Step(i)
Given that the system of equations
x-y = 6 ..(i)
y = 2x -5 ..(ii)
By using substitution method,
substitute y=2x-5 in equation (i) , we get
x -(2x-5) =6
x -2x+5 =6
-x = 6-5
-x =1
x=-1
Step(ii):-
Put x=-1 in equation (ii) , we get
y = 2(-1) -5 = -2-5 =-7

Graph: f(x) = 0.5^x- 3
Step 1: Calculate the initial value of the function.
f(0) =
The initial value of a function is the value of the function, when x = 0
The initial value of the function is -2.
The function is given as:
[tex]\mathbf{f(x) = 0.5^x - 3}[/tex]
To calculate the initial value, we simply substitute 0 for x.
So, we have:
[tex]\mathbf{f(0) = 0.5^0 - 3}[/tex]
Evaluate the exponents
[tex]\mathbf{f(0) = 1 - 3}[/tex]
Subtract 3 from 1
[tex]\mathbf{f(0) = - 2}[/tex]
Hence, the initial value of the function is -2.

f(x)=x^2+3x-5. find and simplify f(x+h)-f(x)
Answer:
[tex]f(x + h) - f(x) = h^2 + 3h - 5[/tex]
Step-by-step explanation:
Given
[tex]f(x) = x^2 + 3x - 5[/tex]
Required
Find f(x + h) - f(x)
In functions:
[tex]f(x + h) = f(x) + f(h)[/tex]
So:
[tex]f(x + h) - f(x) = f(x) + f(h) - f(x)[/tex]
Collect Like Terms
[tex]f(x + h) - f(x) = f(x) - f(x)+ f(h)[/tex]
[tex]f(x + h) - f(x) = f(h)[/tex]

At a football game, 43% of people attending were supporting the home team, while 57% were supporting the visiting team. If the total number of people attending the game was 4500, how many people attending were supporters of the home team?
Answer:
1935
Step-by-step explanation:
Trust me
There are 1,935 peoples attending were supporters of the home team.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The total number of people attending the game = 4500
At a football game, 43% of people attending were supporting the home team.
And, 57% were supporting the visiting team.
Now,
Since, The total number of people attending the game = 4500
Hence, Number of supporters of the home team = 43% of 4500
= 43/100 x 4500
= 1,935
Thus, There are 1,935 peoples attending were supporters of the home team.

Each circle counts as one whole, Write a mixed number giving the amount shaded. Then, write this amount as an improper fraction.
Answer:
[tex]2 \frac{2}{5} [/tex]
[tex] \frac{12}{5} [/tex]
Step-by-step explanation:
As a mixed fraction, There are 3 circles with 5 pieces in each so our denominator will be 5
The number that is shaded is 2 whole circles so that is 10 and 2 out of 5 of last one.
The whole number is 2 and the fraction for the last circle is 2/5 so our mixed number is
[tex]2 \frac{2}{5} [/tex]
Now to find the improper fraction turn 2 into a fraction with 5 as a denominator.
[tex] \frac{2}{1} \times \frac{5}{5} [/tex]
Which equal
[tex] \frac{10}{5} [/tex]
Then add 2/5 to 10/5
[tex] \frac{10}{5} + \frac{2}{5} = \frac{12}{5} [/tex]

There are 2 white chocolates for every plain chocolate in a box of chocolates.
There are no chocolates of any other colour in the box.
There are 10 plain chocolates in the box.
How many chocolates are there in the box altogether?
Answer:
The are 30 chocolates in the box.
Step-by-step explanation:
Since there are 2 white chocolates for every plain chocolate in a box of chocolates, and there are no chocolates of any other color in the box, and there are 10 plain chocolates in the box, to determine how many chocolates are there in the box altogether the following calculation must be performed:
10 + (2 x 10) + 0 = X
10 + 20 + 0 = X
30 = X
Therefore, there are 30 chocolates in the box.

==========================================================
Explanation:
Focus on triangle TRS. This triangle has congruent base angles as shown by the double arcs. This means that the sides opposite these angles (TR and RS) are congruent. So TR = RS.
Because RS = 11, this makes TR = 11 too.
Now move onto triangle UTR. This triangle is equilateral because each angle is the same measure (each angle being 60 degrees).
So UT and TR are the same length, and,
UT = TR
x-7 = 11
x-7+7 = 11+7
x = 18
--------------
Since every angle of triangle UTR is 60 degrees, this makes angle URT 60 degrees and angle TRS to be 180-60 = 120 degrees.
Move back to triangle TRS. We have these interior angles:
R = 120T = 5yS = 5yFor any triangle, the interior angles always add to 180
R+T+S = 180
120+5y+5y = 180
10y+120 = 180
10y = 180-120
10y = 60
y = 60/10
y = 6

Given :
segment AB = segment DEsegment BC = segment EFsegment AC = segment DFSince all sides are equal triangle ABC is congruent to triangle DEF under the SSS congruence criterion.
m∠B = (92+y)°
m∠E = (6y-28)°
We know that :
angle B = angle EWhich means :
[tex] = \tt92 + y = 6y - 28[/tex]
[tex] =\tt 92 = 6y - 28 - y[/tex]
[tex] =\tt 92 = 5y - 28[/tex]
[tex] = \tt92 + 28 = 5y[/tex]
[tex] = \tt120 = 5y[/tex]
[tex] =\tt y = \frac{120}{5} [/tex]
[tex] =\tt y = 24[/tex]
Thus, the value of y = 24
Then :
angle B :
[tex] =\tt 92 + y[/tex]
[tex] =\tt 92 + 24[/tex]
[tex] = \tt116[/tex]
Thus, the measure of angle B = 116
angle E :
[tex] = \tt6y - 28[/tex]
[tex] =\tt 6 \times 24 - 28[/tex]
[tex] =\tt 144 - 28[/tex]
[tex] =\tt 116[/tex]
Thus, the measure of angle E = 116
Since the measure of both these angles is equal we can conclude that we have found out their correct measures.
measure of segment AC = 2x + 47
Measure of segment DF = 6x + 3
Segment AC = Segment EFWhich means :
[tex] = \tt6x + 3 = 2x + 47[/tex]
[tex] = \tt6x + 3 - 2x = 47[/tex]
[tex] = \tt4x + 3 = 47[/tex]
[tex] \tt4x = 47 - 3 \\ 4x = 44[/tex]
[tex] =\tt x = \frac{44}{4} [/tex]
[tex] =\tt x = 11[/tex]
Thus, the value of x = 11
Let us check whether or not we have found out the correct value of x by placing 11 in the place of x :
[tex] = \tt6 \times 11 + 3 = 11 \times 2 + 47[/tex]
[tex] =\tt 66 + 3 = 22 + 47[/tex]
[tex] =\tt 69 = 69[/tex]
m∠B = 69°m∠C = 69°Therefore, the value of x = 11HELP PLSSSSSS
