Answer:

y = 6x+9

Step-by-step explanation:

We have given an equation.

2x+12y=-1                      eq(1)

y = mx+c is slope-intercept form of equation of line where m is slope and c is y intercept.

We can write eq(1) in slope-intercept form:

12y = -2x-1

y = 1/12(-2x-1)

y = -1/6x-1/12

let m₁ is slope of given line which is equal to -1/6.

Perpendicular lines have slopes negative reciprocals of each other.

Let m₂ is slope of perpendicular line.

m₂ = 6 and  we have given y-intercept = 9.

Putting the value of c and m₂ in slope-intercept form of equation, we have

y = 6x+9 is slope-intercept of line that is  perpendicular to the given line and passes through the point (0,9).

Answer:

y = 12x + 9 is the answer.

Step-by-step explanation:

Since the given equation is 2x + 12 y = -1

12y = -2x -1

y=-\frac{1}{12}(2x+1)

y=-\frac{1}{12}x-\frac{1}{12}

Now this line is in the form of y = mx + c

Here m = slope = -1/12

We have to calculate the slope of another line perpendicular to this line and passing through (0, 9).

Let the equation is y = m' + c'

We know m×m' = -1 for two perpendicular lines

-(\frac{1}{12})(m')=-1

m' = 12

Therefore the equation will be

y = 12x + c'

Since this line passes through ( 0, 9)

9 = 12×0 + c'

c' = 9

Now the equation will be

y = 12x + 9

This is the answer.

According to the Fundamental Theorem of Algebra, the graph of f(x) = x2 - 4x + 3, has roots. From the graph we can see that it h
andreyandreev [35.5K]

Answer:

The graph f(x)=x^2-4x+3  has two zeros namely 3 and 1.

Step-by-step explanation:

Consider the given equation of graph f(x)=x^2-4x+3

According to the Fundamental Theorem of Algebra

For a given polynomial of degree n can have a maximum of n roots.

Thus, for the given equation f(x)=x^2-4x+3  the degree of polynomial is 2 , thus the function can have maximum of 2 roots.

We know at roots the value of function is 0 that is f(x) = 0,

Substitute f(x) = 0 , we get, f(x)=x^2-4x+3=0

This is a quadratic equation, x^2-4x+3=0

We first solve it manually and then check by plotting graph.

Quadratic equation can be solved using middle term splitting method,

here, -4x can be written as -x-3x,

x^2-4x+3=0 \Rightarrow x^2-x-3x+3=0

\Rightarrow x(x-1)-3(x-1)=0

\Rightarrow (x-3)(x-1)=0

Using zero product property, a\cdot b=0 \Rightarrow a=0\ or \ b=0

\Rightarrow (x-3)=0 or \Rightarrow (x-1)=0

\Rightarrow x=3 or \Rightarrow x=1

Thus, the two zero of f(x) are 3 and 1.

We can also see on graph attached below that the graph f(x)=x^2-4x+3  has two zeros  namely 3 and 1.

Solve the percent equation. 646 is what percent of 340?
ella [17]
646 is 190% of 340

Simply do the following,

1) divide,

646 \div 340 = 1.9

2) multiply the above answer by 100

1.9 \times 100 = 190

3) dock on that percent sign,

190\%
