Answer:
$7.10
Step-by-step explanation:
1 bar = $1.29
10 bars = 10 x $1.29 = $12.90
Change received = $20 - $12.90 = $7.10
Answer:
|x| > 1
Step-by-step explanation:
The absolute value inequality
|X| > k
where X is an expression in x and k is a non-negative number is solved by solving the equivalent compound inequality
X < -k or X > k
Here you are working backwards. You know you want the compound inequality to be
x < - 1 or x > 1,
so using the variable expression x for the expression X and 1 for k, write the absolute value equation
|x| > 1

Answer: -76 (choice C)</h3>
Explanation:
We're applying the dot product.
u dot v = 3*(-4) + (-8)*8
u dot v = -12 - 64
u dot v = -76
The idea is that we multiply the x coordinates together, and the y coordinates together separately. Afterward you add the products. The result of any dot product is a scalar value, aka a single number.
The dot product is useful in many applications. One of which is to determine if two vectors are orthogonal.
Answer:
−
6
Step-by-step explanation:
(x+4)/(x-2) >0
multiply both sides by x-2
x+4 > 0
subtract 4 from both sides
x > - 4
the solutions to this inequality are
x< −<span>4 or x>2
