1)
y = ax+b
6 = 3a + b
18 = 5a + b
b = 6 - 3a
18 = 5a + 6 - 3a
2a = 12
a = 6
b = 6 - 18
b = -12
f(x) = 6x -12
2)
y = 2
No, because y ≠ 4
x = 2
No, because it's vertical<span>
</span>
y = 4
Yes, because x ∈ <span>ℝ and y = 4
</span>
x = 4
No, because it's verical
Answer:
if its 2/7 then 98 the luck also counts so 20
Step-by-step explanation:
luck+98+the premtier
The mat adds 3 inches to each side, so the length would be 3+20 = 23 inches. The width would become 3 + 9 = 12 inches.Area = Length x width:
23 x 12 = 276 square inches
Answer: <span>-x2 + 120x = 1,800

She plans on using the side of the barn as one side of her paddock so it has 3 sides. Since the width is shorter, it will be more efficient to have 2 widths (1 lengths and 2 widths). Because J</span><span>ill has 120 feet of fencing to use, you can get this equation:
120ft= 1L +2W
</span>1L= 120-2W
If you insert it into area formula it would be:
area= L*W
area= (120-2W) *W
area= 120W- 2W^2
-2W^2+120W= area
<span>Since x represent the width of the paddock and the area is 1800 the equation become
</span>-2X^2+120X= 1,800
