Answer:

y=-6/5x - 1

Step-by-step explanation:

Slope intercept form is y=mx+b so first lets get it into correct order by subtracting the 6x to the other side.

6x-6x+5y=-5-6x

This gives you

5y=-6x-5

Now you need to isolate the y since the 5 is being multiplied by the variable "y" we need to divide to to separate. Divide all terms by 5.

5y/5=-6/5x+(-5)/5

This gives you your final answer:

y=-6/5x - 1

Answer:

y= -6/5x +1

Step-by-step explanation:

6x + 5y=5 move variable to right and change the sign

5y =-5 -6x divide both sides by 5...

5y/5 = -5-6x/5

y= -1 -6/5x reorder terms (when yo do you need to change the sign

so the -1 becomes a positive 1.....thats using the communitive

property to reorder terms

5= -6/5x+1

A sound wave travels at 330m/s and has a wavelength of 2 m. calculate its frequency and period.

RoseWind [281]

Answer:

frequency= 165Hz

period= $\frac{1}{165}$

Step-by-step explanation:

1. To calculate the frequency using the formula:

f = v/λ

where,

f=frequency (what the question asked)

v=speed of wave (given in the question=330m/s)

λ=wavelength (given in the question=2m)

SO,

$f=\frac{330}{2}$

= 165Hz

2. To calculate the period use the formula:

since $f=\frac{1}{T}$

therefore, $T=\frac{1}{f}$

where,

f= frequency (what we solved above=165Hz)

T= period (what the question asked)

SO,

$T=\frac{1}{165}$

The scatter plot below shows the profit earned each month by a new company over the first year of operation.

raketka [301]

Explanation:

To determine the slope and y-intercept of the equation, let us plot the coordinates in the slope-intercept form.

Analyzing the graph, some of the points that are on the straight line is (1,0),(3,5), (9,20)

Let us consider the points (1,0),(3,5) to determine the slope.

$\begin{aligned}m &=\frac{5-0}{3-1} \\&=\frac{5}{2} \\&=2.5\end{aligned}$

Since, the profit is earned in thousands of dollars, m = 2.5 or m = 2500

Thus, slope = 2500

To determine the y- intercept, let us substitute any one of the coordinate from the graph.

Thus, let us substitute (1,0) in the equation $y=mx+b$ to determine the y-intercept.

$0=2500(1)+b\\$

Simplifying, we have,

$b=-2500$

Hence, the line of best fit equation is $y=2500x-2500$

Jenna buys 12 lb of meat. Some of the meat is chicken and costs $1.90/lb. The rest is beef, which costs $4.30/lb. She spends a t

Softa [21]

If the number of pounds of chicken is represented by c, then the number of the pounds of beef is 12 - c. The equation that best represent the given conditions above based on the total amount that Jenny spent is,
1.9c + 4.3(12 - c) = 34.8
The answer is letter D.

16x2 = 49 what is x?

pantera1 [17]

You start off,
16 x 2 = 32
You're looking for x so,

If of Saturday he drove 10 miles, then that’s 100%.
80 miles is 8 times as big as 10, which means we will multiply the 100% by 8.
Therefore the number of miles Ethan drove on Sunday is 800% the number of miles he drove on Saturday.
