Need help on this question
MariettaO [177]

<u>Given:</u>

The two equations are 2x-5y=-7 and 5x-3y=11

We need to solve the equations using elimination method.

<u>Elimination method:</u>

Let us multiply the equation 2x-5y=-7 by 5, we get;

10x-25y=-35 ---------(1)

Now, multiplying the equation 5x-3y=11 by -2, we get;

-10x+6y=-22 --------(2)

Adding equations (1) and (2), we have;

\ \ \ 10x-25y=-35\\-10x+\ \ 6y=-22\\---------\\-19y=-57

      y=3

Thus, the value of y is 3.

Substituting y=3 in the equation 2x-5y=-7, we have;

2x-5(3)=-7

  2x-15=-7

          2x=8

            x=4

Thus, the value of x is 4.

Hence, the solution of the system of equations is (4,3)

Therefore, Option A is the correct answer.

Suppose you invest a certain amount of money in account that earns 3% annual interest. You also invest that same amount + $2000
Greeley [361]
First account: $6500
Second account: $8500

Set x is amount of money in first account
=> x + 2000 is money in second account.
X*3% + (x+2000)*4% = 535
=> x = (53500 - 8000) / 7
X = 45500 / 7 = 6500
=> account #1 = x = 6500
Acc #2 = x + 2000 = 6500 + 2000 = 8500

If the maximum value of y=-3x² + mx + 10 is 37, find the values of m.​
uysha [10]

Step-by-step explanation:

y = -3x² + mx + 10

dy/dx = -6x + m.

When dy/dx = 0, -6x + m = 0. => x = m/6.

We have y = -3(m/6)² + m(m/6) + 10 = 37.

=> -m²/12 + m²/6 = 27

=> -m² + 2m² = 324

=> m² = 324

=> m = 18 or m = -18.
