Answer:
232
Step-by-step explanation:
9 x 25 = 225 225 + 7 = 232
another way to find it
9 x 20 = 180 9 x 5 = 45 180 + 45 = 225 + 7 = 232
Answer:
x = 10 and x = -2
Step-by-step explanation:
The equation has 2 solutions because we have a square. When things are squares, we get a positive and negative solution.
(x-4)^2 - 28 = 8
Add 28 to each side
(x-4)^2 - 28+28 = 8+28
(x-4)^2 = 36
Take the square root of each side
sqrt((x-4)^2) = ±sqrt(36)
x-4 = ±6
Add 4 to each side
x-4+4 = 4 ±6
x = 4 ±6
x = 4+6 and x = 4-6
x = 10 and x = -2
15 represents the slope of the function. In other words it means that for every week Jerome earns 15 dollars more. Hope this helps :)
Answer:
y=4.5x+40
16 pairs of shoes
Step-by-step explanation:
Let the target earnings be represented by y and the number of pairs of shoes that Roger sells be x hence
y=4.5x+40
The equation is therefore, y=4.5x+40.
To solve this equation, substitute the value of y with 112 hence
112=4.5x+40
4.5x=112-40=72
x=72/4.5=16
Therefore, Roger should sell 16 pairs of shoes to achieve his target earnings of $112
