None of these ordered pairs work. Each is false for at least one of the 2 equations.
(1, 0) is false for equation 1.
y > -3x + 3
0 > -3(1) + 3
0 > -3 + 3
0 > 0 (FALSE)
(-1, 1) is false for equation 1.
y > -3x + 3
1 > -3(-1) + 3
1 > 3 + 3
1 > 6 (FALSE)
(2, 2) is false for equation 2.
y > 2x - 2
2 > 2(2) - 2
2 > 4 - 2
2 > 2 (FALSE)
And (0, 3) is false for equation 1.
y > -3x + 3
3 > -3(0) + 3
3 > 3 (FALSE)
Answer: A=20
Step-by-step explanation:
3×A=30+30............eqn 1
3A=60
A=60/3
A=20
Substitute A=20 into equation 1
3x20= 30+30
the answer to your question is 13 mm
I think the answer is B. Or A.
Answer:
The height of tower
.
Step-by-step explanation:
Diagram of the given scenario is shown below.
Given that,
Distance between John and tower is
.
Angle of elevation to the top of the tower is
°.
Height of John is
.
To Find: Height of the tower
.
So,
In triangle ΔDCE,
(∠



Now,
To calculate the height of tower we have


≈ 
Therefore,
The height of tower
.
