Answer:
no
Step-by-step explanation:
Put 2 where x is and see if you get a true statement.
1/2(2) -4 = 5
1 -4 = 5
-3 = 5 . . . . . . False
2 is not a solution to the equation.

The solution is x=18.
Cos x=5/12. Solve for x which is 65.37 degrees.
Y = mx+b
1 = 2(1) + b
1=2+b
1-2=b
or
b=-1
equation
y = 2x - 1
answer:<span>a. y=2x-1</span>
A = bh
A = (22)(18)
A = 396 m²
A = ¹/₂h(b₁ + b₂)
A = ¹/₂(8)(16 + 12)
A = ¹/₂(8)(28)
A = ¹/₂(224)
A = 112 cm²
P = 2l + 2w
20 = 2l + 2(4)
20 = 2l + 8
- 8 - 8
12 = 2l
2 2
6 = l
C = 2πr
C = 2(3.14)(8)
C = 2(25.12)
C = 50.24 in
A = πr²
A = (3.14)(3)²
A = (3.14)(9)
A = 28.26 m²
Answer:
14
Step-by-step explanation:
4x-29+ 5x-9= 7x -10
4x+5x-29-9=7x-10
9x-38=7x-10
9x-7x=38-10
2x=28
x=28/2
x=14
