Answer:
7x^2 −12x−10
Step-by-step explanation:
((5x2 - 8x) + 1) + (2x2 - 4x - 11)
Factoring 7x2-12x-10
The first term is, 7x2 its coefficient is 7 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is -10
Step-1 : Multiply the coefficient of the first term by the constant 7 • -10 = -70
Step-2 : Find two factors of -70 whose sum equals the coefficient of the middle term, which is -12 .
-70 + 1 = -69
-35 + 2 = -33
-14 + 5 = -9
-10 + 7 = -3
-7 + 10 = 3
-5 + 14 = 9
-2 + 35 = 33
-1 + 70 = 69
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Answer:
$17.64
Step-by-step explanation:
$15.50 and $5.50
with 20% off
and 5% sales tax.
take the 20% first.
(15.50 + 5.50) * ( 100 - 20) % = 21 *0.8 = $16.80
now add the tax
0.05 * 16.80 + 16.80 = $17.64
<span>They both forget about which way is North, and the needles point at each other.</span>
15 cherry, 17 grape, and 14 orange....total of 46 juice boxes
P(cherry) = 15/46
without replacing
P(grape) = 17/45 (I put it over 45 because since the 1st was not replaced, we have 1 less juice box)
P (both events happening) = 15/46 * 17/45 = 17/138 <==
Answer:
a. 
b. 17 years
c. The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.
Step-by-step explanation:
a.
Here, x is a the number of years after 2000 and f(x) is the total cost.
To approximate the yearly cost of attending a two-year college in the year 2016, find 
.
b.
To predict in what year the yearly cost of tuition and required fees will exceed $3200, solve 
So,
x is approximately equal to 17 years.
c.
The present year is 2020.
To approximate the yearly cost of attending a two-year college in the present year, find 
The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.
