Well through deduction you can immediately tell she had $1,000 dollars in her savings. Due to how it's like saying she paid $55 dollars which is 55% of her money, how much did she have in total?
However to properly solve the problem:
55% can be seen as 0.55 in decimal form. So... divide $550 by 0.55 and you'll get your answer.
550 / 0.55 = 1,000
Therefore she had 1,000 dollars before spending.
I hope that helps, have a great rest of your day! ^ ^

Answer:
x = 1 , -6
Step-by-step explanation:
given,
ln (x + 2) = ln (12) − ln (x + 3)
using identity of logarithm
ln (ab) = ln (a) + ln (b)
ln (a) - ln(b) = ln (a/b)
now
ln (x + 2) = ln (12) − ln (x + 3)
ln (x + 2) = ![ln (\dfrac{12}{x+3})](https://tex.z-dn.net/?f=ln%20%28%5Cdfrac%7B12%7D%7Bx%2B3%7D%29)
on comparing
![x + 2 = \dfrac{12}{x+3}](https://tex.z-dn.net/?f=x%20%2B%202%20%3D%20%5Cdfrac%7B12%7D%7Bx%2B3%7D)
(x+2)(x+3) = 12
x² + 5 x + 6 = 12
x² + 5 x - 6 = 0
x² + 6 x - x - 6 = 0
x(x + 6) -1 (x+ 6) = 0
(x - 1)(x + 6) = 0
x = 1 , -6
Hence, the value of x comes out to be x = 1 , -6
Answer:
7. y=x-2, 8. y=3/2x+4, 9. y=-3/4x+8, 10. y=2x-7, 11. y=-5x-3, 12. y=4x-5, 13. y=-3x-1, 14. y=-1/2x+1, 15. y=3/2x+4
Step-by-step explanation:
First you have to plug in the points into y2-y1/x2-x1. This would make it -2-0/0+1. Simplify this to get -2/1 which is -2. This makes the slope -2. Then plug in the slope into point intercept form y-y1=m(x-x1) where m is the slope. This time, I will use the point (0,-2). Therefore, the equation will be y+2=1(x-0) which is equal to y+2 =x-0 which is equal to y=x-2.
This is how you do all of the problems. For problem 13-15, you know that f(0)=-1 is (0,-1) and f(3)=-10 is (3,-10). Then you can solve the problems. I will not explain every single problem but will give you the answers.
