Given RT below, if S lies on RT such that the
ratio of RS to ST is 3:1, find the coordinates
of S.
Answers
Answer:
(-2, -3)
Step-by-step explanation:
If a segment having extreme ends as [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is divided by a point (x, y) in the ratio of m:n,
x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]
y = [tex]\frac{my_2+ny_1}{m+n}[/tex]
Since, a line RT has extreme ends as R(-5, 3) and T(-1, -5) then a point S(x, y) which divides RT in the ratio of 3 : 1 will be,
x = [tex]\frac{3(-1)+1(-5)}{3+1}[/tex]
= [tex]\frac{-8}{4}[/tex]
= -2
y = [tex]\frac{3(-5)+1(3)}{3+1}[/tex]
= [tex]-\frac{12}{4}[/tex]
= -3
Therefore, coordinates of the point S will be (-2, -3).
A square of an unknown side length x inches has one side length increased by 4 inches and the other increased
by 7 inches
(a) If the original square is shown below with side lengths marked as x, label the second diagram to represent the new rectangle constructed by increasing the sides as described above.
Answers
Answer:
Length of new rectangle = (x + 7) inches
Width of new rectangle = (x + 4) inches
Step-by-step explanation:
A rectangle is a quadrilateral that has opposite sides to be parallel and equal. While a square has all its sides to be equal.
Given that: the square has unknown side length x inches.
Increasing one of its length by 4 inches = (x + 4) inches
Increasing the other by 7 inches = (x + 7) inches.
The new lengths results to a rectangle with length (x + 7) inches, and a width of (x + 4) inches.
the label diagram to represent the new rectangle is shown in the diagram attached to this answer.
If x = 3y and y = 9, what is the value of 3x – 2?
Answers
Answer: 79
Step-by-step explanation: Lets first deal with the X. The equation would be 3 X 3 X 9. This answer is 81. Next we have 81 - 2. Therefore, our answer is 79. Do multiplacation first as M is before S in peMdaS.
Answer:
79
Step-by-step explanation:
x = 3y and y = 9
This means x = 3*9 = 27

How can I subtract 3x from both sides? Explanation and answer
Answers
Its not must that 3x have to be the one to be subtracted. You could take 8x as well.
But always subtract from the smaller one (in this case 3x) because its easier.
If you are subtracting 3x-3x and 8x-3x, the equation would be like
4 = 5x - 16
5x = 4+16
5x = 20
x = 4

Answers
Answer:
Step-by-step explanation:
9x-4= 3x-28
We simplify the equation to the form, which is simple to understand
9x-4=3x-28
We move all terms containing x to the left and all other terms to the right.
+9x-3x=-28+4
We simplify left and right side of the equation.
+6x=-24
We divide both sides of the equation by 6 to get x.
x=-4
