Answer:

930 is equivalent to 310 because 9 x 10 = 30 x 3 = 90. 1240 is equivalent to 310 because 12 x 10 = 40 x 3 = 120.

If x and y satisfy both 9x+2y=8 and 7x+2y=4, then y=?
Alex

Answer:

The value of y is -5

Step-by-step explanation:

we have

9x+2y=8 ------> equation A

7x+2y=4 ------> equation B

we know that

If x and y satisfy both equations, then (x,y) is the solution of the system of equations

Using a graphing tool

Remember that

The solution of the systems of equations is the intersection point both graphs

The intersection point is (2,-5)

therefore

The solution of the system of equations is the point (2,-5)

The value of y is -5

What is the equation that represents the line?
Kryger [21]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 6) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line

m = \frac{-3+6}{2+2} = \frac{3}{4}, thus

y = \frac{3}{4} x + c ← is the partial equation

To find c substitute either ot the 2 points into the partial equation

Using (2, - 3), then

- 3 = \frac{3}{2} + c ⇒ c = - 3 - \frac{3}{2} = - \frac{9}{2}

y = \frac{3}{4} x - \frac{9}{2} ← equation of line
