The one on the left because there cannot be two different y values within one x value
The number (or expression) in the parenthesis is what you would plug into x for the given equations. for example f(3)=4(3)=2 and solve
Answer:
1. n= 14
2. n=3
Step-by-step explanation:
For the first problem, let's break down the equation. The number being thought about can be represented by <em>n</em>. Then <em>n </em>is increased by 7, or simply put 7+ <em>n. </em>The sum is 21, so to find n you can use the equation 7 + n = 24 and solve for <em>n, </em>which is 14.
For problem two, the same strategy can be used. The number is <em>n, </em>multiplied by 9. So, 9 * <em>n</em> is equal to 27. Solve for n by isolating n, and the answer is 3.
The slope is (B) -5/4.

What is a slope?</h3>
- The slope is the inclination of a line relative to the horizontal as a numerical value.
- The slope of any line, ray, or line segment in analytic geometry is the ratio of the vertical to the horizontal distance between any two points on it ("slope equals rise over run").
To find the slope:
- We're going to assume that we don't mean, y = 45x -3; which has a perpendicular line with a slope of -1/45.
- Rather, we're going to assume that we mean, y = 4/5x -3; so that the slope of the perpendicular line is -5/4.
- Similarly, we're going to assume that the answer choices are supposed to represent fractions so that the above slope matches choice B.
- If the slope of a line is m, the slope of the perpendicular line is -1/m.
- The reciprocal of a fraction is the fraction that has the numerator and denominator swapped, -1/(4/5) = -5/4.
Therefore, the slope is (B) -5/4.
