Answer:
The 3rd one 50 - 12p = 26
Step-by-step explanation:
1 foot = 12 inches
The 4 ribbons is 8 feet because each ribbon is 2 feet each
You would multiply the 8 ft by 12 to convert the feet to inches
8 ft. x 12in = 96in.
Then add the remaining ribbon
96 + 10= 106 inches of ribbon
As far a domain, you only care about the denominator and radicals.
f(x) = 2 - √x is the denominator, so it can't be 0.
Also x is under a radical, so x can't be negative.
Set the denominator equal to 0 to find the excluded values.
2 - √x = 0
-√x = -2
√x = 2
x = 4, so 4 is an excluded value
The domain is all real numbers greater than or equal to 0, except 4.
[0, 4) U (4, ∞)
0 ≤ x < 4 U x > 4
Answer:
Linear: y = 2x-1
Step-by-step explanation:
slope 1 = (5 - -9)/(3 - -4) = 14/7 = 2
slope 2 = (19-5)/(10-3) = 14/7 = 2
equation: y = mx + b b = y-mx = 19 - 2*10 = -1
y = 2x - 1
The first one is 10 the second one is 26
