Step-by-step explanatio -3/8d-1 3/8
The expression "quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity" or (-3 1/4d + 3/5) - (2 7/8d + 7/10) is equivalent to "negative forty nine over 8 times d minus one tenth" or -49/8d - 1/10.
An algebraic expression is a number, variable, or the combination of both and operational symbols.
To determine the equivalent of the expression "quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity" or simply (-3 1/4d + 3/5) - (2 7/8d + 7/10), combine all like terms and perform the necessary operations.
(-3 1/4d + 3/5) - (2 7/8d + 7/10)
⇒ -3 1/4d + 3/5 - 2 7/8d - 7/10
⇒ (-3 1/4 - 2 7/8)d + 3/5 - 7/10
⇒ (-13/4 - 23/8)d + 6/10 - 7/10
⇒ (-26/8 - 23/8)d - 1/10
⇒ -49/8 d - 1/10
Hence, the equivalent expression is "negative forty nine over 8 times d minus one tenth" or -49/8d - 1/10.

Write the function rule for each function reflected in the given axis.
f(x)=2 x-4 ; x - axis
The given function is f(x) = 2x-4,
We have to find the equation where the reflection of this function is over the x-axis.
There are two types of reflections in general when we talk about functions;
One reflection is over the x-axisThe other is over the y-axis.Now we take an example that we are provided with a point with coordinates (x, y). If we want to reflect it over the x-axis, then the coordinates of this point will become (x, -y). This is because the values of y are negative when we move above the x-axis and positive when we move below the x-axis and vice versa.
The equation to show this is: y = -f(x).
We multiply the entire function, f(x), to find it by a negative. Since f(x) = 2x-4, the transformed function is f(x) = -2x+4.
Therefore, the function rule for the function shown is -f(x).

Evaluate the indefinite integral by using the given substitution to reduce the integral to standard form.
The indefinite integral, [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{-1}{9} cos(9x) + C[/tex]
We have to find the indefinite integral,
[tex]\int {sin(9x)} \, dx[/tex]
using the substitution 9x = u.
So we need to change the variable of integration from x to u using this substitution.
9x = u ⇒ 9 dx = du
So [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{1}{9} \int{sin(u) \ du[/tex]
= 1/9 (- cos(u)) + C, [ Since integral of sin(u) = -cos(u) ]
where C is the integration constant which is often put when evaluating indefinite integrals.
Now replacing u with x to get the final answer,
1/9 (- cos(u)) + C = -1/9 cos(9x) + C
Therefore, [tex]\int {sin(9x)} \, dx[/tex] = [tex]\frac{-1}{9} cos(9x) + C[/tex]

because

over = 3x
4
we can put everything in parentheses and multiply by 4
2x - 10
4( over )= (3x) 4
4
The 4's on the left side will cancel out around and leave
2x - 10
on the right we multiply 3x x 4 which equals 12x
rewrite the equation
2x - 10 = 12x
subtract 2x on each side with the variable.
2x - 10 = 12x
-2x -2x
the 2x's on the left will cancel out.
on the right 12x - 2x equals 10x
now the equation is
-10=10x
but we are not done
divide 10 on each side
on the left -10/ 10 equals -1 because one number is negative and that does not give a postive result.
on the right 10x/ 10 the 10's cancel out leaving the varible x

What is coordinates ?
Coordinates are a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane. The x axis (horizontal) and y axis are the two axes that make up a coordinate plane (vertical).The formulae for finding the new coordinates are given by
x' = x cosθ - y sinθ
y' = x sinθ + y cosθ
Substituting θ = 270
x' = x cos270° - ysin270° = x(0) - y( -1) = y
y' = x sin270° + y cos270° = x(-1) + y( 0) = x
New coordinates are ( y , -x)

What is termed as the inequality?The term inequality refers to a mathematical equation wherein the sides are not equal. An inequality equates any two values and shows that one is less, greater, or equal to the value on either side of the equation.
Rule 1: When inequalities are connected, they can be crossed. As a result, if an is greater than b and b is greater than c, a will be greater than c as well.Rule 2: When you swap the values, the sign as well reverses.Rule 3: An inequality can be either > or, but not both at the same time.Rule 4: Reversing the sign by multiplying both sides of the inequality by the a negative sign.Consider the given expression;
38 ≤ bx + 8
Simplify the equation;
38 - 8 ≤ bx
