Answer:
y = -1/7 x + 16/7
Step-by-step explanation:
Write in standard form of the equation of the line through the given points: through (2,2) and (-5,3)
Given the point (2,2) and (-5,3). The standard form of an equation passing through the points is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope
m = y2-y1/x2-x1
m = 3-2/-5-2
m = 1/-7
m = -1/7
Get the intercept. Substitute m = -1/7 and one of the point (2,2) into the expression y = mx+c
2 = -1/7(2) + c
2 = -2/7 + c
c = 2 + 2/7
c = (14+2)/7
c = 16/7
Substitute m = -1/7 and c = 16/7 into the expression y = mx+c
y = -1/7 x + 16/7
Hence the required equation is y = -1/7 x + 16/7
X+ 1.5x - 4.5 = 5/2
2.5x - 4.5 = 5/2
2.5x = 5/2 + 4.5
2.5x = 7
x = 7/2.5
X = 2.8
Answer: $83.16
Step-by-step explanation:
This means that next year the item will cost 154% of what it is now.
154% / 100 = 1.54
$54 * 1.54 = $83.16
Next year the item will cost $83.16.
<span>Part A:
</span>Surface area = 3.14(2*3 + 2²<span>)
</span><span>Part B:
</span>Surface area = 3.14(2*3 + 2²)
= 3.14(6 + 4)
= 3.14 * 10
= 31.4 units²
