Answer:

Step-by-step explanation:

The rate of chnage is the same as the slope.

Slope is x/y. How many y increases/decreases per increase of 1 x

slope for A is

2/500 every 2 x increase, y goes up by 500.

slope for B is

2/500 every 2 x increase, y goes up by 600-100 = 500

slope for C is

1/250

slope for D is

756/3

The greatest one out of these options is D, 756/3

Apples are sold in bags of four that cost $5, or bags of six that costs $7 per bag. What is the smallest cost at which you can b

babunello [35]

STEP 1:
BAGS OF FOUR
find number of bags needed to total 74 apples

= 74 ÷ 4 apples/bag
= 18.5 bags

*must round up to 19 bags because we cannot buy a partial bag

STEP 2:
BAGS OF FOUR
calculate price of 19 bags of 4 apples per bag

= 19 bags * $5/bag
= $95 for 19 bags of 4 apples/bag

STEP 3:
BAGS OF SIX
find number of bags needed to total 74 apples

= 74 ÷ 6 apples per bag
= 12.3333 bags needed

*must round up to 13 bags because we cannot buy a partial bag

STEP 4:
BAGS OF SIX

calculate price of 13 bags of 6 apples per bag

= 13 bags * $7 per bag
= $91 for 13 bags of 6 apples/bag

ANSWER: The smallest cost to buy 74 apples is $91.

Hope this helps! :)

70% of Ms. Miller's class passed the test on the first try. Those who failed were able to retake and half of those students pass

MrRissso [65]

Answer:

85%

Step-by-step explanation:

Calculate how many students passed on their first try. 20 x 70% is 14, so 14 students passed on their first try.
6 students retook the test. Half of 6 is 3. Add 3 to the 14 students that passed earlier.
Calculate the percent with the equation 17/20 = 0.85. 0.85 = 85%.

Is the following statement correct? Explain.

Maksim231197 [3]

Answer: The answer is NO.

Step-by-step explanation: The given statement is -

If the graph of two equations are coincident lines, then that system of equations will have no solution.

We are to check whether the above statement is correct or not.

Any two equations having graphs as coincident lines are of the form -

$ax+by=c,\\\\dax+dby=dc,\\\\\textup{where}~~d\neq 1.$

If we take d = 1, then both the equations will be same.

Now, subtracting the second equation from first, we have

$a(1-d)x+b(1-d)y=c(1-d)\\\\\Rightarrow ax+by=c,~\textup{since}~d\neq 1,~\textup{so}~1-d\neq 0.$

Again, we will get the first equation, which is linear in two unknown variables. So, the system will have infinite number of solutions, which consists of the points lying on the line.

For example, see the attached figure, the graphs of following two equations is drawn and they are coincident. Also, the result is again the same straight line which has infinite number of points on it. These points makes the solution for the following system.

$2x+5y=10,\\\\6x+15y=30.$

Thus, the given statement is not correct.
