Answer:

y=mx+b <3 have a nice day!

Step-by-step explanation:

The graph of which function has a minimum located at (4, –3)?f(x) = x2 + 4x – 11
f(x) = –2x2 + 16x – 35
f(x) = x2 – 4x + 5
f(x) = 2x2 – 16x + 35

Answers

Answer:

None of the options is the answer to the question

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

f(x)=a(x-h)^(2)+k

where

(h,k) is the vertex of the parabola

case A) we have

f(x)=x^(2)+4x-11

In this case the x-coordinate of the vertex will be negative

therefore

case A is not the solution

case B) we have

f(x)=-2x^(2)+16x-35

This case is a vertical parabola open downward (the vertex is a maximum)

The vertex is the point (4,-3)but is not a minimum

see the attached figure

therefore

case B is not the solution

case C) we have

f(x)=x^(2)-4x+5

Convert into vertex form

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

f(x)-5=x^(2)-4x

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

f(x)-5+4=(x^(2)-4x+4)

f(x)-1=(x^(2)-4x+4)

Rewrite as perfect squares

f(x)-1=(x-2)^(2)

f(x)=(x-2)^(2)+1 --------> vertex form

The vertex is the point (2,1)

therefore

case C is not the solution

case D) we have

f(x)=2x^(2)-16x+35  

Convert into vertex form

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

f(x)-35=2x^(2)-16x

Factor the leading coefficient

f(x)-35=2(x^(2)-8x)

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

f(x)-35+32=2(x^(2)-8x+16)

f(x)-3=2(x^(2)-8x+16)

Rewrite as perfect squares

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

f(x)=2(x-4)^(2)+3 --------> vertex form

The vertex is the point (4,3)

therefore

case D is not the solution

The answer to the question will be the function

f(x)=2x^(2)-16x+29

ind the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2). (answer in slope-intercept form)

Answers

we have that
Find the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2)
y - 3x = – 8-----> y=3x-8------> the slope m=3

we know that
if two lines are perpendicular 
then
m1*m2=-1
m1=3
so
m2=-1/3

with m=-1/3 and point (3, 2) find the equation of the line
y=mx+b
2=(-1/3)*3+b------> 2=-1+b-----> b=3

the equation of the line is
y=(-1/3)x+3

the answer is
y=(-1/3)x+3

Find 15% of 60
====================================================================
SOLVING...

To find 15% of 60 just multiply 0.15 (note: 0.15 = 15%) by 60
0.15 x 60 = 9
or 
15% x 60 = 9
(either way works)
====================================================================
Your Answer - 9 is 15% of 60
