Mathematics
1 answer:
stealth61 [152]3 years ago
6 0

Answer:

y = 7 - 2x/3

Step-by-step explanation:

Make the y alone, so 3y = -2x+21

Divide everything else by 3, so y = -2x/3 +7

You end with the answer of y= 7-2x+3

If cheese is $4.40 per kilogram, what should i pay for 200 grams
Contact [7]
1 kg is 1,000 grams.


200 grams are 1/5 of 1000 grams, that is 1/5 of 1 kg.

Thus 200 g= 1/5 kg = 0.2 kg.



      1 kg of cheese is <span>$4.40, 
</span>
so 0.2 kg of cheese is \displaystyle{ \frac{0.2kg \cdot \$4.40}{1kg}}=4.40 \cdot0.2 \$= 0.88\$


Answer: $0.88

Consider the following piece-wise function. Which of the below correctly describes the graph shown?
elena55 [62]

Answer:

C.

f(x)=\left\{\begin{array}{l}\dfrac{1}{2}x-3,\ \ x

Step-by-step explanation:

The graph of the piecewise function consists of two linear functions which graphs meets at point with x-coordinate x = 2.

1. The left linear function is determined for all x < 2 and is passing through the points (0,-3) and (-2,-4). So, its slope is

\dfrac{-4-(-3)}{-2-0}=\dfrac{-1}{-2}=\dfrac{1}{2}

and its equation is

y-(-3)=\dfrac{1}{2}(x-0)\\ \\y=\dfrac{1}{2}x-3

2. The right linear function is determined for all x ≥ 2 and is passing through the points (2,-2) and (3,1). So, its slope is

\dfrac{1-(-2)}{3-2}=\dfrac{3}{1}=3

and its equation is

y-1=3(x-3)\\ \\y=3x-8

3. Hence, the expression for the piece-wise function is

f(x)=\left\{\begin{array}{l}\dfrac{1}{2}x-3,\ \ x
