Solve the simultaneous equations<br> y = 2x^2<br> y = 3x + 14
Mekhanik [1.2K]

Answer:

x = -2

And, x = 7 ÷ 2

Step-by-step explanation:

Given that

y = 2x^2

y = 3x + 14

Now equate these two above equations

2x^2 = 3x + 14

2x^2 - 3x - 14

2x^2 -7x + 4x - 14

x(2x - 7) + 2(2x - 7)

(x + 2) (2x - 7)

So it can be x = -2

And, x = 7 ÷ 2

Jamie receives 15% commission on magazine subscriptions. One week her sales totaled $860. What was her commission?
icang [17]

Given:

Jamie receives 15% commission on magazine subscriptions.

One week her sales totaled $860.

To find:

Her commission.

Solution:

We have,

Total sales of one week = $860

Rate of commission = 15%

Now,

Commission=\dfrac{15}{100}\times 860

Commission=\dfrac{15}{10}\times 86

Commission=\dfrac{1290}{10}

Commission=129

Therefore, the amount of commission is $129.
