First, you would add 9x to both sides so that you get:
x^2 + 9x + 20 = 0.
Then, you want to factor. You want coefficients of x that add to 9 and have the constants add to 20:
(x + 5) * (x + 4) = 0
The answer is (C).
Answer:
7/4 OR 1 3/4
Step-by-step explanation:
49/10 divided by 14/5
49/10 multiplied by 5/14
49x5 / 10x14
245/140
simplified or cancelled out to
7/4 OR 1 3/4
Answer:
x = 41
Step-by-step explanation:
<u>Subtract the lower term in both sides</u>
3x - x = 2x
2x - 84 = -2
<u>Add 84 in both sides</u>
84 -2 = 82
2x = 82
<u>Divide 2 in both sides</u>
2x/2 = x
82/2 = 41
<u>Simplify</u>
x = 41
<u>Answer</u>
x = 41
Answer:
Step-by-step explanation:
The general slope-intercept equation is: y = mx + b.
In this equation, "m" is equal to the slope and "b" is equal to the y-intercept.
Since the slope is "1/2", then this is the "m" value.
Since the line passes the y-axis at "8" when x = 0, then "b" must be "8".
Therefore, the equation of the function in slope-intercept form is .
Answer:
Step-by-step explanation:
The initial value is the value when x = 0.
For x = 0,
