Equation C: y = 2x + 8

ExtremeBDS [4]

Answer:

No solution

Step-by-step explanation:

we have

$y=2x+8$ -----> equation C

$y=2x+2$ -----> equation D

Comparing equation C and equation D

The two lines are parallel because the slope is equal ( m=2)

The y-intercept are different

The lines are different parallel lines

therefore

The system of equations has no solution

Help if you do this you will get seven years of good luck if you don't you will get seven years of bad luck: (SAT Prep): Find th

KatRina [158]

Answer:

$Slope=\frac{7}{2}=3.5$

Step-by-step explanation:

Slope of line: $Slope\ of\ line\ passing\ through\ (x_1,y_1)\ and\ (x_2,y_2)\ is\ given\ by\ \frac{y_2-y_1}{x_2-x_1}$

$Here\ (x_1,y_1)=(\frac{2}{7},5)\\\\(x_2,y_2)=(10,39)\\\\Slope=\frac{39-5}{10-\frac{2}{7}}\\\\Slope=\frac{34}{\frac{68}{7}}\\\\Slope=\frac{34\times 7}{68}\\\\Slope=\frac{7}{2}=3.5$

The diameter of a standard basketball is 9.5 inches. If the basketballs are covered in rubber, what is the minimum amount of rub

Softa [21]

Answer:

The minimum amount of rubber needed is 1,134 square inches

Step-by-step explanation:

we know that

The surface area of a sphere (basketball ) is given by the formula

$SA=4\pi r^{2}$

we have

$r=9.5/2=4.75\ in$ ----> the radius is half the diameter

$\pi=3.14$

substitute

$SA=4(3.14)(4.75)^{2}=283.385\ in^2$

Multiply by 4 (because are four basketballs)

$283.385(4)=1,133.54\ in^2$

therefore

The minimum amount of rubber needed is 1,134 square inches
