what is the solution for 11 = y-6
Answer:
y = 17
Step-by-step explanation:
11 = y - 6
11 + 6 = y17 = yprove that the value of y is 17
11 = y - 6
11 = 17 - 611 = 11proven
Hello.
Let's solve this equation for y.
First, subtract 11 from both sides:
[tex]\mathrm{11-11=y-6-11}[/tex]
[tex]\mathrm{0=y-6-11}[/tex]
[tex]\mathrm{0=y-17}[/tex]
Subtract y from both sides:
[tex]\mathrm{-y=-17}[/tex]
[tex]\Large\boxed{\sf{y=17}}[/tex]

i once met six siblings whose ages are 6 consecutive whole numbers. i asked each of them the question how old is your oldest sibling. which of the following could not be the sum of their answers.
A. 95
B. 125
C. 167
D. 205
E. 233
The consecutive ages of the siblings mean that each sibling is a year older than the younger sibling
All the options cannot be the sum of their ages
How to determine the sum of their ages
Represent the age of the smallest sibling with x.
So, the sum of their ages is:
[tex]Sum =x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5[/tex]
Evaluate the like terms
[tex]Sum =6x + 15[/tex]
When the sum is 95 (from the options), we have:
[tex]6x + 15 = 95[/tex]
Subtract 15 from both sides
[tex]6x = 80[/tex]
Divide by 6
[tex]x = 13.3[/tex] -- this is not an integer
When the sum is 95 (from the options), we have:
[tex]6x + 15 = 125[/tex]
Subtract 15 from both sides
[tex]6x = 110[/tex]
Divide by 6
[tex]x = 6.875[/tex] -- this is not an integer
When the sum is 167 (from the options), we have:
[tex]6x + 15 = 167[/tex]
Subtract 15 from both sides
[tex]6x = 152[/tex]
Divide by 6
[tex]x = 25.33[/tex] -- this is not an integer
When the sum is 205 (from the options), we have:
[tex]6x + 15 = 205[/tex]
Subtract 15 from both sides
[tex]6x = 190[/tex]
Divide by 6
[tex]x = 31.67[/tex] -- this is not an integer
When the sum is 233 (from the options), we have:
[tex]6x + 15 = 233[/tex]
Subtract 15 from both sides
[tex]6x = 218[/tex]
Divide by 6
[tex]x = 36.33[/tex] -- this is not an integer
Hence, all the options cannot be the sum of their ages

Solve the equation by using the quadratic formula.
3x² - 1 = 7x
Answer:
Solutions: [tex]\displaystyle\mathsf{x\:=\:\frac{7+ \sqrt{61}}{6}}[/tex] , [tex]\displaystyle\mathsf{x\:=\:\frac{7 - \sqrt{61}}{6}}[/tex]Step-by-step explanation:
We are given the following quadratic equation, 3x² - 1 = 7x, which requires us to find its possible solutions using the quadratic formula.
Definitions:In a quadratic equation, the leading term has a second-degree (or squared) variable. The standard form of a quadratic equation is ax² + bx + c = 0, where a, b, and c are real numbers, and that a ≠ 0. Quadratic Formula:The quadratic formula is given by:
[tex]\displaystyle\mathsf{x\:=\:\frac{-b\pm\sqrt{b^2-4ac}}{2a}}[/tex]
We will use this formula to solve for the roots or the solution of the given quadratic equation.
Solution:Step 1: transform the given equaton into standard form.
First, we must subtract "7x" from both sides of the equation:
3x² - 7x - 1 = 7x - 7x
3x² - 7x - 1 = 0 ⇒ This is the standard form of the given quadratic equation where a = 3, b = -7, and c = - 1.
Step 2: Plug in the values for a, b, & c into the quadratic formula.
The derived values for a, b, & c from the previous step are: a = 3, b = -7, and c = - 1. Substitute these values into the following quadratic formula:
[tex]\displaystyle\mathsf{x\:=\:\frac{-b\pm\sqrt{b^2-4ac}}{2a}}[/tex]
[tex]\displaystyle\mathsf{x\:=\:\frac{-(-7)\pm\sqrt{(-7)^2-4(3)(-1)}}{2(3)}}[/tex]
Step 3: Following the PEMDAS Order of Operations, start by applying the Power rule of Exponents [tex]\displaystyle\mathsf{(a^m)^n = (a^{m*n})}[/tex] (under the radical) :
[tex]\displaystyle\mathsf{x\:=\:\frac{-(-7)\pm\sqrt{49-4(3)(-1)}}{2(3)}}[/tex]
Step 4: Next, multiply the integers under the radical, PEMDAS Order of Operations.
[tex]\displaystyle\mathsf{x\:=\:\frac{-(-7)\pm\sqrt{61}}{2(3)}}[/tex]
Step 5: Multiply the integers in the denominator, and apply the multiplication integer rule, -(-a) = a.
[tex]\displaystyle\mathsf{x\:=\:\frac{7\pm\sqrt{61}}{6}}[/tex]
Since [tex]\displaystyle\mathsf{\sqrt{61}}[/tex] is not a perfect square, it can remain the same.Step 6: Separate the solutions.
[tex]\displaystyle\mathsf{x\:=\:\frac{7+ \sqrt{61}}{6}}[/tex] , and [tex]\displaystyle\mathsf{x\:=\:\frac{7 - \sqrt{61}}{6}}[/tex]
Final Answer:Therefore, the solution to 3x² - 1 = 7x are: [tex]\displaystyle\mathsf{x\:=\:\frac{7+ \sqrt{61}}{6}}[/tex], [tex]\displaystyle\mathsf{x\:=\:\frac{7 - \sqrt{61}}{6}}[/tex].

4,000 i savings at end of 3 years earn 960 in simple interest how much in account
Answer:
She would have had $120 more should the rate were 1% greater.
Step-by-step explanation:
At the end of 3 years the amount in the account = Principal + Interest
Amount = 4000 + 960 = 4960
Amount at the end of 3 years = $4960
b) Formula for Rate , R = 100I/(PT)
Where I = Interest = 960, P = Principal = 4000, T= Time = 3 years
R = (100 × 960) / ( 4000 × 3)
R = 8
Rate, R = 8% per annum.
c) If the rate was 1% more, R = 8 + 1 = 9% per annum
Interest, I = PRT/100
Interest, I = 4000 × 9 × 3 /100 = 1080
Amount in her account would have been = $4000 + $1080 = $5080
Amount more = $5080 - $4960 = $120

First, create 3 equations of the form ax+by+cz=d , where a, b, c, and d are constants (integers between – 5 and 5). For example, x+2y-z=-1 . Perform row operations on your system to obtain a row-echelon form and the solution.
Go to the 3D calculator website GeoGebra: www.geogebra.org/3d?lang=pt and enter each of the equations.
After you have completed this first task, choose one of the following to complete your discussion post.
1. Reflect on what the graphs are suggesting for one equation, two equations, and three equations, and describe your observations. Think about the equation as a function f of x and y, for example, x+2y+1=z in the example above. Geogebra automatically interprets this way, that is, like z=f(x, y)=x+2y+1 , it isolates z in the equation.
Answer:
The solution is x=0, y=0, z=1
Step-by-step explanation:
Step1: -row2 + row1; -row2 + row3

An ordinary (falr) dle is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a dle is rolled twice in succession
and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 8.
Event B: The sum is divisible by 5.
Write your answers as fractions.
(a) P(X) =
(b) P(B) =
By finding the number of outcomes that meet each criteria, we will see that the probabilities are:
A) P = 0.25B) P = 7/36 = 0.194How to find the probability?
We know that the fair die has 6 outcomes, so if we roll it twice, there are a total of:
6*6 = 36 outcomes.
To find the probability of getting a given event, we need to find the number of outcomes that make the event true.
A) The sum is greater than 8.
The outcomes that make this true are:
first roll second roll sum
4 5 9
4 6 10
5 5 10
5 6 11
6 3 9
6 4 10
6 5 11
6 6 12
3 6 9
So there are 9 outcomes whose sum is greater than 8, so the probability to getting this event is:
P = 9/36 = 0.25
B) The sum is divisible by 5.
The sum must be 5 or 10, the outcomes that give that are:
first roll second roll sum
1 4 5
2 3 5
3 2 5
1 4 5
4 6 10
5 5 10
6 4 10
There are 7 outcomes, so the probability is:
