The first step in solving 7/8 = 3x - 5/11 is to subtract 5/11 from both sides of the equation.

False because -5/11 should be add on both sides

A spinner is divided into 8 equal sections. lara spins the spinner 120 times. it lands on purple 30 times. how many more times d

kvv77 [185]

She should not spin the spinner any more times, the relative probability is already more than the theoretical probability.

If there is only 1 purple section out of 8, that gives purple a 12.5% chance of being spun.

However, Lara got purple 30 out of 120 times. That is 25%. She is already over.

How many of the sections were purple?

Answer:

Step-by-step explanation:

y=3x+6

slope is 3, so y=3x+[unknown].

We insert the point (4,7) into the equation.

7=3*4+[unknown]

7=12+[-5]

so the answer is

y=3x-5

Find the slope of the line that passes through (4,2) and (9,1)?

pshichka [43]

Answer:

The slope of the line is $\displaystyle -\frac{1}{5}$ .

Step-by-step explanation:

We are given two coordinate points:

$(4, 2)$
$(9, 1)$

We are asked to find the slope of the line.

We can use the rise-over-run formula to solve for the slope of the line.

$\displaystyle \text{slope} = \frac{\text{rise}}{\text{run}}\\\\\text{slope} = \frac{y_2-y_1}{x_2-x_1}$

However, we firstly need to name our coordinate points.

In math, we can label our coordinates using the following label system:

$(x_1, y_1), (x_2, y_2)$

Therefore, we can also label our coordinates as such:

$x_1 = 4$
$y_1 = 2$
$x_2 = 9$
$y_2 = 1$

Now, we can supply these values into the formula and solve for our slope, or a better known variable, <em>m</em>.

$\displaystyle m = \frac{1 - 2}{9 - 4}\\\\m = \frac{-1}{5}\\\\m = -\frac{1}{5}$

Therefore, our slope is $\displaystyle -\frac{1}{5}$ .
