Answer:
a: no solutions
b: (2, 3)
Step-by-step explanation:
a:
In both equations, the slope of x is the same, but the y-intercept is not, which means they are parallel. Therefore, this system of equations has no solutions.
b:
Since both of the equations are equal to y, we can set them equal to each other:
We can solve by factoring (by finding a number that multiplies to 4 and adds up to -4):
(x-2)^2 = 0
x = 2
Now, to find y, plug-in x to any of the equations:
y = 2*2-1 = 3
Therefore, the solution to this system of equation is (2, 3)

Answer: 7 Switches will be made.
Step-by-step explanation:
number of switches
number of switches
- however you cannot have a fraction of a switch so you must round it to a whole number, which in this case is 7.
Answer:
6%
Step-by-step explanation:
Let T= truck
C= Car
We are looking for the probability that someone owns a truck given that they own a car
or
P(T|C)
The conditional probability formula is as follows:
P(T|C)=(T∩C)/C
plugging in numbers..
.04/.63=6.3492% which rounds to 6%
No it does not equal 4 fifths
(3-6)/(8-2)+(7/2)
Do what is in the parenthesis first.
-3/6+3.5
-0.5+3.5=3
Therefore, your answer is 3
Hope this Helps!
