The value of x and y which satisfies the equation : <br>-6x+7y=8​
aleksandr82 [10.1K]
Answer:
x=1
y=2

Explanation:
first start with assigning a random value to a variable
lets say x=1
from there the equation becomes solveable
-6x1+7y=8
simplify
-6+7y=8
+6 to both sides
7y=14
divide both sides by 7
y=2

from here we can say that x=1, y=2, can satisfy the equation-6x+7y=8

hope this helps :)

HELP!
max2010maxim [7]
For the first question, the total is 240 so that goes in front of the equals sign.  he has already worked 97 hours, so the expression on the right begins with 97 and adds the unknown number of hours, <em>h</em>, to it:
240 = 97 + <em /><em>h</em>

For the second question, there is no graph so I cannot answer it.
3rd question:  no image, can't answer.

4th question:
Use a factor tree:
                          240
                           /  \
                        10*24
                        /\     /\
                      5*2 *8*3
                    /   /    /\    \
                  5 * 2 *4*2 *3
                /     /    /\     \    \
             5   *  2 *2*2 * 2 * 3
Starting with the smallest factor and using exponents we have
2^4*3*5

From a train station, one train heads north, and another heads east. Some time later, the northbound train has traveled 12 miles
tigry1 [53]

9514 1404 393

Answer:

  20 miles

Step-by-step explanation:

The north and east distances form the legs of a right triangle. The straight-line distance between the trains is the hypotenuse of that triangle. The Pythagorean theorem can be used to find the length of the hypotenuse (d).

  d² = 12² +16²

  d² = 144 +256 = 400

  d = √400 = 20

The two trains are 20 miles apart.

__

<em>Additional comment</em>

You may recognize the given distances are in the ratio 3 : 4.  You may recall that side ratios of 3 : 4 : 5 make a right triangle. If so, you recognize that the straight-line distance is (4 miles)×5 = 20 miles. (3:4:5 right triangles show up often in algebra and geometry problems, so might be something you want to look for.)
