Is Y =- 2x 5 in standard form?.
The equation y = -2x + 5 is already in the standard slope intercept form.
The slope-intercept form is a way of expressing the equation of a straight line in algebraic terms. The equation of a line in slope-intercept form is typically written as:
y = mx + b
Where m represents the slope of the line and b represents the y-intercept, which is the point at which the line crosses the y-axis. The slope-intercept form is useful because it allows you to quickly identify the slope and y-intercept of a line, given its equation. The slope represents the rate of change of y with respect to x, and the y-intercept represents the initial value of y when x is equal to 0. By using slope-intercept form we can easily graph the line and also can find the equation of the line from the graph.

After a certain number of people entered an empty room, 2/3 of the people who’d entered the room leave. After 2 more people leave, 1/4 of the original number of people who entered the room remain. What was the original number of people who entered the empty room?
Answer:
24
Step-by-step explanation:
Let x be the original number of people who entered the room
Since 2/3 of the people leave, 1/3 of the people remain = (1/3)x
If 2 more people leave, number of people remaining in the room = (1/3)x - 2
We know this to be 1/4 of the original number = (1/4)x
[tex]\rm{So\;\dfrac{1}{3}x - 2 = \dfrac{1}{4}x\\\\[/tex]
Multiply throughout by 12 to get rid of the denominator
[tex]\rm{So\;12 \left(\dfrac{1}{3}x - 2\right) = 12\left(\dfrac{1}{4}x\right)\\\\[/tex]
[tex]4x - 24 = 3x\\\\\implies x = 24\\\\[/tex]

The histogram shows the ages of all the workers in a London office. Given that 27 people are in the 40-55 age range, work out the total number of people in the office.
Using the same method, determine the histogram's total area: divide it into rectangles and use the calculation for a rectangle's area to arrive at a total area of 100.The answer 40.
Determine the histogram's total area:
The area below the 40 to 55 line in the histogram must first be located.By using the area of a rectangle, one can determine the area: side side.
This will reveal a 60-square-foot space.
Then, using the same method, determine the histogram's total area: divide it into rectangles and use the calculation for a rectangle's area to arrive at a total area of 100.
You must now apply the rule of three:
The number of people between the ages of 40 and 55 is 25, and that age range corresponds to 60, as indicated by the question's sentence, so:
60 ———- 24
100 ———- x

What is the formula of area of acute angle triangle?.
The formula for area of an acute angle triangle is (½) × b × h
a triangular shape with three acute angles. It indicates that none of the angles are precisely 90 degrees. Any triangle with all interior angles being acute angles is said to have an acute angle triangle. The line traced from the base of the triangle to the opposite vertex of an acute triangle is always perpendicular. The formula for the area of an acute angle triangle is (½) × b × h
Based on the side dimensions and angles of the triangles, one can classify acute triangles into distinct categories. One of them is an equilateral triangle with equal-length sides and interior angles, every sixty degrees in length. A triangle that is equilateral is always sharp. An acute isosceles triangle has two equal sides, and its opposing angles are also of equal length. A scalene acute triangle has uneven sides and internal angles on each of its three dimensions. The sum of all angles is less than 90 degrees.

Find the equation of the straight the line which passes through the point (3, 2) and cuts off equal intercepts on the axes.
Answer: The equation of a line can be written in the slope-intercept form y = mx + b, where m is the slope of the line and b is the y-intercept.
To find the equation of a line that passes through the point (3, 2) and cuts off equal intercepts on the x and y axes, we can use the following steps:
First, we need to find the slope of the line using the point (3, 2) and the fact that the line cuts off equal intercepts on the x and y axes. Since the line cuts off equal intercepts on the x and y axes, it means that it is a line of symmetry, which means that the slope of the line is zero.
Now we can use the point-slope form of a linear equation which is y-y1 = m(x-x1) and substitute the point (3,2) and the slope (0)
The equation of the line will be y = b where b is the y-intercept.
So the equation of the line which passes through the point (3, 2) and cuts off equal intercepts on the axes is y = 2
The line is a horizontal line passing through the point (3,2) and it cuts the x-axis at y = 2.

The coordinates where the wood strips cross are (17.11,44). The solution is obtained using the concept of slope of line.
What is slope of line?
The change in y coordinate relative to the change in x coordinate is referred to as a line's slope in mathematics.
The symbols delta y and delta x stand for the net change in the y-coordinate and the net change in the x-coordinate, respectively.
We are given that Hana attaches thin strips of wood from each vertex perpendicular to the opposite edge.
Therefore, the point of concurrency will be in orthocenter.
We are given a triangle with coordinates X(0,0), Y(0,58), Z(36,44)
Now, we will find the slope
Slope(m) = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Slope of XY = (58-0)/0-0 = 0
Slope of YZ = (44-58)/(36-0) = -7/18
We know that slope of line perpendicular to XY is 0
Using point slope form, equation of the altitude perpendicular to XY is
⇒[tex]y-y_{1} = m(x-x_{1} )[/tex]
⇒y-44 = 0(x-36)
⇒y=44
Slope of line perpendicular to YZ is 18/7
Using point slope form, equation of the altitude perpendicular to YZ is
⇒y-0 = 18(x-0)/7
⇒y = 18x/7
Substitute the value of y in the above equation, we get
⇒44 = 18x/7
⇒x = 17.11
Hence, the coordinates where the wood strips cross are (17.11,44).
