Answer:
rearrange the question
y - 5x = 8.................(1)
y - 8x = 9..................(2)
make y the subject formula in eqn. (1)
y = 8 + 5x................(3)
substitute
8 + 5x - 8x = 9
-3x = 1
x = -⅓
y = 8 + 5x
y = 8 + (-⅓)
y = 23/3

This circle is centered at the origin, and the length of its radius is 5. What is the equation of the circle?
Given :-
Circle's centre is at origin.The radius is 5 u .To Find :-
The equation of the circle .Answer :-
As we know that the general equation of circle centred at origin is ,
x² + y² = r²where r is the radius .Here r =5 , So ,
x² + y² = 5²x² + y² = 25Solve for m: m=−(4+m)+2
Answer:
m = - 1
Step-by-step explanation:
m = -4 - m + 2 Combine
m = -2 - m Add m to both sides
m+m = - 2 Combine
2m = - 2 Divide by 2
m = -2/2
m = - 1
m=−(4+m)+2
Simplify both sides of the equation.
m=−(4+m)+2
m=−m+−4+2
m=(−m)+(−4+2)
m=−m+−2
m=−m−2
Add m to both sides.
m+m=−m−2+m
2m=−2
Divide both sides by 2.
2m/2=−2/2
m=−1

Which relation is a function?
Answer: see below
Step-by-step explanation:
Vertical line test determines which graph is a function.
The graph should pass the vertical line only once if it’s a function.
So we can see that it is the left V-shaped graph.

The graph number [2], represents a function.
What is a expression? What is a mathematical equation? What is Equation modelling ?A mathematical function is made up of terms (constants and variables) separated by mathematical operators having a dependent and independent variable. A mathematical equation is used to equate two expressions. For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which y exists.
We have some graphs of relations as shown.
Only the graph number [2], represents a function as for a single value value of [x], a single unique value of [y] exists.
Therefore, the graph number [2], represents a function.

PLEASE ANWSER CORRECTLY!! I WILL MARK BRAINIEST!!
Answer:
A) 33
B) 58
Step-by-step explanation:
A is 33 because supplementary angles add up to 180 in total. 180 - 147 = 33, so its supplementary angle would be 33 degrees.
B is 58 because complementary angles add up to 90 in total. 90 - 32 = 58, so the complementary angle would be 58 degrees.
Answer: 33° and 58°
Step-by-step explanation:
147° and 32°
Two angles are called complementary when their measures add to 90 degrees. (90° - 32°) = 58°
Two angles are called supplementary when their measures add up to 180 degrees. (180°-147°) = 33°

Answer:
73.33
Step-by-step explanation:
share out £20 between bill and sue in the ratio 3:2
Answer:
12:8
Step-by-step explanation:
Bill receives £12, and Sue receives £8.
In order to divide £20 between Bill and Sue in the ratio 3:2, we first need to find the total number of parts in the ratio. The sum of the parts in a 3:2 ratio is 3 + 2 = 5.
Next, we determine the value of one part by dividing the total amount (£20) by the total number of parts (5): £20 ÷ 5 = £4.
Now, we can allocate the money to Bill and Sue according to their shares in the ratio. For Bill, who gets 3 parts, we multiply his share of one part (£4) by 3: £4 × 3 = £12. For Sue, who gets 2 parts, we multiply her share of one part (£4) by 2: £4 × 2 = £8.
Thus, Bill receives £12, and Sue receives £8.
In mathematical terms, we can represent the division of £20 between Bill (B) and Sue (S) as follows:
Let the ratio be represented as B:S = 3:2.
Total parts in the ratio = 3 + 2 = 5.
Value of one part (Vp) = Total amount / Total parts = £20 ÷ 5 = £4.
Amount received by Bill (Ab) = 3 parts × Vp = 3 × £4 = £12.
Amount received by Sue (As) = 2 parts × Vp = 2 × £4 = £8.
Thus, Bill receives £12, and Sue receives £8.
In summary, when dividing £20 between Bill and Sue in the ratio 3:2, we follow the steps of finding the total parts in the ratio, calculating the value of one part, and then distributing the amount based on each individual's share in the ratio.
