1/2x - 1 = 4 whats the solution?
Answer:
To solve for x, isolate it from the other terms.
Add 1 to both sides.
1/2x - 1 + 1 = 4 + 1
Combine like terms.
1/2x = 5
Multiply both sides 2.
x = 5(2)
x = 10
The solution is 10.

Prove that y = arcsinx on the root of 1 x squared satisfies the equality (1 - x squared)y' - xy = 1
Answer:
Step-by-step explanation:
The first part is a computation, combining the chain and quotient rules. We know that the derivative of f(x)=arcsin(x) is 1/sqrt(1-x2), and we need to differentiate the denominator. We use the chain rule: let u=1-x^2, and v=sqrt(u). Then du/dx=-2x, and dv/du = 1/(2 sqrt(u)). Combining, dv/dx=-x/sqrt(1-x2). Now, we put everything together using the quotient rules: y' = (f'v-v'f)/v2. Multiplying by (1-x2)=v2, we obtain (1-x2)y'= sqrt(1-x2)/sqrt(1-x2) +xarcsin(x)/sqrt(1-x2), which we can rewrite as 1+xy, as desired. Let's call this equation ().
We prove the second part by induction on n. To do this, we need two things: a base case, that is, proving the case n=0, and an inductive step, where we prove case n+1 from case n. To do the base case, we differentiate both sides of equation (*) that we proved above: d/dx ((1-x2 )y') = d/dx (xy+1 ). On the left-hand side, we get -2xy'+(1-x2 )y'', using the product rule, and on the right-hand side, we get xy'+y, similarly. Rearranging, we've proven the case n=0 of the desired statement. The inductive step is similar: we differentiate the equation from case n using the chain rule. Each of the first two terms splits into two: respectively, -2xy(n+2)+(1-x2)y(n+3), and (2n+3)y(n+1)+(2n+3)xy(n+2). If we combine the terms with the same numbers of derivatives on y, we get (1-x2)y(n+3)-(2n+5)xy(n+2)-((n+1)2+2n+3)y(n+1)=0 -which is what we wanted to prove, since ((n+1)2+2n+3) simplifies to (n+2)2.

How do I point 11,7 on the coordinate plane
Answer: Plot a point on a coordinate plane just remember that the coordinate given is of the form . Follow this simple steps
Step-by-step explanation: Identity the variable range .
Determine the scale of the graph.
Number and label each axis and title of the graph.
Show the positive and negative x-axis and y-axis
First , find the value of x on the x-axis . give x = 11 .
Find the value of y on the y-axis . given y = 7.
Mark the point x=11 in the positive x - axis
Mark the point y=7 in the positive y - axis,.
After this meet the points by the help of scale and write the co-ordinates.

https://brainly.in/question/10164601
When you're asked to plot a point on a coordinate plane just remember that the coordinate given is of the form .
So, first, we need to plot 11 on the -axis (the line going left to right, horizontal) then plot 7 on the -axis (the vertical line)
So we first go 11 units to the right along the -axis then go up 7 units along the -axis.

Answer:
-5x + 16
Step-by-step explanation:
I didn't see a equal sign so I assume that x cannot be x = -5/16
So I combined like terms of x and -6x to get -5x as well as +6 and +10 to get 16.
To get my final answer as -5x + 16.

1. “Zoe and Toria are going into business. They need 80,000 to start the business. Their investment is 3:5, respectively.
a. What's Zoe & Ares individual investment amounts?
b. What percent did each person invest?
9514 1404 393
Answer:
a. Z: 30,000; T: 50,000
b. Z: 37.5%; T: 62.5%
Step-by-step explanation:
a. The "ratio units" add up to 3+5 = 8, so we can find the investment amounts by multiplying the ratio by 10,000
Z : T = 3 : 5 = 30,000 : 50,000
Zoe invested 30,000Toria invested 50,000__
b. Zoe's investment amount is 3/8 of the total, or ...
3/8 × 100% = 37.5%
Toria's percentage is the rest of it:
100% -37.5% = 62.5%
Zoe invested 37.5% of the total; Toria invested 62.5% of the total.

when you answer the question plz put it how i seated put with the answer next to them with the answer just put one of them
The number of days that it will take Oliver and Eva to be on the same page of the book is 11 days.
Oliver's equation = 43 + 3tEva's equation = 21 + 5tBased on the information given, the equation to solve the question will be:
43 + 3t = 21 + 5t

My mom gave me $20 for grocery’s. She needed cat food which was $8.50 for a 35 pound bag. And the rest of the money she needed to buy socks for my dad which are a $1.50 for two pairs how many pairs of socks can I buy.
Answer:
15 pairs
Step-by-step explanation:
total:$20
cat food: $8:50
two pair of socks: $1.50
$20 - $8.50= $11.50(the rest of the money)
the rest is divided by the price of the socks to obtain how may socks you can pay with $11.50.
$11.50÷$1.50≈ 7.6
Now you multiply 7.6 by two to get the exact amount of socks with the offer.
7.6×2≈15.2
15.2≈15
So with $11.50 you will buy 14 socks for 1.50 every two pairs and a pair for 0.75

Bryce has $16 more than Corey. Both have a combined total of $50. How much money does Bryce have.
Answer:
$33
Step-by-step explanation:
Let the amount of money Corey has be $x.
Amount of money Bryce have= $(x +16)
Total amount= $50
$x +$(x +16)= $50
2x +16= 50
2x= 50 -16
2x= 34
Divide both sides by 2:
x= 34 ÷2
x= 17
Amount of money Bryce have
= $(17 +16)
= $33

Answer: 50%
Step-by-step explanation:
In the base ten number 4325 , how many times
greater than the value represented by the digit 2 is the value represented by the digit 4 ?
Using the concept of place value, the digit 4 is 200 times greater than the digit 2.
Given the number :
4325The digit 2 is in the tens place = 2 × 10 = 20
The digit 4 is in the thousand place = 4 × 1000 = 4000
The number of times greater can be obtained thus :
4000 / 20 = 200Hence, the digit 4 is 200 times greater than the digit 2.
