Which equation has the correct sign on the product?

Answer:

A

Step-by-step explanation:

help pls ! will give brainlest lol

Answers

Answer:

y=3/4x

Step-by-step explanation:

From the origin (0,0) count the rise to the next point (3) and then the run (4) leaving you with 3/4 as your slope.

well, we see that it is a linear function.

so, we should make an equation that follows:


y = mx + b


b = y intercept, which is 0 because it connects at the origin.


m is the slope, which is rise/run.

we find a point at ( 0.7 , 0.5 ).

the rise is 0.5, and the run is 0.7, so we do

0.5/0.7

and we get 0.714285714285714, which we can round to 0.7143 for the m.

we have everything we need.


so,


y=0.7143x


(the b is 0, so we don’t have anything else to add).

how much water should be added to 5 gallons of 50% acid solution to get a 20% solution?

Answers

Answer:

7.5 gallons

Step-by-step explanation:

2.5/5+x=0.2

This question is based on the concept of solving an  equation. Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

Given:

5 gallons of 50% acid solution to get a 20% solution.

According to question,

Let  it be x gallons of water should be added to 5 gallons of 50% acid solution to get a 20% solution.

Now, forming the equation, we get,

 0.50 ( 5 )  =  0.20  ( x + 5 )

Simplifying the equation.

We get,

2.5 = 0.2x + 1

1.5 = 0.2 x

x = 7.5

Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

How do you decide where to shade an inequality whose boundary dose not go through the origin?
A. For <, shade above the boundary
B. If (0,0) is a solution, shade where (0,0) is
C. For >,shade below the boundary
D.If (0,0) is a solution, shade the boundary.

Answers

Answer:

I’m pretty sure that it is D because it says boundary and not just where it is at.

Step-by-step explanation:

If you have an equation for your graph you would substitute the y AND x with 0, you the solve the solution and if the solution is true then the space where (0,0) is located becomes the shaded area because that resembles the area in which everything is a positive solution with the equation. If it is false then the opposite area is then shaded because (0,0) doesn’t work with the problem.
