Answer:

infinitely many solutions

Step-by-step explanation:

The system of equations :

3x + 2y = 7
-4.5x - 3y = -10.5

Multiplying Equation 1 times 3 and Equation 2 times 2 :

9x + 6y = 21
-9x - 6y = -21

Putting the equations in standard form after simplifying :

6y = -9x + 21 ⇒ y = -1.5x + 3.5
-6y = 9x - 21 ⇒ y = -1.5x + 3.5

As both equations are the same, the system will have infinitely many solutions.

Write an informal proof to show triangles ABC and DEF are similar. Please don’t answer if you don’t know!!

Mila [183]

Answer:

ΔABC ~ ΔDEF

Step-by-step explanation:

If the given triangles ΔABC and ΔDEF are similar,

Their corresponding sides will be proportional.

$\frac{\text{AB}}{\text{DE}}=\frac{\text{BC}}{\text{EF}}=\frac{\text{AC}}{\text{DF}}$

By substituting the measures of the given sides,

$\frac{4}{2}=\frac{6}{3}=\frac{2}{1}$

2 = 2 = 2

Since, corresponding sides of both the triangles are proportional, both the triangles will be similar.

ΔABC ~ ΔDEF

3m - (m^2 + n); if m = 2 and n 19

deff fn [24]

Answer:

- ( 17 )

Step-by-step explanation:

m = 2

n = 19

m^2

= 2^2

= 2 x 2

= 4

= 3 x 2

= 6

3m - ( m^2 + n )

= 3m - ( m^2 + n )

= 6 - ( 4 + 19 )

= 6 - 23

= - ( 17 )

Answer: 7

Step-by-step explanation:

By the angle bisector theorem,

$\frac{21}{14}=\frac{3x-12}{6}\\21(6)=14(3x-12)\\126=14(3x-12)\\9=3x-12\\21=3x\\x=\boxed{7}$
