In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.
<em>Multiply -4 and -3 in the function above.</em>
<em>Add 3 on both sides of the equation.</em>
<em>Add 2y on both sides of the equation.</em>
<em>Divide both sides of the equation by -3.</em>
Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.
Answer:
f(-3) = -5

Answer:
D
Step-by-step explanation:
7^-2 = 1/7^2
The negative means you flip it
1/7^2 times 7^6 is 7^6/7^2 (just multiply).
using rules of exponents, 7^6/7^2 is 7^4 (just subtract 2 from 6)
D is the only one that equals 7^4, as 2 times 2 is 4.
Answer:
B. 8 times the difference of a number <em>z</em> and 6
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Translate (z - 6)
<em>z </em>= a number <em>z</em>
- = difference
6 = six
(z - 6) = The difference between a number <em>z</em> and 6
Step 2: Translate 8(z - 6)
(z - 6) = The difference between a number <em>z</em> and 6
Since we are distributing the 8, we are multiplying.
8 times the difference of a number <em>z</em> and 6
Answer:
if it's less than 7.66km use Royal, if more than 7.66 use Queen's
Step-by-step explanation:
To get the answer you can set up mutliple equations
For Queen's Cab Company
2.70 + 0.20x = ?
for Royal Cab Company
1.55 + 0.35x = ?
Since you didn't give a distance which is what will determine which is cheaper we can solve as a set of equations.
2.70 + 0.20x = 1.55 + 0.35x
1.15 = .15x
x = 7.66
So this lets you know that at 7.66 km Royal cab company becomes more expensive due to their pence per km.
So if it's less than 7.66km use Royal, if more use Queen's
