Y=2x and y = x² - 3. To find the intersections of these 2 functions we proceed as follows:

2x= x²-3 → x² - 2x -3 =0

The zeros of this trinomial are x = 3 and x =-1

Now to find y-coordinates replace in any of the initial equation x by both values:
y = 2x . For x = 3 , y = 6
and for a = -1, y = -2

Use the distributive property to find an equivalent expression.

If you’re looking for equivalent expressions then there’s this:

5(2+3) = 5*5

5(2+3) = 10+15

If you’re looking for the answers, it’s 25. This is because 5*2=10 and 5*3=15. 10+15 is 25. Or you could add 3 and 2 (which is 5). Then 5*5= 25.

Hope this helped :)

–5(s – 30) = –10 please please help me

Gemiola [76]

Answer:

s=32

Step-by-step explanation:

$\frac{-5}{-5}(s -30) = \frac{-10}{-5}$

Divide both sides by -5

s-30=2

Add 30 to both sides

$s-30+30=2+30$

s=32

Y-2=4(x-1) use the point slope for each equation

melomori [17]

Slope = 4

Point = (1, 2)

<h2>Explanation:</h2>

Remember you need to post complete questions in order to get precise and good answers. However, I'll assume you need the point and slope of the following line:

$y-2=4(x-1)$
