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
5x-29>-34
5x>-5
x>-1
x<1
2x+31<29
2x<-2
x<-1
x>1
Answer:
-60 3/4m
Step-by-step explanation:
The diver first dives down 50 1/4m, which is represented by the -50 1/4m. He then descends another 10 1/2m down. So -50 1/4m - 10 1/2m.
-50-10=-60
-(1/4)-(1/2)= (1/4)+(1/2)
(1/4+1/2)=(2/8+4/8) you can only add with the same denominators.
=6/8 (simplifies down to 3/4)
