Answer:

y = ( x-4)(x+7)

Step-by-step explanation:

When we know the zeros of the equation, we can write the equation in the form

y= a(x-z1) (x-z2)   where a is a constant and z1 and z2 are the zeros (solutions)

y = a( x-4)(x--7)

y =a( x-4)(x+7)

Since its says write an equation, we can pick a and I will let a=1

y = ( x-4)(x+7)

What strategies do you use when multiplying decimals? Share your thinking using 2-3 sentences. This is an open-ended question so
Anit [1.1K]
I’m not sure if this is actually a strategy but can I get brainliest please. If I’m not allowed to use a calculator then I would covert the decimals to fractions. I would covert them to the simplest fractions before multiplying so that the answer is as closest to its simplest form as possible.

sveticcg [70]
Solutions 

Associative Property is a rule that refers to grouping. The rule is "<span>a + (b + c) = (a + b) + c</span><span>". 
</span>
The correct answers are (A) and (D) 

(A) = <span> (11 + 2.2) + (–5) = 11 + [2.2 + (–5)] 

(D) = </span><span>–7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)</span>

In a direct variation equation, f(x)=6 when x = 4. What is the direct variation equation?
jeyben [28]

Answer:

f(x) = \dfrac{3}{2}x

Step-by-step explanation:

The general direct variation equation is

y = kx

Plug in x = 4 and y = 6 and solve for k.

6 = k * 4

4k = 6

k = 6/4 = 3/2

f(x) = \dfrac{3}{2}x
