Answer:
4
Step-by-step explanation:
The quadratic formula is x equals negative b plus or minus the square root of b squared minus four times a times c, all over 2a.
Looking at the equation, we can find the values for a, b, and c
a=7
b= -10
c= -2
So then putting that back into standard form, which is ax^2+bx+c, we know Haley's function in standard form is 7x^2-10x-2

Mr. Peterson
Step-by-step explanation:
u and one
Answer:
y=mx+c, m represents the slope while c the y-intercept. (never forget that)
Say the apprentice earns x dollars an hour, and the plumber earns x+15 dollars per hour. Write the equation:
40(x+x+15)=2200
Dividing by 40, we see that:
2x+15=55
Subtracting 15, we see that 2x=40, so x=20. As a result, the apprentice earns $20 an hour, and the plumber earns #35 per hour.
