Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -x² + 10x - 6
f(-5) is x = -5
<u>Step 2: Evaluate</u>
- Substitute: f(-5) = -(-5)² + 10(-5) - 6
- Exponents: f(-5) = -(25) + 10(-5) - 6
- Multiply: f(-5) = -25 - 50 - 6
- Subtract: f(-5) = -75 - 6
- Subtract: f(-5) = -81

Answer:
Dylan will not have enough money. He needs $22.65 but only has $22.50
Step-by-step explanation:
If Dylan's mom replaces each dime with a quarter, then Dylan will have 90 quarters.
1 Quarter = $0.25
90 x .25 = $22.50
The game costs $20.98 plus 8% sales tax
So 20.98 x .08 = <em>$</em><em>1.6784</em>
20.98 + 1.6784 = $22.65
<em>Dylan</em><em> </em><em>will</em><em> </em><em>not</em><em> </em><em>have</em><em> </em><em>enough</em><em> </em><em>money</em><em> </em><em>because</em><em> </em><em>he</em><em> </em><em>only</em><em> </em><em>has</em><em> </em><em>$</em><em>2</em><em>2</em><em>.</em><em>5</em><em>0</em><em> </em><em>when</em><em> </em><em>he</em><em> </em><em>needs</em><em> </em><em>$</em><em>2</em><em>2</em><em>.</em><em>6</em><em>5</em>
