Answer:
A:{(7,9),(13,6),(3,9),(11,-4),(1,7)}. inverse={(9,7),(6,13)(9,3),(-4,11),(7,1)}
B:{(11,8),(5,6),(3,7),(21,2),(2,5)} inverse={(8,11),(6,5)(7,3),(2,21),(5,2)}
isoceles
Step-by-step explanation:
because isosceles triangle have 2 sides with equal measurement and a same angle can be formed 1 or 3 times not 2 times.
20
there are 10 2s
2×10 =20
A.) 13
Since DB =36, and AC is the same line, then AC = 36. The new equation is 36 = 3x - 3. Do inverse operation. Add 3 to both sides of the equation: 36+3=39 & -3+3=0. New equation is 39=3x. Finally divide. 39/3= 13.
90 degrees
A triangle equals 180
180 - 60
= 120
120 - 30
= 90
Also you can easily get the answer without doing any math because you can see the angle is a right angle
Right angles equal 90
Hope this helps dude
Hello!
We can solve this system using substitution.
Since y = -3x + 5, we can substitute this into the following equation:
5x - 4(-3x + 5) = -3
Simplify:
5x - 4(-3x) - 4(5) = -3
5x + 12x - 20 = -3
Combine like terms:
17x - 20 = -3
Add 20 to both sides:
17x = 17
x = 1
Substitute to find y:
y = -3(1) + 5
y = -3 + 5
y = 2
Solution: (1, 2)
