Pls help and show workings <br> Due ASAP
tester [92]

Answer: B

Step-by-step explanation:

The equation y+2=\frac{3}{4} x-8 is not yet in slope-intercept form(y=mx+b).  Simply subtract 2 from both sides to turn the equation into slope intercept form as y=\frac{3}{4}x-10.  For a line to be perpendicular to another, it must have an opposite reciprocal slope.  A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa.  Thus, 3/4 would become 4/3.  The opposite reciprocal of 3/4 would be -4/3.

The slope of the line given is 3/4.  Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: y=-\frac{4}{3} x+b.  Then, because the line passes through -12, 1, plug those values in for x and y, respectively.  

1=-\frac{4}{3}*-12+b

1=16+b

-15=b

Thus, the equation of the line is y=-\frac{4}{3} x-15, or B.

Hope it helps :D

Find slope of m and y intercept of the graph of x+5y=20
Yakvenalex [24]
The answer is -1/5 because you have to switch the x to the other side making it a negative. Then you have to divide everything by 5 making your answer y=-1/5+4

How might snakes running out of food affect other organisms such as hawks? please help
marissa [1.9K]

Answer:

The population of Hawks and other species would likely start to edge off.

Step-by-step explanation:

Commonly, a Food Chain is dependent on all the parts of it sataying at a perfect point. If the food that the Snakes eat starts to run out, more of them will die off. With less Snakes, the Hawks will then have less food, and that continues throughout the chain. The same thing would happen if there was too much food, except instead of the populations of species dying off, the Snake population would spike.
