Answer:
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Step-by-step explanation:
0 = – 3x2 – 2x + 6
It can still be written as
– 3x2 – 2x + 6 =0
Quadratic formula=
-b+or-√b^2-4ac/2a
Where
a=-3
b=-2
c=6
x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Step-by-step explanation:
Given the expression that Tayler tried to evaluate as:
We will solve this equation using PEDMAS
Multiplication before addition and subtraction
On solving:
From the steps above, we can see that Tayler made an error in step 3 by taking the difference of 7 and 6 and arriving at 1 instead of summing up to get 13 as shown above.
Answer:
An expression y = 10+ 2x
Step-by-step explanation:
As per the statement: To play bingo,there is a $10 cover charge plus $2 per bingo card.
Let x represents the number of bingo card and y represents cost .
"$2 per bingo card" means 2x
"$10 cover charge plus $2 per bingo card" means 10 + 2x
then,
an expression to represents this statement;
y = 10 + 2x
