Answer:
[tex]y=\frac{-2}{3} x-15[/tex]
Step-by-step explanation:
First draw a line. I will put it in an attachment so you can see the line.
Now choose to points on the line to use the slope formula.
(0,15) and (3,13).
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Plug in the information needed using the two points chosen.
[tex]\frac{13-15}{3-0}=\frac{-2}{3}[/tex]
The slope is [tex]\frac{-2}{3}[/tex].
Now use point-slope formula.
Point-slope formula: y-y1=m(x-x1)
y-15=[tex]\frac{-2}{3}[/tex](x-0)
y-15=[tex]\frac{-2}{3}[/tex]x-0
Subtract 15 from both sides.
y=[tex]\frac{-2}{3}[/tex]x-15
Hope this helps!

A pole that is 2.8 tall casts a shadow that is 1.79 long. At the same time, a nearby building casts a shadow that is 42.25 long. How tall is the building? Round your answer to the nearest meter.
Answer:
The building is around 47 meters tall
Step-by-step explanation:
Pole:
tall/long
2.8/1.79
Building:
tall/long
x/42.25
Solve for x:
2.8/1.79 = x/42.25
1.79x = 84.5

The ratio that compares the men to the women who work at the warehouse is 4 : 1.
What is a ratio?A ratio is a value that shows the proportional relationship between two quantities.
A ratio indicates how many times one number is contained in another.
For example, in the above task, there is 4x the number of men when compared with the number of women who work at the warehouse.
Data and Calculations:Men working at the warehouse = 1,200
Women working at the warehouse = 300
Ratio of men to women = 4 : 1 (1,200 : 300)
Thus, the ratio that compares the men to the women who work at the warehouse is 4 : 1.

Step-by-step explanation:
The figure shows a circle circumscribed around a triangle.
Triangle U T V is inscribed within a circle. A point is at the center of the triangle. Lines are drawn from the points of the triangle to the point in the middle. Lines are drawn from the point in the middle to the sides of the triangle to form right angles.
What is constructed first when creating the circle?
perpendicular segments to the vertices of the triangle
perpendicular bisectors of the sides of the triangle
angle bisectors of each angle of the triangle
the incenter of the triangle
Option B is right perpendicular bisectors of the sides of the triangle
What circumcircle?If we draw a circle through all the vertices of a triangle then the circle obtained is the circumcircle of the given triangle. We have in a triangle there are some properties inherent.
One is the perpendicular bisectors of all sides are concurrent. These three concur at a point called the circumcentre of the triangle.
When we draw a perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistant from A and B.
When we take the point of intersection of the perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C
In short, this is equidistant from all 3 vertices and hence is the centre of the circumcircle of triangle ABC
Therefore Option B is right perpendicular bisectors of the sides of the triangle.

Hello !
Answer:
Step-by-step explanation:
Pythagorean Theorem : a² + b² = c² ⇔ b² = c² - a²
Here, we have a = 4 and c = 6 so :
b² = 6² - 4²
⇔ b² = 36 - 16
⇔b² = 20
⇔ b = √20 (and not b= -√20 because b ≥ 0)
Answer:
b = [tex]\sqrt{20}[/tex]
Step-by-step explanation:
Using the Pythagorean Theorem:
6² = 4² + b²
⇒ b² = 6² - 4²
⇒ b = [tex]\sqrt{6^2 - 4^2}[/tex]
⇒ b = [tex]\sqrt{36 - 16}[/tex]
⇒ b = [tex]\sqrt{20}[/tex]
Given the midpoint B (-41, 23), create 2 different set of end points that don’t have the same x or y value of the midpoint. Verify your points by solving for the midpoint and identify them as points G and H. Show your work to prove your answer
can someone pleas help
Using the mid-point concept, the set of points that has midpoint B(-41,23) is: G(10,10) and H(-92,36).
What is the mid-point concept?The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.
In this problem, we have that:
The mid-point is B(-41,23).The other points are G(10,10) and H(x,y).Hence the coordinates of H are found as follows:
[tex]-41 = \frac{10 + x}{2}[/tex]
10 + x = -82.
x = -92.
[tex]23 = \frac{10 + y}{2}[/tex]
10 + y = 46.
y = 46.

A coordinate plane with a line drawn passing through the points (0, 3) and (1,1). which equation represents the graphed function? y = –2x 3 y = 2x 3 y = x 3 y = –x 3
Answer:
y = - 2x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3 ) and (x₂, y₂ ) = (1, 1 )
m = [tex]\frac{1-3}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2
the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - 2x + 3 ← equation of line

The length of a rectangle is increased by 25% , but the width of the rectangle is decreased by 25%. By what percent was the rectangle's area decreased
The rectangle's area decreased by 19%.
Length = L
Breadth = B
Original area = L x B
New area = A = L x (1 + 25%) x B x (1 - 25%)
A = L x B x 0.25 x 0.75 = L x B x 1.05
Therefore the area of the rectangle has decreased by 19%.
To find the location of a rectangle, multiply its width by means of its height. If we understand the sides of the rectangle which are different lengths, then we have each the height and the width.
The perimeter P of a rectangle is given through the system, P=2l+2w, wherein l is the period and w is the width of the rectangle. The area A of a rectangle is given by means of the method, A=lw, in which l is the duration and w is the width.

The inequality is:
3x - 11 > 7x + 9
After simplification:
3x - 7x > 9 + 11
-4x > 20
-x > 5
Multiplying by a negative sign on both sides:
x < -5
The number line can be defined as the representation of the numbers on a straight line that goes infinitely on both sides.

For the first picture determine the equation of the parabola shown in the diagram in vertex form and for the second picture determine the equation of the parabola shown in the diagram in factored form.
Answer:
see explanation
Step-by-step explanation:
the equation of parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier.
here (h, k ) = (3, 1 ) , then
y = a(x - 3)² + 1
to find a substitute any other point on the graph into the equation.
using (0, 7 )
7 = a(0 - 3)² + 1 ( subtract 1 from both sides )
6 = a(- 3)² = 9a ( divide both sides by 9 )
[tex]\frac{6}{9}[/tex] = [tex]\frac{2}{3}[/tex] = a
y = [tex]\frac{2}{3}[/tex] (x - 3)² + 1 ← in vertex form
------------------------------------------------------
the equation of a parabola in factored form is
y = a(x - a)(x - b)
where a, b are the zeros and a is a multiplier
here zeros are - 1 and 3 , the factors are
(x - (- 1) ) and (x - 3), that is (x + 1) and (x - 3)
y = a(x + 1)(x - 3)
to find a substitute any other point that lies on the graph into the equation.
using (0, - 3 )
- 3 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )
1 = a
y = (x + 1)(x - 3) ← in factored form
