Answer:
Step-by-step explanation:
(a) Carl earns $42 per 3 hours as given. To find the amount he earns per hourdivide:
$42/3 hours = $14/hour
(b) To see how much Louis makes per hour, simply plug in 1 for the hours value x:
y = $11(1 hours)
y = $11/hour
Thus Carl makes more than Louis.
(c) The equation of Carl's dollars per hour is similar to Louis' = 14x
where x is the number of hours he works and y is the number of dollars he earns. Plug in whole number values of hours for x and plot the points (x, y) on a graph
Is him in your bias?
Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 4) and (x₂, y₂ ) = (- 6, - 2)
m = 
= 
= -
Answer:
Step-by-step explanation:
The question makes sense for all values of x, but I imagine that is not exactly what you mean.
I think you mean for what values of x does the question produce a real square root?
The answer is as long as x + 2 does not drop below 0, the results will be real.
Put mathematically x ≥ -2 gives a real result. For now just don't try and take the square root of a minus number.
Answer:
x = 1
Step-by-step explanation:
4(2x + 1) - 3 = - 3(x - 4) ← distribute parenthesis on both sides
8x + 4 - 3 = - 3x + 12
8x + 1 = - 3x + 12 ( add 3x to both sides )
11x + 1 = 12 ( subtract 1 from both sides )
11x = 11 ( divide both sides by 11 )
x = 1
