Answer:

p = -4, q = -3

Step-by-step explanation:

y = -2x +4  ... (1)   perpendicular bisector of AB, slope = -2

slope of AB = 1/2

Line AB pass (8,3): (y-3) / (x-8) = 1/2

AB equation: y-3 = 1/2(x-8)      y = 1/2x - 1  ... (2)

(2)-(1): 5/2 x = 5      x = 2

y = 0       (2,0) intercept of bisector and AB, it is midpoint of A (8,3) and (p,q)

(8+p)/2 = 2

p = -4

(3+q)/2 = 0

q = -3

The values of p and q from the perpendicular bisector are;

p = -4 and q = -3

We are given coordinates of A and B as;

A(8, 3) and B(p, q)

Bisector of AB is y = -2x + 4

Thus, from y = mx + c, Slope of the bisector is -2.

Since the bisector is perpendicular to AB, then slope of AB = -(1/-2) = 1/2

Thus, slope of the line from point A to the point of the bisector on AB is;

(y - 3)/(x - 8) = 1/2

y - 3 = ¹/₂(x - 8)

y - 3 = ¹/₂x - 4

y = ¹/₂x - 1

Putting ¹/₂x - 1 for y in the bisector equation gives;

¹/₂x - 1 = -2x + 4

2x + ¹/₂x = 4 + 1

2.5x = 5

x = 5/2.5

x = 2

Thus;

y = -2(2) + 4

y = 0

Thus, the coordinate of the midpoint of AB is (2, 0)

Now, this means that;

(8 + p)/2 = 2

8 + p = 4

p = 4 - 8

p = 4

Also; (3 + q)/2 = 0

3 + q = 0

q = -3

Answer:

(3, -7)

Step-by-step explanation:

y = x² - 6x + 2

a = 1, b = -6

[tex]x = - \frac{ - 6}{2 \times 1} [/tex]

x = 3

y = x² - 6x + 2; x = 3

y = -7

= (3, -7)

Answer:

10ft by 12ft

Step-by-step explanation:

Step 1 : Find the area of the garden.

Area formula = length * width

Area = 8 * 12

Area = 96

Step 2 : Find 25% of 96.

96 divided by 4 = 24

Step 3 : Add that 25% (24) onto 96.

24 + 96 = 120

We now know that the new area of the garden is 120 [tex]feet^{2}[/tex].

The new dimensions of the garden could be 10 times 12, since that equals 120. Therefore, the answer is 10ft by 12ft.

Answer: It's possible to change a negative sign to a minus sign because for example when you have two integers 5 and -3, 5-3 is the exact same as 5+(-3). So basically, adding a negative number and a positive number is the same as subtracting the larger absolute value from the number with the lower absolute value

Answer: D

Step-by-step explanation:

2/3 divided by 2/9 = 3

a n = a 1 ⋅ r^( n − 1)

an = (2/9) * 3^(n-1)

To find the slope-intercept form (y=mx+c), we have to make 'y' the subject of the equation:

3y - 3x = 21                     [add 3x to both sides]

      3y = 3x + 21             [divide all terms by 3]

        y = x + 7

Answer:

x- intercept = -3 units

y- intercept = 6 units

Answer: y intercept=6 x intercept=-3

Step-by-step explanation:

The y-intercept is when x is 0 so we plug in the value of x with 0 and solve for y.

Similarly, the x-intercept is when y is 0 so we plug in the value of y with 0 and solver for x.

Answer:

p = - 4

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to - 4

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, p ) and (x₂, y₂ ) = (- 4, 0 )

m = [tex]\frac{0-p}{-4-(-3)}[/tex] = [tex]\frac{-p}{-4+3}[/tex] = [tex]\frac{-p}{-1}[/tex] = p = - 4
