Answer:

  (ii) (x, y, z) = (110°, 30°, 30°)

  (iii) (x, y, z) = (110°, 70°, 70°)

Step-by-step explanation:

The things you need to know and use are ...

  Opposite angles of a parallelogram are congruent.

  Adjacent angles of a parallelogram are supplementary.

  Alternate interior angles between a transversal and parallel lines are congruent.

  Corresponding angles where a transversal crosses parallel lines are congruent.

__

(ii) Angles B and D are opposite, so congruent:

  x = 110°

Angle DAB is supplementary to angle B, so is 70°. That means z is ...

  z = 70° -40° = 30°

Angle y is "alternate interior" relative to z, so is congruent to z:

  y = 30°

__

(iii) Angle x is adjacent to angle N, so is supplementary to 70°.

  x = 180° -70° = 110°

Angle y is opposite angle N, so is congruent.

  y = 70°

Angle z is corresponding to angle N, so is congruent. (It is also "alternate interior" with respect to angle y, so is congruent to y.)

  z = 70°

A store is having a sale on walnuts and chocolate chips. For 7 pounds of walnuts and 9 pounds of chocolate chips, the total cost
Jlenok [28]

Answer:

  • Walnuts  cost $1.75, chocolate chips cost $2.75

Step-by-step explanation:

<h3>Let the costs be:</h3>

  • Walnuts - x
  • Chocolate chips - y

<h3>Set equations as per question</h3>

For 7 pounds of walnuts and 9 pounds of chocolate chips, the total cost is $37:

  • 7x + 9y = 37

For 5 pounds of walnuts and 3 pounds of chocolate chips, the total cost is $17:

  • 5x + 3y = 17

<h3>Solve the system by elimination</h3>

Multiply the second equation by 3 and subtract the first equation, solve for x:

  • 3(5x + 3y) - (7x + 9y) = 3(17) - 37
  • 15x + 9y - 7x - 9y = 51 - 37
  • 8x = 14
  • x = 14/8
  • x = 1.75

Find the value of y:

  • 7*1.75 + 9y = 37
  • 12.25 + 9y = 37
  • 9y = 37 - 12.25
  • 9y = 24.75
  • y = 24.75/9
  • y = 2.75

Which table represents a nonlinear function?
Artist 52 [7]
The first box is correct because if drawn on a praph it would show that it has a curve. Also another way to find out if it is nonlinear or linear is because the x-axis is increasing and the y-axis is decreasing. Hope this helps :)
