Answer:
WHAT IS IT
Step-by-step explanation:
Answer:
23.39% off.
Step-by-step explanation:
Difference in price and your money
= 43.65 - 33.44 = $10.21.
So percentage off so you can buy is
(10.21 / 43.65) * 100
= 0.2339 * 100
= 23.39%.
Answer:
P(x) = -1.1x +49
Step-by-step explanation:
You are given the percentage in 2000 (for x=0) as 49, and told that its rate of change is -1.1 percent per year. So, with a slope of -1.1 and an intercept of 49, the slope-intercept form of the linear equation becomes ...
P(x) = -1.1x +49
_____
The slope-intercept form for slope m and y-intercept b is ...
y = mx + b
X is equal 25 degrees. Line ac goes though the parallel lines. So bcd is x. Cdb is 180-50 equals 130. All angles add to 180. 180-130 equals 2X. So x equals 25.
All you have to do it plug in the coordinations into the equation to find which is true. now let’s check it.
x - y = -4. (-5, -1)
-5 - (-1) = -4
-4 = -4 so this is correct.
x - y = -4. (3, 7)
3 - 7 = -4
-4 = -4. so this is correct
x - y = -4 (-3, 3)
-3 - 3 = -4
-6 = -4. so this is incorrect.
x - y = -4 (0, 3)
0 - 3 = -4
-3 = -4 so this is incorrect
x - y = -4 (-2, 6)
-2 - 6 = -4
-8 = -4. so this is incorrect
so your answers would be a & b.
