Please use "^" to indicate exponentiation:

<span>f(x)=x^2+10x+35

Complete the square:  </span><span>f(x)=x^2+10x+25-25+35 = (x+5)^2 +10

or y-10=(x+5)^2, so the vertex is at (-5,10).  h has the value -5.</span>

Pedro works as a newspaper deliverer. He receives a base pay plus an additional amount per newspaper delivered. Last week, Pedro
Gemiola [76]
Y = base pay + (variable pay * x)

37.50 = base pay + (variable pay * 5)
75 = base pay + (variable pay * 20)

let v be the variable pay: 
base pay = y - variable pay * x
37.50 - 5v = 75 - 20v
-5v + 20v = 75 - 37.50
15v = 37.50
v = 37.50/15
v = 2.5

37.50 - 5(2.5) = 75 - 20(2.5)
37.50 - 12.50 = 75 - 50
25 = 25

base pay is 25 ; variable pay is 2.50 per newspaper delivered.

y = 25 + 2.50x

Darius wrote 17 minus 2 to the second power equals 225. explain his error
sashaice [31]

Answer:

Darius took (17-2)^2 instead of 17-2^2, ignoring the order of operations. The answer is 13.

Step-by-step explanation:

To solve 17-2^2, Darius should first square two, then subtract that from 17. By subtracting 2 from 17 first, you ignore the PEMDAS rule (parenthesis, exponents, multiplication/division, addition/subtraction).

2^2=2

17-4=13

Jorie normally leaves work at 5:00 pm, but she is leaving work 30 minutes late today. She decides to make up time by taking the
coldgirl [10]

Answer:

y=x/4+30

Step-by-step explanation:

Let x be the normal time it takes for her to commute. We know that if she was 30min late, this would had 30 min to the journey. She takes a different route, she can travel four times faster than the normal route.

Therefore the normal time of commute will be 4 times less:

y=x/4+30

This equation states that the commute time will be four times faster and adding the 30min that she is late.
