The value of the expression for x=8 is 24
What are like and unlike terms in an expression?In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions
Given here: The expression as 7a-4a
Now combining the like terms we get
7a-4a=3a
for a=8
we have
3a=3×8
=24
Hence, The value of the expression for x=8 is 24

Answers
Answer:
I dont know But maybe the answer is No
Step-by-step explanation:
0.3 is 30% and if 1/10 is 10% then 2/20 must be 10% because 5% is 1/20
so maybe 3/20 is only 15%

Answer:
2
Step-by-step explanation:
Simplify the following:
(-6 - 4)/(-5)
Hint: | Group the negative terms in -6 - 4 together and factor out the minus sign.
-6 - 4 = -(6 + 4):
(-(6 + 4))/(-5)
Hint: | Evaluate 6 + 4.
6 + 4 = 10:
(-10)/(-5)
Hint: | In (-10)/(-5), the numbers 10 in the numerator and -5 in the denominator have gcd greater than one.
The gcd of 10 and -5 is 5, so (-10)/(-5) = (-(5×2))/(5 (-1)) = 5/5×(-2)/(-1) = (-2)/(-1):
(-2)/(-1)
Hint: | Cancel common terms in the numerator and denominator of (-2)/(-1).

The equivalent value of the fraction is A = 2
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the numerator of the fraction be p
Let the denominator of the fraction be p
Now , A = p/q
when the value of p = ( -6 - 4 )
And , when the value of q = ( -5 )
On simplifying the equation , we get
A = ( -6 - 4 ) / ( -5 )
So , the left hand side of the equation is equated to the right hand side by the value of ( -6 - 4 ) / ( -5 )
A = ( -6 - 4 ) / ( -5 )
A = ( -10 ) / ( -5 )
On simplifying , we get
Divide by -1 on both numerator and the denominator , we get
A = 10/5
A = 2
Therefore , the value of A = 2
Hence , the fraction is A = 2

What is the slope of the line that passes through the points (5, -4)(5,−4) and (7, -4) ?(7,−4)? Write your answer in simplest form.
Answers
Answer:
the slope is 0, m=0
Step-by-step explanation:
do the equation y2 - y1 over x2 - x1
Equation of a line is the y = 3x - 1 is with a slope of 3 and a passing point of (2, 5).
What is meant by slope?An angled surface, especially a hill or mountain, or the angle at which something rises: On flat terrain, students develop their directional skiing skills.A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes.The ratio of the difference between the y- and x-coordinates of the two points that make up the line must be calculated. The slope of the line is the value that is obtained. It displays how the line's y-axis rise compares to its x-axis run.Here, slope of line equals 3.
Passing the buck (2, 5)
line equation
(y - y₁) = m (x - x₁)
y - 5 = 3 (x - 2) (x - 2)
y - 5 = 3x - 6
y = 3x - 6 + 5
y = 3x - 1
So, the equation of the line traversing the points (2, 5) and having a slope of 3 is y = 3x - 1.
The complete question is : A line with a slope of 3 passes through the point (2, 5). Write an equation for this line in point-slope form.

X is the independent variable that represents the independent variable of the function.
What are independent and dependent variables?Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.
If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.
We are given an expression as y=1/2x-2

First you learned (back in grammar school) that you can add, subtract, multiply, and divide numbers. Then you learned that you can add, subtract, multiply, and divide polynomials. Now you will learn that you can also add, subtract, multiply, and divide functions. Performing these operations on functions is no more complicated than the notation itself. For instance, when they give you the formulas for two functions and tell you to find the sum, all they're telling you to do is add the two formulas.

Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).
To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.
(f + g)(x) = f (x) + g(x)
= [3x + 2] + [4 – 5x]

(f – g)(x) = f (x) – g(x)
= [3x + 2] – [4 – 5x]
= 3x + 2 – 4 + 5x
= 3x + 5x + 2 – 4
= 8x – 2
(f × g)(x) = [f (x)][g(x)]

The entry tickets at a community fair cost $5 for children and $10 for adults. On a certain day 1000 people entered in the fair and $7,100 is collected. How many adults and how many children were at the fair?
Answers
Answer:
C = 580 children.
A = 420 adult.
Step-by-step explanation:
Let the number of children be C.
Let the number of adult be A.
Translating the word problem into an algebraic equation, we have;
A + C = 1000 .......equation 1
10A + 5C = 7100 .......equation 2
A = 1000 - C .......equation 3
Substituting eqn 3 into eqn 2, we have;
10(1000 - C) + 5C = 7100
10000 - 10C + 5C = 7100
10000 - 7100 = 10C - 5C
2900 = 5C
C = 2900/5
C = 580 children.
Now, to find the value of A.
From equation 3;
A = 1000 - C
A = 1000 - 580
A = 420 adult.
