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
(x + 4) * (x -2)
The 2 numbers are -4 and 2
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 :)
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
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.
