6x + y = -2<br> y= -3x + 1<br><br> Graph the solution
Gala2k [10]
6x + y = -2
y = -3x + 1

Substitute the value of y in first equation, 
6x -3x + 1 = -2
3x = -2-1
x = -3/3
x = -1

Now, Substitute it in 2nd equation, 
y = -3(-1) + 1
y = 3+ 1 = 4

Coordinates would be: (-1,4) Mark that point and join with origin.

Hope this helps!

What is the function rule that describes the pattern in the table?
Semmy [17]
The answer is D. You can rule out A and B by looking at the x value of 0 because the corresponding y value is 7 so you need to add 7 to a number multiplied by 0. And then you know it's not C because if you plug in the 0 for x it doesn't work.

Khalaf wants to know the length of a tunnel built through a mountain. To do so, he makes the measurements shown in the figure be
IRINA_888 [86]

Answer:

237.9 meters

Step-by-step explanation:

Let x represent the length of the tunnel.

Applying the Cosine Law, we have:

x² = 201² + 146² - 2*201*146*Cos(85)

x² = 61,717 - 58,692*0.0872

x² = 61,717 - 5,117.9424

x² = 56,599.0576

x = √56,599.0576

x = 237.9 m (nearest tenth)
