If ABCD is a rectangle, BD = 2x + 5 and AC = 7x - 40. Find the value of BE.

Answer:

AC = 23

BD = 23

Step-by-step explanation:

ABCD is a rectangle,

AC and BD are its diagonals.

Diagonals of a rectangle are congruent.

Therefore,

AC = BD

7x - 40 = 2x + 5

7x - 2x = 5 + 40

5x = 45

x = 45/5

x = 9

BD = 2x + 5 = 2*9 + 5 = 18 + 5 = 23

AC = 7x - 40 = 7*9 - 40 = 63 - 40 = 23

Find the value of c such that y= x + c is a tangent to the parabola y = x squared - x - 12
Bond [772]

Answer:

c = –13

Step-by-step explanation:

by property of tangent line, equation

x² – x – 12 = x + c

x² – 2x – 12 – c = 0

has only one solution, which mean

– 12 – c = 1

c = –13

6.<br> What is the midpoint of the line segment whose<br> endpoints (7,-4) and (-3, -2)?<br> are
quester [9]

Answer: (2, -3)

Step-by-step explanation:

To find the the answer, you will need to use the midpoint formula, which is as following:

(x₁+x₂/2, y₁+y₂/2)

Since we have two coordinates, let's substitute them into the equation.

(7 + (-3 )/ 2, (-4) + (-2)/2)

We should first add 7 and -3 together, as well as -4 and -2.

(4/2, -6/2)

We then divide 4 and -6 by 2. This would give us our midpoint coordinate.

(2, -3)

Subtract 5y-8 from 2y+8
Eva8 [605]

Subtract 5y - 8 from 2y + 8

To subtract two numbers, we can do it like this:

10 - 4 = 10 + (-4)

That is, add the first number with the second number with its sign changed. For simple numbers, it does not make much difference, but for algebraic expressions, it can help a lot.

To subtract both binomials, we write the first plus the second with changed signs:

2y + 8

-5y + 8

---------------

-3y + 16

The result of the subtraction is -3y+16
