y = x^2 + 5x -3

y-x =2

Replace y in the second equation with the first one:

x^2 + 5x -3 - x = 2

Simplify by combining like terms:

x^2 + 4x -3 = 2

Subtract 2 from both sides:

x^2 + 4x -5 = 0

Fctor the polynomial:

(x-1) (x+5) = 0

Solve for both X's:

x = 1 and x = -5

Now replace x in the second equation with both value and solve for y:

y -1 =2, y = 3

y - -5 =2, y +5 = 2, y = -3

Now combine the sets of answers:

(1,3) and (-5,-3)

The value
ehidna [41]

Answer:

A

Step-by-step explanation:

Check the solution by substituting x = \frac{\pi }{2} into the left side of the equation

2sin²x - sinx - 1

= 2sin²(\frac{\pi }{2} ) - sin (\frac{\pi }{2} ) - 1

= 2(1)² - 1 - 1

= 2 - 1 - 1

= 0

= right side

\frac{\pi }{2} is therefore a solution to the equation

Zabato is thinking of a number. Three times the sum of the number and ten is the same as eight time the number. What is zabato's
9966 [12]

Answer:

Zabato is thinking of 6

Step-by-step explanation:

I first set it up as an equation based on the word problem you have given me

(n + 10)3 = 8n

Distribute the 3

3n + 30 = 8n

Isolate n

3n - 8n +30 - 30 = 8n - 8n - 30

-5n = -30

-5n/-5 = -30/-5

n = 6

To check replace 6 with n

(6 + 10)3 = 8 (6)

(16)3 = 48

48 = 48
