The measure of BDA is 40 degrees
Multiplying fractions, unlike adding them, does not require you to find a common denominator. Simply multiply the numerator and denominator and simplify if you have to. In this case, it's .
-->
A negative multiplied by a positive is still negative, so this becomes .
The answer would be f(x)=9 because when you substitue the 3 in for 'x' you then square the 3.
Hope this helps!
Answer:
Step-by-step explanation:
The equation of a line is given in the form
Where
m is the slope with formula
and
b is the y-intercept [y axis cutting point of line]
Given the two points (0, -2) and (6,0),
x_1 = 0
y_1 = -2
x_2 = 6
y_2 = 0
Now, we find m using formula:
Now we have
Finding b, we plug in any (x,y) point. Lets put (6,0) and find b:
Thus,
equation of line =
Answer:
5
Step-by-step explanation:
2x + 3y = 12
2x - 2y = 2 // subtract second equation from first
5y = 10
y = 2
x = (2 + 2y) / 2 = y + 1 = 3
x + y = 5
