<h2>Answer with explanation:</h2>

The given system of equations :

x - y = 1-------(1)\\\\-2x + 2y = 5-------(2)

To plot the given equations of xy plane, we first consider equation (1)

x - y = 1

Now, we put some random values of x and note the y values on them

At x= 0  , 0 - y = 1\Rightarrow\ y=-1

At x= 1  , 1 - y = 1\Rightarrow\ y=1-1=0

i.e. points to plot equation (1) = (0,-1) and (1,0).

Now, consider equation (2),

At x= 0  , - 2(0)+ 2y = 5\Rightarrow\ y=\dfrac{5}{2}=2.5

At x= 1  , -2(1)+2 y = 5\Rightarrow\ 2y=5+2\Rightarrow\ y=\dfrac{7}{2}=3.5

i.e. points to plot equation (2) = (0,2.5) and (1,3.5).

Now, we plot the equation as given below, we can see that the lines are parallel lines , also the parallel lines has no intersecting point, it means it has NO SOLUTION.

I don't understand what question b) i) is asking me to do?
Sonja [21]

Answer:

32

Step-by-step explanation:

Imagine someone is trying to put tiles on a bathroom floor - this is the situation in this question. "tiles needed to fit across the length" is asking how many 25cm tiles can fit in the length of the bathroom, which is 8m.

To do this, we need to do some conversion.

8m to cm = 800cm

800 ÷ 25 = 32

This means 32 tiles are needed to fit across the length of the bathroom floor.

Hope this makes sense!

Converges or diverges, find the sum. 3 -3/4 +3/16 -3/64.
Gnesinka [82]
We know the terms in this geometric sequence are 3, -3/4, 3/16 and so on.

now.. what's the "r" or common ratio?  well, in a geometric sequence, to get the next term's value you multiply by "r", therefore, if you divide any of those values, by the value before it, the quotient will be, yes, you guessed it, "r".

namely say a, a*b.... now (a*b)/a is just b, the quotient is the value you used as multiplier.

\bf -\cfrac{3}{4}\div 3\implies -\cfrac{3}{4}\div \cfrac{3}{1}\implies -\cfrac{3}{4}\cdot \cfrac{1}{3}\implies -\cfrac{1}{4}

any other two pair of values will spit out the same "r".

now, the Sum of a geometric sequence reaches a limit or point, that is converges, only if the value of "r" is a fraction and more than -1 or less than 1, negative or positive.

or in short, if | r | < 1.

now, in this case, -1/4 is indeed more than -1 and less than 0, therefore, the Sum of the sequence is convergent, it meets at a limit.
