diagonals of a rectangle are congruent.
Answer:
y=12x+22 is linear but not proportional
Step-by-step explanation:
This is a linear equation because it has an x and y within the expression without exponents or other complex operators. We can rearrange and simplify the equation into slope-intercept form.
This linear equation follows the form y=mx+b where m is the slope and b is the y-intercept. For this function, m=12 and b=22. This is not a proportional relationship because the function's y-intercept is something other than 0.
Celine has already knitted 0.8 meters. Her final result should be 1.2 meters.
To calculate how many meters Celine has to knit we should subtract the alreadu knitted length of scarf from the entire length. This give the equation:\
X=1.2m-0.8m
X is the unknown
X=0.4 meters
