Answer:
x=21
y=45
z=101
Step-by-step explanation:
Angles crossing each other are congruent
86=4x+2
84=4x
x=21
Quadrilateral has 360 degrees
86 + 86 + 2y+4 + z-7 = 360
172 + 2y+4 + z-7 = 360
2y+4=94
2y=90
y=45
z-7=94
z=101

Answer:
You CAN do it. triangle with the circle. find area of triangle first and subtract circle. (8*8)/2 = 32. minus circle. (2.5*pi^2) = 24.674011. so we have 32 - 24.7 (rounded) = 7.3 for triangle. as for the other? divide it into segments. we have a rectangle on bottom followed by 2 triangles on top of that rectangle. Recangle height is 2 * width. The width is 8 as we can see the top. 2*8= 16. plus the triangles. we know the triangle height is 6 minus the 2 from the rectangle height so 6-2=4 times the width which is the rectangle width minus the 6 from the middle divided by 2 because there are 2 triangles. 8-6=2/2 = 1. height * width = 4 divide by 2 = 2. that is the area of one triangle. but because there are 2 triangles multiply by 2. 2*2 = 4. 16+4=20 for the area of the second figure.

Answer below!
Step-by-step explanation:
since y = -3x + 1, you can just plug those numbers in on the first equation.
6x + 2(-3x+1) = 2 (see how I replaced y into -3x + 1)
then distribute 2.
6x - 6x + 2 = 2, subtract 2 to both sides
6x - 6x = 0, combine x
0 = 0 (this means it has an infinite amount of solutions)
The function is decreasing from x=0 to x=2
