Answer:

X = 1/2

Step-by-step explanation:

The question seems like (6*4x² = 3*4x)

This is a simple algebraic equation

First of all, multiply the coefficient of x by the number on each side.

6*4x² = 3*4x

24x² = 12x

Divide both sides by 12

2x² = x

Divide both sides by x

2x = 1

Solve for x

x = 1/2

When you go from one side to the other side of the figure you are either multiplying or dividing by 4 :)

A man drove to work at an average rate of speed 60 miles per hour and

expeople1 [14]

let x = miles

we have x miles/ 60mph plus x miles / 40 mph = 1 hour

x/60 + x/40 = 1

we need to calculate 2x for the round trip

calculate common denominator and rewrite the 2 fractions:

2x/120 + 3x/120 = 1

5x= 120

x = 120/5 = 24 miles

24*2 = 48 miles total

check:

1 way would be 48/2 = 24 miles

24/60 = 0.4 hours to drive 24 miles at 60 mph

24/40 = 0.6 hours to drive 24 miles at 40 mph

0.6 +0.4 = 1 hour

Find the vertex, zero(s), and y-intercept of the graph of y = –x2 + 4x + 32.

xxMikexx [17]

Answer:

The correct option is A.

Step-by-step explanation:

The given equation is

$y=-x^2+4x+32$

Put x=0, in the given equation.

$y=-(0)^2+4(0)+32=32$

The y-intercept is (0,32).

Put y=0, to find the x-intercept.

$0=-x^2+4x+32$

$0=-x^2+8x-4x+32$

$0=-x(x-8)-4(x-8)$

$0=-(x+4)(x-8)$

$x=-4,8$

Therefore the y-intercepts are (-4,0) and (8,0).

The vertex of a parabola $f(x)=ax^2+bx+c$ is

$(-\frac{b}{2a},f(-\frac{b}{2a}))$

$-\frac{b}{2a}=-\frac{4}{2(-1)}=2$

Put x=2 in the given function.

$y=-(2)^2+4(2)+32$

$y=-4+8+32$

$y=36$

The vertex is (2,36).

Therefore option A is correct.
