15. n - 6 = 21......add 6 to both sides
    n = 21 + 6
    n = 27

16. p + 1 3/4 = 4 5/8...turn mixed numbers to improper fractions
     p + 7/4 = 37/8....there is 2 ways to continue from here...I will show u            both

(1) p + 7/4 = 37/8....multiply everything by common denominator of 8, this gets rid of the fractions.
8p + 14 = 37 (result of multiplying by 8)
8p = 37 - 14
8p = 23
p = 23/8

(2) p + 7/4 = 37/8...subtract 7/4 from both sides
      p = 37/8 - 7/4...common denominator is 8
      p = 37/8 - 14/8
      p = 23/8

either way u use, u will arrive at the same answer

The graph shows the functions f(x), p(x), and g(x):
Kruka [31]
Two functions have equal values where their graphs cross.

A) The solution to the pair of equations
.. y = p(x)
.. y = f(x)
will be where the graphs intersect, at (x, y) = (-3, -3).


B) We already know that (-3, -3) is one solution to y=f(x). The graph also appears to go through the point (0, 0).


C) p(x) = g(x) where their graphs cross, at x = -6. Both functions have the value 1 for that value of x.

Professor Goodheart has two exams, exam 1 and exam 2. The exam 1 weights 40% and the exam 2 weights 60% of the final grades. Put
garri49 [273]

Answer:

Imperfect substitutes

explanation:

The choices above are not perfect substitutes, meaning they can not be perfectly or directly replace the other. Imperfect substitutes are close substitutes but not perfect substitutes. Unlike perfect substitutes, imperfect substitutes satisfies same utility but has different characteristics and therefore not entirely substitutable. For example, while one may want to have the 40 marks too, he'd rather have 60 marks even if the criteria for a 60 mark score was increasingly hard.

What is the exponential form of the following expression? (-5)(-5)(-5) . c . c .c
andrew-mc [135]

Answer:

(-5)^3 * c^3

Step-by-step explanation:

Given

(-5)(-5)(-5) * c * c * c

Required

The exponent form

We have:

(-5)(-5)(-5) * c * c * c

Apply the following law of indices;

x * x * x ...... = x^n

So, the expression becomes:

(-5)^3 * c^3

(MC 02.03) If parallelogram ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A
Soloha48 [4]

A' would lie on point A (-4 , 1)

Step-by-step explanation:

Let us revise some transformations

1. If point (x , y) reflected across the x-axis , then its image is (x , -y)

2. If point (x , y) reflected across the y-axis , then its image is (-x , y)

3. If point (x , y) rotated about the origin by angle 180°, then its image

    is (-x , -y)

Parallelogram ABCD was reflected over the y-axis, reflected over the

x-axis, and rotated 180°

We need to know where would point A' lie

∵ The coordinates of point A are (-4 , 1)

∵ The parallelogram is reflected over x-axis

∴ The sign of y-coordinate of point A changed to opposite

∴ The image of point A is (-4 , -1)

∵ The parallelogram then reflected over the y-axis

∴ The sign of x-coordinate of point (-4 , -1) changed to opposite

∴ The image of point (-4 , -1) is (4 , -1)

∵ The parallelogram then rotated 180°

∴ The signs of the x-coordinate and the y-coordinate of point (4 , -1)

   changed to opposite

∴ The image (4 , -1) is (-4 , 1)

∴ A' is (-4 , 1)

∵ Point A is (-4 , 1)

∴ A' would lie on point A

A' would lie on point A (-4 , 1)
