Answer:
The correct option is: Both -5 and 1 are true solutions
Step-by-step explanation:
The given expression is:
√c^2+2c-4=√1-2c
By squaring both sides we get:
(√c^2+2c-4)^2=(√1-2c)^2
c^2+2c-4=1-2c
Move all the values to the L.H.S
c^2+2c-4-1+2c=0
c^2+4c-5=0
Now we will perform factorization:
c^2+5c-c-5=0
c(c+5)-1
(c+5)=0
(c+5)(c-1)=0
c+5 = 0 , c-1=0
c= 0-5 , c=0+1
c= -5 , c=1
Thus the correct option is Both -5 and 1 are true solutions....
Answer:-
0
Step-by-step explanation:
h(x) = x^2 + 2x -3
x = 2
h(2) = 2^2 + 2(2) - 3
h(2) = 4 + 4 - 3
h(2) = 8-3
h(2) = 5
x = - 4
h(-4) = (-4)^2 + 2(-4) - 3
h(-4) = 16 - 8 - 3
h(-4) = 16 - 11
h(-4) = 5
========
h(2) - h(-4)
5 - 5
0
Answer:
B
Step-by-step explanation:
Domain is basically x. The left side is connecting with the right side (y).
this is why the domain is B
Hope this helps!
To now the difference you just have to subtract and will give you 1.68
