Graph x+y=8 and x-y=4

Mathematics
1 answer:
yanalaym [24]3 years ago
8 0

Answer:

See attached photo for graphs.  

Step-by-step explanation:

The first step is to solve each equation for y, then graph using slop-intecept form...

x + y = 8

 

  y = -x + 8         (subtract x from both sides)

x - y = 4

   -y = -x + 4     (subtract x from both sides)

       y = x - 4       (divide both sides by -1)

Explanation would be appreciated. i don’t understand
katen-ka-za [31]

Answer:

28\sqrt{3}

Step-by-step explanation:

The area of the big triangle is 1/2 b h =  1/2*6*(12^2 = 6^2 + x^2)

that ends up being \sqrt{108}  = 36\sqrt{3}

the small triangle are needs to be subtracted....

\frac{\left(4\cdot \:sin\left(90\right)\right)}{sin\left(30\right)} that is the length of the unknown side...

1/2 B * h of that triangle get you to 8\sqrt{3}

just subtract the two areas

Rewrite the equation 6x + 7y = 14 into slope-intercept form (y = mx + b)
Tamiku [17]

rearrange into the form y = mx + b

subtract 6x from both sides of the equation

7y = - 6x + 14

divide all terms by 7

y = - \frac{6}{7} x + 2 → in slope- intercept form
