Answer:
Step-by-step explanation:
Put in the form of y = Ax + B
x + 2y = 10
2y = -x + 10
y = -½x + 5
has a slope of -½ and a y intercept of 5
-x + 4y = 8
4y = x + 8
y = ¼x + 2
has a slope of ¼ and a y intercept of 2
Answer:
A. Equation is ![c=25+15.75x](https://tex.z-dn.net/?f=c%3D25%2B15.75x)
B. Cost is $88
Step-by-step explanation:
A)
Suppose you rent for x hours and each hour costs $15.75
<u><em>How much would you need to pay?</em></u>
![15.75x](https://tex.z-dn.net/?f=15.75x)
Moreover, there is a $25 dollar (fixed) deposit for renting, so that gets added to your payment. All in all, you have to pay ![25+15.75x](https://tex.z-dn.net/?f=25%2B15.75x)
This is the equation of renting a snowboard for x hours.
Equation is ![c=25+15.75x](https://tex.z-dn.net/?f=c%3D25%2B15.75x)
- Where x is the number of hours you rent the snowboard, and
- c is the total cost
B)
If you are renting from 8.30 to 12.30, you are basically renting for 4 hours.
To know how much it will cost, you simply plug in 4 into x (in the equation):
![c=25+15.75x\\c=25+15.75(4)\\c=88](https://tex.z-dn.net/?f=c%3D25%2B15.75x%5C%5Cc%3D25%2B15.75%284%29%5C%5Cc%3D88)
Cost is $88
To find your answer, you just have to graph the points, then connect them to see what shape they make! :) Hope this helps!
50 = 1*50
50 = 2* 25
50 = 5* 10
the factors of 50 = 1,2,5,10,25, 50
x^2 =144 has 2 solutions
x=sqrt(144)
x=+-12
x= 12 and x=-12
12*12 = 144 and (-12) * (-12) = 144
a square root has 1 positive and 1 negative solution
x^3 = 27
(x^3)^(1/3)=(27)^(1/3) ^(1/3) is the cube root
x = 3
it only has one solution because a negative * a negative * a negative would be negative
