Answer:
x = 3/4
Step-by-step explanation:
Step 1: Find possibilities.
- We know one possibility: 8x - 6 = 0. This is because 0 cannot be positive or negative.
Step 2: Solve possibility 1.
(Add 6 to both sides)
(Divide both sides by 8)
Therefore, x = 3/4.
Answer:
<h2>D) y = 2x - 5</h2>
Step-by-step explanation:
A partial variation is defined as a relation which has the form 
, where 
is the slope and 
is the y-intercept.
So, by definition, the right answer is D) y=2x-5, it's a partial variation, and it doesn't pass through the origin of the coordinate system.
Answer:
x=50
Step-by-step explanation:
x in (-oo:+oo)
(2/5)*x+10 = 30 // - 30
(2/5)*x-30+10 = 0
2/5*x-20 = 0 // + 20
2/5*x = 20 // : 2/5
x = 20/2/5
x = 50
x = 50
Answer:
Lien: $26300 Her husband: $24700
Step-by-step explanation:
x+(x+1600)=51000
2x+1600=51000
2x=49400
x=24700
Her husband earned 24700
24700+1600=26300
Lien earned 26300
Answer:
72 cm^3
Step-by-step explanation:
find the volume of the big block and the volumem of the smaller block and subtract it
(8 x 2 x 5) - (2 x 2 x2)
= 80 cm^3 - 8 cm^3
= 72cm^3
