Usimov [2.4K]
A) x + y = 2
B) x * y = -8
B) y = -8 / x  we can substitute this into equation A
A) x + -8 /x = 2 multiplying both sides by "x"
A) x² -8 = 2x
x² +2x -8 = 0

I will give lots of points please help
marin [14]

Step-by-step explanation:

PART 1:

on the graph you can make a triangle at any point and with any angle measures.

i recommend a smaller right triangle to be easiest.

i recommend the points (0,3) A (3,0) B and (0,0) C

∆ABC angle measurements:

m∠CAB=45°

m∠ABC=45°

m∠ACB=90°

PART 2:

(4,3) D (7,0) E and (4,0) F make an identical right triangle moved 4 squares to the right

m∠FDE=45°

m∠DEF=45°

to find the missing value of the angle EFD we will use subtraction and addition

180-(45+45)

180-90

90

therefore, the m∠EFD=90°

PART 3:

both the angle measures and the shapes of the triangles are the same

PART 4:

i used a 1:1 ratio

sorry for the wait :)

Are the graphs of 4x-6y=-24 and y=2/3x+4 parallel perpendicular or neither?
ANTONII [103]

Answer:

neither

Step-by-step explanation:

4x - 6y = -24                                           y = 2/3x + 4

-6y = -4x - 24

-6/-6y = -4/-6x -24/-6                              y =2/3x + 4

  y  = 2/3x +4

Same line

Solve please:<br><br> 1/5 (25-5a) = 4-a
Liono4ka [1.6K]

Answer: There is no solution.

Step-by-step explanation:

1.) 1 / 5 (25) + 1 / 5 (-5a) = 4 - a

2.) 5 - a = 4 - a

3.) 5 - a + a = 4 - a + a

4.) 5 = 4

The variable a is completely removed, leaving the final answer as 5 = 4, which isn't true.
