We can use the number line as a model to help us visualize adding and subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations.
To add integers having the same sign, keep the same sign and add the absolute value of each number.
To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.
Subtract an integer by adding its opposite.
-4b - 2c =
(-4 × 2.5) - (2 × 3)
-10 - 6
= -16
So, -4b - 2c = -16
Hope this helps and let me know if anymore help is needed!!
Answer:
8999 integers have four distinct digtis between them
M/_A= 120°
m/_B=30°
m/_C= 100°
sum of all the angles=120+30+100 = 250°
Answer:
Equation for line h y = -2x +7
Step-by-step explanation:
Since the lines are parallel, their slope (m) must be the same.
Since they are in the form y=mx+b lets plug in the x and y values of line h.
y=mx+b
9= -2(-1) +b
9 = 2 + b
b = 7
lets plug this into the original equation.
y = -2x +7
