Answer:
(0,4)
(2,2)
Step-by-step explanation:
y=x^2-3x+4
x+y=4
the second one can be rewritten as y=4-x
so the system becomes
y=x^2-3x+4
y=4-x
therefore 4-x = x^2-3x+4
that is x^2-2x=0
we can write it as x(x-2)=0 a product is = 0 when one of its factors = 0
so the solutions for x are: x=0 and x-2= 0 that means x=2
to get y you simply use 0 and 2 as value of x for any of the two equations
and you get y=4 and y=2 respectively
No because the number has to be between 1 and 10 so it should be 2.6x10^3
The problem gives you the time in hours, but you're looking for your answer in minutes so change 1/10 of an hour to minutes first. To do this, multiply 1/10 by 60 to get 6 minutes. Since there are 4 quarters in a whole, multiply 6*4. It would take her 24 minutes to drink the whole shake
Answer:The equation wth x in the information can be written as
1/2 x = 38.5 , Upon solving, the number = 77
Step-by-step explanation:
Let the number Sara was thinking about be x
halving the number to get an answer = 38.5 can be expressed as
1/2 X = 38.5
The equation with x in the information can be written as
1/2 x = 38.5
solving it becomes
1/2 x= 38.5
x = 38.5 x 2
x=77
The number Sara was thinking about = 77
Answer:
It is c)1/2
Step-by-step explanation:
Since its rising its postive
And the rise is 1 and the run is 2 so the slope is 1/2
