Answer:
For train A, the distance traveled as a function of time in hours is written as:
y = 68*x
For train B, we know that it's equation passes through the points (0, 0) and (1, 64)
Remember that:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then the slope for the equation of train B is:
a = (64 - 0)/(1 - 0) = 64
Then equation of train B is something like:
y = 64*x + b
Now, we know that it passes through the point (0, 0), this means that when x = 0, we also have y = 0, then if we replace these two values in the equation we get:
0 = 64*0 + b
0 = 0 +b
then b = 0
This means that the equation for train B is:
y = 64*x
Where again, y is the distance in miles and x is the time in hours.
If we look at both equations, we can see that train A has a larger slope, which means that for each unit of time, train A travels a larger distance, then we can conclude that train A is faster than train B.

(43×8) - (234÷6)
Answer:
305
Step-by-step explanation:
43*8=344
234/6=39
344-39=305
Since the equation is [tex](43\times 8) - (234\div 6)[/tex] so after solving it, the answer is to be considered as the 305.
Calculation of the equation:Since the equation is [tex](43\times 8) - (234\div 6)[/tex]
So,
we have to solve it
= 344 - 39
= 305
Hence, Since the equation is [tex](43\times 8) - (234\div 6)[/tex] so after solving it, the answer is to be considered as the 305.

If y varies directly as x, and y is 18 when x is 5, which expression can be used to find the value of y when x is 11?
Oy- (11
y (11)
(18)(5)
oy-
5
11
2 y = (1865
Answer:
y = 18/5(11)
Step-by-step explanation:
If y varies directly as x, this is expressed as;
y∝x
y = kx
k is the constant of proportional constant
if y = 18 and x = 5
18 = 5k
k = 18/5
to get the expression that can be used to find the value of y when x is 11
y = kx
y = 18/5(11)
This gives the required expression

The floor area of a rectangular room is represented by x2 + 3xy – 10y2. What could the length and width be?
Answer:
The length is x + 5y
The width is x - 2y
But see below.
Step-by-step explanation:
Remark
The point of this question is to factor the trinomial. It can be factored.
(x 5y)(x 2y )
has to be the beginning of the factoring process.
(x - 5y)(x + 2y) The signs are right. The factoring isn't. The middle term has to be plus.
(x + 5y)(x - 2y)
The length is x + 5y
The width is x - 2y
x must be larger than 2y, otherwise you will get a negative width. That cannot be right.
a jewellery shop is having a sale
a bracelet is now reduced to 420 pounds
this is 70% of the original price
A) workout the original price of the bracelet
a ring is now reduced to 840 pounds
this is a saving of 40% of the original price
b) workout the original price of the ring
Answer:
a) £600
b) £1400
Step-by-step explanation:
a)
original price = x
reduced price = £420
reduced price is 70% of original price
Since the discounted price, £420, is 70% of the original price, x, then
70% of x = 420
0.7x = 420
x = 420/0.7
x = 600
Answer: £600
b)
original price = x
discounted price = £840
discount percentage = 40%
The original price is x, and x is 100% of the original price since 100% is the whole amount. The discount is 40% of the original price. 100% - 40% = 60%. That means the discounted price is 60% of the original price.
60% of x = 840
0.6x = 840
x = 840/0.6
x = 1400
Answer: £1400

Step-by-step explanation:
y=x^2-x+1 1. Write out the equation
y=y^2-y+1 2. Substitute the "x"s for "y"s
0=y^2-2y+1 3. Subtract "y" from both sides of the equation
0=(y-1)(y-1) 4. Factor into a binomial
y-1=0
y=1
x=1
