I need help on this question can anyone explain to me the answer?
raketka [301]

Answer:

Option C, y = \frac{1}{10} x+1

Step-by-step explanation:

We can find the correct answer by plugging in the x and y values of a point on the graph into each option, then finding the one that gives a true statement as a result.

For example, one point on the graph is (30,4). We can substitute 30 for the x and 4 for the y in option C's equation, y = \frac{1}{10} x+1. Then, simplify:

y = \frac{1}{10} x+1\\4 =\frac{1}{10} (30)+1\\4 = \frac{30}{10} +1\\4 = 3 +1\\4 = 4

4 does equal 4, so when we substitute a point from the graph into this equation, the result is a true statement. Thus, option C is the answer.

The length of the rectangle is twice the width. Find the length of the rectangle if the perimeter is 42m.
kompoz [17]

Answer:

28m

Step-by-step explanation:

2x+x=42

3x=42

x=14

However, since the length of the rectangle is twice the width, we'll need to multiply it by 2.

So: 14 times 2=28
