Answer:
y=3/4x-2.5
Step-by-step explanation:
This is a straight line, so it would follow the equation y=mx+b. You can find the b value by looking at the y-intercept of the equation (where x=0), which in this case would be -2.5. Then, you can find the m value by comparing the two given points' locations. Slope is rise over run, so first you can find the rise. The y value moves from y=-4 to y=2, which is a value of 6 units upward. The points move from x=-2 to x=6, which is a distance of 8 units. Finally, put it into the rise over run pattern, giving you 6/8, which simplified is 3/4. This is your m value. Finally, plug in your two variable values into y=mx+b and you'll get y=3/4x-2.5.
Answer:
we can do it by simplifying 8 to 
to make both powers base two, and subtracting the exponents.
Step-by-step explanation:
We have been given the expression 
8 can be rewritten as
Hence, the given expression becomes
After subtracting the exponents on left hand side of the equation we get:
we can do it by simplifying 8 to to make both powers base two, and subtracting the exponents.
it's either 2/3 or 66.6 (neverending 6s)
Answer:
Step-by-step explanation:
<em>a</em> - side of square
The formula of a perimeter of a square:
We have P = 48. Substitute:
<em>divide both sides by 4</em>
You can use the Pythagorean theorem, and calculate the length of a diagonal or use the formula of a diagonal of a square:
Substitute:
