The linear equation perpendicular to the line y = 1/2x - 4 is:
y = -2x + 25
How to find the linear function?A general linear equation can be written as:
y = m*x + b
Where m is the slope and b is the y-intercept.
And two lines are perpendicular if the product between the slopes is -1, then if we want to find a line perpendicular to:
y = 1/2x - 4
Then the slope m must be sch that:
m*(1/2) = -1
m = -2
Then the line is like:
y = -2*x + b
And we know that this passes through (10, 5), replacing these values:
5 = -2*10 + b
5 = -20 + b
5 + 20 = b
25 = b
So the linear equation is:
y = -2x + 25

The expression for the width is x (b) The perimeter of the rectangle in terms of x is x +8
What is perimeter?You should understand that the perimeter of a rectangle is the distance round the rectangle
The given parameters that will help us to understand and solve the question are
Length = 4 inwidth = xArea = 2x+24Area = length * width
This implies that 2x +24 =4x
Collecting like terms =4 = 4x-2x
2x = 24
Therefore x = 24/2 = 12
b) The perimeter is = L+W+L+W
Perimeter = 2L+w

Complete Question -
A city planner wants to build a road perpendicular to D Street. What should be the slope of the new road?
The slope of the new road is zero.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Take points from the Graph (5, 0) and (5, 4).
Slope of a line = m = tanθ
where θ is the angle made by the line with the x−axis.
For a line parallel to y−axis ,θ= π/2.
∴m = tan π/2 = undefined
The new road will therefore have 0° of inclination if it is perpendicular to D street because if they are perpendicular and D street is vertical, the new road is level and has 0° of inclination.
An horizontal line now has zero slope.
The new road has a zero slope as a result.

What is the solution of the system of equations y 4x 4 y 3x 3?.
After solving, the solution of the pair of equation is (-1, 0).
In the given question, we have to find the solution of the system of equations y = 4x + 4 and y = -3x - 3.
The given equations are:
y = 4x + 4.....................(1)
y = -3x - 3.....................(2)
Now putting the value of y from equation 1 to the equation 2
4x + 4 = -3x - 3
Subtract 4 on both side, we get
4x = -3x - 7
Add 3x on both side, we get
7x = -7
Divide by 7 on both side, we get
x = -1
Now putting the value of x in equation 1
y = 4(-1) + 4
y = -4 + 4

an isosceles triangle of sides 100cm, 60cm, and 60 cm has a base angle f, find f
Answer:
33.56°
Step-by-step explanation:
Base angles of an isosceles triangle are equal.
Base is bisected by a line from top (vertex) of the triangle straight down to form a right angle. Base, 100 cm, has 2 equal segments, 50 cm each.
Find h, height of the triangle:
h² = 60² - 50²
h = √1100 = 33.17
sin(f) = 33.17/60 = 0.553
m∠f = sin⁻¹(0.553) = 33.56°
How do you calculate equivalent form?.
To calculate equivalent form of an algebraic expression we can use the following :
1) distributing property
2) factoring.
Two mathematical expressions are said to be equivalent if they yield the same result upon solving them. To represent equivalent form an equality (=) sign is used. 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. To calculate equivalent form by using Distributive Property :
Start with an algebraic expression. Let's take an example 2x(3y + 2).Distribute the multiple 2x throughout the rest of the equation. That is multiplying 2x by 3y and by 2, we get 6xy + 4x.This is our equivalent expression. It can be represent as equality : 2x(3y + 2) = 6xy + 4x.To calculate equivalent form Using Factoring :
Identify the common factors in the expression. If possible divide the equation to find an equivalent expression.Let the expression 5xy + 4x, in this case, both numbers 4 and 5 are co-prime. As we see that there is common factor, x. Take the other common factors: x(5y + 4).This gives you an equivalent form . Again, the equality form, 5xy + 4x = x(5y + 4). Thus, the required equivalent form is determined.

How do you find the sides of a 30 60 90 triangle?.
A 30-60-90 triangle is a special type of right triangle that has angles of 30 degrees, 60 degrees, and 90 degrees. It has the following properties:
The side opposite the 30-degree angle is half the length of the hypotenuse (the side opposite the 90-degree angle).
The side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle.
To find the sides of a 30-60-90 triangle, you can use these properties.
If you know the length of the hypotenuse (the side opposite the 90-degree angle), you can find the length of the other two sides using the following formulas:
The side opposite the 30-degree angle: hypotenuse / 2
The side opposite the 60-degree angle: (√3) * (hypotenuse / 2)
If you know the length of one of the other two sides, you can use the above formulas to find the length of the hypotenuse and the other side.
For example, if you know the length of the side opposite the 30-degree angle, you can find the length of the hypotenuse by multiplying it by 2 and the length of the side opposite the 60-degree angle by multiplying it by √3
In summary:
The hypotenuse is always twice the length of the shorter leg.
The longer leg is √3 times the length of the shorter leg.
The hypotenuse is always the longest side in a 30-60-90 triangle.

An investor invested a total of $3,200 in two mutual funds. One fund earned a 6% profit while the other earned a 4% profit. If the investor's total profit was $152, how much was invested in each mutual fund?
$1200 was invested at a mutual fund of 6% profit while $2000 was invested at a mutual fund of 4% profit
What is an equation?An equation is an expression showing the relationship between numbers and variables.
Let x represented the money at 6% profit and y represent the money at 4% interest. A total of $3200 was invested, hence:
x + y = 3200 (1)
If the investor's total profit was $152, therefore:
0.06x + 0.04y = 152 (2)
From both equations:
x = 1200, y = 2000
$1200 was invested at 6% while $2000 was invested at 4%

Solving the 2 equations will give us the value of x to be -14 and that of y to be 33.
Here we have two equations
2x + y = 5 and 3x - 2y = 4
Now we will use the substitution method to solve the equations
The first equation is
2x + y = 5
or, y = 5 - 2x [1]
Let 3x - 2y = 4 be equation 2
Substituting the value obtained in equation [1] in [2] we get
3x - 2(5 - 2x) = 4
or, 3x - 10 + 4x = 4
or, x = -14 [3]
Substituting the value of x obtained in equation [3] to equation [1] we get

a. On the 13th day the company sold the same number of each player.
b. 2,451 players were sold on that day.
a. The day on which the company sold the same number of players can be calculated by equating the values of y that we have ;
y = 191x-32 and y = -x² + 200x + 20
Equating both, we have;
191x-32 = -x² + 200x + 20
⇒x² -200x + 191x-20-32 = 0
⇒x²-9x-52 = 0
⇒x²-13x + 4x -52 = 0
⇒x(x-13)+4(x-13) = 0
⇒(x-13)(x+4) = 0
⇒x = 13 or -4
as days cannot be negative, so we choose only x = 13
This means that the company sold equal numbers of players on the 13th day.
