<h3>Answer: Choice C)  (x-4, y)</h3>

Explanation:

We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.

The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.

Overall, the rule is (x,y) \to (x-4, y) which translates the point 4 units to the left.

Number 11 please , someone? Thank you .

In a triangle, the measure of an angle is in the same order of size as the length of the opposite side. The smallest angle is opposite the shortest side. The largest angle is opposite the longest side. The middle-sized angle is opposite the middle-sized side.

Also, in a triangle, the sum of the measures of the interior angles is 180.

We can now calculate the measures of the three angles by writing and solving an equation.

m<A + m<B + m<C = 180

9x - 7 + 7x - 9 + 28 - 2x = 180

Collect like terms on the left side.

9x + 7x - 2x - 7 - 9 + 28 = 180

14x + 12 = 180

Subtract 12 from both sides.

14x = 168

x = 12

Now that we know x, we can find the measure of each angle.

m<A = 9x - 7 = 9(12) - 7 = 108 - 7 = 101
m<B = 7x - 9 = 7(12) - 9 = 84 - 9 = 75
m<C = 28 - 2x = 28 - 2(12) = 28 - 24 = 4

(Quick check: Add the angles measures: 101 + 75 + 4 = 180. The sum is 180 as it should be.)

Now that we know the angle measures, the opposite sides are in the same order of size.

AB < AC < BC

The sides are, in increasing order of length:

AB, AC, BC

Martin won first place in the 100-meter dash with a time of 14 23/100 seconds.Samuel came in second place with a time of 15 7/10
ohaa [14]

Answer: The answer is 47th of 100 of a second.


Step-by-step explanation:  Given that in the 100-metre dash, Martin won first place by taking a time of

M_t=14\dfrac{23}{100}=\dfrac{1423}{100}~\textup{seconds}.

And, Samuel came second by taking time of

S_t=15\dfrac{7}{10}=\dfrac{157}{10}~\textup{seconds}.

The difference between the time of arrival of Martin and Samuel is given by

t=S_t-M_t=\dfrac{157}{100}-\dfrac{1423}{100}=\dfrac{47}{100}.

Thus, Martin beat Samuel by forty seven - hundredth of a second.
