Please help me it due today at 11:00pm please will mark the brainiest please
gregori [183]

Answer:

d = 2.75 or 11/4

Step-by-step explanation:

15 = 5 + 4(2d - 3)

15 = 5 + 8d - 12

15 = 8d - 7

<u>+7        + 7</u>

22 = 8d

22/8 = d

2.75 = d

Check:

15 = 5 + 4(2(2.75) - 3)

6+8x-9=11x+14-3x, can this equation be always, sometimes, or never true.
goblinko [34]
To answer the question above, simplify both sides of the equation. This gives,
                         8x - 3 = 8x + 14
Next, cancel the term 8x because it appears on both sides of the equation giving,
                             -3 = 14
That is NOT true. Therefore, the answer is the equation is NEVER TRUE.

1. The equation of the locus of a point which is always equidistant from the points (a + b, a - b) and (a - b, a + b) is a) x -
valina [46]

Answer:

c). y + x = 0

Step-by-step explanation:

The locus is a line perpendicular to the line connecting the 2 points and passing through the centre of the line.

The mid-point of the line connecting the given points is:

(a + b + a - b)/2 , (a - b + a + b) / 2

= (a, a)

It's slope = (a + b)- (a - b) / (a - b)- (a + b)

= 2b/ -2b

= -1

So the slope of the line we want is -1/(-1) = 1.

Using the point-slope form of a line:

y - y1 = m(x - x1)

y - a = 1(x - a)

y - a = x - a

x + y = 0

Combine and simplify the following radical expression.
guajiro [1.7K]

Answer:

<h2>24 \sqrt{5}</h2>

Step-by-step explanation:

2 \sqrt{20}  + 8 \sqrt{45}  -  \sqrt{80}

= 2 \sqrt{2 \times 2 \times 5}   + 8 \sqrt{3 \times 3 \times 5}  -  \sqrt{2 \times 2 \times 2 \times 2 \times 5}

= 2(2 \sqrt{5} ) + 8(3 \sqrt{5} ) - (4 \sqrt{5} )

= 4 \sqrt{5}  + 24 \sqrt{5}  - 4 \sqrt{5}

= 24 \sqrt{5} (ans)
