Answer:

DI = 38

Step-by-step explanation:

Δ EHC and Δ DIC are similar and ratios of corresponding sides are equal, that is

$\frac{DI}{EH}$ = $\frac{DC}{EC}$ , substitute values

$\frac{DI}{76}$ = $\frac{1}{2}$ ( cross- multiply )

2DI = 76 ( divide both sides by 2 )

DI = 38

Which equation is the inverse of y=2x^2-8

shusha [124]

Step-by-step explanation:

In order to get the inverse of equation, we will interchange the variables and solve for x and y as follows.

$y = 2x^{2} - 8$

whereas, $y + 8 = 2x^{2}$

or x = $\sqrt{\frac{y+8}{2}}$

Now, on interchanging the variable we will get the equation as follows.

$x = 2y^{2} - 8$

$x + 8 = 2y^{2}$

y = $\sqrt{\frac{x+8}{2}}$

The first number of three consecutive even integers equals the sum of the second and third. Find the three numbers.

Arlecino [84]

The first integer (x) is equal to the consecutive even integers, x+2, x+4.

x = (x+2) + (x+4)

x = 2x + 6

x - 6 = 2x

x = -6 (First integer)

-4 (Second integer)

-2 (Third integer)

Integers: -6, -4, -2

Equation: x = (x+2) + (x+4)
