Answer:
Step-by-step explanation:
a.) y = 25x + 15
b.) y is the total cost x is the amount of nights stayed 15 is the entrance fee and 25 is the cost per night
i.) x is the amount of nights stayed y is the total cost
ii.) slope (or m) is 25 y-intercept is 15
c.) plug in 3 for x
y = 25(3) + 15
y = 75 + 15
y = 90
its $90 for 3 nights
hope this helps <3
Multiply the first equation by 2 to then use elimination by adding the 2 equations.
So, 14x-2y=14
+. x+2y=6
Equals 15x=20 so x=20/15=4/3
Plug in to first equation to get y
7(4/3)-y=7
28/3-y=7
28/3-y=21/3
So y=7/3
Plug both x and y into second equation to check
4/3+2(7/3)=
4/3+14/3=18/3=6 it works
So x=4/3, y=7/3
Hope this helps! Have a blessed day!
The answer is D.
Y=2x Y=x(2)-3
2=2(1) 2=3(2)-3
2=2 2=6-3
2=2
Answer:
A
Step-by-step explanation:
First you simplify both sides to get -2.4x+14.4 > 52.8
then you need to subtract the 14.4 from both sides giving -2.4x> 38.4
then divide both sides by -2.4 giving an answer of
x is less than or equal to -16 meaning you point to the left with a closed circle
