Answer:
$16.10
Step-by-step explanation:
Simply take the original cost and multiply it by the percentage to get the tip amount then add it all together.
14 × 15% = 2.1
14 + 2.1 = 16.1
This means the haircut would cost a total of $16.10.
Answer:
$1,050 because 150x7=1,050
Step-by-step explanation:
I think (x-1).Tell me back whether it is correct or not.
Answer:
Domain: {-3, -2, -1}
Range: {-3, 6}
General Formulas and Concepts:
- Domain is the set of x-values that can be inputted into function f(x).
- Range is the set of y-values that are outputted by function f(x).
Step-by-step explanation:
<u>Step 1: Define</u>
(-3, 6)
(-2, -3)
(-1, 6)
<u>Step 2: Identify x-values</u>
x = -3, -2, -1
<u>Step 3: Identify y-values</u>
y = -3, 6, 6
Answer:
C. two real solutions
Step-by-step explanation:
Your quadratic matches the form ...
ax^2 +bx +c = 0
for the values a=2, b=7, c=-15.
The discriminant is ...
d = b^2 -4ac
For your values of a, b, c, the discriminant value is ...
d = 7^2 -4(2)(-15) = 169
The discriminant is positive, indicating there are two real solutions.
_____
When the discriminant is negative, there are no real solutions, only complex solutions.
When the discriminant is zero, there is one real solution.
__
This equation factors as (2x-3)(x+5) = 0 and has solutions x=3/2, x=-5.
