Answer:
slope = 1
y-intercept = 5
Step-by-step explanation:
change in y-values = 1
change in x-values = 1
slope = 1/1 or 1
to find the y-intercept ('b'), select an ordered pair: (1, 6)
use the slope-intercept formula and solve for 'b':
6 = 1(1) + b
6 = 1 + b
5 = b
slope = 1
y-intercept = 5
Answer:
w = 36
Step-by-step explanation:
You can make a ratio 98 : 84 = 42 : w
49w = 1764
w = 36
2(5*10)+2(10*4)+2(5*4)=
2(50)+2(40)+2(20)=100+80+40=
220 cm^2
I found the answer by finding the areas of the 3 different sides, multiplying each area by 2 since each side has another side that is equal on a rectangular prism, then adding all of them together.
