I forgot how to do this!!

The answer would be 6:15 since it can be divided by two and equal 3:5, i think

The vertices of a triangle are P(-2, -4), Q(2, -5), and R(-1,-8). Name the vértices of the triangle after reflecting over the x-

Serga [27]

Answer:

P(-2,4)

Q(2,5)

R(-1,8)

Step-by-step explanation:

The rule for reflecting points across the x-axis is to keep the x-value the same but "negate" the y-value. So, the points above are your answers.

Write the function f(x) = -4x2 + 24x - 42 in vertex form, and identify its vertex.

Vlad [161]

ANSWER

The vertex form is $f(x)=-4(x-3)^2-6$

EXPLANATION

We use completing squares

$f(x)=-4x^2+24x-42$

We factor -4 out of the first two terms

$f(x)=-4(x^2-6x)-42$

We add and subtract $-4(-3)^2$ , that is coming from, $(\frac{b}{2a})^2$ .

$f(x)=-4(x^2-6x)+ -4(-3)^2--4(-3)^2-42$

$f(x)=-4(x^2-6x+(-3)^2)--4(-3)^2-42$

The expression in the first parenthesis is now a perfect square.

$f(x)=-4(x-3)^2+36-42$

$f(x)=-4(x-3)^2-6$

The function is now in the form,

$f(x)=a(x-h)^2+k$ , where $V(h,k)$ is the vertex

Hence the vertex is $(3,-6)$
