Answer:
y=4x+7
Step-by-step
(-2,1) and (1,-11)
1)Rule you should use is run over rise aka slope
y²-y^1=
x^2-x^1=
(-11)-1=12
1-(-2)=3
12/3=4
slope =4
2)Rule of point slope intercept
y - y1 = m(x - x1)
y+1=4(x+2)
y+1=4x+8
-1 -1
y=4x+7
You need to add 1 3/4, 2 1/3, and 2 3/4.
But before you do that you need to make them decimals.
Add 1.75, 2.33, and 2.75
Equals 6.83
Then subtract it by 20.00
Equals 13.17
Then you make that a decimal
13 17/100
Answer:
59.67 rounds to 60, 11.1 rounds to 10, so 60 divided y 10 equals 6

Answer:
Step-by-step explanation:
For the 72-deg angle, 6 is the adjacent leg. x is the hypotenuse. The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.
1) Angle T = 72°
Angle U = 54°
2) Angle M = 76°
Angle N = 76°
<em>Explanation</em><em>:</em><em> </em>
<em> </em> 1. Isosceles triangle (since 2 sides are equal)
Angle U = Angle S = 54° (equal sides of a traingle have equal angles)
angle U + angle S + angle T =180 (Angle sum Property)
54° + 54° + angle T = 180°
108 + angle T = 180°
Angle T = 180 - 108
= 72°
2. Isosceles triangle again (same properties)
angle L + angle M + angle N = 180
28 + angle M + angle N = 180
angle M + angle N = 180 - 28
angle M + angle N = 152
"angle M and N will be equal since it is
isosceles triangle"
so, 2x (M&N) = 152
x = 152 ÷ 2
= 76
therefore angle M = angle N = 76°
