Which function will start at the y-axis at (0, 7)?y = 7x
y = x + 7
y = x - 7
y = x + 5
Answers
And the answer is B, y = x + 7, because at x=0, we have y = 0 + 7 = 7, which matches the given point (0,7)
intercept is c

What is Unitary Method?
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Answer
x ≥ 68
Explanation
let that number be x.
(3/4) of x = (3/4) × x
= 3x/4
Decrease 3x/4 by 9,
3x/4 - 9
This expression is at least 42,
∴ 3x/4 - 9 ≥ 42
3x - 36 ≥ 168
3x ≥ 168 + 36
3x ≥ 204
x ≥ 68

To verify the given identity sec(beta) - 1 / cos(beta) = sec(beta), we need to manipulate the left side of the equation to match the right side. By simplifying the expression step by step and using trigonometric identities, we can show that the given equation is true.
To verify the given identity sec(beta) - 1 / cos(beta) = sec(beta), we need to manipulate the left side of the equation to match the right side.
- Start by finding the common denominator of the fractions on the left side, which is cos(beta).
- The expression becomes (sec(beta) - 1)/cos(beta).
- Next, simplify the numerator: sec(beta) - 1 = (1/cos(beta)) - 1 = (1 - cos(beta))/cos(beta).
- Substituting this back into the original expression, we have (1 - cos(beta))/cos(beta) / cos(beta).
- Simplify further by multiplying the numerator and denominator by cos(beta) to get (1 - cos(beta))/(cos^2(beta)).
- Using the identity sec^2(beta) = 1 + tan^2(beta), we rewrite cos^2(beta) = 1 - sin^2(beta) as 1/(1 - sin^2(beta)).
- Therefore, (1 - cos(beta))/(cos^2(beta)) = (1 - cos(beta))/(1 - sin^2(beta)) = sec(beta).
Thus, we have verified that sec(beta) - 1 / cos(beta) = sec(beta).
