Answer:

Part A: y = 4.5x + 22

Part B: 31 inches

Step-by-step explanation:

Part A:

the y-intercept appear to be at 22

the slope can be found by using the points (0, 22) and (4, 39)

m = <u>39 - 22</u>

4 - 0

m = 17 / 4 = 4.3 and this is close to 4.5

Part B:

plug in 2 for 'x' in the equation: y = 4.5x + 22

y = 4.5(2) + 22

y = 9 + 22

y = 31

A pair of boots is 30dollars more than a pair of sandals. A pair of sandals cost s dollars each. Emily purchased 2 pairs of boot

babunello [35]

Answer: The expression representing the amount of money spent is $5x+60$ by Emily.

Step-by-step explanation:

Since we have given that

Let the cost price of per pair of sandals be 's'

Let the cost price of per pair of boots be 's+30'.

Number of pairs of boots = 2

Number of pairs of sandals = 3

Total cost would be

$2(s+30)+3s\\\\=2s+60+3s\\\\=5s+60$

Hence, the expression representing the amount of money spent is $5x+60$ by Emily.
