<u>Answer</u>
-4x - 2
<u>Explanation</u>
To get the function needed, first calculate the slope of the graph.
slope = (change in y) / (change in x)
= (2 - -2)/(-1 - 0)
= 4/-1
= -4
Now use one of the point (-1, 2) in the graph and a general point (x,y) to find the function.
-4 = (y - 2)/(x - -1)
-4(x + 1) = y - 2
-4x - 4 = y - 2
y = -4x - 4 + 2
= -4x - 2
∴ f(x) = -4x - 2
2/3=.6 repeating
12/.6 repeating = 18
13 balls of yarn would be used to make 18 scarves.
5+3a = 3-2a
So
5a = -2
a=-2/5=-0.4
Answer:
D. 720cm squared is the answer
Answer: He did not convert the fractions into the like fraction to add.
Step-by-step explanation:
Given: The distance Jonah runs on Sunday= miles
The distance Jonah runs on Monday= miles
The total distance he ran =
Since both the fractions are not like , thus multiply 2 to the numerator and the denominator of the first fraction [to add fractions first convert them into like fractions], we get
The total distance he ran =
The right answer is "The total distance he ran ="
