2(5c – 7) = 1

Distribute the 2 into the numbers within the parenthesis

10c-14=1

Add 14 to both sides

10c=15

Divide 10 on both sides

Final Answer: c= 1 1/2 or 1.5

<u><em>c=3/2 is the final answer. </em></u>First, you had to divide by two (2) from both sides of equation, and it gave us ⇒ \frac{2(5c-7)}{2}= \frac{1}{2}. And secondly, you had to simplify, and it gave us ⇒5c-7=\frac{1}{2}. Next, you had to add by seven (7) from both sides of equation, and it gave us ⇒5c-7+7=\frac{1}{2}+7. Therefore, you can also simplify, and it gave us ⇒5c=\frac{15}{2}. In fact, you divide by five (5) from both sides of equation, and it gave us ⇒\frac{5c}{5}= \frac{12}{2/5}. And finally, simplify it's should be the final answer is c=3/2 is the final answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

ABC is dilated by a scale factor of 3 with the origin as the center of dilation, resulting in the image A'B'C'. If the slope of
uysha [10]

Answer:

The slope of A'B' = -1.2 ⇒ answer A

Step-by-step explanation:

* Lets talk about dilation

- A dilation is a transformation that changes the size of a figure.  

- It can become larger or smaller, but the shape of the

 figure does not change.  

- The scale factor, measures how much larger or smaller  

  the image will be

- If the scale factor greater than 1, then the image will be larger

- If the scale factor between 0 and 1, then the image will be smaller

- If the center of the dilation is the origin then multiply each coordinate

 by the scale factor

* In the problem

∵ Δ ABC is dilated by a scale factor of 3 with the origin as the center

  of dilation

- Let point A is (a , b) and point B is (c , d)

∵ The slope of the line which passes through points (x1 , y1) and (x2 , y2)

  is m = (y2 - y1)/(x2 - x1)

∴ The slope of AB = (d - b)/(c - a) = -1.2

∵ Point A' is (3a , 3b) and point B' is (3c , 3d)

∴ The slope of A'B' = (3d - 3b)/(3c - 3a)

- Take 3 as a common factor from up and down

∴ The slope of A'B' = 3(d - b)/3(c - a) ⇒ cancel 3 up with 3 down

∴ The slope of A'B' = (d - b)/(c - a) = the slope of AB

∵ The slope of AB = -1.2

∴ The slope of A'B' = -1.2

* The slope of A'B' = -1.2
