If dh = 4x – 17 and fh = x 13, find the value of x for which defg must be a parallelogram. 10 8 6 7

1 answer:

7 0

If DEFG is a parallelogram, then DF is a diagonal of a parallelogram.
DH = FH
4 x - 17 = x + 13
4 x - x - 17 = x - x + 13
3 x - 17 = 13
3 x - 17 + 17 = 13 + 17
3 x = 30
x = 30 : 3
x = 10
Answer:
A ) x = 10

Write the equation for the following table: X. Y. 0 3 1 7 2 11 3 15

Vanyuwa [196]

Answer:

$y = 4x + 3$

Step-by-step explanation:

The equation of the table of values given can be written as $y = 4x + 3$ .

When x = 0,

$y = 4(0) + 3$

$y = 0 + 3 = 3$ this corresponds with what we have in the table above.

Let's try another.

When x = 2,

$y = 4(2) + 3$

$y = 8 + 3$

$y = 11$

This also corresponds with what we have in the table.

Therefore, the equation of the table given is $y = 4x + 3$ .

Help please don’t understand

SIZIF [17.4K]

Okay all the triangles equal to 180 , so you have to add the numbers that it gives you , then subtract by 180

. for example: 33+75?= 180
33+75= 108
180-108 =72
therefore your answer is 72 (for my example)
