I think it’s -0.75. The x coordinate represents the term number so y would show the pattern which is -3.75, -4.5, -5.25, -6, -6.75, -7.5, -8.25, -9. To get to the next number, each term is being decreased by 0.75. Hope this helps :)

Answer:

The answer is 211.96

Step-by-step explanation:

First I did the semicircle, the radius is 7 so 7 x 2 = 14 and then I did

14 x 3.14 = 43.96

Then I did 12 x 14 = 168

Finally 168 + 43.96 = 211.96

Hope this helps

Hey there!

Use this formula:

$a^{-b} =\frac{1}{a^{b} }$

Remember this formula.

Now, let's solve the given problem.

$5^{-9} =\frac{1}{5^{9} }$

Hope this helps you!

T - 6.2 < 4 help me please

enyata [817]

Answer:

t < 10.2

Step-by-step explanation:

Step 1: Add 6.2 to both sides.

$t - 6.2 + 6.2 < 4 + 6.2$
$t < 10.2$

Therefore, the answer is t < 10.2.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Write the equation of the line in fully simplified slope-intercept form.

Lina20 [59]

Answer:

$y=-6x+2$

Step-by-step explanation:

Hi there!

Slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x=0)

1) Determine the slope (m)

$m=\displaystyle \frac{y_2-y_1}{x_2-x_1}$ where two points that fall on the line are $(x_1,y_1)$ and $(x_2,y_2)$

Given the graph, we determine which points we could use. For example, we could use the two points $(0,2)$ and $(1,-4)$ :

$m=\displaystyle \frac{-4-2}{1-0}\\\\m=\displaystyle \frac{-6}{1}\\\\m=-6$

Therefore, the slope of the line is -6. Plug this into $y=mx+b$ :

$y=-6x+b$

2) Determine the y-intercept (b)

Recall that the y-intercept occurs when x=0. Given the point (0,2), we know that the y-intercept is 2. Plug this into $y=-6x+b$ :

$y=-6x+2$

I hope this helps!
