Hope this helps! Because when you would fill in the variables 0=0 which which make the expression too that they’d equal the same.

What are the slope and the y-intercept of the linear function that is represented by the table?

mafiozo [28]

Answer:

slope is -2 and the y-intercept is 12

Step-by-step explanation:

a key thing to remember: x is always equal to 0 when finding the y-intercept.

so if you look at the table for where 0 is, you get the point (0,12) meaning the y-intercept is 12.

to find the slope use the equation: slope= change in y/change in x

you can use any two points to find this.

lets take the points of the x-intercept (6,0) and the y-intercept (0,12)

12-0/0-6

12/-6

-2 = slope

Write 12 ten thousands, 8 thousands,14 hundreds, 7 ones in standard form

Cloud [144]

The correct answer is: 
129,407.

Explanation: 
12 ten-thousands = 12*10000=120,000.
8 thousands = 8*1000=8000;
this gives us 120,000+8,000=128,000.

14 hundreds = 14*100=1400;
this gives us 128,000+1,400=129,400.

7 ones = 7*1=7;
this gives us 129,400+7=129,407.
