-3x + y = 22 -12x – 10y=-10

Mathematics
1 answer:
dimaraw [331]3 years ago
8 0

Answer:

<h3>               x = -5,  y = 7</h3>

Step-by-step explanation:

-3x + y = 22     ⇒  y = 3x + 22

-12x - 10y = -10  and  y = 3x + 22

-12x - 10(3x + 22) = -10

-12x - 30x - 220 = -10

               +220       +220

 - 42x  = 210  

 ÷(-42)     ÷(-42)

    x = -5

y = 3(-5) + 22 = -15 + 22 = 7

In the xy- plane, the graph of the equation y + 3x + 5 is a line that intersects the y-axis at (0,b) what is the value of b?
maxonik [38]

Answer:

b=5

Step-by-step explanation:

The given equation is:

y=3x+5

To find the point where this line intersect the y-axis, we put x=0 into the given equation.

When x=0, we have y=3(0)+5.

This implies that; y=5.

The y-intercept is (0,5).

Comparing (0,5) to (0,b), we can conclude that; b=5
