Answer:

The value of k is 11.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

2=(k-3)/(5-1)

2=(k-3)/4

2*4=k-3

8=k-3

k=8+3

k=11

Every weekday after tennis practice, Will buys either a carton of milk or a bottle

Gemiola [76]

Answer:

The correct options are;

The cost of milk powder is $3 per bottle

An equivalent expression for the total cost of Will's beverages during this month is 60 - m dollars

Step-by-step explanation:

The given information are;

The items Will buys every weekday after tennis practice = A carton of milk or a bottle of powder drink

The number of milk purchased during the month = m

Will's total cost for beverages in dollars last month = 2·m + 3·(20 - m)

1) Therefore, given that the total amount is factored in dollars, we have;

2·m and 3·(20 - m) are dollar amounts, while, m is a quantity;

Therefore;

Where;

2·m = The total cost of the cartons of milk, then the factor 2 represents $2.00 which is the cost per carton of milk

Similarly, 3·(20 - m) can be said to represent the total cost of the powder drink then the factor 3 represents $3.00 which is the cost per powder drink and the factor (20 - m), represents the number of powder drink Will buys for the month

From which we found the cost of milk powder = $3.00 per bottle

2) The expression, 2·m + 3·(20 - m) simplifies to 2·m + 60 - 3·m, which gives;

2·m + 60 - 3·m = 60 - m which is an equivalent expression for the total cost of Will's beverages for the month.

Multiply. 2x(x2 + 2x - 6)

Stels [109]

2x(x2 + 2x - 6)
First add what is in the "(" wich is 2x+2x
2x(4x - 6)
Second multiply the 2x by the 4x & -6
8x-12x
Now subtract the -12x from the 8x
8x-12x = -4x

Write an equation in standard form for a line that passes through (2,2) and (0,-3).

asambeis [7]

So,

The standard form is:
y = mx + b

First, we find "m," the slope. Subtract the y-coordinates from each other. Do likewise with the x-coordinates.

2 - -3 = 5
2 - 0 = 2

Slope = 5/2

$y= \frac{5}{2} x+b$

Now, we can substitute the second solution into this equation for x and y and solve for "b."

$-3= \frac{5}{2} *0+b$

$-3= b$

Now we have our complete equation.

$y= \frac{5}{2} x-3$

In a pen with rabbits and chickens someone counted 25 heads and 80 legs a rabbit has four legs and each chicken has 2 legs, how

Komok [63]

I just kind of sat here playing with numbers i dont really know a shortcut but the answer is 10 chickens and 15 rabbits
10*2= 20 each chicken has two legs so thats 10 heads 20 legs
15*4=60 each rabbit has four legs so thats 15 heads 60 legs
15+10=25 heads
20+60=60 legs
