Answer:
[tex]k = 9\frac{3}{5},\: k = - 8[/tex]
Step-by-step explanation:
[tex] |5k - 4| + 2 = 46 \\ \\ \implies \: |5k - 4| = 46 - 2 \\ \\ \implies \: |5k - 4| = 44 \\ \\\implies \: 5k - 4 = \pm \: 44 \\ \\\implies \: 5k - 4 = 44 \: \: or \: \:5k - 4 = - 44 \\ \\\implies \: 5k = 44 + 4 \: \: or \: \:5k = - 44 + 4\\ \\\implies \: 5k = 48 \: \: or \: \:5k = - 40\\ \\\implies \: k = \frac{48}{5} \: \: or \: \:k = \frac{ - 40}{5} \\ \\\implies \: k = 9\frac{3}{5} \: \: or \: \:k = - 8\\ \\[/tex]
( How far does the tip of the minute hand of a clock move in 20 minutes if the hand is 5 inches long
Answer:
3 1/3 pi inches
Step-by-step explanation:
since we know that when 20 minutes have passed, the minute hand will have moved 4 intervals (i.e. from 12 to 4), and each interval is 30 degrees by measurement. So 4 intervals have a degree measurement of 120 degrees, which is 1/3 of the whole circle (clock). since there isn't any notation on whether pi is taken as 3.14 or 22/7 or whatsoever, you can just say that it has moved (5x2)pi x 1/3 = 3 1/3 pi inches
What is Y + 4 = -3 (x +1) in standard form?
Answer:
-3x - y = 7
first, distribute -3:
y + 4 = -3x - 3
then get x and y on the same side and the number on the other side for standard form.
add 3 to both sides:
y + 7 = -3x
subtract y from both sides:
7 = -3x - y

Pedro signed up for a streaming service that cost 13$ per month. The service allows Pedro to listen to unlimited music, but if he wants to download songs for offline listening, the service charges $0.75 per song. how much total money would Pedro have to pay in a month in which he downloaded 45 songs? How much would he have to pay if he download s songs?
Answer:
46.75 dollars and 13 + 0.75s = x
Step-by-step explanation:
13+.75S=Monthly payment
13+.75(45)=46.75
If he downloaded 45 songs he would pay 46.75 dollars
If he downloaded S songs he would pay 13 + 0.75s = x

Determine the function which corresponds to the given graph. The asymptote is x = -1.
Answer:
y = log(x + 1)
Step-by-step explanation:
Given graph represents a logarithmic graph.
Let the equation of the graph is represented by the logarithmic graph,
y = log(x + b)
This graph passes through origin (0, 0),
For the given point (0, 0),
0 = log(0 + b)
log(1) = log(b)
b = 1
Therefore, the function that corresponds the graph will be,
y = log(x + 1)

Rectangle LMNP with vertices L(-2, 7),
M(2,3), N(0, 1), and P(-4, 5):
(a) Translation: (x, y) - (x + 6, y-8)
(b) Reflection: in the y-axis
Answer:
L’ is (-4,-1)
M’ is (-8,-5)
N’ is (-6,-7)
P’ is (-2,-3)
Step-by-step explanation:
Here, we want to from new vertices by translation followed by reflection;
When we reflect , we simply change the sign of the x-coordinates if we are reflecting over the y-axis
We proceed as follows;
1. L (-2,7)
Translation will be (-2 + 6, 7-8) = (4,-1)
Reflection will be ( -4,-1)
so L’ is (-4,-1)
2. M (2,3)
Translation will be
(2 + 6, 3-8) = (8,-5)
Reflection will be ( -8,-5)
So M’ is (-8,-5)
3. N (0,1)
translation will be
( 0 + 6, 1-8) = (6,-7)
Reflection will be ; (-6,-7)
4.P (-4,5)
Translation will be (-4 + 6, 5-8)
= (2, -3)
Reflection will be;
(-2, -3)
P’ = (-2,-3)

Answer:
A.the first one B.the second one C. the second one
Step-by-step explanation:
A. 17*10 to the power of 8 is just adding 8 zeros so it would be 1700000000 and the other is 400000000 so clearly 17 one is greater
B. 2000000 or 7839000 the second one is bigger
C. 420000000 or 850000000 the second one is bigger

Under her cell phone plan, Janelys pays a flat cost of $46.50 per month and $5 per gigabyte. She wants to keep her bill under $70 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Janelys can use while staying within her budget.
Answer:
less than 4.7 gigs
Step-by-step explanation:
The cost of Janelys's cell phone plan will be the sum of the flat cost and the product of the per-gig cost and the number of gigs of data she uses.
y = 46.50 +5g
She wants this to be less than $70 per month, so we can find the constraint on her data usage from ...
46.50 +5g < 70
5g < 23.50 . . . . . . . . subtract 46.50
g < 4.7 . . . . . . . . . . divide by 5
Janelys must use less than 4.7 gigs of data to stay within her budget.

0.6 can be written in fractions form as;
[tex]0.6 = \frac{6}{10} [/tex]
By simplifying the numeration and denominator by 2, you get;
[tex] \frac{3}{5} [/tex]
Now that we have common denominators we can compare both fractions and say that the one with the higher denominator is larger, Hence=
[tex] \frac{4}{5} > \frac{3}{5} [/tex]
[tex] \frac{4}{5} > 0.6[/tex]
Answer:
4/5 > 0.6
Step-by-step explanation:
Given into Decimal:
4/5 = 0.8
Thus, 0.8 > 0.6
Hence, Answer = 4/5 > 0.6
