answer is (-7,2)
y = -x -5
y= x+9
Both equations have y on the left hand side
So we equate both equations
We replace -x-5 for y in the second equation
-x -5 = x+9
Subtract x on both sides
-2x -5 = 9
Now add 5 on both sides
-2x = 14
Divide by -2 from both sides
x = -7
Now plug in -7 for x in the first equation
y = -x -5
y = -(-7) -5= 7-5 = 2
So answer is (-7,2)
Writing this word problem symbolically: 6x + 4 = x = 11.
Combining like terms, 5x = 7, and so x = 7/5 (answer)
Answer:
<u>6</u>
<u>4</u>
<u>12</u>
<u>72</u>
Step-by-step explanation:
Base is 6 in
Height is 4 in
To get the area of a triangle is 1/2 Base × Height
Being 1/2(6)(4) = 12
To get the area of a rectangle is Length × Width being 9 × 8 = 72
