Hope this helps~
Step-by-step explanation:
Look at the graph they gave you. ... At first it looks like an ugly mess.
But look closer. There are only two lines there that go through the origin,
so one of those is the answer to the question.
Now let's talk about the slope of a line.
-- If the slope of a line is positive, that means it rises as it goes.
If you walk the graph from left to right, you're climbing.
-- If the slope of a line is negative, that means it falls as it goes.
If you walk the graph from left to right, you're going down-hill.
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2 . That's positive.
The line on the graph slopes up. To walk it, you have to climb.
In the picture, that can only be line 'c' .
Answer:
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2. That's positive.
The line on the graph slopes up. To walk it, you have to climb.

brainliest. follow anything . box of chocolates contains seven milk chocolates and six dark chocolates. Five of the milk chocolates and four of the dark chocolates have peanuts inside. You randomly select a chocolate and eat it. What is the probability it is a dark chocolate with peanuts?
options=2/3, 4/13, 11/13 and 8/13
Answers
Answer: 4/13
Step-by-step explanation: There are a total of 13 chocolates, and 4 of those are dark chocolate with peanuts.
Probability that the chocolate you eat is a dark chocolate with peanuts is 4/13.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Total number of milk chocolates = 7
Total number of dark chocolates = 6
Number of milk chocolates that have peanuts inside = 5
Number of dark chocolates that have peanuts inside = 4
Total number of chocolates = 7 + 6 = 13
Probability that the randomly selected chocolate is a dark chocolate with peanuts = 4/13
Hence the required probability is 4/13.

Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)
Answers
Answer:
An exponential function in the form y=9(4ˣ)
Step-by-step explanation:
Step(i):-
Given that exponential function
y = a bˣ ...(i)
The equation (i) passes through the point (0,9)
9 = a (b )⁰ = a
a =9
Step(ii):-
The equation (i) passes through the point (3,576)
576 = 9(b)³
⇒ [tex]\frac{576}{9} = b^{3}[/tex]
⇒ 64 = b³
⇒ 4³ = b³
[tex](4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }[/tex]
b = 4
Final answer:-
An exponential function in the form y=abˣ
An exponential function in the form y=9(4ˣ)

Nikki used the calculations shown to determine whether a carton of 12 eggs or a carton of 18 eggs was the better buy.
A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39.
Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg
Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg
The 12-egg carton has the lower unit cost, so it is the better buy.
Answers
She is right, however her explanation is wrong.
In order to find the unit price, you need to divide the amount by the cost.
You will then see that 12 divided by 2.39 < 18 divided by 3.39.
The smaller unit price is obviously the better buy.

Lexi say that -68 feet is a greater depth than- 75 feet, since-68>-75. Is Lexi correct? Explain
Answers
Answer:
No
Step-by-step explanation:
When working with negative numbers in terms of depth, greater depth are depicted by values as we move farther to the left of the number line.
With this in mind, - 75 feets is farther to the left of the number line and as such represents a greater depth value Than - 68 feets
Therefore, when expressing depth or elevation distances, the values should be iewwd in absolute terms. Then |75| > |68|. While bearing in mind that depth is downward and thus negative
