Shtirlitz [24]

The answer is 5 x 4 x 3 x 2 x 1 or 5! (! = factorial)
It is a permutation, as the order matters.

* Jenny marked on a coordinate plane all points with the first coordinate an integer between −12 and 7 and the second coordinate

Nat2105 [25]

Answer:

Jenny marks 414 different points on the coordinate plane.

Step-by-step explanation:

A point on a coordinate plane is represented by (x, y)

The possible values of x include all the integers between -12 and 7; that is,

-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6.

The possible values of y include all the integers between -12 and 12; that is,

-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.

This means that each x-value can take on each y-value.

There are 18 x-values and 23 y-values.

Each x-value can form 23 different coordinates with all the available y-values.

18 x-values will form 18 × 23 different coordinates with the all the available y-values.

The total number of points that Jenny marks = 18 × 23 = 414.

Hope this Helps!!!

Help me solving number 22 & 24. Thanks:)

aksik [14]

Answer:

Question 22

x intercept is 7

y intercept is 4

The answer is C

Question 24

x intercept is -4

y intercept is 7

The answer is B

Step-by-step explanation:

x and y intercepts are the points at which the graph meets x and y axes.

x and y intercepts can be found the following way,

y intercept - substitute 0 to x

x intercept - substitute 0 to y

Question 22

$7y=28-4x$

Substitute x=0 to find the y intercept

$7y=28-4*0$

= $7y=28$

= $y=4$

Substitute y=0 to find x intercept

$7*0=28-4x$

= $0=28-4x$

= $4x=28$

= $x=7$

Therefore,

x intercept is 7

y intercept is 4

The answer is C

Question 24

$4y=7x+28$

Substitute x=0 to find the y intercept

$4y=7*0+28$

= $4y=28$

= $y=7$

Substitute y=0 to find x intercept

$4*0=7x+28$

= $0=7x+28$

= $-7x=28$

= $x=-4$

Therefore,

x intercept is -4

y intercept is 7

The answer is B
