Y=mx+b
m=slope=rise/run
if slope>0, then it increases
if slope<0, then decreases because it is going down
y=7-2x
y=-2x+7
-2<0
decreasing
because the y values decrease from left to right
the x values always increase if you go from left to right
B is the answer
∑ 4 * 5^(i-1) = 4 + 20 + 100 + 500 = 624
∑ 3 * 4^(i-1) = 3 + 12 + 48 + 192 + 768 = 1,023
∑ 5* 6^(i-1) = 5 + 30 = 35
∑ 5^(i-1) = 1 + 5 + 25 + 125 = 156
Answer:
∑ (i=1, 2) 5 * 6^(i-1) < ∑ (i=1, 4) 5^(i-1) < ∑ (i=1, 4) 4 * 5^(i-1) <
< ∑ (i=1, 5) 3 * 4^(i-1)
Its six idk really ask your teacher for more help
X(30;0)
y(0;50)
substitue 0 for y and solve for x
substitute 0 in for x and solve for y
You cant because there are 2 different variables
hope this helps, have a great day
