Answer:
y=50
Step-by-step explanation:
Since the y value doesn't change and it is a line
Since, the slope intercept form of a line is,
y = mx + c,
Where, m is the slope of the line.
Also, the equation of a line passes through and is,
Thus, the equation of the line passes through (-25, 50) and (25, 50) is,
Which is the required equation.
8/9
1 blue, 2 yellow, 7 red, 6 green, and 2 purple marbles = 18 marbles
The number that are not yellow = total - yellow
P( not yellow) = number that are not yellow / total
= (18-2) / 18
= 16/18
=8/9
x = 6
y = 24
z = there is no z?
All angles of a polygon add up to 360 degrees
The 2 parellel lines on top and bottom mean that there are 2 right angles on the left side
3y + 18 = 90
3y = 72
15x + 30 + 10x = 180
25x = 150
Total surface area
=2 ×(area of triangle) +( area of rectangle 1) + (area of rectangle 2) + (area of rectangle 3)
2×(1/2 × 16 ×12) + (10×12)+(16×10)+(20×10)
=672 cm²
