The point P has coordinates (-2,6).The point M has coordinates (5,6)
nekit [7.7K]
Find the gradient/slope
6-6/5-(-2) deltaY/deltaX
=0 shows its a straight line
Delta X = 7
Distance between P & M = 7 units
If M is the midpoint then Q is 7*2 units
Away from P (14 units away)
-2 + 14 units = 12 x-coordinate
Hence the coordinates of Q
= (12,6)

FINAL ANSWER:
Coordinates of Q (12,6)

The factorization below is missing two positive integers a and b. 6x^(3)+18x^(2)-240x=6x(x-a)(x+b) Factor the polynomial and the
Dvinal [7]

Answer:

a = 5

Step-by-step explanation:

Hello, please consider the following.

6x^3+18x^2-240x=6x(x^2+3x-40)\\\\\text{** The sum of the zeroes is -3=-8+5 and the product is -40=-8*5. **}\\\\\text{** So, we can factorise. **}\\\\6x^3+18x^2-240x=6x(x^2+3x-40)=6x(x^2+8x-5x-40)\\\\=6x(x(x+8)-5(x+8))\\\\\large \boxed{=6x(x+8)(x-5)}

So, a = 5.

Thank you.

The vertices of a triangle are A(4, 1), B(9, 1), C(2, 5). What is the area of this triangle.
kiruha [24]

Hey there!

\large\boxed{10u^2}

Formula for the area of a triangle is (1/2)bh.

Base of this triangle is 5, height is 4.

Image attached.

Plug values into the formula:

A = (1/2)(5)(4)

Simplify.

A = (1/2)(20)

A = 10

Area of the triangle is 10 units².

Hope this helps!

Answer:

10 miles per minute

Step-by-step explanation:

distance = speed x time

but we are working out the speed, so it is speed = distance/ time
