In this question we have a graph given and the curve represents parabola or quadratic equation and we have to find the zeroes, that is, we need to find the value of x where the curve crosses the x axis . And from the given graph , we can say that the curve crosses the y axis at y=-8 . and the x axis at x=-4 and x =2. So the zeroes of the given graph is x=-4,2 and the y intercept is -8 .

Answer:

Equivalent. 0.4(k+3)=0.4k+1.2

Step-by-step explanation:

x means multiplication. k is the variable.

Hi.

So, you have to distribute the 0.4 into the parenthesis to get rid of them. So, you do 0.4xk, which is just 0.4k, and 0.4x3, which is 1.2. So, you have 0.4k+1.2, which means it is Equivalent.

Reason-

0 can not be possible because if 0 is the first digit then , it will become the 3-digit password , not 4-digit

Your friend says that the solutions to the inequality 5x - 14x < - 18 are x ≤2. Solve the inequality correctly. What error di

katrin2010 [14]

<h3>Answer: x > 2</h3>

Work Shown:

5x - 14x < - 18

-9x < - 18

x > -18/(-9)

x > 2

The inequality sign flips when dividing both sides by a negative number.

Here's another approach you could take.

5x - 14x < - 18

-9x < -18

0 < -18+9x

18 < 9x

9x > 18

x > 18/9

x > 2

It's a slightly longer pathway, but it avoids a sign flip when you divide both sides by the positive number 9.

The sign flip happens two steps earlier when going from 18 < 9x to 9x > 18. In other words, A < B is the same as B > A.
