Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)
Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8
Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
<span>a) if the bacteria double every hour then it would 2^t(1200) where t is hours and 1200 is the amount in there to begin with.
b) assuming the formula is correct it would be 2^24(1200). this becomes 20132659200 total in a day.</span>
Answer:
The amount of discount $70
New price $130
Step-by-step explanation:
To find how much 35% of 200 is, we multiply 200 with 35 then divide it with 100
200 × 35 ÷ 100 = 70 the bike's price is reduced by 70$ and the new price
20ü - 70 = 170$
Answer:
Fourth option y = x²
Step-by-step explanation:
It is clear from the graph that parabola passes through origin, which is it's vertex and line of symmetry is y-axis.
So the equation of the parabola will be y = (x - 0)² + 0
This equation of the parabola is in the vertex form [ y = (x - h)² + k]
Therefore, equation of the parabola will be y = x²
This equation is true for the given values of x and y in the table.
For (-2, 4) ⇒ 4 = (-2)²
For (-1, 1) ⇒ 1 = (-1)²
Fourth option y = x² is the answer.
