Answer:
If two distinct planes intersect, then their intersection is a line. If two distinct lines intersect, then they intersect in exactly one point. If there is a line and a point not in the line, then there is exactly one plane that contains them. If two distinct lines intersect, then they lie exactly in one plane.

Answer:
3n + 3
Step-by-step explanation:
Mia is correct
When n= 1 , 3n + 3 = 3*1 + 3 = 3 + 3 = 6
When n =2, 3n + 3 = 3*2 + 3 = 6 + 3 = 9
When n = 3 , 3n +3 = 3*3 + 3 = 9 + 3 = 12
When n = 4, 3n + 3 = 3*4 + 3 = 12 +3 = 15
Answer:
Step-by-step explanation:
-A fair die has 6 faces, a sample space of 6 and each space has a probability of 1/6:
#The probability of 3 in the red die;
#The probability of 3 in blue die:
The probability of a 3 in both dice is the product of the individual probabilities:
Hence, the probability of a 3 in both dice is
Answer:
Equation: y=$3(x)+$30
Total cost $42
Step-by-step explanation:
Calculation to Find the total cost of 4 hours at the aquarium using this formula
y=mx+b
Where,
y intercept=Total cost
m=$3 per hour
b=$30 Tickets
x=4 hours
Let plug in the formula
First step is to form the equation
y=$3(x)+$30
Second step is to substitute 4 hours for m and b
y=$3(4)+$30
Hence:
y=$12+$30
y=$42
Therefore the equation will be y=$3(x)+$30 while the total cost of 4 hours at the aquarium will be $42
Answer:(x² + 14x)/(9x²)
Step-by-step explanation:
Explanation:To do this calculatio process:The first term: 2x/x² = 2/x.Then: (2/x) + (x - 4)/(9x).We should common the denominator by multiplying the denominators of the two terms (9x)(x) = 9x² and dividing each denominator by the common denominator.So, it will be equal:[(2)(9x) + (x - 4)(x)]/9x² = (18x + x² - 4x)/9x² = (x² + 14 x)/9x².
