What is the solution when <br> 9x+6y=-3<br><br> x+8y=29

Leya [2.2K]

We have
$9x + 6y = - 3 - - - (1)$
and

$x + 8y = 29$
$\rightarrow \: x = 29 - 8y - - - (2)$

Using elimination will be faster, so plug in equation (2) in equation (1)

$9(29 - 8y) + 6y = - 3$

Expand brackets, we obtain,

$261-72y+6y=-3$
Simplifying gives,

$-66y=-264$

$y = \frac{ - 264}{ - 66} = 4$
$x = 29 - 8(4) = - 3$

Can you help me with any of these please (not lazy don't understand )

Anarel [89]

I believe the first one is h becuase there is a y on the left side.
for the second one just find the slope for the points and see which one doesn't fit in the groups (I would use tables)
and for the last one try writing equations for them.

but idk tho that's just what I would do.

Use the perimeter to find the length of segment AD. This is the distance from A to D. Explain how you found your answer. Please

jekas [21]

Answer:

AD = 5 units

Step-by-step explanation:

Given:

Perimeter = 18 units

BC = 4 units

CD = 3 units

Required:

Length of segment AD

Solution:

Perimeter = AB + BC + CD + AD

We can easily find AB,

AB = 6 units (distance from A to B)

Plug in the values

18 = 6 + 4 + 3 + AD

18 = 13 + AD

Subtract 13 from each side

18 - 13 = 13 + AD - 13

5 = AD

AD = 5 units
