Answer: The unit rate is $25
Step-by-step explanation: We know that the cost of cabin lodging is 25 dollars per lodger.
Then the equation y = 25x models this relation.
Here the cost is y, and the number of lodgers is x.
We want to find the unit rate.
The actual equation should be in dollars, and the number of lodgers is just a scalar number.
so the equation should be:
y = $25*x
Now, the unit rate is defined as the rate with 1 in the denominator, in this case, is the price for each unit of x (lodgers) so is the price per lodger.
We already know that the price per lodger is $25, so the unit rate is $25.
Answer:
y = -2x +15
Step-by-step explanation:
The point-slope form of the equation for a line through (h, k) with slope m is ...
... y - k = m(x - h)
For your point (h, k) = (5, 5) and slope m = -2, the equation in point-slope form is ...
... y - 5 = -2(x - 5)
Simplifying, we get
... y - 5 = -2x +10
Adding 5 puts the equation into slope-intercept form, as you want.
... y = -2x +15
Answer:
x³ + 2x² - 19x - 20
Step-by-step explanation:
x + 1 = 0
x = -1
Substitute x = (-1) in the polynomial
x³ + 2x² - 19x - 20 = (-1)³ + 2*(-1)² - 19 *(-1) - 20
= -1 + 2 +19 - 20
= -1 - 20 + 2 + 19
= -21 + 21 = 0
So, (x + 10 ix a factor of x³ + 2x² -19x - 20
