2. Find the equation of the perpendicular bisector of line PQ where the co-ordinates of P and Q are P (-2, 8) and Q (4,7)
Answers
Answer:
2y - 12x = 3
Step-by-step explanation:
gradient of line PQ= (7-8)/ 4+2
-1/6
gradient of perpendicular bisector of line PQ=
-1 ÷ -1/6
-1× -6
6
coordinates of the midpoint of line PQ
(-2+4)/2, (8+7)/2
(1, 15/2)
the perpendicular bisector passes through the midpoint of line PQ
Equation of the perpendicular bisector
y - 15/2 = 6(x - 1)
multiply through by 2
2y - 15 = 12(x - 1)
2y - 15 = 12x - 12
2y - 12x = 3

Answers
Answer:
expanded for everything
Step-by-step explanation:
Expanded Form of 531.029:
531.029 = (5 * 102) + (3 * 101) + (1 * 100) + (2 * 1/102) + (9 * 1/103)
531.029 = (5 * 100) + (3 * 10) + (1 * 1) + (2 * 1/100) + (9 * 1/1,000)
531.029 = 500 + 30 + 1 + 2/100 + 9/1,000
531.029 = 500 + 30 + 1 + 0.02 + 0.009

Triangle DEF is dilated with respect to the origin by a scale factor of to produce ΔD'E'F'. What is the length of side D'E'?
A.
B.
C.
D.
Answers
The resulting coordinate will be D'(2, 6), E'(4, -6), and F'(0, 10),
Let the coordinate of the triangle DF be given as D(1, 3), E(2, -3) and F(0, 5).
For instance, if the coordinate point (x, y) is dilated by a factor of k, the resulting coordinate will be (kx, ky)Note that each of the coordinates is multiplied by the scale factor.
For the coordinates D(1, 3), E(2, -3), and F(0, 5), assuming the coordinate point is dilated by a factor of 2, the resulting coordinate will be D'(2, 6), E'(4, -6), and F'(0, 10),

During a chess match there are 15 pieces left on the board. the ratio of the white pieces to black pieces is 3 : 2 how many white pieces are on the white board?
Answers
==========================================================
Explanation:
The ratio 3:2 scales up to 3x:2x for some positive whole number x.
We have 3x white pieces, 2x black pieces, and 3x+2x = 5x pieces total. Set this equal to the 15 mentioned and solve for x.
5x = 15
5x/5 = 15/5
x = 3
Therefore, there are 3x = 3*3 = 9 white pieces and 2x = 2*3 = 6 black pieces, which gives 9+6 = 15 total. The ratio 9:6 reduces to 3:2 after dividing both parts by the GCF 3.
Determine the equation of a circle with center at (8, 10) and radius 6.
1) (X + 8)2 + (y - 10)2 = 36
2) (x + 8)2 + (y + 10)2 = 36
3) (x-8)2 + (y - 10)2 = 36
4)(x - 8)2 + (y - 10)2 = 6
Answers
Answer:
Step-by-step explanation:
general equation for a circle at the origin is
x² + y² = r²
if the circle center is (x₀, y₀), the formula is
(x - x₀)² + (y - y₀)² = r²
(x - 8)² + (y - 10)² = 36
3=2x

[tex] \huge \bf \: Question : [/tex]
[tex]3 = 2x[/tex]
This is an equation. We need to find the value of X and verify it.
[tex] \huge \bf \: Solution : [/tex]
Let's find out the value of X :-
[tex] \sf \implies \: 3 = 2x[/tex]
Firstly, over turn the equation :-
[tex]\sf \implies2x = 3[/tex]
Then, Divide both sides of this equation by 2 :-
[tex]\sf \implies \: \dfrac{2x}{2} = \dfrac{3}{2} [/tex]
Cancel 2/2 on this equation and Leave x :-
3/2 can't be cancelled.
[tex]\sf \implies \: \dfrac{ \cancel2x}{ \cancel2} = \dfrac{3}{2} [/tex]
[tex]\sf \implies \: x = \dfrac{3}{2} [/tex]
Hence the value of x is 3/2.
________________________________
[tex] \bf \huge \: Verification : [/tex]
Put the value of x on this equation :-
[tex]\sf \implies \: 3 = 2x[/tex]
On Putting 3/2 instead of x :-
As we know that x is multiplied with 2 so,
[tex]\sf \implies \: 3 = 2 \times \dfrac{3}{2} [/tex]
Simplify this equation(Cancel 2 and 2) :-
[tex]\sf \implies \: 3 = \cancel2 \times \dfrac{3}{ \cancel2} [/tex]
[tex]\sf \implies \: 3 = 3[/tex]
[tex]\sf \implies \bf \: L HS = RHS[/tex]
[tex] \boxed {\bf\huge Hence, verified.}[/tex]

When the denominators have no common factor, the least common denominator is their product, as here.
Answer:
For this question, you can make the denominators the same to get the answer.
LCM of 7 and 9 = 63
[tex]\frac{6}{7} + \frac{4}{9} = \frac{54}{63} + \frac{28}{63} \\[/tex]

what is the y intercept of the graph
what is the slope
Answers
Answer:
y-intercept = 1
slope = 4
Step-by-step explanation:
The y-intercept is where the line intersects with the y.
And the slope is rise over run, so it rises 4 and walks over 1, therefore the slope is [tex]\frac{4}{1}[/tex] which simplifies to 4.
Hope this helped! :)
Answer:
y intercept (0,1)
slope 4
Step-by-step explanation:
The y intercept is where the graph crosses the y axis
The graph crosses at y =1
(0,1)
We can find the slope by taking rise over run
The graph rises 4 units ( goes up 4 units)
Then goes to the right 1 units
The slope is 4/1 = 4
