Answer:

x < −8

Step-by-step explanation:

Let's solve your inequality step-by-step.

−3(x+3)>15

Step 1: Simplify both sides of the inequality.

−3x−9>15

Step 2: Add 9 to both sides.

−3x−9+9>15+9
−3x>24

Step 3: Divide both sides by -3.

-3x 24

----- > -----

-3 -3

x < -8

Answer:

Use the information in the diagram to determine the height of the tree to the nearest foot.

algol13

Answer:

The correct option is A. The height of tree is 60 ft.

Step-by-step explanation:

From the given figure it is noticed that the building is creating a right angle triangle from a point and the tree divides the hypotenuse and base in two equal part.

According to midpoint theorem of triangle: In a triangle, if a line segment connecting the midpoints of two sides, then the line is parallel to third side. The length of line segment is half of the length of third side.

Using midpoint theorem of triangle, we can say that the length of tree is half of the building.

$Tree=\frac{1}{2}\times Building$

$Tree=\frac{1}{2}\times 120$

$Tree=60$

Therefore correct option is A. The height of tree is 60 ft.

(80 POINTS) What rule describes a dilation with a scale factor of ½ and the center of dilation at the origin?

lesya [120]

Answer:

Step-by-step explanation:

(x, y) -> (1/2x, 1/2y)

When you dilate a side, point, etc, you are multiplying the original dimension by the scale factor. That is represented in option C: the original x and y are multiplied by the scale factor, 1/2! Hope that helps! :)
