Answer:

Both of these equations are in slope-intercept form. The slope-intercept form of a linear equation is: y=mx+b

Where m is the y-intercept value.

y=-2x+5

y=-2x+20

The slope of the two equations are: m1=−2 and m2=−2

Step-by-step explanation:

Because the have the same slope it means the lines represented by these two equations are either parallel or are the same line.

The y-intercepts for the two lines are:b1 = 5 and b1=20

Jerrica is selling calendars to raise money for a community group she belongs to. A basic calendar sells for $10 and a deluxe ca

Sidana [21]

The correct answer is option B.

Let the basic calendars be = x

Let the deluxe calendars be = y

Total calendars are = 72 , so equation becomes:

$x+y=72$ .............(1)

Cost of 1 basic calendar = $10

So, cost of all basic calendars will be = 10x

Cost if 1 deluxe calendar = $15

So, cost of all deluxe calendars = 15y

As given, the number of deluxe calendars must be greater than or equal to 3 times the number of basic calendars, the equation becomes

y=3x ...............(2)

Putting the value of y from (2) in (1)

$x+y=72$

$x+3x=72$

$4x=72$

x=18

As, y=3x

y= $3\times18=54$

So we have 18 basic calendars and 54 deluxe calendars.

Cost of 18 basic calendars will be= $18\times10=180$

Cost of 54 deluxe calendars will be = $54\times15=810$

So total amount is = $990

Hence, the maximum revenue is $990.

Two consecutive odd whole numbers are selected. The difference between the reciprocals of the two numbers is 2/143. Determine th

nikklg [1K]

Answer:

11 and 13

Step-by-step explanation:

Suppose the smaller one is x. Then the difference of their reciprocals is ...

$\dfrac{1}{x}-\dfrac{1}{x+2}=\dfrac{(x+2)-(x)}{x(x+2)}=\dfrac{2}{x(x+2)}$

This tells us that x will be the smaller of the two factors of 143:

143 = 11×13

x = 11

The two numbers are 11 and 13.

The black graph is the graph of y= f(x). Choose the equation for the red graph

antiseptic1488 [7]

Answer:

$D$

Step-by-step explanation:

Notice that the red graph does not globally differ from the black graph: it would have been approximately the same one unless it had been displaced by 3 units up. Therefore, it was only the ordinate axis that underwent our change: $y - 3 = f(x) \Leftrightarrow y = f(x) + 3$ .
