Step-by-step explanation:

it will be irrational  

Answer:

7 hours and 30 minutes

Step-by-step explanation:

[tex]240 \div 4 = 60km \: per \: h[/tex]

[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]

It will take motor bike 7.5 hours to cover 450 Km of distance.

Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.

Mathematically-

S = Δd/Δt  or   S = {d(2) - d(1)}/{t(2) - t(1)}

It is a scalar quantity as it only has magnitude and no direction.

Given is a motor bike travels 240 km ins 4 hours.

We can calculate the speed of the bike as -

s = 240/4 = 60 Km/hr

Then, the time taken to cover 450 Km will be -

t = 450/60

t = 7.5 hours

Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

Answer:

because the graphs of the two equations overlap each other

Step-by-step explanation:

when two graphs have the same line, the line overlaps so it looks like only one line. therefore, the answer is

C) because the graphs of the two equations overlap each other.

Answer:

Finding the degree of a polynomial is really simple. All you have to do is find the largest exponent in the polynomial, so in this case, the degree is 5 (Yes, my previous answer is wrong) and not 26. I don't know how you got 26.

Another example: In 3x² - 8x⁷ + 6xy⁴, the degree is 7.

Step-by-step explanation:

Step-by-step explanation:

To find the Slope of each line, pick two points you can clearly identify on each graph. The first graph has a point (-5,5) and (4,-5). Using these two points find the difference of the y coordinates divided by the difference in the x coordinates, like this:

5 - (-5). = 10

-5 - 4 = - 9

So the Slope is - 10/9

Same steps for all. Your equation is

(y1 - y2) / (x1 - x2)

Answer: They are both correct

Step-by-step explanation:

Jane saying 5 is a factor for every while number that has a 5 in the ones place is correct. For example, in the number 345 or 25, we can see that we have 5 in the ones place and 5 is a common factor for the numbers.

Also, Fred saying 5 is a factor for every while number that has a 0 in the ones place is correct as well. For example, the numbers 10, 20, and 200 all have 0 in their ones place and they have a factor of 5 as well.

Therefore, both of them are correct.

Answer:

0 = 0

Step-by-step explanation:

Q= -3(x + 4)+5x = 3(-2x-4)+8x

first : -3 multiply both x and 4 and 3 multiply both -2x and -4

then : -3x-12+5x = -6x-12+8x

and then collect like terms ; -3x+5x -12= -6x+8x-12

= 2x -12 = 2x-12

finally, 2x-2x = -12+12

0 = 0

Answer:

3/4

Step-by-step explanation:

We first need to have these two as a common denominator.

We can multiply 3 by 4 to get 12 as our denominator, which matches both denominators.

5/12 + 1*4/3*4 =

5/12 + 4/12 =

(5+4)/12 =

9/12

We can simplify further by diving by 3, which would give us 3/4.

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

Let's say that the number is x. Hedi adds 5 to the number, then multiplies its sum by -2. The result is 6. Writing this out as an equation:

[tex]-2(x+5)=6[/tex]

So now we solve for x. First, we divide both sides by -2, giving us:

[tex]x+5 = -3[/tex]

Then, to finish the problem, we subtract 5 from both sides:

[tex]x=-8[/tex]

Thus, the number Hedi started with was -8
