{4x+2y=10 y=2x-1 What is the value of x+y A.3.125 B.2 C.4.5 D.3.5

Evgen [1.6K]

Answer:

D.3.5

Step-by-step explanation:

4x+2y=10(given)

2x+y=5

y=5-2x-----(1)

y=2x-1------(2)(given)

Since the left side of the equations are the the same,

5-2x=2x-1

4x=6

x=1.5

Sub x=1.5 into eq(1),

y = 5-2(1.5) = 5-3 = 2

so, x+y = 1.5+2 = 3.5

Determine the line described by the given point and slope (0,0) and 2/3

AlekseyPX

Answer:

The line is $y=\frac{2}{3} x$ .

Step-by-step explanation:

Given:

Point and slope (0,0) and 2/3.

Now, to determine the line.

Here the point is:

$(x_{1},y_{1}) =(0,0)$

And the slope is:

$m=\frac{2}{3}$

Now, putting the formula and substituting the value from above to determine the line:

$y-y_{1} = m(x-x_{1})$

$y-0=\frac{2}{3}(x-0)$

$y=\frac{2}{3} x$

Therefore, the line is $y=\frac{2}{3} x$ .
