What’s the difference between evaluating an expression for a given value of a variable and solving an equation?

1 answer:

6 0

The difference is that evaluating an expression for a given value is an example of let’s say In a example, the variable x is equal to 6 since 6 + 6 = 12. So it means that they are giving you the input already. SOLVING an equation is working backwards, to undo everything that has been done to the input. So you have to do the equation in order to find your answer.

Which linear equation best represents the line of best fit for the scatterplot?

Lena [83]

Answer:

$y = -\frac{1}{3}x$

Step-by-step explanation:

The scatter plot trends downward from left-> right, meaning that it is negative. Next, use two points to solve for the value for the slope.

In this case, I will use (-3 , 1) & (0 , 0)

Use the following equation. m = slope:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Let:

$(x_1 , y_1) = (0 , 0)\\(x_2 , y_2) = (-3 , 1)$

Plug in the corresponding numbers to the corresponding variables:

$m = \frac{1 - 0}{-3 - 0} = \frac{1}{-3} = -\frac{1}{3}$

Your answer will be:

$y = -\frac{1}{3}x$

Diana worked on her science project for 6 1 3 hours. Gabe worked on his science project 1 3 4 times as long as Diana. Paula work

Vaselesa [24]

Are your numbers right? Diana worked on her project for 613 hours, Gabe worked on it for 134 times as long as Diana, and Paula worked on her science project 34 times as long as Diana? Assuming they are, It is false that Diana worked longer on her science project than Gabe worked on his. Tell me if I read the question wrong, I am happy to help.
