A student say that the x-intercept of the graph x + 2y=5 is the point (0,5). Why is the student incorrect?
harina [27]

Answer:

the x-intercept is found when 0 is put into the equation for y.  

Because the x-intercept is found when the function passes through the x-axis.

x+2y=5

x=5

So x=5, y=0, the point would be (5,0).

Marley was asked to solve x2 - 4x + 9 = 0 using the Quadratic Formula. She found the discriminant first and decided she did not
saveliy_v [14]

We have been given Marley was asked to solve x^2-4x+9 = 0 using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.

We are asked to determine whether Marley is correct or not.

We know when an equation is in form ax^2+bx+c=0, we can use discriminant to check for the real solutions of equation.

D=b^2-4(a)(c)

If D>0, then the equation will have two real solutions.

If D=0, then the equation will have one real solution.

If D, then the equation will have no real solutions.

Let us find discriminant.

a=1,b=-4\text { and }c=9

D=(-4)^2-4(1)(9)

D=16-36

D=-20

Since -20, therefore, the equation will have no real solutions, so Marley is correct.

Find the rule and the graph of the function whose graph can be obtained by performing the translation 3 units left and 2 units d
ahrayia [7]

Answer: Option b.

Step-by-step explanation:

 1. You have the following parent function given in the problem above:

f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)

2. If you take the parent function and make y=f(x+3), then you have:

y=f(x+3)=(x+3)^{3} (The function is shifted 3 units left on the x-axis).

3. Then you if you make y=f(x+3)-2, as following, you obtain:

y=f(x+3)-2=(x+3)^{3}-2  (The function is shifted 2 units down on the y-axis).

4. Therefore, that is how you obtain the final function.

The answer is the graph shown in the option b.
