Answer 2
Answer:

3 + - 5 is basically 3 -5 because when a negative meets a positive the signs turn into a negative.

3 -5 is 5 less than three which is -2.

. Maria spent 1\9of the money her grandparents gave her on an adventure book. She also spent 1/3 of the money on a bag of candy. What fraction of the payment has Maria spent?

Answers

Answer:

(4)/(9)

Step-by-step explanation:

The fraction of the money that Maria spent on an adventure book = (1)/(9)

The fraction of the money that Maria spent on a bag of candy = (1)/(3)

Now we have to find the total fraction of the money that Maria spent.

For that we have to add those 2 fractions together.

Let us solve now.

( 1)/(9) +(1)/(3)

( 1)/(9) +(1*3)/(3*3)

(1)/(9) +(3)/(9)

(4)/(9)

There fore, the fraction of the payment has Maria spent is (4)/(9)

Hope this helps you :-)
If you add 1/9 and 1/3, it becomes 1/9+3/9, which equals 4/9. thus, 4/9 of the money has been spent. hope it helps!!

The endpoints of AB are A(9,4) and B(5,-4). The endpoints of its image after a dilation ar A(6,3) and B(3,-3). a. explain how to find te scale factor. b. locate the center of dilation. show your work

Answers

Look at the picture for the answer.

Final answer:

The scale factor of the dilation is calculated by dividing the length of the line after dilation by the length of the initial line. The length of a line is calculated using the distance formula. The center of dilation is the point from which the shape scales, but we can't determine its location without more information.

Explanation:

To find the scale factor of a dilation in a two-dimensional plane, we divide the length of the line after dilation by the length of the initial line. The length of a line can be calculated using the distance formula which is √[(x₂ - x₁)² + (y₂ - y₁)²].

For AB, the distance will be √[(5 - 9)² + (-4 - 4)²] = √[(-4)² + (-8)²] which equals √80. For A'B', the distance will be √(3 - 6)² + (-3 - 3)² = √[(-3)² + (-6)²] which equals √45. The scale factor (k) of the dilation is the ratio of these distances, so k = √45 / √80 which simplifies to √(9/16) or 3/4.

Unfortunately, without more information, such as a fixed point in the original shape, we can't determine the exact location of the center of dilation. But, conceptually, it's the point that the shape is scaling towards or away from during the dilation.

Answers

Solve:

[x+9] - there is nothing to simplify

======================================

Evaluate:

5(7-9)-2

= 35 -45-2

= -10-2

= -12

or

5(7-9)-2

= 35 -45-2

= 35-47

= -12
------------------------------------------
So, -12 is the answer.

What is an equation of the line that is perpendicular to y + 1 = -3(x - 5) and passes through the point (4, -6)?

Answers

Answer:

Option A.

Step-by-step explanation:

y + 1 = -3x + 15

y = -3x + 14

A line perpendicular would have a slope of 1/3.

y = 1/3x + c

-6 = 1/3 * 4 + c

4/3 + c = -6

c = -18/3 - 4/3

c = -22/3

So, we have y = 1/3x - 22/3.

y + 6 = 1/3(x - 4)

y + 6 = 1/3x - 4/3

y = 1/3x - 4/3 - 18/3

y = 1/3x - 22/3

So, the correct answer is Option A.

Hope this helps!
