Equation: -1/2x + 1 = -x + 8
Work:
-x/2 + 1 = -x + 8
1 - x/2 = -x + 8
1 - x/2 = 8 - x
2 - x = 16 - 2x
-x = 16 - 2x - 2
-x = 2x + 14
-x + 2x = 14
x = 14
Final Answer:
x = 14
Answer:
8624.03
Step-by-step explanation:
Answer:
The coordinates of image are : (-3,4) , (-8,2) and (-4,7)
Step-by-step explanation:
The rule is given as (x, y) —> (-x,y)
The coordinates of the triangle are : (3,4) , (8,2) and (4,7)
The coordinates of the image of the triangle will be : (-3,4) , (-8,2) and (-4,7)
Graphing the coordinates of image and connect the points to get the image of the triangle as attached below;
You will notice the rule of the transformation is a reflection along the y-axis.
Answer:
x = 3
y = 0
z = 8
Step-by-step explanation:
a) 3x + 3y - z = 1
b) z = 8
c) -x -3y + 2z = 13
a) 3x + 3y - 8 = 1 (substitution)
a) 3x + 3y = 9
c) - x - 3y + 2(8) = 13 (substitution)
c) -x - 3y + 16 = 13
c) -x - 3y = -3
(3x + 3y = 9) + (-x -3y = -3)
= 2x = 6
x = 3
a) 3(3) + 3y - 8 = 1
9 + 3y - 8 = 1
y = (1 -9 + 8)/3
y = 0
Answer:
1) 34°
2)90°
