-15 y + 2 y) + (7 + 4)
15 y^2 - 2 y^2 = 13 y^2:
13 y^2 + (-15 y + 2 y) + (7 + 4)
2 y - 15 y = -13 y:
13 y^2 + -13 y + (7 + 4)
7 + 4 = 11:
Answer: 13 y^2 - 13 y + 11
Answer:
"sixty-three hundredths of a Kilometer"
Step-by-step explanation:
Decimal measurements are read based on the place of their digits. In this case, Ajay would read this measurement as "sixty-three hundredths of a Kilometer". This is because the final digit of the decimal form measurement is in the "hundredths" position. One more to the right and it would be in the "thousandths" while one more to the left would be the "tenths"
