Answer:

No it cannot

Step-by-step explanation:

the sum of the angles of the triangles has to be 180 so if you have two right angles then the last angle has to be 0 which is not possible

Help!!!!!!!!!!!!!!!!!!!!!!!!!!

Marta_Voda [28]

Answer:

x > - 8 or x < 2

Step-by-step explanation:

Given

- 8 < 2(x + 4) or - 3x + 4 > x - 4

Solve each part separately

- 8 < 2(x + 4) ← divide both sides by 2

- 4 < x + 4 ( subtract 4 from both sides )

- 8 < x , thus

x > - 8

- 3x + 4 > x - 4 ( subtract x from both sides )

- 4x + 4 > - 4 ( subtract 4 from both sides )

- 4x > - 8

Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity

x < 2

Solution is x > - 8 or x < 2

Find the value of y, given value of x

baherus [9]

Answer:

a. y = 2+4.3x when x = -6

substituting value of x, we get

y=2+4.3*-6=2-25.8=23.8

b. y = (x-3)² when x = 9

substituting value of x, we get

y=(9-3)²=6²=36

c. y=x-2 when x = 3.5

substituting value of x, we get

y=3.5-2=1.2

d. y=5x-4 when x = - 2

substituting value of x, we get

y=5*-2-4=-10-4=-14
