Answer:
The numbers are (x,y)=(-5,8) or (8,-5)
Step-by-step explanation:
Let two numbers be x and y,
We have,
x+y=3
x=3-y---(i)
Now,
xy=-40
(3-y)y=-40 [From (i)]
3y-y^2=-40
y^2-3y-40=0
Factoring,
(y + 5) (y - 8)=0
Either,
y+5=0 or, y-8=0
y=-5 y=8
When y=-5,
x=3-y
3--5
3+5
8
When y=8,
x=3-y
3-8
-5

The volume of this sphere is 972 pi cubic inches. What is its radius?
A sphere.
Recall the formula Sphere Volume = four-thirds pi r cubed.
7 inches
9 inches
108 inches
324 inches
volume of a sphere = ⁴/₃ πr³
⇒ 972π in³ = ⁴/₃ πr³
729 in³ = r³
r = 9 in
∴ the radius of a sphere of volume 972π in³ is 9 inches.Answer:
9 inches

Here’s why:
⸻⸻⸻⸻
[tex]7x - 8(-x+7)=-16+7\\\--------------\\\rightarrow7x +8x - 56 =-16 + 7x\\\\\rightarrow 15x -56 = 7x - 16\\\\\rightarrow 15x - 7x - 56 = 7x - 7x - 16\\\\\rightarrow 8x - 56 =-16\\\\\rightarrow 8x - 56 + 56 = -16 + 56\\\\\rightarrow 8x = 40\\\\\rightarrow\frac{8x=40}{8}\\\\\rightarrow \boxed{x = 5}[/tex]
