Answer:
$385.00 = $85.00 * 3.647 + $75.00
Step-by-step explanation:
The equation that best represents the situation is:
Total Cost = Hourly Rate x Repair Time + Diagnosis Fee
In this case, the hourly rate is $85.00 and the diagnosis fee is $75.00. We are given that the total cost is $385.00. Let's represent the repair time as "t" in hours.
So, we can write the equation as:
$385.00 = $85.00 * t + $75.00
To solve for the repair time "t", we need to isolate the variable.
First, we subtract $75.00 from both sides of the equation:
$385.00 - $75.00 = $85.00 * t
Simplifying, we get:
$310.00 = $85.00 * t
Next, we divide both sides of the equation by $85.00 to solve for "t":
$310.00 / $85.00 = t
Using a calculator, we find that t is approximately 3.647, which means the repair time is approximately 3.647 hours.
Therefore, the equation that best represents the situation is:
$385.00 = $85.00 * 3.647 + $75.00

Simplify:
8x−2=−9+7x
8x+−2=−9+7x
8x−2=7x−9
Subtract 7x from both sides.
8x−2−7x=7x−9−7x
x−2=−9
Add 2 to both sides.
x−2+2=−9+2
x=−7
subtract 7x from 8 x = x
add 2-9 = -7
now you have x= -7

y = m x + b and we need a standard form:
a x + b y = c
y = 1/8 x + 7 / * 8 ( we will multiply both sides of equation by 8 )
8 y = x + 56
- x + 8 y = 56 / * ( - 1 )
x - 8 y = - 56
The equation is y = 1/8x + 7
Standard form equation is Ax + By = C, where A > = 0.
First eliminate the fractions by multiplying the equation by 8
8y = x + 56
Subtract x from each side
-x + 8y = 56
SInce x coeficient can't be negative multiply the equation by negative one.
x - 8y = -56

remember that 45-45-90 triangle has sides of x,x and x√2
(legs are measure x and hypotonuse=x√2)
the legs are equal and are also the base and height
find the legs (x=leg)
hypotonuse=24
24=x√2
divide both sides by √2
24/(√2)=leg=base=height
volume=1/2 times base times heigth
V=1/2 times (24/√2) times (24/√2)
V=1/2 times (576/2)
V=576/4
V=144 units^2
answer is A
