Given a dilation where k=2, would the image be an enlargement or a reduction?

For this case we have the following possible cases:

Case 1:
If the scale factor meets 0 <k <1 then the original figure shows a reduction.

Case 1:
If the scale factor complies with k> 1 then, the original figure presents an expansion.

In this case, the scale factor is:
k = 2 (k> 1)
Therefore, the figure presents an expansion.

Answer:
b) Enlargement

Solve to find X. 1/5(x - 2) = 1/10 (x + 6)

LenaWriter [7]

Answer:

x = 10

Step-by-step explanation:

First, distribute:

$\frac{1}{5} x - \frac{2}{5} =\frac{1}{10} x+\frac{6}{10}$

Next, subtract $\frac{1}{5}x$ from both sides:

$-\frac{2}{5} = \frac{1}{10} x -\frac{1}{5} x+\frac{6}{10}$

(multiply $\frac{1}{5}x$ by 2 to get common denominator, $\frac{2}{10} x$ )

$-\frac{2}{5} =-\frac{1}{10}x +\frac{6}{10}$

Next, subtract $\frac{6}{10}$ from both sides:

$-\frac{2}{5} -\frac{6}{10} =-\frac{1}{10} x$

(multiply $\frac{2}{5}$ by 2 to get common denominator, $\frac{4}{10}$ )

$-\frac{10}{10} =-\frac{1}{10} x$ ⇒ $-1=-\frac{1}{10} x$

Next, multiply both sides by 10:

$-10=-x$

FInally, divide both sides by -1:

x = 10

the sum of two numbers is 61. five times the smaller number is 23 more than the larger. find the numbers

Stella [2.4K]

Smaller Number = X
5x - 23 = Larger Number

X + (5x - 23) = 61
6x - 23 = 61
6x = 84
X = 14

Need help please and thank you

Norma-Jean [14]

Answer:

The length of XZ is 15 miles.

Step-by-step explanation:

Use Pythagorean Theorem to solve this problem

9² + 12² = C² Simplify the squares

81 + 144 = C² Add on the left side

225 = C² Take the square root of both sides

15 = C
