A father is 28 years older than his daughter. In six years' time, he will be three times her age. Find their present ages.
Please use an algebraic equation to find the answer and show your working out if possible!!
Answer:
8 and 36
Step-by-step explanation:
let the daughter's age be x then father is x + 28
In 6 years their ages are
x + 6 and x + 28 + 6 = x + 34
Father is 3 times her age , then equation is
x + 34 = 3(x + 6) ← distribute
x + 34 = 3x + 18 ( subtract x from both sides )
34 = 2x + 18 ( subtract 18 from both sides )
16 = 2x ( divide both sides by 2 )
8 = x
Daughter's age is 8 and father's age is 8 + 28 = 36
write an equation of the line that passes through the given points (-6,3) (0,4)
Answer:
y=1/6x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-3)/(0-(-6))
m=1/(0+6)
m=1/6
y-y1=m(x-x1)
y-3=1/6(x-(-6)(
y-3=1/6(x+6)
y=1/6x+6/6+3
y=1/6x+1+3
y=1/6x+4

The cost of a pen and a pencil used to be the same, but recently the cost of the pen was increased by ₹4, whereas, the cost of pencil became ₹6 less than 5 times its original value. After the revised cost, if the pen was more expensive than the pencil, what could have been the possible original value of both the products, if the initial price was a natural number?
Answer:
The possible original values of both products are ₹2 or ₹1
Step-by-step explanation:
The question is a word problem leading to simultaneous equations
Let 'x' represent the initial value of the pen and pencil
Therefore;
The final cost of the pen = x + ₹4
The final cost of the pencil = 5·x - ₹6
x + ₹4 > 5·x - ₹6
∴ ₹4 + ₹6 > 5·x - x
₹10 > 4x
₹10/4 > x
₹2.5 > x
Given that x is a natural number, therefore
x ≤ ₹2
The possible original values of both products are ₹2 or ₹1
The possible original value of both products is ₹ 1 and ₹ 2.
The question is a word problem
Let x represent the initial cost of the pen and pencil since they were initially the same price.
When the costs of the pen was increased by ₹4, its new price is x' = x + 4.
Also, the cost of pencil became ₹6 less than 5 times its original value. So, the new price of the pencil is x" = 5x - 6.
After the revised cost, if the pen was more expensive than the pencil, then we have x' > x".
So, x + 4 > 5x - 6
x - 5x > - 4 - 6
-4x > - 10
x < -10/-4
x < 2.5
Since the initial price of the both products was a natural number, the two natural number less than 2.5 are 1 and 2.
So, the possible original value of both products is ₹ 1 and ₹ 2.

What is the area of the triangle of (-5,6),(1,3),(-5,-3)
Answer :
Hey there! I'm happy to help!
To find the area of a triangle you multiply the base by the height.
We see that our base is 5 units long because it stretches from -6 to -1 on the coordinate plane. Our height is 8 because the y value goes from 3 to -5.
To find the area of a triangle, you just multiply the base by the height then divide by 2.
5(8)=40
40/2=20
The area is 20 square units.
Have a wonderful day! :D
Is This What You Triangle Looks Like?
A line has a slope of 1 and passes through the point (2,4).
Answer:
y=x+2
Step-by-step explanation:
if you are looking for the equation, you can use point-slope formula because you are given the slope and a point that runs through the line. so...
(y-y1) = m (x-x1)
(y-4) = 1(x-2)
solve and add 4 onto both sides and multiply 1 by (x-2) which equals itself and then ad -2+4 to get 2

Water flows from a tank with a rectangular base measuring 80cm by 70cm into another tank with a squarebase of side 60cm. If the water in the first tank is 45cm deep , how deep will it be in the second tank.
Answer:
70cm
Step-by-step explanation:
,
Since, both of the tank posses the same quantity of water then there volume is the same thing
For rectangular base
Volume= (Lenght × breadth × hheight)
If we substitute values
Lenght= 80 cm
Breadth= 70 cm
height= 45 cm
Volume= 80cm × 70cm × 45cm
Volume= 252000cm^3
For square base
Volume= (side)^2 × height
side =60cm.
But volume of square base= volume of
rectangular base
252000cm^3= 60^2 × height
Height= (252000cm^3)/(60^2 )
Height= 70 cm
Hence, the second tank is 70 cm deep

The length of a rectangle is 10 centimeters less than its width. What are the dimensions of the rectangle if its area is 171 square centimeters?
Step-by-step explanation:
let the width = y
the length =y-10
area of rectangle=length ×breadth
171 =y-10×y
171=y^2-10y
it turns into quadratic equation
y^2-10y+171=0
cant be solved by factorization therefore use general formula
y=-b+or-√(b^2-4ab)/2a
a=1 (coefficient of y^2) ,b=-10 , c=171
y=--10+or-√{10^2-4(1)(10)}\2(1)
y=10+or-√{100-40}\2
y=10+or-√60/2
y=10+or-(7.74/2)
y=10+3.87
y=13.87cm
OR
y=10-3.87
y=6.13cm
if y=13.87 then width is 13.87&length is 13.87-10
=3.87
OR
if y=6.13 then width is 6.13&length is 6.13-10=-3.87
Graph: y = (x+3)²- 4
x-int=-5, y-int=5 and vertex is at (-3,-3)
