Answer:

X= - 1

Step-by-step explanation:

7−4x=2−9x

7+−4x=2+−9x

−4x+7=−9x+2

Step 2: −4x+7+9x=−9x+2+9x

5x+7=2

Step 3: 5x+7−7=2−7

5x=−5

Step 4: 5x

5

= −5

Ruth found 37 tickets for $7. Please help Ruth by figuring out the ratio. (round to 2 decimal places)
Amanda [17]

Answer:

Ratio of ticket to its price is 1  :  0.189.

Step-by-step explanation:

Here, the cost of 37 tickets = $7

Let us find the unit cost of the ticket.

\textrm{Unit Price }  = \frac{\textrm{Total Price of n units}}{\textrm{n}}

\implies U = \frac{7}{37}=0.189

So, the unit price of each ticket = $0.189

Now, ratio of Each Ticket: Unit Price = 1 : 0.189

Hence, the ratio of ticket to its price is 1  :  0.189.

Please help, I need an explanation on how to do this type of problems. I've been at this assignment for the whole day and I'm ne
laila [671]

Answer:

See image

Step-by-step explanation:

To graph the inequality

-2x + y >= -10

Change it to y = mx + b form, use a solid line (bc of the "or equal to" underline)

y >= 2x - 10 We have y-intercept at -10 and slope 2/1, shading goes above the line.

The other graph is an absolute value graph; it has a v-shape. The 7 makes it stretched 7 times taller (and skinnier) the -4 by the x shifts the whole graph to the right 4 units. The -4 at the end of the equation shifts the whole graph down 4 units. See image. The shading goes above the V (kind of looks like inside)

The solution to the system is where the shading of the two overlap. It is mostly the shading for the absolute value graph except for a tiny triangle at the bottom. See image.
