Answer:
a. -2
b. s = 2 and y = -5
c. (2.5, -9)
d. -7x - 2
Step-by-step explanation:
a. In the image, I have used rise over run, which is -8/4 or -2.
b. slope formula is mx + b = y, where m is slope and b is the y-intercept. In the equation 2x - 5y = -10, 2 is the slope and -5 is the y-intercept.
c. Plug in all given numbers into an equation and the ones you do not have will be in the points you need it to be. Once you graph the equation you will receive (2.5, -9).
d. y = mx + b
5 = (-7)(-1) + b
5 = 7 + b
-2 = b
y = -7x - 2
First simpliify
(3r^2+4)(2r-1)=
(3r^2+4)(2r)+(3r^2+4)(-1)=
(6r^3+8r)+(-3r^2-4)=
6r^3+8r-3r^2-4=
put back
6r^3-3r^2+8r-4-8r^3+6r^2=
-2r^3+3r^2+8r-4
Answer:
Answer: $3.5 per pound
Step-by-step explanation:
Solution: Convert 1 and 1/2 into a decimal which is 1.5 Then divide 5.25 by 1.5 to see how much it is per pound. $3.5 per pound is the answer!
