Determine the exact value of k so that the quadratic function f(x) = x2 - kx + 5 has only one zero.

What are the roots of the polynomial f(x)=x^2+9x-70?

Answers

Roots of the polynomial are values of x when f(x)=0,so
to find the roots of the polynomial we need to solve the equation
x²+9x-70=0    , a=1, b=9,c=-70     

x= \frac{-b+/- \sqrt{ b^(2)-4ac } }{2a}

x= (-9+/- √(81+4*1*70) )/(2) = (-9+/- √(361) )/(2)= (-9+/-19)/(2) x_(1)=5, x_(2)=-14

Mr Solidarios charged Randolf Php 320.00 for parts and Php 150.00 per hour for labor to repair his bicycle.If he spent 3 hours repairing his bicycle,how much does Randolf owe him?

Answers

Answer:

  Php 770.00

Step-by-step explanation:

The cost of labor is ...

  (hours) × (hourly rate)

  = (3 h) × (Php 150.00/h) = Php 450.00

The total cost is ...

  total cost = cost of labor + cost of parts

  = (Php 450.00) + (Php 320.00) = Php 770.00

Randolf owes Mr. Solidarios Php 770.00 for the repair.

Solve the rational equation

1/x+3/8=1/4

Answers

Step 1: Subtract 3/8 from both sides
1/x+3/8-3/8=1/4-3/8
1/x=1/4-3/8

Step 2: Multiply 1/4 by 1/2
1/x=(1/4)(1/2)-3/8
1/x=2/8-3/8

Step 3: Subtract
1/x=-1/8

Step 5: Multiply by x on both sides
1/x(x)=-1/8(x)
1=-1/8x

Step 6: Divide -1/8
1/(-1/8)=-1/8x/(1/8)
*You can times flip
1(-8)=-1/8x(8)
-8=-x
*Divide by -1
-8/-1=-x/-1
8=x

2. Solve and graph.(a) Write the inequality as two inequalities without absolute value.
(b) Solve the inequality and write the solution set.
(c) Graph the solution on a number line.

Answers

|x - 2| > 5

if x >= 2
x - 2 > 5
x > 7

if x < 2
-x + 2 > 5
x < -3

hence the solution is: x belongs to (-inf, -3)U(7, inf)
