Answer:
a and d = 32
Step-by-step explanation:
since ABC and DEF are similar m<A = m<D so you have the equation
5x + 12 = 8x
subtract 8x from both sides
5x + 12 -8x = 0
subtract 12 from both sides
5x -8x = -12
combine like terms
-3x = -12
devide by -3
x = 4
plug 4 into equation
5(4) + 12 = 8*4
20 + 12 = 32
32 = 32
Step-by-step explanation:
2/8=3/x+2
We move all terms to the left:
2/8-(3/x+2)=0
Domain of the equation: x+2)!=0
x∈R
We get rid of parentheses
-3/x-2+2/8=0
We calculate fractions
There is no solution for this equation
Answer:
B) y=2x+3
Step-by-step explanation:
2x+3 2 is the slope it goes up two over one 2/1 or 2 and +3 is where the line intersects the y axis ( -3 would mean that the line intersected at -3 )
The partitions involves dividing the line into subsegments
The coordinate of the point on the directed line segment is (0.5,-2)
<h3>How to partition the line?</h3>
The given parameters are:-
line segment = (-1, -1) to (5,-5)
Segment ratio = 1 : 3
The coordinates of the partition is calculated as:
![(x,y) = (\frac{mx_2 + nx_1}{m+ n},\frac{my_2 + ny_1}{m+ n})](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28%5Cfrac%7Bmx_2%20%2B%20nx_1%7D%7Bm%2B%20n%7D%2C%5Cfrac%7Bmy_2%20%2B%20ny_1%7D%7Bm%2B%20n%7D%29)
Substitute known values
![(x,y) = (\frac{1 *5 + 3 * -1}{1+ 3},\frac{1 *-5 + 3 * -1}{1+ 3})](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28%5Cfrac%7B1%20%2A5%20%2B%203%20%2A%20-1%7D%7B1%2B%203%7D%2C%5Cfrac%7B1%20%2A-5%20%2B%203%20%2A%20-1%7D%7B1%2B%203%7D%29)
Evaluate the products
![(x,y) = (\frac{2}{4},\frac{-8}{4})](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28%5Cfrac%7B2%7D%7B4%7D%2C%5Cfrac%7B-8%7D%7B4%7D%29)
Evaluate the quotients
![(x,y) = (0.5,-2)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%280.5%2C-2%29)
Hence, the coordinate of the partition is (x,y) = (0.5,-2)
