Answer:
y = 3/4x -7/4 or y = 0.75x -1.75
Step-by-step explanation:
The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points
y = 21/28(x -21) +14 . . . . . . . . . . . . . . . simplify a bit
y = 3/4(x -21) +14 . . . . . . . . . . . reduce the fraction
y = 3/4x -15 3/4 +14 . . . . . . . .eliminate parentheses
y = 3/4x -7/4 or y = 0.75x -1.75
He rode 6 rides times some number that cost 19.56, therefore
6x =19.56
Solve for x to find what the cost is or in this case the value of proportion.
X=3.26
Answer:
C
Step-by-step explanation:
The parabola faces downwards, so "a" will be negative. Using this information, we cancel out answer choice D and A. However in answer choice B, it uses y^2 instead of x^2 which is incorrect. Then, the only option you have left is C which is correct.
Answer:
(5/7 - 1) * (2/3 + (1/6 - 1/9) * 18/5 + 1/15) - (2/7 + 1/3) * (-7/13)
= (5/7 - 7/7) * (2/3 + (3/18 - 2/18) * 18/5 + 1/15) - (6/21 + 7/21) * (-7/13)
= (-2/7) * (2/3 + 1/18 * 18/5 + 1/15) - 13/21 * (-7/13)
= (-2/7) * (2/3 + 1/5 + 1/15) + 7/21
= (-2/7) * (10/15 + 3/15 + 1/15) + 1/3
= (-2/7) * 14/15 + 1/3
= -4/15 + 1/3
= -4/15 + 5/15
= 1/15
