The answer is 10.

Parallel lines show similar triangles showing us that (2x + 6)/10 = (x+6)/8. Solving this equation for x gives us x = 2. Plugging this into 2x + 6 gives us 2(2) + 6 = 10.

The vertex of this parabola is at (-5, -2). When the x-value is -4, the y-value is 2. What is the coefficient of the squared exp

VARVARA [1.3K]

V(-5;-2)
$f(x)=a(x+5)^2-2$

$x=-4$ . $y=2$

$2=a(-4+5)^2-2$
$2=a*1-2$
$2=a-2$
$a=4$

The answer: B

What is the range of the function y = StartRoot x + 5 EndRoot?

telo118 [61]

Answer:

y greater-than-or-equal-to 0

Step-by-step explanation:

we know that

The domain of a function is the set of all possible values of x

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

we have

$y=\sqrt{x+5}$

Remember that the radicand of the function must be greater than or equal to zero

$x+5\geq 0$

solve for x

$x\geq -5$

The domain is the interval ----> [-5,∞)

For x=-5

$y=\sqrt{-5+5}=0$

The range is the interval ----> [0,∞)

$y\geq 0$

Suppose that x and y very inversely. X equals -4/15 when y =-105. Write a function that models the inverse variation then find Y

dezoksy [38]

Xy = k
(-4/15)(-105) = k
28 = k
xy = 28
10y = 28
Divide both sides by 10
y = 2.8
