Answer:
answer D
Step-by-step explanation:
A and C have to be equal
B and D have to be equal
A+B+C+D have to equal 360
so, two equations
5y-3=x+3y
4x+5y-3+x+3y=360
4x=156
x=39
5y-3=9+3y
2y=42
y=21
Hope this helps plz hit the crown :D
A vertical line has an undefined slope... AKA has no slope. So your answer would be D
Answer:
D.) 28.26x²
Step-by-step explanation:
Diameter (d) = 6x
radius (r) = d/ 2 = 6x / 2 = 3x
area of circle
= π r²
= 3.14 * (3x) ²
= 28.26x²
So triangle has 3 sides
represent them as x,y,z
so lets say x=shortest side
y=2nd side
z=longest side
x is 1/2 of the second side
x=1/2(y)
shortest side is 1/3 of the longset side
x=1/3(z)
how does the triangle compart the longest side (z)
x+y+z=perimiter
solve to subsitute and convert all values to z
x=1/2y
2x=y
2(1/3z)=y
2/3(z)=y
and x=1/3(z)
therefor, subsitute so that there are only z terms
1/3(z)+2/3(z)+z=perimiter
add like terms
3/3(z)+z=p
z+z=p
2z=p
the peimiter is 2 times of the longest side
An equation that goes through (-2, 1) and has a slope of 4 is y = 4x + 9.
You can find this by looking for the y-intercept (b) by using the slope (m), the point and slope intercept form. The work is below for you.
y = mx + b
1 = 4(-2) + b
1 = -8 + b
9 = b
Now we can use that and the slope to create the equation y = 4x + 9
