Solution:

Given the expression:

$-5^2$

This expression is evaluated as

$\begin{gathered} -5\text{ multiplied in 2 places} \\ \Rightarrow-5\times-5 \\ =25 \end{gathered}$

Hence,

$-5^2$

is evaluated to be 25

Find an equation of the line passing through the point (4,3) with slope m=3

Marta_Voda [28]

Answer:

y=3x-9

Step-by-step explanation:

Enough information is given to write the line's equation in point slope form:

$y-y_1=m(x-x_1)\\'m' - slope\\(x_1,y_1) - coordinate$

The slope is three and the point is (4,3).

Replace the equation with the given information:

m = 3

x1 = 4

y1 = 3

$y-3=3(x-4)$

We can also make the equation into a slope intercept equation:

$y-3=3(x-4)\\\rightarrow y-3=3x-12\\\rightarrow y-3+3=3x-12+3\\\boxed {y=3x-9}$

So, the equation would be $y=3x-9$ .

Based on the scatterplot, which equation BEST represents the relationship between velocity and time?

lutik1710 [3]

The line of best-fit that represents the relationship between velocity and time is:

v = 2.19t + 6.7.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v) are given as follows:

(0, 6.1), (2.1, 12.2), (5.3, 17.4), (8.2, 26.4), (10, 28.1), (12.1, 32.8).

Hence, inserting these points into a calculator, the equation is given by:

v = 2.19t + 6.7.
