Answer:

x = 7 units

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

5 cm 3 cm

------------------ = ------------------------

(40 + 5) cm (3 + 2x + 10) cm

This simplifies to:

5 3

-------- = -----------

45 2x + 13

Solve for x. Cross-multiplying, we get:

10x + 65 = 135, or x = 7

So x = 7 units.

Given BE= 2x+6 and ED= 5x-12 in a parallelogram ABCD, find BD

Brrunno [24]

1.BE = 2x + 6
ED = 5x - 12
2. To get the entire side of BD, we must add both half's which equals to the entire length.
3. 2x + 6 + 5x - 12
4.Add like terms.
2x + 5x = 7x
-12 + 6 = -6
5. So, we have 7x - 6

=7x - 6

Question 2

fomenos

Answer:

D. (-2,-5), (0, -7), (1, -4)

Step-by-step explanation:

From Function Theory we must remember that range of a function is the set of images related to elements of the domain. In this case, we must find the image of each of the three elements that forms the domain of $f(x, y) = (y+2, -x-4)$ , which are: $A(x,y) = (1, -4)$ , $B(x,y) = (3,-2)$ and $C(x,y) = (0,-1)$ .
