Answer:
x= -1/2 = -0.500
x=4
Step-by-step explanation:
2x^2-7x-4=0
2x^2-8x+1x-4=0
2x(x-4)+1(x-4)=0
(2x+1)(x-4)=0
2x+1=0...2x= -1.. x= -1/2 x-4=0 .. x=4
checking the solution
2(-1/2)^2-7(-1/2)=4..... 4=4
2(4)^2-7(4)=4....... 4=4
Answer: the graph farthest to the right is almost correct. If you substitute values for x in the function f(x)= -3√x , the output does not match the curve on the graphs shown.
If you have a choice that includes only a curve to the right of the y- axis, that would be better.
Step-by-step explanation: Square roots of Negative x-values will result in imaginary numbers. Otherwise the graph with the curve passing through coordinates (1,-3) (4,-6) and (9,-9) is a good choice.
(And ask your teacher about the square root of negative numbers on this graph.)
Answer:
9/5
Step-by-step explanation:
solve the original equation for x
-4× + 3 = 1x +(-6)
-1x
-5x + 3 = -6
-3
-5x = -9
/-5
x = 9/5
CHECK
-4(9/5) + 3 = 1(9/5) +(-6)
-21/5 = -21/5
