The picture below shows Annie and her younger brother Tommy’s money.
lawyer [7]

Step-by-step explanation:

Annie: 4 dollars = $4 11 dimes = 11 x 0.10 = $1.1 ( since 1 dime = 0.10 dollars)

4 pennies =4 x 0.01= $0.04 ( since 1 penny = 0.01 dollars)

Tommy 3 dimes = 3 x 0.10 = $0.3 3 pennies = 3x 0.01 = $0.03

Adding the values: 4 +1.1+0.04+0.3+0.03 = $5.47

line y = 2x+1 is transformed by a dialation with a scale factor of two and centered at (0,-4). what is the equation of the image
Gekata [30.6K]

Answer: y = 2x + 6

Step-by-step explanation:

Here the equation of line,

y = 2x + 1

y-intercept of the line is, (0, 1)

And, the slope of the line is 2.

Since, If a point (x,y) is dilated by a scale factor k about a point (a,b),

Then transformed point are get by,

(x,y)\rightarrow (k(x-a)+a, k(y-b)+b)

Thus, The transformed point of point (0,1) when dilation is occur by the scale factor 2 about the point (0,-4),

(0,-4)\rightarrow (2(0-0)+0, 2(1+4)-4)

(0,-4)\rightarrow (0, 6)

Thus, the point of the new line is (0,6)

And, the slope of the new line is 2 ( because in the dilation, the slope of the line does not change)

Thus, the equation of new line,

(y - 6) = 2 (x - 0)

y - 6 = 2x

y = 2x + 6

Write two different equations to describe each situation. a) You buy 3 identical shirts and 2 identical pairs of socks and spend
Ronch [10]

Answer:

3x + 2y = 38,  3a + 2b = 38

Step-by-step explanation:

An equation may be defined as a statement that shows two mathematical expressions to be equal. It is to equate one thing to another thing.

In the context, two different equations for the situations are :

i). Let the shirt be represented by x

   And the socks be represented by y

Therefore, according to the question,

   3x + 2y = 38

ii). Let the shirt be represented by a

   And the socks be represented by b

Therefore, according to the question,

   3a + 2b = 38
