Answer:
-10
Step-by-step explanation:
22-12=10
CHECK:
-12+(-10)=-22 (correct, and proven)
Answer:
1/12, 1/10
Step-by-step explanation:
P(Bead bracelet and red shoes) - 3/3 x 2 x 2
3/12=1/4 for bead bracelet
Red shoes - 1/3
Total probability for P(Bead bracelet and red shoes=1/4 x 1/3=1/12
P(Elastic bracelet and black shoes)
2/3 x 2 x 2
2/12=1/6 for elastic bracelet
Black shoes - 3/5
Total probablility for P(Elastic bracelet and black shoes)=1/6 x 3/5=3/10=1/10
Hope I helped!
Answer: 40
Step-by-step explanation: Multiply by the reciprocal (flip the fraction 1/4), and the new equation is 10*4, which is 40
Answer: Option D
Step-by-step explanation:
If the graph of the function 
represents the transformations made to the graph of 
then, by definition:
If 
the graph moves vertically upwards.
If 
the graph moves vertically down
If 
The graph moves horizontally h units to the left
If 
The graph moves horizontally h units to the right
In this problem we have the function 
and our parent function is 
therefore it is true that 
and 
Therefore the graph of is <u><em>moves horizontally 3 units to the left</em></u>. Also, as then the graph <u><em>moves vertically 7 units down
</em></u>
Therefore the answer is the option D
<span> x – 3y = 9 ------------ (1)
1/5x - 2y = -1---------- (2)
(1):
x - 3y = 9
x = 9 + 3y ----------- (1a)
(2):
</span>1/5x - 2y = -1
x - 10y = -5 --------- (2a)
Sub (1a) into (2a):
9 + 3y - 10y = -5
9 - 7y = -5
-7y = -5 - 9
-7y = -14
7y = 14
y = 2 ---------- Sub into (1a)
x = 9 + 3y
x = 9 + 3(2)
x = 9 + 6
x = 15
Ans: x = 15, y = 2
