Answer:
The x-intercept it (-1.5, 0) and the y-intercept is (0, 3). The slope is 2.
Step-by-step explanation:
Answer: a = 150
b = 30
Remember: supplementary angles always add up to 180 degrees. Therefore, using this information, you can easily form your equation.
Form your equation. Since a is five times b, a = 5b.
5b + b = 180 Combine like terms
6b = 180 Divide by 6 to both sides
b = 30 Answer!
Substitute (30) for b in a = 5b to find a.
a = 5(30) Simplify
a = 150 Answer!
Answer:
4 hours
Step-by-step explanation:
Write an equation
19 +1.5x < 15+2.75x
Subtarct 15 on both sides
4+1.5x<2.75x
subtract 1.5x on both sides
4< 1.25x
Divide 1.25 on each side
3.2<X
Since they on,y charge per hour so 4 hours
Exponents are hard but think about it like addition, that number tells you how many times to add that number to itself. To write the equation put the number and then the exponent on the top right of that number. Your welcome!
Answer:
Plan A every two hours and Plan B every hour
Step-by-step explanation:
Plan A 3 hours Friday and 9 hours Saturday - total of 12 hours and he worked a total of 6 hours. 12/6=2
