In the xy plane, what is the y intercept of the graph of the equation y=2 (x+3)(x+4)?

1 answer:

4 0

The y-intercept is the value of y when the graph intersects the y-axis. Graphs intersect the y-axis when x=0, so we just substitute in x=0 to get:

y=2(0+3)(0+4)

y=2(3)(4)

y=24

Therefore, 24 is our answer.

Hope I helped :)

Coordinates after 270 clockwise rotation is (-6,-2), (-3,-5) and (-8, -5).

<h3>What is graph?</h3>

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given coordinates are: (-2,6) , (-5, 3) and (-5, 8)

For 270° clockwise about the origin, we have the following rule:

(x, y)= (-y, x)

So,

coordinates (-2,6) change into (-6,-2)

coordinates (-5, 3) change into (-3,-5)

coordinates (-5, 8) change into (-8, -5).

When you subtract a number, you get the same results as when you add the opposite number. Why?

lapo4ka [179]

Answer:

Step-by-step explanation:

Well, the opposite of a number is the same number with the opposite sign. For example, the opposite of -1 is 1.

So, say we have an equation where we're subtracting a number, for example, 2-1, which obviously equals 1. Now, if we add the opposite of 1 to 2, we get the equation 2+(-1) which still equals 1.

I hope this helps!
