Answer:
y = - 
x - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 5x + 9y + 18 = 0 into slope- intercept form
Subtract 5x + 18 from both sides
9y = - 5x - 18 ( divide all terms by 9 )
y = - x - 2 ← in slope- intercept form
with m = -
Parallel lines have equal slopes, thus
y = - x + c ← is the partial equation
To find c substitute (- 5, - 7) into the partial equation
- 7 = 
+ c ⇒ c = - 7 - = -
y = - x - ← equation of line
Answer:
1 is a
2 is b
Hope that helps!!! tysm!! :3
Answer:
x= -12
Step-by-step explanation:
move variable to left and change its sign
= 4x - 20 = -68
move constant to the right and change its sign
= 4x = -68 + 20
calucate the sum
= 4x = -48
divide both sides of the equation by 4
x= -12
Answer:
$0.90
Step-by-step explanation:
7.20/8 = $0.90
Answer:
1. True
2. False.
3. True.
Step-by-step explanation:
1. The total area within any continuous probability distribution is equal to 1.00: it is true because the maximum probability (value) is one (1), therefore, the total (maximum) area is also one (1).
<em>Hence, for continuous probability distribution: probability = area</em>.
2. For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: False because it has an infinite number of possible values, which can not be counted or uncountable.
<em>Hence, it cannot be computed. </em>
3. For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: True because it has a finite number of possible values, which are countable or can be counted.
<em>Hence, it can be computed. </em>
