The price for the text message that is charged by the cellphone company will be $0.2.

Based on the above, the equation to represent the information given will be:

m + 104n = 50.79 ....... equation i

m + 83n = 46.59 ......... equation ii

Subtract equation ii from i

21n = $4.2

Divide both side by 21

21n/21 = $4.2/21

n = $0.2

Answer:

x= plus or minus square root of 19 -4

Step-by-step explanation:

x^2+8x ___=3

take half of your b term (8) and then multiply by two and add or subtract it to both sides

x^2+8x+16=3+16

then combine like terms

x^2+8x+16=19

then factor your quadratic equation

(x+4)^2=19

now solve for x

take the square root of (x+4)^2 to get rid of the ^2

you then also have to square the 19 because what you do to one side you have to do to the other

(x+4)= square root of 19

subtract 4 from both sides

x= plus or minus square root of 19 -4

Answer:

Step-by-step explanation:

Divide the coefficient of x by 2

8/2 = 4. Now find the square of 4 = 4² = 16

Add 16 to both sides of the equation

x² + 8x + 16 = 3  + 16

x² + 2* x * 4 + 4² = 19

{Compare with a² + 2ab + b² = (a + b)² }

(x + 4)² = 19

Both sides take square root,

[tex]\sqrt{(x+ 4)^{2}}=\sqrt{19}\\\\x + 4 = \sqrt{19}[/tex]

x + 4 = ± 4.36

x + 4 = 4.36   ; x +  4 = -4.36

x = 4.36 -4     ;    x  = -4.36 - 4

x = 0.36         ; x = - 8.36

Answer:

19xyz

Step-by-step explanation:

First, let us just forget about the xyz at the end of each number. Now, we just have the simple addition problem 3 + 7 + 9. First. let us do 3 + 7, which gives us 10. Now, let us take our 10 and add the 9 to it. 10 + 9 is 19. Now, we can add our xyz back to the equation. Now, we have 19xyz. As we do not know anything about what x, y, or z equals, nothing further can be done with this equation. Therefore, the answer is 19xyz.

Answer:

1) [tex]y-6=-\frac{2}{3} (x-1)[/tex] and 2) [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Step-by-step explanation:

Ikr the bots are annoying.

Point-slope form is written as: [tex]y-y_1=m(x-x_1)[/tex]

Slope intercept form is written as: [tex]y=mx+b[/tex]

We also need to find the slope before putting it in this form, which can be done by [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

1) Points given are (1,6) and (-2,8)

Slope: [tex]m=\frac{8-6}{-2-1} =-\frac{2}{3}[/tex]

You can choose either of the two points to put into the formula. I just chose (1,6)

Answer: [tex]y-6=-\frac{2}{3} (x-1)[/tex]

2) Same points as before and we have the same slope as before. All we need is to find the y intercept which is our b in the equation. You can easily do this by plugging in a point and solving for b. I will choose point (1,6) again.

[tex]6=-\frac{2}{3} (1)+b[/tex]

[tex]6=-\frac{2}{3} +b[/tex]

[tex]6+\frac{2}{3}=-\frac{2}{3} +\frac{2}{3} +b[/tex]

[tex]b=6+\frac{2}{3}=\frac{20}{3}[/tex]

Answer: [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

let

Total budget of the family = x

Monthly housing budget = 28%

percentage monthly housing budget = 28% of x

= 28/100 × x

= 0.28x

Fraction of the family’s budget that is spent on housing = 28/100 × x

= 7/25 × x

= 7/25x

Therefore, fraction of the family’s budget that is spent on housing is 7/25
