How will the solution of the system y &gt; 2x + Two-thirds and y &lt; 2x + One-third change if the inequality sign on both inequ
zubka84 [21]

Answer:

From not having solution the system changed to have solution

Step-by-step explanation:

step 1

we have

y>2x+\frac{2}{3} ----> inequality A

y ----> inequality B

Solve the system of inequalities by graph

using a graphing tool

The system has no solution , because the dashed lines are parallel lines

see the attached figure N 1

step 2

we have

y ----> inequality A

y>2x+\frac{1}{3} ----> inequality B

Solve the system of inequalities by graph

using a graphing tool

The solution is the shaded area between the two dashed lines

see the attached figure N 2

therefore

From not having solution the system changed to have solution

Ashley, Milan, and Carlos sent a total of 131 text messages over their cell phones during the weekend. Carlos sent 7 times as ma
nordsb [41]

Answer:

Ashley= 15

Milan= 11

Carlos= 105

Step-by-step explanation:

Let, A, M and C denotes Ashley, Milan and Carlos respectively.

A+M+C= 131 (according to the question)

Here,

C= 7A

A= M+ 4

So, M= A - 4

Now,

A+M+C = 131

or, A+ A-4+ 7A = 131 (putting the values)

or, 9A - 4 = 131 (adding like terms i.e. A + A + 7A)

or, 9A = 131 + 4

or, 9A = 135

or, A = 135 / 9

So, A = 15

C= 7A = 7×15= 105

M= A-4 = 15 - 4 = 11
