Find the value of x that makes the two triangles equal

Leona [35]

Answer:

Step-by-step explanation:

$\triangle CDE \sim\triangle FGH...(given)$

$\therefore \frac{CD}{FG}=\frac{CE}{FH}...(csst)$

$\therefore \frac{4x}{28}=\frac{25}{35}$

$\therefore \frac{x}{7}=\frac{5}{7}$

$\therefore x=\frac{7\times 5}{7}$

$\therefore x=5$

Find the solution to the following system using substitution or elimination: y = 3x + 2 y = -2x - 8 O A. (-5,-) OB. (-2,-4) O C.

mr Goodwill [35]

Answer:

B. (-2,-4)

Explanation

Given equations:

y = 3x + 2

y = -2x - 8

Solving both equations will yield the values of x and y;

Solution:

y = 3x + 2 ----- (i)

y = -2x - 8 ------ (ii)

Using substitution method, input equation i, into ii

3x + 2 = -2x - 8

Collect like terms and solve;

3x + 2x = -8 -2

5x = -10

x = -2

Then put x = -2 into i, to find y

y = (-2 x 3) + 2

y = -6 + 2 = -4

So, the solution of the equation is B. (-2,-4)

In the equation x=y^3 - 10, is y a function of x?

natali 33 [55]

Answer:

Step-by-step explanation:

If y is a function of x, then the equation would be written as a "y =" equation, not an "x = " equation. This example is one where x is a function of y.
