Answer:

the correct answer is

lets say the number xy (x in tens place and y in units place)

first equation (x+y =10 i.e x=10-y

also 3x-2y=15 i.e 2y=3x-15)

second equation

substitution the value of x from first equation in second equation (or you can do vice- versa)gives you 2y=3(10-y)-15 and so,

2y=30-3y-15 i.e5y=15 and y=3

since x=10-y; x=10-3 which is 7

the answer is 73.

Step-by-step explanation:

Gabby is an aspiring country artist. She has a record contract that pays her a base rate of $200 a month and an additional $12 f
Rus_ich [418]

Answer:

From the formula above, you see that your slope would be the $12.

Step-by-step explanation:

So, from this problem the base rate is the y-intercept because it is fixed. The slope of the is the additional fee because it's changing by the number of albums sold. Below is the equation that should have been created using the slope intercept formula.

220 + 12x = 644

You will need the slope intercept form, y = mx + b  

m is the slope

b is the y-intercept
