1 answer:

8 0

2(4x+5)>7x+20 perform indicated multiplication on left side

8x+10>7x+20 subtract 7x from both sides

x+10>20 subtract 10 from both sides

x>10

or in interval notation, x=(10, +oo)

On a coordinate plane, 2 right triangles are shown. The first triangle has points A (negative 1, 3), B (negative 1, 1), C (3, 1)

drek231 [11]

Answer:

B and E

Step-by-step explanation:

Given

ΔABC ⇒ A(- 1, 3), B(- 1, 1), C(3, 1)
ΔA'B'C' ⇒ A'(2, - 2), B'(2, - 4), C'(6, - 4)

Comparing the coordinates of the corresponding vertices, we see the difference:

x → x + 3, y → y - 5

It means the ΔABC has been translated 3 units right and 5 units down

Correct answer choices are B and E

Which construction is being shown in the diagram?

11Alexandr11 [23.1K]

Answer:

Correct answer is option D) Construct the bisector of an angle.

Step-by-step explanation:

Angle bisector of an angle is a line that divides the angle in two equal parts.

A Line BD is called the angle bisector of $\angle ABC$ if

$\angle ABD = \angle CBD$

Please refer to image attached.

As per the question image, if the line PW is joined it will be the angle bisector of $\angle QPR$ .

Steps of construction of angle bisector:

1. Draw the angle QPR.

2. Open compass and make an arc that will cut the two lines on points Q and R respectively as shown in question figure.

3. With the same compass opening, put the compass on Q and make an arc in the area between $\angle QPR$ .

4. Draw an arc keeping the compass on R to cut the previous arc on point W.

Line joining the points P and W is the angle bisector of $\angle QPR$ .

So, Correct answer is option D) Construct the bisector of an angle.

Claudia is on a motorcycle trip. She checked the odometer at the beginning of the trip, and it showed 16,789 miles. After 15 day

11Alexandr11 [23.1K]

22,189 - 16,789 = 5400....so she drove/rode 5400 miles in 15 days

5400/15 = 360 miles per day <==
