Find the X Intercepts y=x^2-3x+6 PLEASE HELP ME

1 answer:

3 0

The x intrercepts is where the function crosses the x axis; In other words, it is where the output of the function is 0.

In a quadratic, you can start by factoring, if it’s unable to be factored then use the quadratic formula. Also, it is good to use the discriminate.

D= Discrimminate

D>0 2 real solutions

D=0 1 real solution

D<0 2 imaginary solutions.

The discrimminate is the equation/expression under the radical of the quadratic formula. With this formula, it’s not factorable. Using the discriminate it is also seen, as you’ll get a negative in the square root. This is imagenary because you cannot take the root of a negative value, which is why “i” is used to represent the square root of negative one.

A system of equations has definitely many solutions. If 2y-4x=6 is one of the equations, which could be the other equation?

NISA [10]

The given equation is ⇒⇒⇒ 2y - 4x = 6

∴ 2y = 4x + 6 ⇒ divide all the equation over 2

∴ y = 2x + 3 and it can be written as ⇒⇒⇒ y - 2x = 3

The last equation represents a straight line with a slope = 2 and y-intercept = 3

To construct a system of equations with definitely many solutions and the equation ( 2y-4x=6 ) is one of the equations, the other equation must have the same slope and the same y-intercept.

so, the general solution of the other equation is ⇒ a ( y - 2x ) = 3a

Where a is constant and belongs to R ( All real numbers )

The system of equations which has definitely many solutions is consisting of Coincident lines.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -x + 1

2x + 3y = 6

Step 2: Solve for x

Substitution

Substitute in y: 2x + 3(-x + 1) = 6
Distribute 3: 2x - 3x + 3 = 6
Combine like terms: -x + 3 = 6
Isolate x terms: -x = 3
Isolate x: x = -3

Step 3: Solve for y

Define equation: y = -x + 1
Substitute in x: y = -(-3) + 1
Simplify: y = 3 + 1
Add: y = 4

)The histogram shows the number of gold medals won by different numbers of students at an art competition. Which of the followin

Mnenie [13.5K]

Answer:

Eight students won 6, 7, or 8 gold medals.

Step-by-step explanation:

We see that the third bin is labelled 6 - 8. Since this is on the horizontal, or x, axis, this means that the students in this "bin" have won 6 - 8 medals, which is the same as saying winning 6, 7, or 8 medals.

Because this "bin" goes to 8, that means that there are 8 students who earned this many medals.

Thus, the answer is D.

Hope this helps!
