Given equation:
8.5d + 7.5 = 100 + 3Step 1, subtract 7.5 from both sides:
8.5d = 103 - 7.5Step 2, divide both sides by 8.5:
d = 95.5/8.5Correct answer choice is B

Which simplified equation below represents the equation of the line, y - y1 = m(x - x1), through the point (4,4) that is perpendicular to x - 3y = -18?
A: y = 2/3x + 8/3
B: y = -3x + 4
C: y = 1/3x + 4
D: y = -3x + 16
(I asked this already but some genius messed it up)
Answer:
D
Step-by-step explanation:
y-y1=m(x-x1) through (4,4)
x-3y= -18 is perpendicular : m1*m2=-1
y=mx+c
-3y=-18-x
3y= 18+x
y=x/3 + 6
y= 1/3x + 6
m1*m2= -1
m1= -1/m2
m1= -1/1/3
m1= -3
y- 4= -3(x - 4)
y-4= -3x +12
y= -3x +12+4
y= -3x + 16

Step-by-step explanation:
Axel and Carl both volunteer at a science museum. The manager needs one helper at a time for at most 18 hours this month. Axel wants to work at least 6 hours. The manager wants Carl to work no more than twice as many hours as Axel. Let a represent the number of hours that Axel works. Let c represent the number of hours Carl works. Which system of inequalities represents the constraints of this problem situation?
We want to find a system of inequalities that models the given situation.
We will find the system:
a + c ≤ 18
a ≥ 6
c ≤ 2*a
First we define the variables:
c = number of hours that Carl works.a = number of hours that Axel worksThe given information is:
The manager needs one helper at a time for at most 18 hours.
From this we can write:
a + c ≤ 18
Axel wants to work at least 6 hours.
a ≥ 6
The manager wants carl to work no more than twice as many hours as Axel.
c ≤ 2*a
The system is then:
a + c ≤ 18
a ≥ 6
c ≤ 2*a
