Answer:
B
Step-by-step explanation:
To find the slope m use any 2 ordered pairs from the table.
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 11) and (x₂, y₂ ) = (2, - 1)
m =
=
= - 2 → B
The relevant formula that we can use in this situation is:
v = v0 + at
where v is the final velocity, v0 is the initial velocity
= 20 km/hr, a is acceleration at 3.4 m/s^2 and t is time at 20 seconds
First convert v0 to m/s, v0 = 5.56 m/s
v = 5.56 m/s + 3.4 m/s^2 * 20 s
v = 73.56 m/s
Then convert back to km/hr:
<span>v = 264.82 km/hr</span>
Answer: Hi hope your new account doesn't malfunction.
Answer:
B. 
Step-by-step explanation:
The given quadratic trinomial is;

Comparing this to
, we have a=5,b=17,c=6.

Two factors of 30 that add up to 17 is 15 and 2.
We split the middle term to obtain;

We factor by grouping;

Factor further

The correct answer is B.
Answer:
7 shirts
Step-by-step explanation:
The function for producing shirts is
f($) = 50 + 7.5(x), where x is the number of shirt
The function for selling shirts is
f($) = 15(x)
For there to be a profit, he must make more money selling the shirts than he spent on making the shirts
Therefore, 15(x) > 50 + 7.5(x)
15x > 50 + 7.5x
15x - 7.5x > 50
7.5x > 50
x > 6.67 shirts
To make a profit, Juan must sell at least 7 shirts
