Answer:
The age of Jamal is 8 years.
And the age of his father is 32 years.
Step-by-step explanation:
=> let the age of Jamal be x and his father's age be y
=> so , A.T.Q ,
x+y = 40....i)
Find the value of y from here , that's y = 40-x .....
Now, After 4 years ,
=> 3(x+4) = (y+4)
=> 3x+12 = y+4
=> 3x+8 = y ...ii)
putting the value of y in equation ii)
=> 3x+8 = 40-x
=> 3x+x = 40-8
=> 4x = 32
=> x = 8
now ,
=> y = 40-x
=> y = 40-8
=> 32

The equation of a line is y + 4 = 6x + 13 What is the value of y at the point where the line crosses the y-axis?
Answer:
The given equation of line is
[tex] \rm \: y + 4 = 6x + 13[/tex]
This equation further can be written as
[tex] \qquad \sf \longrightarrow \:y = 6x + 13 - 4 \\ \\ \\ \qquad \sf \longrightarrow \: y = 6x + 9 - - - - (i)[/tex]
General line formula in the form can be written as
[tex]\qquad \sf \longrightarrow \:y \: = mx + b - - - - (ii)[/tex]
Point where this equation of line crosses the y-axis is
[tex]\qquad \sf \longrightarrow \:(0,b)[/tex]
On comparing the equation (i) and (ii) we obtain
[tex]\qquad \sf \longrightarrow \:(0,9)[/tex]

A rectangle has a length of 3x-5 and a width of 2x+9.
a. Write an expression for the perimeter of the rectangle.
b. Write an expression for the area of the rectangle.
Step-by-step explanation:
l = 3x - 5
w = 2x + 9
perimeter = 2l + 2w = 2(3x - 5) + 2(2x + 9) =
= 6x - 10 + 4x + 18 = 10x + 8
area = l×w = (3x - 5)(2x + 9) = 6x² + 27x - 10x - 45 =
= 6x² + 17x - 45

Solution :-
[tex]9m + 2 - (3m + 8) \\ 9m + 2 - 3m - 8 \\ m(9 - 3) + (2 - 8) \\ 6m - 6[/tex]
Answer:
6m - 6
Step-by-step explanation:
9m + 2 - (3m + 8) = 9m + 2 -3m -8
= 9m - 3m + 2 - 8
= 6m - 6
when you open the brackets, -(+3m) = -3m because when a positive sign times a negative sign, you get a negative sign. so, same thing for -(+8) = -8

Step-by-step explanation:
the perimeter of an isosceles triangle with equal side of length 4cm and third side of length 6cm will be
Answer:
14 cm
Step-by-step explanation:
1. Recognize that an isosceles triangle will have at least two equal sides. Given the wording of the problem, we can say that we have two equal sides of 4 cm and a third side of 6 cm
2. Define perimeter. The perimeter of a triangle is the length of the continuous line outlining the triangle
3. Add all three side lengths together (4 cm + 4 cm + 6 cm). This will equal 14 cm
please help i am very stressed :(
Step-by-step explanation:
The First part is correct.
The domain is All set of inputs of a function.
We know that tangent has a period of 180.
Since our interval has a distance of 180, and tan 0 isn't 1 over root of 3, we will have only 1 domain.
So let solve the solution.
[tex] \tan(x) = \frac{1}{ \sqrt{3} } [/tex]
[tex]x = \tan {}^{ - 1} ( \frac{1}{ \sqrt{3} } ) [/tex]
30°
[tex]x = 30°[/tex]
So the domain of this function is [30°].
Part C: Tangent has a period of 180 degrees, so our solution will occur every 180 degrees.
We want full revolutions, so let use a variable, let say n to represent a interger.
Part C: The general solution is
30°+(180n)°, where n is a interger( 1,2,3.....)
Part D: The answer of tan x=1/sqr root of 3 is , in degrees, of
x∈N, 30+180n, where n is a interger.

Suppose you owe 10 dollars to a friend. Each week you pay your friend at least 1 dollar back. Sometimes however you might pay your friend back 2 dollars in a week and other times you might pay your friend 5 dollars in a week. How many different payment sequences are possible
Answer: if you give your friend one dollar the first week you’d only owe 9 dollars left. Then the second week you play the 2 dollars, you now only owe 7 dollars. The third week comes and you give them 5, you only owe 2 dollars. Then you’d only be able to give them 2 dollars the next week, or one dollar then another one the following week. There are 4,5 different payment sequences possible.

How do I put this into slope-intercept form???
If you can please show your work!
Answer:
[tex]\mathrm{slope\:intercept\:form:\:y = \dfrac{ 1 }{ 2 } x+4}[/tex]
Step-by-step explanation:
To change the equation into slope-intercept form, we write it in the form y=mx+b
So this means that we have to solve for "y" in the equation "-x + 2y = 8"
−x + 2y = 8
Step 1: Add x to both sides
2y = 8 + x
Step 2: Now the equation is in standard form
2y = x + 8
Step 3: Divide both sides by 2
[tex]\mathrm{\dfrac{ 2y }{ 2 } = \dfrac{ x+8 }{ 2 }}[/tex]
Step 4: Dividing by 2 undoes the multiplication by 2
[tex]\mathrm{y = \dfrac{ 1 }{ 2 } x+4}[/tex]
The question:"Write an expression that has two terms.The expression should have a variable and a constant. Help :')
Answer: Quite simply: 2+x
A constant is simply a number, something that does not change: here it's "2"
A variable can change: here it's "x" - anything can be substituted for x
If we put those two together with a "+" sign, we get an expression: variables or constants (including multiple ones: such as 2x, which is a term) added to each other or subtracted from each other
mary has 30 nickels and dimes totaling $2.40. how many of each does she have?
Answer:
Nickels; 5 cents
Dimes; 10 cents
Given that she has 30 nickels:
30(nickels) x 5(a single nickel) = $1.50
2.40 - 1.50 = $0.90, those 90 cents leftovers should then be divided by 10 cents because one dime contains 10 cents and you want to figure out how many dimes there are:
90/10 = there are 9 dimes

Can someone please help me with number 6?
Step-by-step explanation:
substitute a with 2 and b with 3
2x+3
because it's the same equation it should just be an equal sign.
Answer:
Simplifying
ax + b = 2x + 3
Reorder the terms:
ax + b = 3 + 2x
Solving
ax + b = 3 + 2x
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-1b' to each side of the equation.
ax + b + -1b = 3 + -1b + 2x
Combine like terms: b + -1b = 0
ax + 0 = 3 + -1b + 2x
ax = 3 + -1b + 2x
Divide each side by 'x'.
a = 3x-1 + -1bx-1 + 2
Simplifying
a = 3x-1 + -1bx-1 + 2
Reorder the terms:
a = 2 + -1bx-1 + 3x-1
