Answer:
(0, 4)
x = 0
y = 4
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
12x - 5y = -20
y = x + 4
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 12x - 5(x + 4) = -20
- Distribute -5: 12x - 5x - 20 = -20
- Combine like terms: 7x - 20 = -20
- Isolate <em>x</em> term: 7x = 0
- Isolate <em>x</em>: x = 0
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x + 4
- Substitute in <em>x</em>: y = 0 + 4
- Add: y = 4
Answer: The total is $12,250.
Step-by-step explanation: First, we will calculate the amount that Hillary has deposited over the past 35 years. She has deposited $200 for each of the past 35 years. The total that she has deposited is 200 x 35 = $7,000.
Her employer also deposits into her account 75% of what she has deposited. In order to calculate their contribution you need to multiply $7,000 x .75 = $5,250.
The total that has been deposited into the account is $7,000 + $5,250 = $12,250.
Answer:
bot 2
Step-by-step explanation:
first find out how many clicks they do in 1 second
16 ÷ 2 = 8
30 ÷ 3 = 10
so know we know that bot 2 clicks 2 more rimes in a second than bot 1
so if we times both the numbers by 10 to find out how many times they click in 10 secs
so bot 1 clicks 80 times
bot 2 clicks 100
