Answer:

The dog biscuits are approximately 69% off.

Step-by-step explanation:

(1 - 0.69/2.23) * 100

(223/223 - 69/223) * 100

154/223 * 100 = 69%

How do you do this question?
Cloud [144]

Answer:

  (B) only I and II

Step-by-step explanation:

An odd relation is symmetrical about the origin. All of the relations are odd.

An even relation is symmetrical about the y-axis. Only the first two relations are even.

_____

The graph shows the first relation is that of a circle. It is symmetrical about its center at the origin and about any diameter, including the y-axis.

The second relation is a degenerate hyperbola. It graphs as the pair of lines y=x and y=-x. It is symmetrical about both the origin and the y-axis. (It also has other lines of symmetry.)

The third relation is a line with slope -1 (represented by dots). It is symmetrical about the origin, but not the y-axis. It is only an odd relation.

Solve the system of linear equations below, using substitution method.
Levart [38]

Answer:

x = 0

y=4

Step-by-step explanation:

Given

8x + 9y = 36

3x + 4y = 16

Required

Solve using substitution method

Make x the subject in 3x + 4y = 16

3x = 16 - 4y

Divide through by 3

x = \frac{1}{3}(16 - 4y)

Substitute \frac{1}{3}(16 - 4y) for x in 8x + 9y = 36

8*\frac{1}{3}(16 - 4y) + 9y = 36

\frac{8}{3}(16 - 4y) + 9y = 36

Open bracket

\frac{8}{3}*16 - \frac{8}{3}*4y + 9y = 36

\frac{8*16}{3} - \frac{8*4y}{3} + 9y = 36

Multiply through by 3

3 * \frac{8*16}{3} - 3 *\frac{8*4y}{3} +3* 9y = 36*3

8*16 - 8*4y +3* 9y = 36*3

128- 32y +27y = 108

128-5y = 108

Collect Like Terms

-5y = 108-128

-5y = -20

Make y the subject

y = \frac{-20}{-5}

y=4

Substitute 4 for y in  x = \frac{1}{3}(16 - 4y)

x = \frac{1}{3}(16 - 4*4)

x = \frac{1}{3}(16 - 16)

x = \frac{1}{3}(0)

x = 0
