The answer is b. (-2,2)

Since it is a dilation of 2, multiply each number by 2.

-1*2=-2
1*2=2

So after the dilation, it would be (-2,2)

Rose watches a circular ornament that has 6 equally spaced stones. identify x
Feliz [49]

Answer:

x = 60°

Step-by-step explanation:

It is given that the stones are equally spaced. As the circle is divided into 6 parts by 6 split points and there are 360∘ in the circle, each part equals 360∘/6 = 60∘. So,

mAB◠ = 60∘

mBC◠ = 3 (60∘)  = 180∘

If a tangent and a secant intersect in the exterior of a circle, then the measure of the angle formed is half the difference of the measures of its intercepted arcs.

x = 1/2 (mBC◠ − mAB◠)

Substitute the known values into the formula.

x = 1/2 (180∘ − 60∘)

= 1/2 (120∘)

= 60∘

Therefore, x = 60∘.

You are running a fuel economy study. One of the cars you find is blue. It can travel 30 1/2 miles on 1 1/4 of gasoline. Another
Furkat [3]

You are running a fuel economy study. One of the cars you find is blue. It can travel 30 and one half miles30 1 2 miles on 1 and one fourth gallons1 1 4 gallons of gasoline. Another car is red. It can travel 25 and three fifths miles25 3 5 miles on four fifths gallon 4 5 gallon of gasoline. What is the unit rate for miles per gallon for each​ car? Which car could travel the greater distance on 1 gallon1 gallon of​ gasoline?

 

Blue car: 30.5 / 1.25 =24.4 miles per gallon

Red car: 25.6/0.80   =32 miles per gallon

You can easily see that the Red car travel farther on 1 gallon of gasoline.

Y - 2 = -3/4 (x - 6)
y = -3/4 (x - 6) + 2
When, x = -2,
y = -3/4 (-2 - 6) + 2 = -3/4 (-8) + 2 = 6 + 2 = 8
One point is (-2, 8)
When, x = 2,
y = -3/4 (2 - 6) + 2 = -3/4 (-4) + 2 = 3 + 2 = 5
Another point is (2, 5)

A model rocket was launched from the ground and shot 150 feet straight up.It then fell back down to the ground and landed in the
Elena L [17]
The list of choices you included doesn't have any correct expressions on it.

-- If the rocket went straight up, and then dropped back at the same place
it was launched from, then it must have dropped straight down.

-- The route it followed on the way down was exactly the same as the
route it followed on the way up.

-- Since it reached a maximum height of 150-ft from the ground
and the route was straight, the length of the route was 150-ft.

-- (150-ft going up) plus (150-ft coming down)  =  300-ft traveled all together.
