Answer:
a. 41.5
b, 26.5
Step-by-step explanation:
a.
2x + 6 = 180
2x = 172
x = 86
b.
2x+ 90 +26+11 = 180
2x+127 = 180
2x = 53
x = 26.5
Answer: B
Step-by-step explanation:
Answer:
$1.50
Step-by-step explanation:
Lehana earns ...
I = Prt = $100·0.025·3 = $7.50
in 3 years.
___
Marty earns ...
I = Prt = $100·0.020·3 = $6.00
in 3 years.
___
Lehana earns $7.50 -6.00 = $1.50 more after 3 years.
Negative reciprocal means
-1/4 times x=-1 solve for x
multiply both sides by -4/1
x=-4
so slope=-4
y=mx+b
m=slope, b=y intercpet
y=-4x+b
input 3 for x and -5 for y
-5=-4(3)+b
-5=-12+b
add 12 to both sides
7=b
the equation in slope intercept form is y=-4x+7
that is my standard form
another standard form is
y+4x=7
Answer:
(24, 224 ) i.e. 24 basketball and 224 footballs
Step-by-step explanation:
<em>Basketball :</em>
uses 4 ounces of foam
20 minutes of labor
profit = $2.50
<em>Football :</em>
uses 3 ounces of foam
30 minutes of labor
profit = $2
Manufacturer has :
768 ounces of foam , 120 labor hours per week,
<u>using the simplex method to determine the optimal production schedule so as to maximize profits </u>
lets assume
x = number of basketball
y = number of footballs
maximize = 2.5 x + 2y from a linear programming problem
attached below is the detailed solution
