Answer:
<h2>b = 60</h2>
Step-by-step explanation:
We know: The sum of measures of angles in a triangle is equal to 180°.
Therefore we have the equation:
b° + 80° + 40° = 180° <em>combine like terms</em>
b° + 120° = 180° <em>subtract 120° from both sides</em>
b° + 120° - 120° = 180° - 120°
b° = 60°
Answer: X=-5
Step-by-step explanation:
............
they are the same
$6.60 i think, i subtracted the total ($14.40) with the cost of the beads ($7.80) and came to the remaining cost of $6.60 to be spent
Y = 1/2x + 5...slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular slope is -2/1 or just -2 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2
y int (b) = -2
so ur equation is : y = -2x - 2
