Answers
Answer:The answer is (x,y)->(+4,y-5)
Step-by-step explanation:
since -4 to 0 is + 4 and 2 to -3 is -5
The correct mapping is (x, y) ⇒ (x + 4, y - 5)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).
Since the vertex Y(-4, 2) was translated to Y'(0, -3), hence the triangle was translated 4 units to the right (-4 + 4 = 0) and 5 units down (2 - 5 = -3). This can be represented by the mapping:
(x, y) ⇒ (x + 4, y - 5)
Therefore to find x and z coordinates, use the mapping:
(x, y) ⇒ (x + 4, y - 5)

At noon the temperature was -10° F. Over the next 4 hours the temperature went up 12°. Then every hour until 10 pm the temperature dropped 2°. What was the temperature at 10 pm?
Answers
Answer:
-10 degrees
Step-by-step explanation:
at noon the temp was -10. -10 + 12 = 2 and that is at 4 o'clock 2- 6 hours ( time until 10 pm) x 2. 2 - 12 = -10.
Answer: 0º F.
Step-by-step explanation:
Noon = 12 pm
At Noon it was -10º F, over the next 4 hours it went up to 12º F.
Noon + 4 hours = 4 pm
The temperature dropped 2º F every hour until 10 pm which means for 6 hours the temperature dropped.
6x2º F = 12º F which means the temperature dropped by 12º F.
12º F - 12º F = 0º F

C. Slope of Function A = 2 x Slope of Function B
Step-by-step explanation:
The slope of function A is the x-coefficient: 6.
The slope of function B is ...
... slope = (change in y)/(change in x) = (-2-4)/(-1-1) = -6/-2 = 3

Martina opens a savings account with an initial deposit and makes no other deposits or withdrawals. She earns interest on her initial deposit. The total amount of money in her savings account at the end of each year is represented by the sequence shown.

B. f(n + 1) = 5f(n)
C. f(n + 1) = 1.05f(n)
D. f(n + 1) = 0.05f(n)
Answers
1.05 should be it
Step-by-step explanation:
In a recursive formula, each term of the sequence is found by using the previous term. In this case, the sequence is geometric because we are multiplying each term by the same constant, called a common ratio.
To find this common ratio, we find the percent of change between terms. We do this by using the formula
% change = (amount of change)/(original amount)
The amount of change between the first two terms is 105-100 = 5. This makes the percent change
5/100 = 0.05
The amount of change between the second two terms is 110.25-105 = 5.25. This makes the percent change
5.25/105 = 0.05
However, the common ratio in the sequence is not 0.05. This is because multiplying by this decimal would make the terms decrease instead of increasing. In this case, we are taking 100% of the number and adding an extra 5% (0.05 = 5%); this makes our common ratio 105% = 1.05.
This gives us the recursive formula

Lines x and y are parallel. Write an equation that represents the relationship between b and e. Explain how you know this equation is always true. Your explanation should use AT LEAST TWO of the following terms: vertical angles, corresponding angles, congruent, supplementary.
please help
Answers
Answer:
m∠b + m∠e = 180°
Step-by-step explanation:
Lines x and y are the parallel lines and a transversal line is intersecting these lines.
∠b ≅ ∠h [Vertical angles]
∠h ≅ ∠f [Corresponding angles]
Therefore, ∠b ≅ ∠f [Congruent angles]
m∠f + m∠e = 180° [Supplementary angles]
m∠b + m∠e = 180° [Since, ∠b ≅ ∠f]
Therefore, equation representing the relation between ∠b and ∠e is,
m∠b + m∠e = 180°
The required equation that represents the relationship between b and e is m<b + m<e = 180
From the given diagram, we can see that the line x and y are cut by a transversal. This shows that the following statements are true;
m<b and m<g are supplementary i.e m<b + m<g = 180
Also m<b and m<f are equal (alternate interior angle)
m<b = m<d (vertically opposite angle)
Also, since m<d and m<e are supplementary angles (angle on a straight line), then m<b and m<e are also supplementary
Hence the required equation that represents the relationship between b and e is m<b + m<e = 180
