HELP PLEASE!!!!

When trying to solve a system of equations graphically, our focus is on identifying the coordinates of any point through which the graphs go. Look at the above graph: you'll see that the red and the blue graphs intersect at (0,2), and so (0,2) is a "solution" of that system of equations.

Here, we're asked to answer a different kind of question: "Is (2,0) a solution to the given system of equations?" Let's paraphrase that question: "Do both graphs go through (2,0)?" The answer: emphatically not. Neither graph goes through (2,0). Thus, (2,0) is not a solution to this system of equations.

There are 5 tomatoes, 5 bell peppers, and 5 cucumbers in the refrigerator. If Bodhi gets to pick twice and keeps what was random
irga5000 [103]
Hello!

First of all there are fifteen total vegetables. First of all we have the probability that he will get a tomato.

\frac{5}{15} =  \frac{1}{3}

Now if he were to select a tomato there would only be fourteen vegetables left. Now our probability will be out of 14. Now we have the cucumber.

\frac{5}{14}

Now we multiply our two probabilities.

\frac{1}{3} (\frac{5}{14} = \frac{5}{42}

Therefore, Bodhi will have D) 5/42 chance of selecting a tomato and then a cucumber.

I hope this helps!

Gwendolyn is asked to solve the equation –4(x – 3) = 20. She shows the work below and states that the solution is x = –8. –4(x –
____ [38]

Answer:

x=-2

Step-by-step explanation:

Given: Equation is -4(x-3)=20

To find: flaw in Gwendolyn's work and the correct solution to the equation.

Solution:

In the given question,

the first step is -4(x-3)=20

The second step is -4x+12=20

(This step is obtained on multiplying -4 by x-3)

The third step is -4x=32

This step is wrong as on transposing 12 from left side of the equation in the second step to the right side, the following equation is obtained:

-4x=20-12\\-4x=8\\x=-2

So, the correct solution is x=-2
