Answer:
x=
3/2y
Step-by-step explanation:
3y=2x
Step 1: Flip the equation.
2x=3y
Step 2: Divide both sides by 2.
2x
2
=
3y
2
Answer:
(f•g)(-5) = -238
Step-by-step explanation:
We have that:
f(x) = -3x + 2
g(x) = 4x + 6
Find (f•g)(-5).
First we find (f.g)(x)
So
f(x)*g(x) = (-3x + 2)*(4x + 6) = -12x² -10x + 12
When x = -5
-12(-5)² - 10(-5) + 12 = -238
(f•g)(-5) = -238
Answer:
Kenyan French Roast coffee x=6
Sumatran coffee y=14
Step-by-step explanation:
x+y=20 blend coffee
8x+7y=7.3(20) selling price
x+y=20 ⇒ x=20-y
substitute in the equation:
8x+7y=7.3(20)
8(20-y)+7y=7.3(20) for 20 pound blend
160-8y+7y=146
-y=146-160
y=14 pond
x+y=20
x=20-14=6
check : 14*7+6(8)=146/7.3=20 pound

Answer:
n = 9
Step-by-step explanation:
20 + 18 + ... + 6 + 4
---------------------------
a = 20 ; d = -2 ; n = ?
--------
4 = 20 + (n-1)(-2)
-16 = (n-1)(-2)
---------
n-1 = 8
n = 9
-------
S(9) = (9/2)(20+4)
S(9) = 4.5*24
S(9) = 108
