Let c represent the number of children Mama has. The number of notebooks she has is
.. 13c +8 = 15c
.. 8 = 2c
.. c = 8/2 = 4

Mama has 4 children and 60 notebooks.

Step-by-step explanation:

the domain is the set or interval of all valid x values.

the range is the set or interval of all valid y values.

1.

domain = {-1, 2, 5}

range = {0, 2, 3, 7}

function : no, because x = -1 has 2 different y values assigned (7 and 2). that violates the definition of a function.

2.

domain = {-3, -2, -1, 1, 4}

range = {-5, -1, 0, 2}

function : yes. every x bake has exactly one y value assigned.

3.

domain = {4, 6, 7}

range = {-1, 2, 3, 5}

function : no, because x = 4 has 2 different y values assigned (2 and 5).

4.

domain = [-3, 3) "3" is not included, hence the empty dot

range = [-4, 5]

function : yes

5.

domain = (-infinity, +infinity) "infinity" is not a possible value, so the limits are not included.

range = [-1, 2]

function : yes

6.

domain = [-2, +infinity)

range = (-infinity, +infinity)

function : no. except for x = -2 all x values have 2 different y values assigned.

X + y = 5 ; x - y =3 solve using linear combination
Bas_tet [7]

Answer:

x = 4

y = 1

Step-by-step explanation:

use one equation to solve for one variable.

y = 5 - x

Now plug the value of y in the other equation

x - (5-x) = 3

x+x= 3+5

2x=8

x=4

Now use the value of x to find the value of y on the first equation

y = 5 - x

y = 5 - 4

y = 1
