Answer:

(-2,6)

Step-by-step explanation:

The solution to the system of equations should be true for both equations. This means that if you substitute -2 into both equations, you should get 6 as the y value for both equations.

They gave you a graph, and to find the solution from the graph, you just look at which point is shared by both lines, or at which point both lines intersect.

There is also a mathematical way to do it using substitution and elimination, but you should master the graphing method first before moving onto those.

The dimensions of a rectangle can be given by x+9 and x-2. If the area is 60ft^2, what is the value of X?

Veronika [31]

Answer:

Step-by-step explanation:

(x + 9) * (x - 2) = 60

x^2 - 2x + 9x - 18 = 60

x^2 + 7x - 18 = 60

x^2 + 7x = 78

FACTORING:

x(x + 7) = 78

x = 6

Position vectors m and n have terminal points of (2, ) and (1, y), respectively.

OLEGan [10]

This problem involves the dot product.

You must provide all info for position vector m. Your (2,) is inadequate.

Supposing that the terminal point of vector m were (2,3), then

m dot n would equal 8, or 8 = 2*2+3*y. Then 8 = 4 + 3y, and 4 = 3y, and y =3/4.

Please type in the terminal point of vector m and then answer this question following the above example.
