Answer:
45 i think i dont know
Step-by-step explanation:
m
∠
2
=
x
holds true.
Complementary angles have a sum of
90
˚
. Thus, if
∠
1
and
∠
2
are complementary,
m
∠
1
+
m
∠
2
=
90
Substitute the equivalent forms of these angle measurements
(
x
,
x
)
.
x
+
x
=
90
Solve algebraically.
2
x
=
90
x
=
45
Each angle is
45
˚
.
y-int: 140
slope: -4
to find the slope u gotta use the (y2-y1)/(x2-x1) formula
120-140 = -20
5-0 = 5
-20/5 = -4
Answer:
x = -1
Step-by-step explanation:
-1 + 3 = 2
-(-1) + 1 = 2 or 1 + 1 = 2
Answer:
457.95
Step-by-step explanation:
430 + 6.5% (27.95) = 457.95
Answer:
(-3;6]
Step-by-step explanation:
-9<4x+3≤27 |-3 (because we have to remove everything what's next to the x)
-9-3<4x+3-3≤27-3
-12<4x≤24 |:4
-12:4<4x:4≤24:4
-3<x≤6
x = (-3;6]
