Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept, or the y value when x = 0 ---> (0, y)]
To find the equation's y-intercepts, you can rearrange the variables, and isolate/get y by itself
#1
cx + ay = b Subtract cx on both sides
ay = b - cx Divide a on both sides
(0,
) is your answer
Do the same for the rest, and you should get:
#2 (0, )
#3 (0, )
#4 (0, )
Answer:
Step-by-step explanation:
1)
Area) = area of square + area of triangle
square = 6*6 = 36
area of equilateral triangle = ( / 4) *a^2 = 31.1759
total area = 36 + 31.1759 = 67.1769
Perimeter) 6*5 = 30 "
2)
Area) = upper triangle + lower square
6* *sin(45) = 6 cm ( each side is 6)
upper triangle = 1/2*6*6 = 18
lower square = 6*6=36
total area = 38 + 18 = 56
perimeter = 4*6+6* = 32.4852 cm
3)
Area) = left triangle + right rectangle
left triangle = 1/2*3*4 = 6 ( this is the famous 3,4,5 triangle )
rectangle = 8*3 = 24
total area = 24+6=30
perimeter = 8+5+3+8+3= 27'
