Answer:
y= 7x-73
Step-by-step explanation:
the equation form is y=mx+c where m is the slope and c a constant
m= (25-(-10))/14-9 = 35/5 = 7
so y= 7x+c
replace x and y by 14 and 25 respectively
25 = 7*14+c
c= 25-7*14
c = -73
so y= 7x-73
Answer: 54 ft²
Step-by-step explanation:
Area of a kite is calculated by the formula:
= (Length * Height) / 2
Length = 6 + 6 = 12 ft
Height = 9 ft
Area = (12 * 9) / 2
= 108 / 2
= 54 ft²
<u>Define x:</u>
Let Fred had x dollar.
Fred = x
Greg = x + 17
<u>Solve x :</u>
x + x + 17 = 85
2x + 17 = 85
2x = 68
x = 34
<u>Find the amount each of them had:</u>
Fred = x = $34
Greg = x + 17 = 34 + 17 = $51
Answer: Greg had $51
