help m.e please please
Answer:
(-3, -4)
Step-by-step explanation:
The solution is where the two lines intersect. Therefore, the x-coordinate is -3, and the y-coordinate is -4.
Another way to solve this would be to set the to equations equal to each other, so 2x+2 = -4. Therefore, 2x = -6, and x = -3. And from the second equation, y = -4.
2 x + y = 25 3 x − y = 15

Answer:
I got 0.00001693508 is that one of your answers?
Answer is below. Look at the steps to understand the answer.
Step 1.We'll need to combine like-factors for (3⁻⁴ × 3⁻⁶)⁴.
To do that, we'll combine the exponents and copy the base number.
In the term, the like terms are...
3⁻⁴ and 3⁻⁶.
Like I said, when we need to combine the like-factors, we'll combine the numbers. Combine the numbers like this:
(3⁻⁴⁽⁻⁶⁾)⁴
Step 1a.Add the exponents.
Remember the integer rule.
P + P = P
N + N = N
P + N = P
P + N = N
According to the rule, a negative + negative = negative. So...
-4 + (-6) = (-10)
Step 2.We now need to make the exponent (3⁻¹⁰) positive.
Rule: A⁻ᴮ = ¹⁄ₐᴮ
According to the formula, A is the base number and B is the negative exponent.
That being said...
A → 3
B → 10
Now, since we know what A and B is, let's change our equation.
⅓¹⁰
Step 3Bring down the exponent 4 then multiply.
10 · 4 = 40
Therefore, the answer is ⅓⁴⁰.
4. Mr. Downey used the function f(x) = -3x2 + 12x to model the flight of a glider. In Mr. Downey's
functions, x is the amount of time that passes in minutes and f(x) is the glider's distance from the ground in
feet. After how many seconds will the glider reach its maximum distance from the ground?
Answer: 120 seconds
Step-by-step explanation: In order to find the maximum value of a function, you can take the derivative of the function and equalize the result to 0.
f'(x)=(-3x^2 + 12x)'=-6x+12=0
x=2
When x is 2, the function will reach its maximum value.
f(2)=-3(2)^2 + 12.2 = -12 + 24 = 12
The maximum value (f(x)) is equal to 12 and the time passed is 2 minutes which is equal to 120 seconds.
Answer:
After 2 seconds
Step-by-step explanation:
Here is the screenshot of the parabola that formed from the quadratic equation.
As you can see the maximum point of the parabola reaches 12 feet after 2 seconds.
Also as stated in the question " After how many seconds will the glider reach its maximum distance from the ground?" We are trying to see at how many seconds the glider reaches the maximum point, not how many seconds until it lands.
Thus, the answer would be 2 seconds

Justin drinks 1 litter of water.He drank 2,000 litters at his game.How many during his game and his practice?Explain.
The question is incomplete. The complete question is :
Justin drinks 1 litter of water during the soccer practice. He drank 2,000 milliliters of water at his game. How many liters of water did he drink during his game and his practice? Explain.
Solution :
It is given that :
During practice, Justine drank = 1 liter of water
During game, Justine drank = 2000 milliliters of water
We know that,
1 liter = 1000 mL
Therefore, during the game, Justine drank :
1000 mL = 1 liter
∴ 2000 mL = 2 liter
So Justine drank 2 liters of water during his soccer game and 1 liter of water during his practice.
Marcus receives an inheritance of $3,000. He decides to invest this money in a 11 -year certificate of deposit (CD) that pays 5.0 % interest compounded monthly. How much money will Marcus receive when he redeems the CD at the end of the 11 years?
Marcus will receive $5,193.82 when he redeems the CD at the end of the 11 years.
What is compound interest?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
A=P(1+r/n[tex])^{nt}[/tex]
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
Marcus receives an inheritance of $3,000.
He decides to invest this money in an 11 -year certificate of deposit (CD) that pays 5.0 % interest compounded monthly.
P = $3,000
r =5%
t = 11 years
A=P(1+r/n[tex])^{nt}[/tex]
Substitute the values of P, r and t in the formula,
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,
Then solve the equation for A
A=P(1+r/n[tex])^{nt}[/tex]
A = 3,000.00(1 + 0.05/12[tex])^{(12)(11)}[/tex]
A = 3,000.00(1 + 0.0041666666666667[tex])^{132}[/tex]
A = $5,193.82
Therefore, Marcus will receive $5,193.82.

The population of village increases by 2% every year. The current population is 1000. What will be the population after 2 years?
Answer:
1040 approx
Step-by-step explanation:
Given data
Rate = 2%
Population= 1000
Time = 2 years
We can apply the expression below to find the population after 2 years
A= P(1+r)^t
Substitute
A= 1000(1+0.02)^2
A=1000(1.02)^2
A=1000*1.0404
A=1040.4
Hence the population is 1040 approx
