(-2, 0) and (0, -2)
slope = (0+2)/(-2 - 0) = -1
b = -2
slope intercept equation
y = -x - 2
compare equation from given
y - 3 = -(x + 5)
y - 3 = -x - 5
y = -x - 5 + 3
y = -x - 2 (matched slope intercept equation)
answer is A
y - 3 = -(x + 5)
Answer:
x = 10
Step-by-step explanation:
2x/3 + 1 = 7x/15 + 3
<em><u>(times everything in the equation by 3 to get rid of the first fraction)</u></em>
2x + 3 = 21x/15 + 9
<em><u>(times everything in the equation by 15 to get rid of the second fraction)</u></em>
30x+ 45 = 21x + 135
<em><u>(subtract 21x from 30x; subtract 45 from 135)</u></em>
9x = 90
<em><u>(divide 90 by 9)</u></em>
x = 10
<h2>
Another solution:</h2>
2x/3 + 1 = 7x/15 + 3
<u><em>(find the LCM of 3 and 15 = 15)</em></u>
<u><em>(multiply everything in the equation by 15, then simplify)</em></u>
10x + 15 = 7x + 45
<u><em>(subtract 7x from 10x; subtract 15 from 45)</em></u>
3x = 30
<em><u>(divide 30 by 3)</u></em>
x = 10
× equals negative 4 i think and y equals -3
Answer:
$180
Step-by-step explanation:
To find the new cost, multiply the original cost by 1.2
150(1.2)
= 180
So, the new cost of the bicycle is $180
