Could it be an Imaginary number?
The correct answers to the question above includes:
a=.1
b=20.775
c=0.02
Answer:
where are the answers/histograms we can choose from?
Step-by-step explanation:
Answer:
The best estimate solution to the system of equations is (0, 3)
Step-by-step explanation:
we have
y=14x-2 ------> equation A
y=-2x+3 -----> equation B
Solve the system by elimination
Multiply the equation B by 7 both sides
(7)y=(7)(-2x+3)
7y=-14x+21 -------> equation C
Adds equation A and equation C
y=14x-2
7y=-14x+21
-----------------
y+7y=-2+21
8y=19
y=19/8
Find the value of x
y=14x-2
19/8=14x-2
19=112x-16
112x=19+16
112x=35
x=35/112
so
The solution is the point (35/112,19/8)
Convert to decimal number
(0.3125,2.375)
therefore
The best estimate solution to the system of equations is (0, 3)
Answer:
15 minutes more, as 60-45mins = 15 minutes.
Step-by-step explanation:
Distance = 30 miles
Speed = 30mph = 1 hr
Compared to Distance 30 miles
Speed = 40mph = 3/4 of 60mins = 45 mins.
1hr = 60mins = 60-45 = 15 minutes.
