I need a check so just want some help​

Mathematics
1 answer:
bazaltina [42]2 years ago
8 0

Answer and Step-by-step explanation:

We are told that AB is equal to 3x + 1.

BC is then half of AB, or \frac{3x+1}{2}.

AC is then 4 less than BC, or (\frac{3x+1}{2} ) -  4

To find the perimeter, we add all of these together.

3x + 3x/2 + 3x/2 = 6x

1 + 1/2 + (1/2 - 4) = -2

The final answer is 6x - 2.

Solve the system of equations for x and y.<br> y = x + 5<br> y = 2x + 2
DIA [1.3K]
Answer (x,y) (3, -2)

Explanation:
using the
substitution method
y
=
x
−
5
→
(
1
)
y
=
−
2
x
+
4
→
(
2
)
since both equations are expressed in terms of x we

can equate them
⇒
x
−
5
=
−
2
x
+
4
add 2x to both sides
2
x
+
x
−
5
=
−
2
x
+
2
x
+
4
⇒
3
x
−
5
=
4
add 5 from both sides
3
x
+
5
−
5
=
4
+
5
⇒
3
x
=
9
divide both sides by 3
3
x
3
=
9
3
⇒
x
=
3
substitute this value in
(
1
)
y
=
3
−
5
=
−
2
As a check
substitute these values into
(
2
)
right
=
−
6
+
4
=
−
2
=
