Answer:

-3

Step-by-step explanation:

4^x = (1/8)^(x+5)

(2^2)^x =  (2^-3)^(x+5)

2^2x = 2^(-3x - 15)

Since both sides have the same base of 2, then the exponents are equal

So

2x = - 3x - 15

5x = -15

 x = -3

Mars2501 [29]

Answer:

a) n=\frac{d+2}{4}

b)

When d = 3

n = (3+2)/4 = 5/4 inches

When d= 6

n = (6+2)/4 = 2 inches

When d = 10

n = (10+2)/4 = 3 inches

Step-by-step explanation:

<u>Complete Question:</u>

<em>The penny size of a nail indicates the length of the nail. The penny size d is given by the literal equation d=4n−2, where n is the length (in inches) of the nail.</em>

<em>a) Solve equation for n</em>

<em>b) Use part (a) to find length of nails with the following penny sizes: 3, 6, 10.</em>

<u>Solution:</u>

<u />

a)

We use algebra and take 2 to the other side and divide to solve for n. Shown below:

d=4n-2\\d+2=4n\\n=\frac{d+2}{4}

So,

n = (d+2)/4

b)

Since we have to find length of nails, we plug in 3, 6, and 10 respectively into d of the formula we found in part (a).

When d = 3

n = (3+2)/4 = 5/4 inches

When d= 6

n = (6+2)/4 = 2 inches

When d = 10

n = (10+2)/4 = 3 inches

Answer:

Step-by-step explanation:

(1) 90 - 22 = 68

(2) 180 - 22 = 158

(3) 90 - 36 = 54

(4) 90

(5)90 - 24 = 66

(6) 24

(7) 15(complimentary angles are equal)

(8)90- 42 = 48

(9) E + F = 180(SUPPLEMENTARY ANGLES); E = 180 - 162 = 18

(10) G + H = 90(complementary angles); H= 90 - 18 = 72

(11)I + J= 180; J= 180 - 18 = 162

(12) K + L = 90; k = 90 - 42 = 48

Please see the question below. Please answer in full. Thanks in advance.
Dahasolnce [82]

y = log base (x - h) + k

1) Vertical Asymptote: -4

The vertical asymptote is at -4 because when dealing with logs, the vertical asymptote will always be the h value, and since in the original equation you are subtracting it from x, you flip the sign, so instead of positive 4, you get negative 4.

2) Domain: x > -4

When graphing a logarithm, it doesn't cross the vertical asymptote, and it is a positive function, so all of the x values will be greater than -4.

3) X and Y Intercepts: x = -2, y = 1

To find the x-intercept, y has to equal 0, so plug 0 in for y and solve for x. To find the y-intercept, x has to equal 0, so plug in 0 for x and solve for y.

4) Transformations: shifted 4 units to the left, and shifted 1 unit up.

To find the horizontal movement, look at h. If h is positive, then the function has been shifted that many units to the left. If h is negative, then the function has been shifted that many units to the right, To find the vertical movement, look at k. If k is positive, then the function has moved that many units up. If k is negative, then the function has moved that many units down.
