Answers:
<h3>1. -5</h3><h3>2. 7</h3><h3>3. 1</h3><h3>4. 5</h3>
Step-by-step explanation:
Plug in the x into the equation and solve.
<h3>Value 1: X = 5</h3>
Y = -2(5) + 5
Y = -10 + 5
Y = -5
<h3>Value 2: X = -1</h3>
Y = -2(-1) + 5
Y = 2 + 5
Y = 7
<h3>Value 3: X = 2</h3>
Y = -2(2) + 5
Y = -4 + 5
Y = 1
<h3>Value 4: X = 0</h3>
Y = -2(0) + 5
Y = 0 + 5
Y = 5

Answer:
$2.50
Step-by-step explanation:
Jake's total expenditure is ...
total = admission + c × (number of tickets)

Answer:
x = 33/5
Step-by-step explanation:
x - 3/5 = n.......n = 6
so we sub
x - 3/5 = 6......add 3/5 to both sides
x = 6 + 3/5...convert using common denominator of 5
x = 30/5 + 3/5
x = 33/5 <===
check...
x - 3/5 = 6
33/5 - 3/5 = 6
30/5 = 6
6 = 6 (correct)...so it checks out
