Answer:
Stretch
Step-by-step explanation:
- Translation: A translation moves a shape up, down or from side to side but it does not change its size.
- Reflection: A reflection is a transformation which all the points of an object reflect or flip on a line called the axis of reflection or line of reflection. This transformation does not change its size.
- Rotation: A rotation is a transformation that turns a figure about a fixed point called the center of rotation. This transformation does not change figure's size.
- Stretch: A stretch is a transfoormation which stretch the figure (by multiplying by C>1). This transformation changes the size of the figure.
- Isometry: An isometry is a type of transformation that preserves the length of a figure's sides.
Thus, a stretch is not an isometry
Answer:
C. –2x – 10 = –2(x + 5)
Step-by-step explanation:
Clearer choices:
2x + 10 = –2(x – 5)
–2(x + 5) = 2x – 10
–2x – 10 = –2(x + 5)
–2(x – 5) = –2x – 10
All choices have either:
–2(x – 5) for A and D
or –2(x + 5) for B and C
Simplify these expressions by <u>expanding</u> with the distributive property. Multiply the outside term "–2" with each term inside the brackets.
–2(x – 5)
= (–2*x) – (–2*5) Multiply each term by the coefficient
= –2x – (–10) Simplify the double negative to a positive
= –2x + 10 Expanded expression
This is not the same answer in A and D. They are not correct.
–2(x + 5)
= (–2*x) + (–2*5) Multiply each term by the coefficient
= –2x + (–10) Adding a negative is the same as subtraction
= –2x – 10 Expanded expression
This is the same answer for <u>option C</u>.
Therefore "C" is the answer.
Answer: Write a quadratic function in vertex form whose graph has the vertex (1,2) and passes through the point (3,10). (what does F(x)=?) Algebra -> Quadratic Equations and Parabolas -> SOLUTION: Write a quadratic function in vertex form whose graph has the vertex (1,2) and passes through the point (3,10).
Step-by-step explanation:
Assuming that is a complementary angle meaning that the angle will add up to 90' your answer should be:
