Answer:
Step 1: 14x − 21 = 1; Step 2: 14x = 22
Explanation:
7(2x−3)=1
Step 1: Simplify both sides of the equation
7(2x−3)=1
(7)(2x)+(7)(−3)=1(Distribute)
14x+−21=1
14x−21=1
Step 2: Add 21 to both sides
14x−21+21=1+21
14x=22
Step 3: Divide both sides by 14
14x / 14 = 22 / 14
x = 22 / 14: x = 11/7
Hello!
Lets go through each choice, and determine if it is correct.
So, the symbol ≤, means less than or equal to. So our answer must be less than -75 or -75 on the dot.
A: y = 75
Okay, so we can tell this one is wrong off the bat. 75 is much more than -75. (Make sure you notice the symbol!) So it cannot be equal to said answer. A is wrong.
B: y =-74
Another trick question! When you are in the negatives, less is more! So -74 is actually greater than -75. This is also incorrect!
C: y > -75
This one is straight forward. Our equation up top strictly says <em>less than or equal too</em>, while C says greater than. Incorrect!
D: y = -75
The last answer! We see that the symbol in our equation up top says less than or equal too, and y = -75 is equal. This is the correct answer.
Our correct answer is D: y = -75

Step-by-step explanation:
Answer:
-√7/4
Step-by-step explanation:
Mathematically;
Sine is the ratio of opposite to hypotenuse
So here, hypotenuse is 4
The opposite is 3
To get the adjacent, we use the Pythagoras’ theorem which states that the square of the hypotenuse is equal the sum of the squares of the two other sides
Let the adjacent be x
4^2 = 3^2 + x^2
x^2 = 16-9
x^2 = 7
x = √7
The cosine is the ratio of the adjacent to the hypotenuse
Since we want to consider quadrant II
Cosine is negative here;
So the answer for Cos will be;
Cos theta = -√7/4
20,000/10=2,000 :)
Good luck
