help me guys and it will be better if you also write the explaination
Answer:
Please see below.
Step-by-step explanation:
f^-1 (x) essentially means the reverse.
We can substitute y for x in the equation and solve for y:
x = 4y -1
x+1 = 4y
y = (x+1)/4
so that is our answer for the first one:
f^-1(x) = (x+1)/4
We do the same trick for the second question:
x = 2y +1
x-1 = 2y
y = (x-1)/2
so the answer is f^-1(x) = (x+1)/2
The last question is slightly more complex, we can write is as:
x = 2y/(y-1)
x(y-1) = 2y
yx -x = 2y
yx = 2y + x
yx - 2y = x
y(x-2) = x
y = x/(x-2)
so the answer is x/(x-2)

Hi there!
The two pictured angles are vertical angles, making them congruent. Thus:
(5x + 4)° = 39°
Solve for x:
5x = 39 - 4
5x = 35
x = 35/5
x = 7°
How many times longer does it take light from the Sun to reach Neptune than Mercury? Express this number in standard notation. Explain your reasoning
Answer:
Step-by-step explanation:
The ratio of light times will be the ratio of distances:
(light time to Neptune) / (light time to Mercury)
= (Neptune distance)/(Mercury distance)
= (27.93×10^8 mi)/(0.3598×10^8 mi) = 27.93/0.3598

some friends played a board game. during the game, one unlucky player had to move back 7 spaces 5 turns in a row
Answer:
35
Step-by-step explanation:
M(2,4) is the midpoint of RS. The coordinates of S are (3,1) what are the coordinates of R
1, 7
just do
3, 1
2, 4
and see what you have to do to get to that mid point. you need to go down one to get to 2 from 3 and you have to go +3 to get to 4 from 1. so you need to go down 1 for x and + 3 for y
hope that made sense

The points H, I, J and K all lie on the same line segment, in that order, such that the
ratio of HI: IJ: JK is equal to 2:1: 2. If HK = 25, find JK.
Step-by-step explanation:
Given,
ratio of HI, IJ , Jk = 2 : 1 : 2
let their value be
HI = 2x
IJ = x
JK = 2x
HK = 25
according to question,
HI + IJ + JK = Hk
now, after inserting the values we got,
→ 2x + x + 2x = 25
→ 5x = 25
→ x = 25/5 = 5
→ x = 5
therefore value of,
HI = 2x → 2×5 = 10
IJ = x → 5
JK = 2x → 2×5 = 10
Hence, value of JK is 10.
hope this answers helps you dear...take care and may u have a great day ahead!

For what value of x is line f parallel to line g?
Answer:
Line f and line G have the same slope, so they're parallel. So x is the slope
Step-by-step explanation:
Line f and line G have the same slope, so they're parallel. So x is the slope
20) Three consecutive odd numbers sum to 315. Write an equation and solve for the first number, then list all three numbers.
someone please help
Answer:
Step-by-step explanation:
I don't do this question the same way as it is done in the classroom, but I will get you the right answer
Let the middle number = x
Let the smallest number = x - 2
Let the largest number = x + 2
x - 2 + x + x + 2 = 315 Combine like terms. The 2s cancel
3x = 315 Divide by 3
x = 105
So the middle number is 105
The smallest number is 103
The largest number is 107
Total 315
This method cuts out at least one step. It works best with an odd number of terms. If you have an even number, you have to use the more traditional method.

If l || m, find the value of y.
Answer: y = 50
Step-by-step explanation:
Supplement angles are two angles that sums up to 180°. So we could interfere that (8x - 14)° and (5y + 16)° are supplement angles. But before we move on, we should first solve for x. Opposite angles are equal. So therefore the angle opposite to 8x - 14 is also equal to 8x - 14. Guess what? Corresponding angles are also considered equal. So we could then conclude as following:
5x + 34 = 8x - 14
With the equation above we can now solve for x. We first add 14 on both sides.
5x + 48 = 8x
We then substract 5x on both sides.
48 = 3x
We finally divide 3 on both sides. This gives us the value of x.
x = 16
Now that we know the value of x, we could now solve (8x - 14)°. We first start by substituting in the equation.
8(16) - 14
We then multiply 8 with 16.
128 - 14
We finally substract 14 from 128. This gives now the value of the angle
114°
Now that we know this, we could now solve for y. Like I said earlier, supplement angles add up to 180°. So our equation should go as following:
114 + (5y + 16) = 180
We first add like terms together.
5y + 130 = 180
We then substract 130 on both sides
5y = 50
We finally divide 5 on both sides of the equation.
y = 50

f(x) = (x + 5)(x + 3)(x - 2)2
Answer:
if you learned derivative:
f'x=(x+3)(x-2)²+(x+5)(x-2)²+2(x+5)(x+3)(x-2)

⇒x=2; =-0.84; =-4.16
⇒fx=0; =72.47; -36.97⇒fx contain (2;0); (-0.84;72.47); (-4.16;-36.97)
if x=0⇒f'x=-28<0⇒from -0.84 to 2, fx Decreasing

Carly and James share some money in the ratio 5:3
Carly gets £70 more than James.
Answer:
Okay - so what you would do is:
5:3 - Carly gets 2 more than James.
2 = 70£
70/2 = 35
1 = 35£
which means that Carly has 175£ while James has 105£.
Find x. Round your answer to the nearest hundredth.
25
x

30m of material costs £210.how much would 18 m of this material cost?
Step-by-step explanation:
given,
30m of material cost = £210
so, cost of 1m material = 210/30 = £7
therefore, cost of 1m material is £7
now,
cost of 18m Material = 18 × 7 = 126
therefore, cost of 18m material is £126.
hope this answer helps you dear!
Answer: 126
Step-by-step explanation:
30 m of material cost 210
1 m of material cost [tex]\frac{210}{30}[/tex] Or 7
18 m of material cost 7 × 18 = 126

A barber charges \$12$12dollar sign, 12 for a haircut. His operating expenses are, on average, \$37$37dollar sign, 37 per day. He calculates his profit by subtracting his operating costs from the money he earns from the haircuts he gives. In a given day, the barber expects to make a profit of at least \$86$86dollar sign, 86. If the barber gives hhh haircuts in a day, which inequality best models this situation
Answer:
12h-37 >/ 86
Step-by-step explanation:
so basically the barber wants to make a profit of 86 dollars since profit is total revenue minus expenses then we know that the barber total revenue is 12h and the expenses for the day are 37.
Please help!!! ASAP!!
Step-by-step explanation:
the total length of all lines is 100.
there are 2 times a d line, and 5 times an x line.
well, what we have here is an equation :
2d + 5x = 100
2d = 100 - 5x = 5×(20 - x)
d = 5/2 × (20 - x) = 50 - 5x/2
