At a hockey game, a vendor sold a combined total of 148 sodas and hot dogs. The number of sodas sold was three times the number
AleksandrR [38]

Answer:

37 hot dogs and 111 sodas

Step-by-step explanation:

148 divided by 4= 37

148 - 37= 111

if the number of sodas was three times it would have to be broken up into three groups making the hot dogs 37 and sodas three times the amout would be 111. hope this helped sorry for any spelling mistakes

katrin [286]
A = s^2
A' = 2s*s'

When the area is 36 cm^2, the side (s) is 6 cm. The area is increasing at the rate
A' = 2(6 cm)*(6 cm/s) = 72 cm^2/s

-5x+2y=6<br> -x+2y=-2 <br> what is the solution to the system of equations?
dybincka [34]

Step-by-step explanation:

- 5x + 2y = 6 \\ - x + 2y =  - 2 \\  \\  - 5x + 2y - ( - x + 2y) = 6 - ( - 2) \\  - 5x + 2y + x - 2y = 6 + 2 \\  - 4x = 8 \\  \frac{ - 4x}{ - 4}  =  \frac{8}{ - 4 }  \\ x =  (- 2) \\  \\  -5x + 2y =  6 \\  - 5 \times  - 2 + 2y = 6 \\ 10 + 2y = 6 \\ 2y = 6 - 10 \\ 2y =  - 4 \\  \frac{2y}{2}  =  \frac{ - 4}{2}  \\ y =  - 2 \\  now \: lets \: see \: whether \\ this \: equation \: is \: correct. \\  - x + 2y = -  2 \\ -   ( - 2) + 2 \times  - 2 = -  2 \\ 2 + 2  \times   - 2 =  - 2 \\ 2 - 4 =  - 2 \\  - 2 =  - 2 \\ yes \: this \: equation \: is \\ correct.

The equations of two functions are y=-21x+9 and y=24x+8 which function is changing more quickly? Explain
antoniya [11.8K]

Given:

The equations are

y=-21x+9

y=24x+8

To find:

Which function is changing more quickly.

Solution:

The slope intercept form of a line is

y=mx+b

Where m is slope and b is y-intercept.

On comparing y=-21x+9 with the slope intercept form, we get

m_1=-21

|m_1|=|-21|

|m_1|=21

On comparing y=24x+8 with the slope intercept form, we get

m_2=24

|m_2|=24

Since, |m_1|, it means the absolute rate of change of second function is greater than the first function.

Therefore, the second function is changing more quickly.
