The equation for the function is
Explanation:
The equation for the function that passes through the points and
The equation of the line that passes through the points and is given by
where m is the slope and it can be determined using the formula,
Substituting the values of x and y in the slope formula, we have,
Simplifying, we get,
Thus, the slope is m=1.
Substituting the values in the equation , we have,
Multiplying the terms within the bracket,
Adding on both sides of the equation,
Thus, the equation for the function is
The graph of the function is missing and so i have attached it alongside the options.
Answer:
B & C are correct.
Step-by-step explanation:
From the attached graph, we can see that at interval 2, the line is falling down and not rising.
This means that the function is decreasing because y is decreasing while x is increasing.
Also, when both x and y are increasing, the slope is positive but when one is increasing and the other is decreasing like we have here, it means the slope is negative.
Thus, the function is decreasing and the slope is negative.
Answer:
116
Step-by-step explanation:
82 brownies sold for $1 each is $82 in total
140-82=58
each cookie is sold at $0.5 so we need to multiply the rest of the cash by 2
58×2=116
so he needs to sell 116 more cookies to reach his goal
Answer:
17+75=?
Step-by-step explanation:
Answer:
Look at the relationship.
2.7 is 30 times larger than 0.09 (2.7 / 0.09 = 30)
So the ratio is 0.09:2.7 = 1 :30
