let length = x

width is 7 feet less than length

width = x-7

area = length *width

area = x(x-7)

170=x²-7x

x²-7x-170=0

x²-17x+10x-170=0

x(x-17)+10(x-17)=0

(x-17)(x+10)=0

x=17 or x=-10

since length cannot be negative so x=17

and width =x-7 =17-7=10

length =17 feet and width =10 feet

What is the sum of the reciprocal of 1/-13 and the reciprocal of -1/2
murzikaleks [220]

Answer:

-15

Step-by-step explanation:

1/-13

The reciprocal is

1/ 1/-13

Because of the law of indices,

We'll have 1 * -13

= -13.

-1/2

The reciprocal is

1 ÷ -1/2

Because of the law of indices,

We'll have 1 * -2

= -2

Therefore, the sum would be -13 + (-2) which would be equals to -15.

The transformed equation y = -(x - 2)^2 - 3 compared to the parent function involves  translating the parent function to the right by 2 units, reflecting the function across the y-axis and translating the function 3 units down

<h3>How to compare the function to its parent function?</h3>

The equation of the transformed function is given as:

y = -(x - 2)^2 - 3

While the equation of the parent function is given as

y = x^2

Start by translating the parent function to the right by 2 units.

This is represented as:

(x, y) = (x - 2, y)

So, we have:

y = (x - 2)^2

Next, reflect the above function across the y-axis

This is represented as:

(x, y) = (-x, y)

So, we have:

y = -(x - 2)^2

Lastly, translate the above function 3 units down

This is represented as:

(x, y) = (x, y - 3)

So, we have:

y = -(x - 2)^2 - 3

Hence, the transformed equation y = -(x - 2)^2 - 3 compared to the parent function involves  translating the parent function to the right by 2 units, reflecting the function across the y-axis and translating the function 3 units down
