How would I graph x= -1?

Mathematics
1 answer:
olga nikolaevna [1]3 years ago
8 0

Answer:

as a vertical line that passes through (-1,0)

Step-by-step explanation:

this line doesn't have a slope nor y-intercept and is parallel to the y-axis. its x-intercept should be (-1,0) and it should continue in both vertical directions from that point, passing through each coordinate pair where x = -1 [(-1,3); (-1,-5); etc]

7) The area of rectangle A is twice the area of square B. Find x.<br> 12
Veronika [31]

Answer:

Step-by-step explanation:

A=2B

AreaA= Area of a rectangle=Base* height = base (12-x)*height(4) = 48-4x

AreaB = Area of rectangle=base(x) *Height(x) =x^2

Since A=2B

48-4x =2x^2

Divide both sides of the equation by 2

24-2x=x^2

Put everything all on one side

X^2-2x-24=0

(x+4)(x-6)=0

X=-4 and x=6

Only x makes sense since it’s not negative or else your base or one of your sides would be negative

So x=6

Ten individuals are candidates for a committee. Two will be selected. How many different pairs of individuals can be selected?
Nina [5.8K]

Answer:

45

Step-by-step explanation:

The different pairs of individual can be computed using rule of combination.

The combination is denotes as nCr.

nCr=n!/(r!(n-r)!)

In the given problem n=total candidates=10 and r= Selected candidates=2.

10C2=10!/(2!(10-2)!)

10C2=10*9*8!/(2!8!)

10C2=90/2

10C2=45

So, 45 different pairs of individuals can be selected.

A car is traveling at a steady speed. It travels 2 1/3 miles in 3 1/2 minutes. How far will it travel in 24 minutes? How far wil
Vikki [24]

Answer:

a) distance traveled is 16 miles.

b) distance traveled is 40 miles.

Step-by-step explanation:

Speed is a scalar quantity which describe the rate of distance moved with time.

i.e speed = \frac{distance}{time}

Given that: distance = 2 1/3 miles = \frac{7}{3} miles, time = 3 1/2 minutes = \frac{7}{2} minutes.

Then;

speed = \frac{7}{3} ÷ \frac{7}{2}

          = \frac{7}{3} x \frac{2}{7}

          = \frac{2}{3}

The car's steady speed is 0.67 miles per minute.

a) when the time is 24 minutes, the distance covered can be determine by:

distance = speed x time

              = \frac{2}{3} x 24

              = 16

distance traveled is 16 miles.

b) When the time is 1 hour (60 minutes), the distance traveled can be determined by:

distance = speed x time

              = \frac{2}{3} x 60

              = 40

distance traveled is 40 miles.

Someone please help??
Xelga [282]

Answer:

x-axis

Step-by-step explanation:

The asymptote is a straight line that the curve gets closer and closer to but never touches it.

The given exponential function is f(x)=3^x.

The given graph has a horizontal asymptote,

The equation of this horizontal asymptote is y=0.

This is also refers to as the x-axis.

Therefore the asymptote is the x-axis.
