To get slope-intercept form we have to multiply x-1 by -4 and simplify it then
y=12+(x-1)(-4)
y=12+x*(-4)-1*(-4)
y=12-4x+4
y=-4x+16 - its the result
Answer- 9 you have to add all the numbers together then divide but the amount of numbers there are
Each meter has 100 centimeters. With just 1 meter, you can make 20 name tags with ribbons. So in order to make all of the name tags, you need 5 meters. 5 - 3.25 = 1.75. You need 1.75 more meters of ribbon to make all 100 of the name tags with ribbons.
Normally two. However, one is often extraneous.
8x - 2y = 48, y =4
8x - 2(4) = 48
8x - 8 = 48
8x = 48+8
8x = 56
x = 56/8 = 7
x = 7
