The cost of the ride varies by however many miles is driven, however the charging rate stays the same no matter how long the ride is. In the expression 0.20m + 2.00 , 2.00 is the constant as it stays the same, and 0.20 is the coefficient as is varies with however many miles are driven.
Answer:
A) y = -2x
B) y = x - 3
Step-by-step explanation:
A) you need to have a negative 'x' coefficient and no y-intercept
B) you need to have a positive 'x' coefficient and a negative y-intercept
When a line and a curve are tangent to each other, they are joined together by 1 point (x,y). So, you equate both equations either in terms of x or y. For this problem, let's equate in terms of y.
y = k - x
y = x² + 3x + 1
k - x = x² + 3x + 1
k = x² + 3x + x + 1
k = x² + 4x + 1
This would be the value of k. Since we are not given the common point, it can only be expressed in terms of x or y.
16 tens = 16 x 10 = 160 ones
The correct answer is
#2x^(-1/2)
