Answer:

x = 12

Step-by-step explanation:

Comparing corresponding sides of the 2 similar Δ 's inside the larger, then

$\frac{x}{6}$ = $\frac{6}{3}$ ( cross- multiply )

3x = 36 ( divide both sides by 3 )

x = 12

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:

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

Someone please help me with this!!!

Alexxx [7]

34.I
for this problem you just multiply the 20 by 2=40
and then you add 40+3=43
which will equal
$\frac{43}{20}$

35.G
if you divide
$58 \div 25 = 2.32$
so G
$\frac{58}{25}$

36. C
$\frac{5}{5} = 1$
so if you subtract
$\frac{6}{5} - \frac{5}{5}$
will equal

$\frac{1}{5}$
$1 \frac{1}{5}$
