Answer:
y+13 = 5(x+2)
Step-by-step explanation:
y = 5x-3
The slope is 5 since it is in the form y= mx +b where m is the slope
The point slope form of the equation of a line is
y-y1 = m(x-x1) where (x1,y1) is the point
y--13 = 5(x--2)
y+13 = 5(x+2)
First you divide the smaller number by the larger number, to see how many of that number goes into the other:
45/50 = 0.9
The you times it by 100 to get the percentage:
0.9*100 = 90%
Hope this helps! :)

Answer:
the one real zero is in the interval (-1, 0)
Step-by-step explanation:
Descartes' rule of signs tells you there are 0 or 2 positive real zeros. Changing the signs of the odd-degree terms and applying that rule again tells you there is one negative real zero. At the same time, those coefficients (-3, -5, -5, +7) have a negative sum, so you know ...
f(-1) = -6
f(0) = +7
so there is a zero in the interval (-1, 0).
__
You can try a few values between x=0 and x=10 to see what the function does in that part of the graph. You find ...
f(1) = 10
f(2) = 21
f(3) = 58
So, it is safe to conclude that there are no real zeros for x > 0.
The only real zero of f(x) is in the interval (-1, 0).
