Answer:

Corresponding sides can be changed, yet they still have to be proportional. If they are congruent, then the triangles will be congruent.

The angles always have to be congruent however, or else the whole shape of the triangle will be changed and the triangle will not be similar.

Answer:

$\large\boxed{\large\boxed{10/21}}$

Explanation:

There are only two mutually exclusive possibilities for each complex electronic system: being defective or being not defective:

Number of complex electronic systems: 7
Nmber of defective systems: 2
Number of not defective systems: 5

Probability that no defective systems are found in the sample is the equal to the probability of selecting them consecutively without replacement and finding each one is not defective:

Porbability the first is not defective × probability the second is not defective

5/7 × 4/6 = 20/42 = 10/21

Substitution method...need help.. started but cant finish

trapecia [35]

Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.

-5x + y = 13 ⇒ y = 5x + 13

Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :

-3x + 3y = 3 ⇒ -3x + 3 (5x + 13) = 3

Simplify and solve for x :

-3x + 15x + 39 = 3

12x = -36

x = -3

Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give

-3 (-3) + 3y = 3

9 + 3y = 3

3y = -6

y = -2

So the solution to the system of equations is (x, y) = (-3, -2).
