For transaction 3 it should be -155.15 and for transaction 4 it would be -223.75
Answer:
Step-by-step explanation:
Because of the right angle (90 deg) in red, and the horizontal line on the bottom axis,
we know that :
49 + (1+5x) = 90
solving for x delivers x=8
Plug in (-1, 3) into both equations
Ax - 2y = 4
A(-1) - 2(3) = 4
-A - 6 = 4 Add 6 on both sides
-A = 10 Divide -1 on both sides
A = -10
5x + By = -1
5(-1) + B(3) = -1
-5 + 3B = -1 Add 5 on both sides
3B = 4 Divide 3 on both side
B = 
True. A triangle will always have three sides, and a pentagon will always have five.
Answer:
-8
Step-by-step explanation:
well since the equation has the <em>same base</em> of 11, you can just solve for x as you normally would. so the question becomes:
4x+1 = 3x -7
<em>subtract one from both sides</em>
4x = 3x - 8
<em>subtract 3x from both sides</em>
x = - 8
