Answer with explanation:
→The quadratic function is
y = 3 x² + 12 x + 10
→Vertex of the parabola=(-2,-2),in third Quadrant.
→Drawing the Parabola,which will open upwards ,that is along positive y axis.
→ Line, x= -2 , is the line of symmetry of Quadratic function.
As,the function is Quadratic, it has either two real root or two imaginary.
But, it has two real root, which are , x=-2.816,-1.184, because,
Discriminant >0.
D=12²-4×3×10
=144 -120
D=24
Answer:
$702.53
Step-by-step explanation:
Start with Jose's initial balance.
He wrote checks, so we have to subtract the total amount the checks were worth. Let's first add the three amounts.
Solve.
Subtract the total amount of the checks from Jose's initial balance.
Solve.
The amount above is now what is in Jose's checking account.
But, he also deposited money, meaning he put money in his checking account. Now, let's add the three amounts he deposited.
Solve.
The amount above is what Jose adds to his checking out.
Add the total value of the deposited money and his new balance.
Solve.
According to the information the complete comparison would be: 3 + 7 > 7 + 3
The comparison "3 + 7 > 7 + 3" is true. Both sides of the inequality are equal to 10, but the left side of the inequality is "3 + 7" and the right side is "7 + 3".
According to the above, we can conclude that since addition is commutative, the order of the numbers doesn't matter, and both sides are equal. Therefore, the comparison is true and complete.
So, we can conclude that the correct and complete comparison would be:

Answer:
81%
Step-by-step explanation:
1. We assume, that 200 equals 100% -because it's the output value of the task
2. We assume, that x is the value we are looking for.
3. If 100% equals 200,so we can write it down as 100%=200
4. We know, that x% equals 162 of the output value, so we can write it down as x% =162
5. Now we have two simple equations
1) 100%=200
2) x%=162
where the left sides of both of them have the same units, and both of the right sides have the same units, so we can do something like that:
100%/x%=200/162
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. the solution for 162 is what percent of 200
100%/x%=200/162
(100/x)*x=(200/162)*x -we multiply both sides of the equation by x
100=1.234567890123*x -we divide both sides of the equation by (1.234567890123) to get x
81%=x
x=81%
now we have:
hope this helps!
