3. Keenen gets on the train to ride around the park. As he is riding the train the conductorsays that they are going to build a
Nataly [62]
First, we need to get the slope of the equation of the train tracks. We can transform the given equation into the slope-intercept form.
4x +2y = 16
y = -2x +8

The slope of the equation is -2.

A perpendicular line will have the same slope but the opposite sign.
So, the slope of the line of the train crossing is 2. Since, it will pass through the point (8,15), the slope-intercept form can also be used to solve for the equation.
 y = mx + b

The slope is 2, so m=2. We solve b by substituting the coordinates.
15 = 2(8) +b
b = -11

The equation is now,
y = -2x - 11

Or it can also be expresses as:
2x - y = 11

sing the expression x + 3, write one equation that has one solution, one equation that has no solution, and one equation that ha
8090 [49]

Answer:  one solution  x + 3 = 5   x = 2   no other other value for x is possible

No solution:  (x + 3) = 2(x +3)  

Infinitely many solutions:  x+3 = 3 + x

Step-by-step explanation:

why (x + 3) = 2(x +3)  has no solution. Can you solve?

x+3=2x+6 -x=3 x=-3 substute -3 for x

(-3)+ 3)= 2[(-3) +3]

-3+3 = -6 +3

0 = -3 False!

x+3 = 3 + x  has infinitely many solutions. Substitute any number for x, and the equation is true   (5)+3=3+(5) 8=8 .  11111+3 =3+11111  11114=11114

1. Solve the equation using the zero-product property.<br> -x(5x – 4) = 0
Oxana [17]

Answer:

x = 0, 4/5

Step-by-step explanation:

The zero-product property states that if the product of a and b is zero, then either a = 0, b = 0, or both terms equal zero

  • Here our a term is -x and our b term is (5x - 4)
  • Setting each term equal to zero and solving for x we get
  • -x = 0 → x = 0
  • 5x - 4 = 0 → 5x = 4 → x = 4/5
