Answer:
Step-by-step explanation:
if you need to add 2 fractions
20/4+ 8/3
common denominator is 12
60/12+32/12=92/12= 7 8/12 =7 2/3
Answer:
1) 12h - 10
2) 63m + 54
3) 21z - 12
4) 77w - 54
5) -72n + 28
6) 20y + 63
7) -24g -72
8) -63w + 14
9) -21s
10) -6m -12

Answer:
Step-by-step explanation:
company 1- 26.50 + 0.15 a min for calls
Company 2- 14.50 + 0.25a min for calls
14.50+0.25=14.75$ 15.00$ 15.25$ 15.50$ 15.75$ 16
26.50+0.15=26.65$ 26.8$
26.50+t*0.15=14.50+t*0.25
t*0.1=12
t=120 mins
120x0.25=30.00+14.50=44.50
120x0.15=18.00+ 26.50=44.5=44.50
Description:
x^2 to mean x squared
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) =x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line
Answer: k = 13The smallest zero or root is x = -10
