Which graph represents the solution to this inequality?

1 answer:

7 0

In the second to last step, you end up with -x ≤ 13, but x can't be negative, so the sign is flipped, turning x positive and 13 negative, leaving us with x ≥ -13, which is why the line goes right.

What is (14x^2– 27x+9) / (7x-3)? A. 7x-3 B. 2x-3 C. -211x+9 D. 2x-33

Yakvenalex [24]

Answer:

B. 2x - 3

Step-by-step explanation:

$\rm \frac{ {14x}^{2} - 27x + 9}{7x - 3}$

$\rm = \frac{ \cancel{(7x - 3)}(2x - 3)}{ \cancel{7x - 3}}$

$\boxed{ \rm \bold{= 2x - 3}}$

1. Renting a bicycle at a local Bike shop costs $30 for the first day and $10 for each additional day.

Elza [17]

(a) Create a chart of values and write an equation to find the total cost, C in terms of the number of days d.

C = 10d + 20

(b) Use the equation you created in Part (a) to find the cost of renting a bike for 5 days.

C = 10d + 20
C = 10(5) + 20= 50 + 20 = 70

$70 for 5 days

a.
$2^2+3^2=(\sqrt{13})^2 \\
4+9=13 \\
13=13 \\ true$

b.
$2^2+2^2=4^2 \\
4+4=16 \\
8=16 \\
not \ true$

c.
$1^2+(\sqrt{3})^2=2^2 \\
1+3=4 \\
4=4 \\
true$
