Answer:

Step-by-step explanation:

Here, x² + 13x = -3

Here, as x² + 13x would remain same, you have to add or subtract equivalent number from both sides,

x² + 13x + 3 = 0

Sergeu [11.5K]

Simplify the Value of:

6x + 1 The equation is already simplified, There are no like terms.

You cannot factor 6x + 1 either

Domain of:

6x + 1

Solution: [ - ∞ < x < ∞ ]

Interval Notation: [ (- ∞, ∞) ]

Range of:

6x + 1

Solution: [ - ∞ < f(x) < ∞ ]

Interval Notation: [ (- ∞, ∞) ]

Parity of:

6x + 1 =====> Neither even nor odd

Axis interception points of:

6x + 1

x- Intercepts ( - 1 / 6, 0 )

y- Intercepts ( 0, 1 )

Inverse of:

6x + 1 =====> x - 1 / 6

Slope of:

6x + 1

Answer: ======> m = 6

Two people are driving to work at different constant speeds. The graph below shows the distance traveled over time by driver 1.

Luden [163]

Answer:

5 mph

Step-by-sep explanation:

To find of out the difference between the speed of the two drivers in miles per hour (not in miles per minute), first, calculate the unit rate or speed of driver 1 using the graph, and driver 2 using the table given.

Unit rate/speed = distance travelled/time = y/x.

Speed of Driver 1/unit rate:

The graph shows 1.5 miles (y) is travelled in 2 minutes (x).

Convert the 2 minutes to hour, you will have:

$\frac{2}{60} = \frac{1}{30} hr$

Speed in mph = $\frac{y}{x} = \frac{1.5}{\frac{1}{30}} = 1.5*\frac{30}{1} = 45$

Speed of Driver 1 in mph = 45 mph

Speed of Driver 2/unit rate:

The table shows 2.5 miles (y) is travelled in 3 minutes (x).

Convert the 3 minutes to hour, you will have:

$\frac{3}{60} = \frac{1}{20} hr$

Speed in mph = $\frac{y}{x} = \frac{2.5}{\frac{1}{20}} = 2.5*\frac{20}{1} = 50$

Speed of Driver 2 in mph = 50 mph

Difference between the speed of the two drivers = 50 - 45 = 5 mph

$\pi$ is irrational number

$-100$ is integer but not whole number

$-34$ is integer but not whole number

$-4$ is integer but not whole number

$-\dfrac{8}{4} =-2$ is integer but not whole number

$0.333...=\dfrac{1}{3}$ is rational number

$0.456783...$ is irrational number

$3$ is whole number

$9.23456=\dfrac{923,456}{100,000}$ is rational number

$\sqrt{4}=2$ is whole number

$\sqrt{8}=2\sqrt{2}$ is irrational number

$\dfrac{1}{2}$ is rational number

$\dfrac{49}{7}=7$ is whole number

$\dfrac{89}{10}$ is rational number

$zero$ is whole number
