Hope this helps!
Answer:
2
Step-by-step explanation:
y=2
Step-by-step explanation:
Make an equation of straight line by using the formula :y= mx+c
put the x-value of point (2,4) which is 2 and the gradient,m which is 2 into the straight line equation:
y=2x +c
So you need to find the y-intercept to complete the equation, therefore:
when y=0,
0=2(2)+c
c=-4
next the question ask to find the y-coordinate when x =3, therefore you just need to replace x in the equation with 3:
y=2(3)-4
y=4
Answer:

The quadratic equation has one real root with a multiplicity of 2.
Step-by-step explanation:
Given a quadratic equation:

You can find the Discriminant with this formula:

<em> </em>In this case you have the following quadratic equation:

Where:

Therefore, when you substitute these values into the formula, you get that the discriminant is this:
Since
, the quadratic equation has one real root with a multiplicity of 2 .
