Answer:
9x-10= 2x+4
x=2
Step-by-step explanation:
Answer:
option b i.e -2
y=2x+5 (given)
Now, when x = -2
y=2(-2)+5
= -4+5
=1
The student claims that when x is (-) ve then y is also (-) ve, which is not true when x=-2
because here x is (-) ve and y is (+) ve
Answer:
43,51, 86
Step-by-step explanation:
The sum of the angles of a triangle are 180
x+ x+8+2x = 180
Combine like terms
4x+8 = 180
Subtract 8 from each side
4x+8-8= 180-8
4x= 172
Divide each side by 4
4x/4 = 172/4
x=43
x+8 = 43+8 = 51
2x = 43*2 = 86
