2x² + 3x -8 = 0
a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73
for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a
So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)
Hopefully helpfull.. ^_^
Answer:
The equation of the exponential function represented by the table will be:

Step-by-step explanation:
We know the equation of exponential function such as

Put x=0, and y=2 in the function


Also x=1, and y=8 in the function


Thus,


Therefore, the equation of the exponential function represented by the table will be:

Answer:
21
Step-by-step explanation:
Answer:
C. x < - 1
Step-by-step explanation:
1. Subtract 6 from both sides.

2. Simplify 5 - 6 to -1.

Therefor, the answer is, x < -1.
Answer:
One proportion
Step-by-step explanation:
A proportion refers to a statement that two different ratios are equal. There are two ways It can be written: since two equal fractions a/b = c/d; or using a colon, a:b = c:d. in view of the fact that the cross products are of both equal to one hundred, we are aware that these ratios are equal and that this is a true proportion.
