Answer:
£503.75
Step-by-step explanation:
he negotiated a 7% decrease on a £6500:
the price of the car after discount is : 6500-(6500*7%) = £ 6045
£6045 paid fully in 12 month: £ 6045/12= £503.75
Which relation is a function of x?
Answer: The bottom option, the graph.
Step-by-step explanation:
A relation is something that gets input from a set, called domain (usually the x) and "transforms" them into an output, from a set called the range.
Now, a relation is only a function if, for all the elements x in the domain, each one of them has only one element y in the range associated to it.
For example, in the first set we can see that the value x = 1 appears two times, it is related to different values in the range, then this is not a function.
The second relation is not a function.
the third relation is:
x = 3*y^2 - 7
This is a function, but in this relation x is the output and y the input, so this is a function of y.
In the fourth relation we can see a graph, this is a function (each value in the domain is related to only one in the range), and in the horizontal axis we can see a x, so this is a function of x.

A gear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket. If a bike has 36 teeth on the front sprocket and 12 teeth on the rear sprocket, what is the gear ratio for the bike? Also totally math unrelated, but how do you add friends, or send a friend request?
Answer:
36:12. 36 is the teeth on the front socket and 12 is the teeth on the rear socket. All you need to do is simplify by finding the greatest common factor (GCF) of 36 and 12-which is 12, then divide by the GCF. This gives you 3:1. The gear ratio for the bike is 3 teeth on the front socket for every 1 teeth on the rear socket (3:1)
If you want to add friends on brainly click their profile picture you will see send friend request click on it and then boom you are friends with that person but you have to wait until the person add you back.
Step-by-step explanation:
Mark me as brainliest
The ratio would start as 36:12
The front number (36) can be divided by the back number (12)
The 36:12 can be reduced to 3:1
The ratio is 3:1

)
B. x= -15+4
O C. x= -15-4
D. x= V5 + 4
E. x= -111-4
OF. x= V5 - 4
Answer:
x² - 8x+ 16 = 5
x² - 8x + 16 - 5 = 0
x² - 8x + 11 = 0
Using the quadratic formula
x = -b±√b² - 4ac / 2a
a = 1 , b = - 8 c = 11
x = --8±√(-8)² - 4(1)(11) / 2(1)
x = 8 ± √ 64 - 44 / 2
x = 8±√20 / 2
x = 8 - √ 20 / 2 or x = 8 + √ 20 / 2
x = - √ 5 + 4 or x = √5 + 4

Please help!! Maths question I don't understand!
Answer:
see explanation
Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v = [tex]\frac{k}{w}[/tex] ← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 = [tex]\frac{k}{5}[/tex] ( multiply both sides by 5 )
45 = k
v = [tex]\frac{45}{w}[/tex] ← equation of proportion
When w = 4 , then
v = [tex]\frac{45}{4}[/tex] = 11.25

y is directly proportional to x when y=30, x=6 a) work out an equation connecting y and x b) work out the value when x=12
Answer:
a) y = 5x
b) y = 60
Step-by-step explanation:
a) Standard equation of direct proportion:
y = kx
We need to find k. We can use the given values of x and y to find k.
x = 6; y = 30
30 = k * 6
k = 30/6 = 5
Now we use k = 5 in the standard equation to get this problem's direct proportion equation.
y = 5x
b)
x = 12
y = 5x
y = 5 (12)
y = 60

What is the equation of the following line written in slope-intercept form? Oy=-3/2x-9/2
Oy=-2/3x+9/2
Oy=3/2x-9/2
Answer:
y = -3/2x-9/2
Step-by-step explanation:
We have two points ( -3,0) and (-1,3)
The slope is
m = (y2-y1)/(x2-x1)
= (-3-0)/(-1- -3)
= (-3-0)/(-1+3)
= -3/2
Using slope intercept form
y = mx+b where m is the slope and b is the y intercept
y =-3/2x+b
Using the point (-3,0)
0 = -3/2(-3) +b
0 = 9/2+b
b = -9/2
y = -3/2x-9/2

The function shown in graph (A) has a constant additive rate of change is -1/4 option (A) is correct.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
As we know,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the first graph:
The line goes through the points:
(-2, 2) and (2, 1)
y - 1 = (1-2)/(2+2)[x -2]
y - 1 = (-1/4)[x -2]
y = -x/4 + 1/2 + 1
y = -x/4 + 3/2
The constant additive rate of change = -1/4
Thus, the function shown in graph (A) has a constant additive rate of change is -1/4 option (A) is correct.

Working out simultaneous equations.
Answer:
x = 6/5
y = 8/5
Step-by-step explanation:
3x - y = 2
2x + y = 4
Add the equations, cancelling y.
5x = 6
x = 6/5
Put x as 6/5 in the second equation and solve for y.
2(6/5) + y = 4
12/5 + y = 4
y = 4 - 12/5
y = 8/5

Any number less than .5 rounds down, any number greater to or equal to 0.5 rounds up, so if you have 3.5 or higher it rounds to 4
The y-intercept of the graph of a line is located at (0, –2). The line also passes through the point (5, 1).
Answer:
y - 1 = (3/5)x
Step-by-step explanation:
First find the slope of this line. As we move from (0, -2) to (5, 1), x (the 'run') increases by 5 and y (the 'rise') increases by 3. Thus, the slope of this line is m = rise / run = 3/5.
Using the point-slope formula for the equation of a straight line:
y - 1 = (3/5)(x - 5), or
y - 1 = (3/5)x This can also be written as 5y - 5 = 3x, or
y = (3/5)x + 1

What are the excluded values?
Answer:
y = 0
z = 5
Step-by-step explanation:
Since you cannot have a zero in the denominator (divide by 0 or undefined error), you have to exclude values that can turn the bottom into a zero. If you plug in 0 for y, you would get an error, and if you plugged in z for 5, you would get another error because you would be multiplying 0 in the denominator, so those 2 values must be excluded.
good morning :) The rental car holds 25 gallons of gas and gets 18 miles per gallon. The trip to Yarrow City is 1350 miles. How many times will the car need to be filled up to make the trip? A. 2 B. 3 C. 4 D. 5
By taking the quotient between the total distance and the distance traveled with one tank, we conclude that the correct option is B.
How many times will the car need to be filled?
We know that the car holds 25 gallons, and gets 18 miles per gallon.
Then, with one tank, the distance that the car can travel is:
25*18mi = 450mi
The number of times that the tank must be filled is equal to the quotient between the total distance of the trip, and the distance traveled with one tank, it is:
1350mi/450mi = 3
This means that the tank must be filled 3 times, so the correct option is B.

the sum of the first 6 terms of a geometric series is 15624 and the common ratio is 5. what is the first term of the series?
Answer:
first term a=4
Step-by-step explanation:
Sum of the first 6 terms S6 = 15624
common ratio r= 5
n= 6
first term a=?
Formula: S6= a(r^n-1)/r-1
15624 = a( 5^6-1)/5-1
15624 = a(15625-1)/4
15624= a( 15624)÷4
15624= 15624a÷4
Cross multiply
15624×4 = 15624a
62496 = 15624a
divide both sides by 15624
62496÷15624 = 15624a÷15624
4 = a
a= 4

Answer:
18.84 meters.
Step-by-step explanation:
The formula for a circle is πr^2.
πr^2 = 28.26
3.14 * r^2 = 28.26
r^2 = 9
r = plus or minus 3.
But since this deals with the area of a circle, there is no way a radius can be negative. So, the radius is 3 meters.
The formula for the circumference is 2πr.
2 * 3.14 * 3 = 6 * 3.14 = 18.84.
So, the circumference of the circle is 18.84 meters.

Required angle measures 39°
Step-by-step explanation:
Let's say, x measures the angle between the hypotenuse and the common base of two triangles.
Sin(x) = 5/8
x = 39°
This angle is complementary to the angle other than theta (let's say y) in the required triangle.
90 - x = y and 90 - theta = y
>>> Theta = x
