Answer:
Cost per night: 75
Equation: 
Step-by-step explanation:
An equation to represent the situation can be written in the slope-intercept form,
, where,
m = slope of the graph, which is the rate per night.
b = y-intercept, which is the initial fee. It is the point where the line intercepts the y-axis.
Let's find m, using two points on the line, (2, 200) and (4, 350)

✅The cost per night = 75
y-intercept, b, = 50. The line intercepts the y-axis at y = 50, when x = 0.
Substitute m = 75, and b = 50 into
.
✅The equation would be:

Answer:
Rounding x = 5.52
Step-by-step explanation:
2.1x - 3.6 = 8
Add 3.6 to each side
2.1x - 3.6+3.6 = 8+3.6
2.1x = 11.6
Divide each side by 2.1
2.1x/2.1 = 11.6/2.1
x =5.523809524
Rounding x = 5.52
Since the Davis family put a $20,000 down payment on the house they purchased and also took out a $265,000 mortgage, that means the purchase price of the house is $285,000. To budget 1% of purchase price means about $2,850 for the year to pay for unexpected expenses.
si te entiendo pero no se como aser eso
To evaluate the expression we proceed as follows;
(7x³-16x+8)-(4x³-6x²+8x-9)
opening the parenthesis we have:
7x³+0x²-16x+8-4x³+6x²-8x+9
putting like terms together we get:
(7x³-4x³)+(-16x-8x)+(8+9)+(0x²+6x²)
=3x³+6x²-24x+17
the answer is
=3x³+6x²-24x+17
