Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.
Answer:
2 is the correct option.
Step-by-step explanation:
We have the equation
.
We will plot the graphs of the function
and
.
Then, the intersection points of both the graph will be the solution of the equation
.
From the graphs, we see that,
The intersection points of the graphs are (0,1) and (2.337,10.347).
The solution of the equation is the value of 'x' co-ordinate where they intersect.
So, we get, x = 2 is the correct option.
To do this, you’ll have to utilize the formula for volume.
Volume = length•width•height
V = 12•6•4
V = 12•24
V = 288 cm^3
** Remember that volume is always cubed.
Answer:
-6
Step-by-step explanation:
The equation is y = -7x - 6.
The initial value is found when x = 0.
y = -7(0) - 6
y = 0 - 6
y = -6
Answer:
violates the rules or bedmas
Step-by-step explanation:
When doing questions like these, bedmas comes into play. althought multiplication and division are the same in terms of priority, you should do the one that comes first when reading the equation/formula left to right.
this would mean you would do 2 ÷ 3 and the answer would be multiplied by 12.
