Let the number be x,
(1/2)x=1+(1/3)x
Solving for x,
(1/2)x-(1/3)x=1+(1/3)x-(1/3)x
(1/2)x-(1/3)x=1
(1*3/6)x-(1*2/6)x=1
(3/6)x-(2/6)x=1
(1/6)x=1
6*(1/6)x=6*1
Therefore, x=6

(1/2)x = (1/3)x +1
-(1/3)x -(1/3)x

(1/6)x=1
*6 *6
x=6

And so x=6, or your number is 6

How do you do these?

fiasKO [112]

I'll do #6.

The axis of symmetry is the x-coordinate of the vertex, which in this case, is (0,-4). So the axis of symmetry is x=0.

The vertex is in the above answer. Since this is a quadratic function, there are no boundaries, the domain is All Real Numbers.

The range goes up forever from the vertex. The vertex is (0,-4), so, the minimum y value is -4. The range is y is greater than or equal to -4, or in interval notation: [-4,infinity]

Hope this helps!

A cab charges 1.45 for the flat fee and 0.55 for each mile. Write and solve an inequality to determine how many miles Ariel can

Tatiana [17]

M = mile

.55m + 1.45 [less than or equal to] 35

subtract 1.45

.55m = 33.55

divide by .55

m = 61 miles or less

You travel between these two mile markers and then find your average speed in miles per hour. Which equation does NOT represent

Jet001 [13]

Answer:

The correct option is C.

Step-by-step explanation:

The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.

So total time taken by car is

$4:30-3:00=1:30$

It means total time taken by car is 1.5 hour.

The distance in first figure is 50 miles and the speed in second figure is 155 miles.

So total distance travelled by car is

$155-50=105$

It means total distance travelled by car is 105 miles.

The formula of speed is

$Speed=\frac{Distance}{Time}$

$Speed=\frac{105\text { miles }}{1.5\text{ hours}}$

Therefore option B represents the solution. Option B is incorrect.

Multiply both sides by 1.5 hours.

$1.5\text{ hours}\times Speed=105\text { miles }$

Therefore option D represents the solution. Option D is incorrect.

Divide both sides by speed.

$1.5\text{ hours}=\frac{105\text { miles }}{Speed}$

Therefore option A represents the solution. Option A is incorrect.

Option C can not represent the solution, therefore option C is correct.

If two equations in a linear system have the same slope and the same -intercepts, the system will have:'

stiks02 [169]

Answer:

The answer to your question is a. Infinite solution

Step-by-step explanation:

When two lines have the same slope and the same intercepts, this means that these lines are the same so they system of equations will have infinite solutions.

If the lines do not cross, there will be no solution.

If the lines cross in one point there will be one solution

If there are a quadratic and a linear function they will cross in two points.
