Write an equation of a line in slope-intercept form with the given slope and y-intercept.

Nostrana [21]

Answer:

y = -6x - 2

y = x - 12

Step-by-step explanation:

Slope-intercept equation for line of slope m and y-intercept b:

y = mx + b

A. m = -6, b = -2

y = -6x - 2

B. m = 1, b = -12

y = x - 12

Select the correct answer. A dormitory manager buys 38 bed sheets and 61 towels for $791.50. The manager get another 54 bed shee

svetlana [45]

Okay, let's represent the price of a bed sheet with 'b' and a towel with 't':

54b + 50t = 923

38b + 61t = 791.50

Now, if we subtract both sides by 54b (on the first equation), we get this:

50t = 923 - 54b

Divide both sides by 50:

t = 18.46 - 1.08b

Now that we know this, we can move on to the 2nd equation:

38b + 61t = 791.50

Input the variable 't':

38b + 61(18.46 - 1.08b) = 791.5

38b + 1126.06 - 65.88b = 791.5

38b - 65.88b = 791.5 - 1126.06

Simplify:

-27.88b = -334.56

Because both sides are negative, we can turn it into a positive:

27.88b = 334.56

b = 334.56/27.88

b = 12

Now that we know that b = 12, we can easily input it into any equation:

648 + 50t = 923

50t = 275

t = 5.5

One bed sheet costs $12 and one towel costs $5.50

Option C is the answer.

the price of milk in 2013 was around $3.28 a gallon. This was eight times as much as you would have probably paid for a gallon o

Jlenok [28]

The cost of the milk is $\fbox{\$\,0.41{\text{ a gallon}}}$ in 1950s.

Further explanation:

The price of milk in 2013 was around $\$3.28$ a gallon.

And it is given that this was eight times as much as one can would have probably paid for a gallon of milk in the 1950s.

It is given that the price of milk in 2013 is $\$3.28$ a gallon.

Assume the price of milk in 1950 be $\$x$ a gallon.

Now, given that 8 times of $x$ is the price of milk in 2013.

Therefore, $8x$ is the price of milk in 2013 and also $\$3.28$ is the price of milk in 2013.

Equating $8x$ and $\$3.28$ equal as both are the price of milk in 2013 as,

$\begin{aligned}8x&=3.28\\x&=\frac{{3.28}}{8}\\x&=0.41\\\end{aligned}$

Here, x is the price of milk in 1950.

Therefore, the cost of the milk is $\fbox{\$\,0.41{\text{ a gallon}}}$ in 1950s.
