Answer:
36
Step-by-step explanation:
Let's solve your system by substitution.
y
=
3
x
+
5
;
y
=
x
+
19
Step: Solve
y
=
3
x
+
5
for y:
y
=
3
x
+
5
Step: Substitute
3
x
+
5
for
y
in
y
=
x
+
19
:
y
=
x
+
19
3
x
+
5
=
x
+
19
3
x
+
5
+
−
x
=
x
+
19
+
−
x
(Add -x to both sides)
2
x
+
5
=
19
2
x
+
5
+
−
5
=
19
+
−
5
(Add -5 to both sides)
2
x
=
14
2
x
2
=
14
2
(Divide both sides by 2)
x
=
7
Step: Substitute
7
for
x
in
y
=
3
x
+
5
:
y
=
3
x
+
5
y
=
(
3
)
(
7
)
+
5
y
=
26
(Simplify both sides of the equation)
Answer:
x
=
7
and
y
=
26
Answer:
Option A -The height of the building is 105 ft
Step-by-step explanation:
to get the height of the building, we calculate using SOH CAH TOA
TOA = OPPOSITE / ADJACENT
Tan 59° = h / 63
Height = tan 59° X (63)
Height = 1.6643 X 63
Height = 104.85
Height = 105 ft
X+4=-4
3x-8=-8
Hope it helps.
No because one of the X’s has multiple Y’s
