Y = 3x - 3. The slope here is 3. A perpendicular line will have a negative reciprocal slope. This can be found by " flipping " the slope and changing the sign......3 or 3/1...." flip " ...becomes 1/3...change the sign...becomes -1/3. So ur perpendicular line will need a slope of -1/3.
y = mx + b
slope(m) = -1/3
(-7,9)...x = -7 and y = 9
now we sub and find b, the y int
9 = -1/3(-7) + b
9 = 7/3 + b
9 - 7/3 = b
27/3 - 7/3 = b
20/3 = b
so ur perpendicular line containing the brace is : y = -1/3x + 20/3
Answer:

1.63 ÷10=.163 an ounce
Answer:
5 times greater.
Step-by-step explanation:
1.7 x 10^6 = 1700000.
3.4 x 10^5 = 340000
.
1700000 / 340000 = 5.
90 degrees because that is a 30 60 90 triangle
Answer:
<em>m<ZXY - m<WXZ = m<WXY
</em>
Step-by-step explanation:
given:
point Z is in the interior of <WXY creating XZ.
<em>if m<WXZ = 20
</em>
<em> m<WXY = 100
</em>
find:
what would equation would you set up to find the missing angle measure?
solution:
Since Z is interior of <WXY
<em>m<ZXY - m<WXZ = m<WXY
</em>
<em><WXY = 100 - 20 = 80°
</em>
therefore, the equation would be <em>m<ZXY - m<WXZ = m<WXY </em>
