I would add like terms, meaning subtract 6.4 from both sides.

3.5n = 36.1

<h2>Answer:</h2>

n= 361/35

alternative forms:

n= 10 11/35 or n= 10.3142857

<h2>Step-by-step explanation:</h2>

3.5n+6.4=42.5

move constant to the right

3.5n=42.5-6.4

subtract 42.5 to 6.4

3.5n=36.1

divide both sides by 3.5

----------------

n=361/35

the axis of symmetry for the graph of the function is f(x) = 1/4x2 bx 10 is x = 6. what is the value of b?

Lady bird [3.3K]

we have

$f(x)=\frac{1}{4} x^{2} +bx+10$

This is a vertical parabola open upward

The axis of symmetry is equal to the x-coordinate of the vertex

The vertex is the point (h,k)

the equation of the axis of symmetry is $x=h$

In this problem

$x=6$

so the x-coordinate of the vertex is $h=6$

<u>Convert the quadratic equation in vertex form</u>

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)-10=\frac{1}{4} x^{2} +bx$

Factor the leading coefficient

$f(x)-10=\frac{1}{4}(x^{2} +4bx)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$f(x)-10+b^{2}=\frac{1}{4}(x^{2} +4bx+4b^{2})$

Rewrite as perfect squares

$f(x)+(b^{2}-10)=\frac{1}{4}(x+2b)^{2}$

$f(x)=\frac{1}{4}(x+2b)^{2}-(b^{2}-10)$

remember that

$h=6$

$(x+2b)=(x-6)$

$2b=-6$

$b=-3$

substitute in the equation

$f(x)=\frac{1}{4}(x-6)^{2}-((-3)^{2}-10)$

$f(x)=\frac{1}{4}(x-6)^{2}+1$

therefore

<u>the answer is</u>

$b=-3$

Plzzz help, the quicker the better!!!!!!

pishuonlain [190]

Answer:

Step-by-step explanation:

here,

the lower angle when sumed,

it is like: 154+a=180 (let angle be a) being supplementary angle sum is 180

so value of a becomes 26

then,

the above angle x is corresponding to angle a (a=x)

So value x is 26

What is the equation of the line that passes through the point (-3,2) and is parallel to y=2x+8

Tom [10]

The line we are searching for has the same slope because both lines are parallel.

The given equation y = 2x + 8 has a slope of 2.

We need the point-slope formula, the slope 2 andbthe given point.

y - y1 = m(x - x1)

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

y - 2 = 2(x + 3)

y - 2 = 2x + 6

We now solve for y.

y = 2x + 6 + 2

The equation we want is y = 2x + 8.
