Answer:
The correct answer is D
Step-by-step explanation:
The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical ( is called the radicand because it is located in the radical) and the denominator in front of the radical, where it would be called the index.
You can change the denominator to 10 which will get you to 55/10 + 4/10. You can add these two together to get 59/10
Answer:
Here's how to do it.
Step-by-step explanation:
The two triangles must be similar, that is, corresponding angles must be equal, as in the diagram below.
1. Find a corresponding pair of sides
Assume that ∆ABC is the original and ∆DEF is its scaled image.
Then, AB and DE are corresponding sides, with lengths of 8 and 12 units , respectively.
2. Set up a ratio
Ratio = side length in image/side length in original = 12/8
3. Simplify the ratio
The simplified ratio is the scale factor (SF).
SF = 12/8 = 3/2 = 1.5
The scale factor is 1.5.
Answer:
y = 1/2x + 7
Step-by-step explanation:
y = mx+ b
y = 5
x = -4
5 = 1/2(-4) + b
5 = -2 + b
7 = b
