1/3^5
Explanation
Subtract the exponents
Since the exponent is negative
It stays in the bottom hence why the one is added
A=tip 1
b=tip 2
t=total tip
c-total cost
a+b=t
53+t=c
53*.06=a
53*.20=b
a=3.18
b=10.60
t=3.18+10.60
t=13.78
c=53+13.78
total cost=$66.78
Answer:
8 is the correct answer because coefficient lies before Exponent. Exponent is variable
So 8 is the coefficient.
Answer:
3x - 2y = 1
Step-by-step explanation:
Step 1: Find the slope
slope m = (y2 - y1)(/x2 - x1)
m = (4 - 1)/(3 - 1) = 3/2
Step 1: Use the formula y = mx + b to solve
This is slope-intercept form of a line. We have a slope of 3/2, and a point (x, y), which is (1, 1). Plug those values into the equation above and solve for b (the only variable we are missing
1 = (3/2)(1) + b
1 = 3/2 + b
1 - 3/2 = b
2/2 - 3/2 = b
-1/2 = b
Step 2: Rewrite the formula using the slope and the b value we just calculated
y = (3/2)x - 1/2
Step 3: Standard form of a line is ax + by = c, where a is a positive integer, so we rearrange the equation from step 2 to standard form.
y = (3/2)x - 1/2
-(3/2)x + y = -1/2 (subtract (3/2)x from both sides)
-3x + 2y = -1 (multiply by 2 to get rid of the fraction on x)
3x - 2y = 1 (multiply by -1 so a becomes positive)
