Solve the following system of equations for a and for b:

viktelen [127]

Answer:

$a=3\\b=1$

Step-by-step explanation:

$9a+3b=30\\8a+4b=28$

Let's solve the second equation for a to later on replace it in the first equation.

$8a+4b=28\\8a=28-4b\\a=\frac{28-4b}{8}$

Now plug this into the first equation.

$9a+3b=30\\9(\frac{28-4b}{8})+3b=30$

Distribute the 9

$(\frac{252-36b}{8}) +3b=30$

Break down the fraction.

$\frac{252}{8}-\frac{36b}{8}+3b=30$

Simplify.

$\frac{63}{2}-\frac{9}{2}b+3b=30$

Subtract $\frac{63}{2}$

$-\frac{9}{2}b+3b=30-\frac{63}{2}$

Combine like terms.

$\frac{-9+2*3}{2}b=\frac{30*2-63}{2}$

$\frac{-9+6}{2}b=\frac{60-63}{2}$

$\frac{-3}{2}b=\frac{-3}{2}$

Muliply by the reciprocal or inverted fraction next to b.

$(-\frac{2}{3})(-\frac{3}{2}) b=-\frac{3}{2}(-\frac{2}{3})$

$b=1$

Now plug this value into any of the equations to find the value of a.

$8a+4b=28\\8a+4(1)=28\\8a+4=28\\8a=28-4\\8a=24\\a=\frac{24}{8}\\ a=3$

Use the formula to find the slope of the line that passes through these two points. Show your work.

Dafna1 [17]

Answer:

Solution given:

$(x_1,y_1)=(1,2)$

$(x_2,y_2)=(7,7)$

now

slope: $\frac{y_2-y_1}{x_2-x_1}=\frac{7-2}{7-1}=\frac{5}{6}$

Slope: 5/6

Under his cell phone plan, Xavier pays a flat cost of $44 per month and $3 per

wolverine [178]

Answer:

Answer:

4.8 gigabytes

Step-by-step explanation:

Let the number of gigabytes of data = x

Xavier pays a flat cost of $44 per month and $3 per gigabyte. He wants to keep his bill at $58.40 per month.

The above expression above is represented by the equation:

$44 + $3 × x = $58.40

44 + 3x = 58.40

Solving for x

Subtract 44 from both sides

44 - 44 + 3x = 58.40 - 44

3x = 14.4

x = 14.4/3

x = 4.8 gigabytes
