Answer:
see below
Step-by-step explanation:
we are given a exponential function
we want to figure out the missing values of y for x i.e (-2,-1, and 2) to do we can consider substituting so,
when x is -2 y should be
rewrite ⅕ in exponent notation:
by law of exponent we obtain:
simplify square:
when x is -1:
rewrite ⅕ in exponent notation:
use law of exponent which yields:
when x is 3:
by law of exponent we obtain:
simplify square which yields:
Answer: The coordinates of the midpoint (1.5, -0.5)
Step-by-step explanation:
For the x-coordinate, find the difference between -1 and 4. That's 5. Take half of 5 and add to -1. So -1+2.5= 1.5
For the y-coordinate, the difference between -6 and 5 is 11. Half of 11 is 5.5. Add -6 + 5.5= 0.5
You have to divide both sides by 2/3, and by doing that you'll get w= -5/4
Answer: 1/3 pound pecans and 2/3 pound walnuts.
Explanation:
x ==> weight of walnuts
y ==> weight of pecans
║ x + y = 1
║ 8x +2y = 6
║ x = 1 - y
║ 8x + 2y = 6
8(1 - y) + 2y = 6
8 - 8y + 2y = 6
6y = 2
y = 1/3
x = 1 - 1/3 = 2/3
