You have to make a equation like 15m+5m=1800 and substitute m for 150 (m for dollars per hour. or whatever letter you want) and solve from there

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -x² - 2x + 2
f(x + 3) is x = x + 3
<u>Step 2: Find</u>
- Substitute in <em>x</em>: f(x + 3) = -(x + 3)² - 2(x + 3) + 2
- Expand: f(x + 3) = -(x² + 6x + 9) - 2x - 6 + 2
- Distribute -1: f(x + 3) = -x² - 6x - 9 - 2x - 6 + 2
- Combine like terms: f(x + 3) = -x² - 8x - 13
Answer:
Step-by-step explanation:
first you get your equations, because the game sums are based upon the st louis cardinals we will use them as x.
According to the problem the yankees won 3 fewer (-3) that 3 times (3x) the st louis cardinals which brings their equation to 3x-3
The sum of these to equations equals 37
37=x+3x-3
when you solve, you get x=10
then you plug it into the DIFERENT equations
3(10)-3=27 (yankees)
x=10
then check using your preffered method
4.0987 rounded to the nearest tenth.
4.0987
^ This is the tenths place
Look at the number after it, if it's 5 or more, round up, if it's 4 or less, round down.
<span>It's 9, so we round up to 4.1</span>
Answer:
A = 52°, a = 149.2, c = 174.3
Step-by-step explanation:
Technology is useful for this. Many graphing calculators can solve triangles for you. The attachment shows a phone app that does this, too.
___
The Law of Sines can give you the value of c, so you can choose the correct answer from those offered.
c = sin(C)·b/sin(B) = sin(113°)·49/sin(15°) ≈ 174.271 ≈ 174.3 . . . . . third choice
