Answer:
The supplement is 94
Step-by-step explanation:
Supplementary angles add to 180 degrees
Let x be the supplementary angle
x+86 = 180
Subtract 86 from each side
x+86-86 =180-86
x = 94
Answer:
7
Step-by-step explanation:
The diagonal is the hypotenuse of the right triangle with legs 7
Use Pythagoras' identity to solve for the diagonal d
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
d² = (7
)² + (7
)²
= 147 + 147
= 294 ( take the square root of both sides )
d =
= 7
≈ 45.37 ( to 2 dec. places )
Answer:
x intercept: (1,0)
y intercept: (0,3)
Step-by-step explanation: Substitute variables for 0 and solve
Answer:
D. (–3, –6) and (5, 10)
Step-by-step explanation:
The system has equations:
...(1)
and
...(2)
Equate both equations;

Rewrite in standard form:

We factor to obtain:

By the zero product principle;


When x=-3, y=2(-3)=-6
This yields the ordered pair (-3,-6).
When x=5, y=2(5)=10
This yields the ordered pair (5,10).
The correct choice is D.
