Ok firstly convert the first equation into the understandable form.
y = -2x +3

Next draw a dot on the y-ax at the height of +3 (3 is c in (y = ax + c) and c is always the intersection with the y-ax).

Next substitute y with 0,
0 = -2x + 3
<=> x = 3/2
Draw a dot on the x-ax at x=3/2 or 1.5.
Connect the two dots and you have the first function.

Now do the same thing for the second equation and read the coordinates from the intersection of the two equations.

That’s it!

Factor the numerator to get:

(-3z(z+5))/(z+5)  now you notice that (x+5) cancel out leaving:

Which expressions are equivalent to (2^2-9) (x + 3)?
mestny [16]

Answer:

(x^2-3^2)(x+3)

(x-3)(x+3)(x+3)

(x-3)(x+3)^2

Step-by-step explanation:

Given

(x^2-9)(x+3)

Required

Select 3 equivalent expressions

(x^2-9)(x+3)

Express 9 as 3^2

(x^2-3^2)(x+3) --- This is one equivalent expression

Take x^2 - 3^2 as difference of two squares

(x-3)(x+3)(x+3) -- This is another equivalent expression:

Solving further:

(x-3)(x+3)(x+3) becomes

(x-3)(x+3)^2   -- This is another equivalent expression:

Hence, the equivalent expressions are:

(x^2-3^2)(x+3)

(x-3)(x+3)(x+3)

(x-3)(x+3)^2

If sin ø = 1/3, what are the values of cos ø and tan ø?​
jekas [21]

Step-by-step explanation:

SinA=1/3=p/h

p=1,h=3,and b=?

Using Pythagoras Theorem,

b=√3^2-1^2

b=√9-1

b=√8=2√2

Now,

CosA=b/h=2√2/3

TanA=p/b=1/2√2

There is no phi in my keypad so I use A angle instead of phi.Adjust it.
