Hello!
To find cosine, use the formula cos = adjacent / hypotenuse.
According to angle B, adjacent of angle B is side A, and the hypotenuse is side c because the hypotenuse is always opposite the right angle.
Therefore, the cosine of angle B is a/c.
Answer: instead of X put 5 and instead of y put 2
5+6(2)
5+12= 17
Answer:
Option D graph
Step-by-step explanation:
x - 4 ≥ - 1
add 4 to both sides, x - 4 + 4 ≥ - 1 + 4
x ≥ 3
so x is greater than or equal to 3
- equal to means closed dot at 3
- greater than means arrow to the right of 3
Answer:
No solutions: 6 - 3 + 4x + 1 =_4x + _2_
One solution: 6 - 3 + 4x + 1 = _3_x + _2_
Infinite many solutions: 6 - 3 + 4x + 1 = _4_x + _4_
Step-by-step explanation:
No solutions means it results in no x and a false statement like 3 = 0.
One solution means it results in x = a number.
Infinite solutions means its results in no x and in a true statement like 3=3.
- So to get No solutions: 6 - 3 + 4x + 1 =_4x + _2_
This will eliminate the x and result in 4 = 2 which is false.
- One solution: 6 - 3 + 4x + 1 = _3_x + _2_
This will result in x= -2
- Infinite many solutions: 6 - 3 + 4x + 1 = _4x + 4__
This will eliminate the x and result in 4 = 4 which is true.
