Lady bird [3.3K]3 years ago
5 0

Answer:

The domain is x ≥ -7

Step-by-step explanation:

The domain asks what values can x take

We know that the sqrt(x+7) must be ≥ 0

That means the smallest value it can be is zero

x+7 ≥ 0

x ≥ -7

The domain is x ≥ -7

Enter the slope-intercept equation for the image of line ℓ after a clockwise rotation of 90°. (Hint: To find the image of line ℓ
Free_Kalibri [48]

Answer:

y = -2x - 2

Step-by-step explanation:

From the graph attached,

If the line 'l' passes through two points A(0, -1) and B(4, 1).

Rule for the rotation of any point (x, y), 90° clockwise about the origin is,

(x, y) → (y, -x)

By this rule,

A(0, -1) → A'(-1, 0)

B(4, 1) → B'(1, -4)

Let the equation of the line A'B' is,

y - y' = m(x - x')

where m = slope of the line A'B'

And (x', y') is a point lying on the line.

Slope of the line passing through A' and B' will be,

m = \frac{y_2-y_1}{x_2-x_1}

m = \frac{0+4}{-1-1}

m = -2

Therefore, equation of the line passing through (-1, 0) and slope = -2,

y - 0 = (-2)(x + 1)

y = -2x - 2

So the equation of the line after rotation of lie 'l' by 90° clockwise will be,

y = -2x - 2

Jones has a 100-acre farm. he sells it to a developer who is going to build houses. the developer will use 10% of the land for s
Sholpan [36]
The first thing we must do is find the amount of land that will be used for the 120 lots.
 We must remember that 10% of the land will not be used for the lots.
 We have then:
 100 - (0.10) * (100) = 100 - 10 = 90 acres.

 Then, we must consider the following conversion of units:
 1 acre = 43560 ft ^ 2

 Applying the conversion we have:
 (90) * (43560) = 3920400 ft ^ 2

 Then, the amount of square feet for each lot is given by:
 3920400/120 = 32670 ft ^ 2

 Answer:
 
There will be 32670 square feet in each lot.
