Answer:14
Step-by-step explanation:
Well first because in this equation the first value is less than one, we should multiply the whole equation by 3, so
<span>x/3= x+1/4
x=3x+3/4
now we should switch the values
3x+3/4=x
now subtract x from both sides
2x+3/4=0
now subtract 3/4 from both sides
2x=-3/4
now divide both sides by 2
x=3/8
So that's your answer!

Answer:
1,887,436,800
Step-by-step explanation:
f(t) = a·b^t
f (t) = number of cases at year t
a = starting value = 1800 in 1983
b = growth factor = 2
t = years since 1983 = 2003 - 1983 = 20
f(t) = 1800·(2)^20 =
1,887,436,800

Answer:
y = 2
Step-by-step explanation:
Addition Method:
4x - 2y = 6
2x + y = 7
-2(2x + y) = -2(7)
4x - 2y = 6
-4x - 2y = -14
-4y = -8
y = 2
Substitution Method:
4x - 2y = 6
2x + y = 7
-2y = 6 - 4x
2y = 4x - 6
y = 2x - 3
2x + (2x - 3) = 7
4x - 3 = 7
4x = 10
x = 2.5
2(2.5) + y = 7
5 + y = 7
y = 2

Answer:
1. 2x + 3y =22
y=4
C. (5,4)
2. y=0
-5x - 2y = -15
B. (3,0)
Step-by-step explanation:
2x+(3)(4)=22
Step 1: Simplify both sides of the equation.
2x+12=22
Step 2: Subtract 12 from both sides.
2x+12−12=22−12
2x=10
Step 3: Divide both sides by 2.
2x/2 = 10/2
x=5
====================================================================
−5x−(2)(0)=−15
Step 1: Simplify both sides of the equation.
−5x−(2)(0)=−15
−5x+0=−15
(−5x)+(0)=−15(Combine Like Terms)
−5x=−15
−5x=−15
Step 2: Divide both sides by -5.
−5x/−5 = −15/−5
x=3
