1st , 3rd and last option is correct
If we let the score of team tackle as x, then the score of team sack x - 7. Their combined scores totaled 83, in equation form, that is:
x + x - 7 = 83
Solving for x
2x = 83 + 7
2x = 90
x = 45
x - 7 = 38
The two scores are 45 and 38.<span />
Answer:
Step-by-step explanation:
To find an equation of the sphere with center (4, −12, 8) and radius 10

intersection with xy-plane
Put z=0


(A circle with centre at (4,-12) and radius 6)
intersection with xz-plane
Put y =0


Sum of squares cannot be positive, so DNE
intersection with yz-plane
Put x=0


A circle in YZ plane with centre at y =-12 and z =8 and radius square root of 84
