Find the 72nd term of the arithmetic sequence -27, -11, 5,
Answer:
1109
Step-by-step explanation:
an = d (n - 1) + c
an = what you're looking for
n = term position
d = the common difference, in your case, 16
c = first term of the sequence, or -27
a₇₂ = 16(72 - 1) + -27 = 1109

-3 is a zero for the polynomial:
x^3 + 7x^2 + 16 x + 12
True or False
Answer:
true
Step-by-step explanation:
If x = - 3 is a zero of the polynomial then f(- 3) = 0
f(x) = x³ + 7x² + 16x + 12
= (- 3)³ + 7(- 3)² + 16(- 3) + 12
= - 27 + 63 - 48 + 12
= 0
Since f(- 3) = 0 then x = - 3 is a zero of the polynomial

If gas costs $4.55 per gallon how many whole gallons of gas could you buy with $12.00?
The amount of gallons of gas that can be bought with $12 is 2.64 gallons.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Cost of gas per gallon = $4.55
This can be written as,
1 gallon = 4.55
Multiply 12/4.55 on both sides.
12/4.55 gallons = 12/4.55 x 4.55
2.64 gallons = 12
This means,
2.64 gallons for $12.
Thus,
2.64 gallons can be bought for $12.

Solve for a: -8b+2a=6c
Answer:
a=3c+4b
Step-by-step explanation:
-8b + 2a = 6c
(-8b + 2a) + 8b = 6c + 8b
-8b + 2a + 8b = 6c + 8b
-8b + 8b + 2a = 6c + 8b
2a = 6c + 8b
2a/2 = 6c + 8b/2
a = (2x3)c + [tex]2^{3}[/tex] x b)/2
a = 3c + 4b

9x - 4y= 19
4x + 4y= 20
Answer:
x=3 and y=2
Step-by-step explanation:
9x - 4y= 19
4x + 4y= 20
add both equations;
13x = 39
x= 3
using 4x + 4y= 20;
4(3) +4y=20
12+4y=20
4y= 20-12=8
y=8/4=2

18% discount on a list price of $25
Answer:
$20.50
Step-by-step explanation:
100% price - 18% discount = 82%.
82% can be written as .82
The original price was 25, so we multiply 25 by 0.82. We get $20.50.
If you are looking for the amount saved, subtract 20.5 from 25. We get $4.50.
