There was a 20% decrease. To find the decrease, subtract the old number from the new number. (30-24=6) Then divide the decrease (6) by the original number and multiply the answer by 100. (6/30=0.2 0.2*100=20).
Answer:
y = 7/2 x -2
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-2 -5)/(0-2)
=-7/-2
= 7/2
We know the y intercept is -2 ( The x coordinate is 0)
Using the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = 7/2 x -2
Answer:
D
Step-by-step explanation:
∠ABC= ∠DBE (vert. opp. ∠s)
(6x -7)°= (4x +23)°
6x -7= 4x +23
<em>Being</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>
6x -4x= 23 +7
<em>Simplify</em><em>:</em>
2x= 30
<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>2</em><em>:</em>
x= 15
<em>Substituting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>:</em>
m∠ABC
= 6(15) -7
= 83
3 4 6 9 13 18 24 31 39 48 58
+1 +2 +3 +4 +5 +6 +7 +8 +9 +10
