Hello! Slope is rise/run. The formula for finding slope is y2 - y1 / x2 - x1, where you subtract the first x and y-coordinates from the second x and y-coordinates. We have the points (-2, -3) (first) and (4, 0) (second). Let's find what the numbers represent and then solve.
y2: 0
y1: -3
x2: 4
x1: -2
It becomes set up as 0 - (-3) / 4 - (-2). 0 - (-3) is 3. 4 - (-2) is 6. Keep in minid that when you subtract a negative number, you are actually adding. 3/6 is 1/2 in simplest form. There. The slope is 1/2.
Answer:
27.9 dollars
Step-by-step explanation:
2.70= 15 percent
2.70x2=5.4=30 percent
5.4+2.70=8.1=45 percent
8.1x2=16.2=95 percent
95 percent + 15 percent=18.9
18.9=105 percent
in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3
which = .9
18.9+9=27.9
100 percent is 27.9 dollars
4p+25=6p-18-12+9p Distribute
4p+25=15p-30 Combine like terms
25=11p-30 Subtract 30 from both sides
11p=55 Divide
p=5
It depends on the scale factor if you could attach an image that would help people to answer your questions in the future.
