Answer:
2x-10
Step-by-step explanation:
2(x) - 2(5) = 2x - 10
Answer:
C
Step-by-step explanation:
-2x + 7= 3x -8
+8
-2x + 15=3x
+2x
15=5x
divide
x=3
put 3 in one of the equations
y= 3(3) - 8
y=9-8 = y=1
answer is c

Answer:
Letter 'S'
Step-by-step explanation:
in the word 'MATHEATICS' has no line symmetry.
Answer:
1) -7/4
2) 4/7
3) -1/5
Step-by-step explanation:
1) A parallel line would have the same gradient so:
4y = -7x +3
y =
So a parallel line would have the gradient of
.
2) A perpendicular line would have the inverse reciprocal of the gradient so multiplying the 2 gradients would equal -1 so:
Initially Gradient = -7/4
-7/4 x Perpendicular line = -1
Perpendicular line = -1 x 4/-7
Perpendicular line = 4/7
3) Using the same principle, the perpendicular gradient would be -1/5x
