Answer:
x=1/3 or x=−2
if i can be brainliest that would be great
Step-by-step explanation:
Step 1: Add 2 to both sides.
3x^2+5x−2+2=0+2
3x^2+5x=2
Step 2: Since the coefficient of 3x^2 is 3, divide both sides by 3.
3x^2+5x/3=2/3
x^2+5/3x=2/3
Step 3: The coefficient of 5/3x is 5/3. Let b=5/3.
Then we need to add (b/2)^2=25/36 to both sides to complete the square.
Add 25/36 to both sides.
x^2+5/3x+25/36=2/3+25/36
x^2+5/3x+25/36=49/36
Step 4: Factor left side.
(x+5/6)^2=49/36
Step 5: Take square root.
x+5/6=±√49/36
Step 6: Add (-5)/6 to both sides.
x+5/6+ −5/6=
−5/6±√49/36x=−5/6±√49/36x=
1/3 or x=−2

Answer:
a:
10
b:
-10 and 10
c:
8
Step-by-step explanation:
i could be wrong on c tho
I believe this should just be equal to<span>
9π+5e−<span>(<span>⌊9π+5e⌋</span>)</span>=9π+5e−41</span>
The first element in your sum should be the first digit after the decimal point times .1, so you have
.8
The next element in the sum is the second digit after the decimal place times .01, so you get<span>
.8+.06=.86

Answer:
Direct variation is the relationship between two variables, whereby if one variable increases, the other also increases and vice versa. If one variable increases if the other decreases, it is called inverse variation.
