Answer:
F
Step-by-step explanation:
Andrew, Blake, Jamal, Ernesto
The first step to solving this is to solve the equation for x
x = - 21/5 - y
4x + 4y = -14
now,, substitute the given value of x into the equation "4x + 4y = -14"
4( - 21/5 - y) + 4y = -14
next,, solve the equation for y
y∈∅
since this system has no solution for y, your answer is (x,y)∈∅
let me know if you have any further questions

4x-3y=-9
The first step is to isolate your y value.
Subtract 4x from both sides to get
-3y=-4x-9
Then, divide your whole equation by -3. This gives you y=4/3+3
To graph, plot (0, 3), or three on your y-axis to get your y-intercept.
For your slope, use the rise/run (go up 4, across 3)
You should have a positive slope.
Answer:
C
Step-by-step explanation:
Te unoccupied volume (V) of the cube is calculated as
V = volume of cube - volume of sphere
= 7³ -
πr³ ( r is the radius and r = 7 ÷ 2 = 3.5 )
= 343 -
π × 3,5³
= 343 -
π × 42.875
= 343 - 179.59438
= 163.4....
≈ 160 cm³ ( to the nearest 10 cm³ )
