Given f (20) = 5, find x if f(x) = -3x – 4
-3
-19
O 11
O 12
help
Answer:
-19
Step-by-step explanation:
[tex]f(x) = 5 , f(x) = -3x-4[/tex]
We just have to plug in 5 into f(x) and solve for y
[tex]f(5) = -3(5) - 4 \\f(5) = -15 - 4 \\f(5) = -19[/tex]

Zoey signed up for a streaming music service that costs $7 per month. The service allows Zoey to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $0.75 per song. How much total money would Zoey have to pay in a month in which she downloaded 45 songs? How much would she have to pay if she downloaded s songs?
Answer:
the answer is 60 $ but with the charge of 7 its 67.
Step-by-step explanation:
45 divided by 0.75 is 60.
Answer:
Cost for 45 songs: 40.75
Cost for s songs: 0.75s + 7
Step-by-step explanation:
Since its $0.75 per song, you have to multiply 0.75 to 45. You already need to pay $7. The equation would be 0.75s + 7 and the answer would be 40.75.

How can you use unit rates to solve pricing problems?
Answer:
a ratio is a comparison of two numbers or measurements
the objects being compared are called the terms of the ratio.
if the tow terms are different units this is called a rate.
example:
David covers 600 miles in 8 hours and John covers 380 miles in 5 hours. Who is driving faster ?
solution:
Distance covered by David in 1 hour is
= 600 / 8
= 75 miles per hour
Distance covered by John in 1 hour is
= 380 / 5
= 76 miles per hour
When we compare the above unit rates (Distance covered in 1 hour), John is driving faster than David.
We can use unit rates to solve pricing problems because we solve for price of one of that item.
For example, David bought 5 pounds of peanuts for $10, how much does it cost for one pound?
10 / 5 = $2 per pound
The $2 is the unit rate and we use to find if David buys more then 10 pounds.
Best of Luck!
15. If gasoline costs $4.02 per gallon, your tank holds 13 gallons, and your car averages 26 miles per gallon,
a) If your tank is full, how far can you drive before you run out of gas?
b) If your tank were empty, how much will it cost to fill up your tank?
Answer: a) 338 miles
b) $52.26
Step-by-step explanation: To get the amount of miles that your car can drive before running out of gas, you just multiply how many gallons you have by how many miles each gallon lasts. Then, to get the cost of all the gas, you multiply the cost of the gas by how many gallons you need.

Answer:
x=16
Step-by-step explanation:
I hope this helped
Answer:
x= 1/6
Step-by-step explanation:
1) Add the same term to both sides of the equation
2/x+1=3/x-5
2/x+1-1=3/x-5-1
2) Simplify-Add the numbers
2/x=3/x-6
3) Multiply all terms by the same value to eliminate fraction denominators
4) Simplify
5) Add the same term to both sides of the equation
6) Simplify
7) Divide both sides of the equation by the same term
8) Simplify
1/6=x

Answer:
x = - 2.5, 1
Step-by-step explanation:
In the given figure, JM and JK are the tangents drawn from the external point J to the [tex] \odot[/tex] L, Points K and M are points of tangency.
Since, tangents drawn from external point to a circle are congruent.
[tex]\therefore JM = JK\\\therefore 2x^2 +3x - 2 = 3\\\therefore 2x^2 +3x - 2 -3=0\\\therefore 2x^2 +3x - 5 =0\\\therefore 2x^2 - 2x + 5x - 5 =0\\\therefore 2x(x - 1) + 5(x - 1) =0\\\therefore (x - 1) (2x+ 5) =0\\\therefore x - 1 = 0\: or \: 2x + 5= 0\\\therefore x = 1\: or \:2x = - 5\\\therefore x = 1\: or \:x = - 2.5\\\huge \purple {\boxed {\therefore x = \{-2.5,\: 1\}}}[/tex]
Are the lines parallel, perpendicular, or neither
Answer:
perpendicular
Step-by-step explanation:
The first equation can be written in slope-intercept form as ...
y = -1/2x - 3
In this form, we see that the slopes of the two lines are -1/2 and 2, so the product of their slopes is -1. That means the lines are perpendicular.

What is the value of -2/5 divided by 3/4
Answer:
[tex]-\frac{8}{15}[/tex]
Step-by-step explanation:
To divide a fraction by another fraction, you flip the second fraction and also change the divide sign to a multiply sign.
[tex]-\frac{2}{5}\div \frac{3}{4}=-\frac{2}{5}\times \frac{4}{3}[/tex]
Multiply:
[tex]-\frac{2\times \:4}{5\times \:3}[/tex]

-2(x-3) < 2x - 4
Answer:
2.5 < x or 5/2 < x
Step-by-step explanation:
Start by distributing the -2 to the parenthesized numbers.
-2*x and -2*-3
You end up with -2x and 6 (negative times a negative gets positive).
-2x+6 < 2x-4
Next you need to get your variables, x, on one side. It can be either but I like addition so lets take the -2x and move it to the opposite side.
You'll need to add 2x to both sides since its a negative number.
-2x(+2x)+6 < 2x(+2x)-4
-2+2 is 0 and 2+2 is 4.
6 < 4x-4
You want to get the variable alone now so you'll want to add the 4 to the other side (because its negative you add. If it was positive you'd subtract).
6(+4) < 4x-4(+4)
6+4 is 10 and -4+4 is 0.
10 < 4x
You want to divide out the 4 from 4x because you want the variable alone. Divide 4 from both sides
10(/4) < 4x(/4)
Now depending on if you want a variable or a fraction 10/4 can be 5/2 (simplified fraction) or 2.5 (decimal). 4x/4 gives you x.
2.5 (or 5/2) < x
Hope that helps.
would you classify the number 200 as a perfect square, a perfect cube,both, or neither? explain
A: No, the number 200 is not a perfect square.
B: No, the number 200 is not a perfect cube.
C: Yes. the number 200 is neither.
No number times itself twice or threefold is 200 therefore I can conclude it's neither.
Answer: neither because a perfect square is number like 9 or 100 where 3^2=9 and 10^2=100 and likewise for a perfect cube. 200 is not a perfect square or perfect cube for any number
