X= -8/5y+16
y= -5/8x+10
you didnt say if the equation was "5x+8y=80" not sure if your adding or subtracting or adding but if your adding then this is correct :)
6.4n^2 is correct. math papa helps
Hey there!
<u>Solve </u><u>the </u><u>equation </u><u>:</u>
x = 2 ✅
7x + 8 = -5x + 32
<em>></em><em>></em><em> </em><em>Su</em><em>bstract </em><em>8</em><em> </em><em>from </em><em>e</em><em>ach </em><em>side </em><em>:</em>
7x + 8 - 8 = -5x + 32 - 8
7x = -5x + 24
<em>></em><em>></em><em> </em><em>Add </em><em>5</em><em>x</em><em> </em><em>to </em><em>both </em><em>sides </em><em>:</em>
7x + 5x = -5x + 24 + 5x
12x = 24
<em>></em><em>></em><em> </em><em>Divide </em><em>both </em><em>sides </em><em>by </em><em>1</em><em>2</em><em> </em><em>:</em>
12x / 12 = 24 / 12
x = 2
Therefore, your answer is x = 2

Answer:
1. The difference of two odd numbers is a multiple of <u>2</u>
2. | -56 | = 56
Step-by-step explanation:
1. Since the difference between two odd numbers is always even, this means the difference of two odd numbers is a multiple by 2. This is because all even numbers are divisible by 2.
2. The absolute value of | -56 | would be 56

Answer:
- a = 0.5
- b = π/4.5
- c = 7π/9
- d = -4.5
Step-by-step explanation:
The value of d is the average of the maximum and the minimum.
d = (-4 +-5)/2 = -9/2 = -4.5
The value of 'a' is the difference between the maximum and d.
a = -4 -(-4.5) = 0.5
The value of b is 2π divided by the period. Here, the half-period is 3.5 -(-1) = 4.5, so ...
b = 2π/9 = π/4.5
The value of c is the value that makes the cosine argument zero at x=3.5.
(π/4.5)(3.5) +c = 0
c = -7π/9
