Answer:
85 cents
Step-by-step explanation:
Let a represent the price of pineapples
Let p represent the price of peaches
74p + 9a= 14p + 21a
p = 17 cents
Substitute 17 for p
74(17) + 9a = 14(17) + 21a
1258+9a= 238+21a
1258-238= 21a-9a
1020= 12a
a= 1020/12
a= 85
Hence the price of pineapples is 85 cents
The expression in A is equal to:
y = 8 + 3x
It can be observed that the equation is in the slope-intercept form which is equal to,
y = mx + b
where m is slope and b is intercept.
The slope and intercept therefore of this equation of the line are equal to 3 and 8, respectively.
For Part B:
The slope of the line can be calculated through the equation,
m = (y₂ - y₁) / (x₂ - x₁)
Substituting,
m = (5 - 2)/ (0 - -1) = 1.5
The intercept, b, is the value of y when x = 0. From the tabulation, y = 5 when x = 0. Thus, the intercept is equal to 5.
Comparing the slopes and intercepts of the equations, we can say that the slope of the second is only half that of the first and the intercept of the second is 3 less than that of the first equation.

Step-by-step explanation:
49cm Would be your answer, sorry for the late reply
Answer:
Step-by-step explanation:
It usually works to follow directions.
a) Substitute the numbers into the formula:
v = u + at
49 = 0 +9.8t
b) Solve the equation:
49/9.8 = t = 5 . . . . . divide by the coefficient of t
