Answer:
f(x)=0.5x+3.5, x<1
f(x)=-2x+6, x>1
Step-by-step explanation:
Find the Point of Interest, which is at x=1 because the direction changes. Find the slope (rise/run) of the line on the left which is 1/2 or 0.5. Find the y-intercept by plugging in the given point: (-3, 2). 0.5(-3)+c=2 so the y-intercept is 3.5. Do the same for the line on the right.

share 20 pounds into the ratio 2:3
share 15cm in the ratio 1:3
Step-by-step explanation:
Share 20pounds in the ratio 2:3
Total ratio=2+3=5
2/5×20=8
20-8=12
Sharing 20pounds in that ratio gives 8pounds:12pounds
Share 15cm in the ratio 1:3
Total ratio=1+4=4
¼×15=3.75
15-3.75=11.25
Sharing 15cm in that ratio gives 3.75:11.25

Sara bought a computer that was originally priced at $896. The computer was on sale for 12% off. When she bought the computer, a 7% tax was added to the sale price. How much did Sara spend on the computer?
(Round to the nearest cent)
Answer:
$843.67
Step-by-step explanation:
1. Calculate the discount that was taken off from the original price.
$896 x 12% = $107.52
2. Subtract the discount taken off from the original price. This gives you the total paid AFTER the discount was taken.
$896-$107.52= $788.48
3. Calculate the tax amount by multiplying the discount price by the tax rate.
$788.48 x 7% = $55.19
4. Add the tax amount back to the discount price.
$788.48 + $55.19 = $843.67

What is the slope of a line perpendicular to the line y = −14x – 1?
Answer:
m = ¹/₁₄Step-by-step explanation:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1
{Two lines are perpendicular if the product of theirs slopes is equal -1}
y = -14x - 1 ⇒ m₁ = -14
-14×m₂ = -1 ⇒ m₂ = ¹/₁₄
So, the slope of a line perpendicular to the line y = -14x - 1 is m = ¹/₁₄
