Perpendicular line has slope that multiplies to -1
paralel line has same slope
y=mx+b
slope=-7/4
perpendicular
4/7
(-7,-2)
-2=4/7(-7)+b
-2=-4+b
add 4 both sides
2=b
y=4/7x+2
paralel
y=-7/4x+b
-2=-7/4(-7)+b
-2=49/4+b
minus 49/4 from both sides (-2=-8/4)
-57/4=b
y=-7/4x-14.25
perpendicular
y=4/7x+2
paralel
y=-7/4x-14.25
Answer:
C. 114
Step-by-step explanation:
bikes have 2 wheels
skateboards have 4 wheels
incline skates have 8 wheels in total
7*2 = 14
9*4 = 36
8*8 = 64
if you add all of these up you get 114 wheels in total. 8*8 was from 24-7-9 = 8
Answer:
Maylin should purchase one unit of each socks & jogging shorts.
Step-by-step explanation:
In case of two goods, consumer is at equilibrium when marginal utility per dollar spent on last unit of the goods are equal, ie MU 1 / P1 = MU 2 / P2 (MU are the marginal utilities / marginal benefit of two goods, P are the price of two goods)
Given : MU1 (So) = 20, MU2 (JSh) = 30, P1 (So) = 10, P2 (JSh) = 15
So, equilibrium is at where MU1 (So) / P1 (So) = MU2 (JSh) / P2 (Jsh)
20/10 = 2, & 30/15 = 2. MU's per dollar are equal for both.
So Maylin is in equilibrium, she should purchase one unit of each socks & jogging shorts.
595 - 35t > 420
-35t > 420 - 595
-35t > -175
t < 5........so she can buy 4 tickets
