Answer:

y=-2x+7

Step-by-step explanation:

Slope is y(2)-y(1)/x(2)-x(1)

I chose (1,5)(0,7) as my two points and got -2 as my slope

Then, I got (0,7) as my y-intercept because it was in the table.

So, the equation is y=-2x+7

(hope this helps :P)

For the function y=-1+6cos(2pi/7(x-5)) what is the minimum value?

s344n2d4d5 [400]

Answer:

The minimum value of y is -7

Step-by-step explanation:

Given: $y=-1+6\cos(\dfrac{2\pi}{7}(x-5))$

We are given a cosine function.

We need to find minimum value of function.

$y=-1+6\cos(\dfrac{2\pi}{7}(x-5))$

Here y is depends on cosine function.

y is minimum when cosine is minimum because y is directly proportional to cosine function.

Minimum value of cos x is -1

Therefore, For minium value of y

$\cos(\dfrac{2\pi}{7}(x-5))=-1$

Minimum value of y

$y=-1+6(-1)$

$y=-7$

Hence, The minimum value of y is -7

HELP PLEASE In this polygon, all angles are right angles. What is the area of this polygon? Enter your answer in the box. ft² Po

Stels [109]

Answer:

258 ft²

Step-by-step explanation:

This shape is represented as a rectangle with dimensions of 18ft by 21 ft and a portion of it that has been cut out.

Let's find the area of the original rectangle:

18ft x 21ft
378 ft²

Now let's find the area of the part cut out:

12 ft x (18ft - 8ft)
12 ft x 10ft
120 ft²

Subtract the part cut out from the original rectangle:

378 ft² - 120ft²
258 ft²
