Answer:

-y = x-1 is a fairly simple equation at least with real integers.

I hope to help you understand the process of solving it so you can apply the thinking to increasingly difficult equations. If this equation is difficult for you, I will try to explain it simply.

let's try a simple trick. If you want to solve for y, then it's helpful to remove the negative from it.

that means you need to do the same thing to the x side, but since x is already positive it needs to change to -x to balance things out.

the equation now reads y = -x+1 because we have reversed the negative and positive values on both sides of the equation.

I hope this helps simplify the thinking behind solving an equation of this nature. The two previous answers above this one are both correct, but may be just a tad more complex than you need at this moment.

Answer:

i got 8.5

Step-by-step explanation

i have a triangle area calculator lol..

The length of the base of the triangle is B = 8.5 inches

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the area of the triangle be A = 25.5 inches²

Let the height of the triangle be H = 6 inches

Let the base of the triangle be B

Now , area of the triangle = ( 1/2 ) x Length x Base

On simplifying , we get

25.5 = ( 1/2 ) x ( 6 ) x ( B )

On simplifying , we get

3B = 25.5

Divide by 3 on both sides , we get

B = 8.5 inches

Hence , the base of triangle is B = 8.5 inches

Let's first look only at the numerator: 5x^2 - 5

Consider this question: What do both terms have in common?

The answer is 5, both terms contain a 5, so we can factor it out.

5(x^2 - 1)

Now let's look at the denominator, considering the same question: 3x^2 + 3x

This time, both terms contain a 3 and an x.

3x(x^2 + 1)

Now we are here: [ 5(x^2 - 1) ] / [ 3x(x + 1) ]

In the numerator, the binomial factors out into (x + 1)(x - 1). There is also an (x + 1) in the denominator, so those to binomials cancel out. That leaves us with the following expression:

5(x - 1) / 3x

Correct Answer: C

Answer: [tex]f^{-1}(x)=\frac{x-1}{2}[/tex]

Step-by-step explanation:

To find the inverse of a function start by replacing f(x) with x and replace the original x with y.

[tex]f(x)=2x+1\\x=2y+1[/tex]

Now solve for y

[tex]x=2y+1\\x-1=2y+1-1\\x-1=2y\\\frac{x-1}{2} =\frac{2y}{2}\\\frac{x-1}{2} =y[/tex]

Finally, replace y with the inverse of f(x), [tex]f^{-1}(x)[/tex]

Step-by-step explanation:

Well there is no direct formula for calculating the orthocentre

well the process of finding the orthocentre is to find the altitudes of all the sides and then find their intersection points

Here in this question

The given triangle represents a right angled triangle with right angled at L(-3,2)

We know that the ortho centre in a right angled triangle is the right angled vertex

-----------------------------------------------------------------------

Hence the required orthocentre is (-3,2) and it is on the Triangle

The number of different assignments that are possible for this case when the teacher wants to assign 4 of the 15 practice problems is 1,365 ways.

We can use combinations for this case,

Total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total of

[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!}[/tex]  ways.

For this case, the teacher have to choose 4 problems out of 15 practice problems so that assignments are different.

An assignment would be different than other if the 4 questions in one assigment are not exactly same in the second assigment, and their order won't matter (assumingly).(no counter statement is given in the question's statement) against this assumption).

Those 15 problems are assumingly distinguishable (here we used general logic that each problem would be somewhat different if not fully, and thus, no two problems being indistinguishable).

Then, we can use the combinations to find the number of ways any 4 problems out of 15 practice problems available can be chosen, as shown below:

[tex]^{15}C_4= \dfrac{15!}{4! \times (15-4)!}\\\\\\^{15}C_4=\dfrac{15!}{4! \times 11!} = \dfrac{15 \times 14 \times 13 \times 12 \times 11 \times \cdots \times 2 \times 1}{(4 \times 3 \times 2 \times 1) \times ( 11 \times \cdots \times 2 \times 1)}\\\\\\^{15}C_4=\dfrac{15 \times 14 \times 13 \times 12 }{4 \times 3 \times 2 \times 1} = 1365[/tex]

Thus, the number of different assignments that are possible for this case when the teacher wants to assign 4 of the 15 practice problems is 1,365 ways.

The area is 4(x+3). If we multiply the 4 out we have 4x + 12 as the area using the distributive property.

Expression: 4x+12

The original dimensions are x+3 and 4. If they are doubled, we have new dimensions 2x+6 and 8. The area is then 8(2x+6) = 16x + 48.

Area: 16x+48

Explanation: The ratio of the area of the original rectangle to the area of the larger rectangle is and will always be (4x+12)/(16x+48) = 1/4. Therefore, the ratio will be the same for any positive value of x.

Mean is the ratio of the sum of data to the ample size. The remaining four cards that could be on the card are 8, 8, 16 and 22

Mean is the ratio of the sum of data to the ample size. Median is the middle number after rearrangement while the mode is the most occurring number.

Given the sequence of numbers in order of size as 5, _, _, _, _ 24

Since 2 number falls in the middle and the median is 14, hence:

x +y/2 = 14

Since 8 is the mode, we can assume x = 8 in order to determine "y" as shown

8+y/2 = 14
8+y = 28
y = 16

The sequence of numbers will become 5, 8, 8, 16, _ 24 (8 was repeated twice being the mode)

The last unknown number can then be any value between 16 and 24. Using 22 as the last unknown value, the remaining four cards that could be on the card are 8, 8, 16 and 22

Answer:

y = -x+10

Step-by-step explanation:

We have a point at ( 2,8) and a point at ( 4,6)

We can find the slope using

m = ( y2-y1)/(x2-x1)

   = ( 6-8)/ ( 4-2)

   = -2/2

  = -1

The slope is -1

We can see that it intercepts the y axis at 10 ( x=0 point)

Using the slope intercept form  y = mx+b  where m is the slope and b is the y intercept

y = -x+10

x- 10 = u

y2 = 20u

So, the focus for U  =  ( [tex]\frac{20}{4}[/tex]; 0)

The focus for x =  ( [tex]\frac{20}{4}[/tex]; 10, 0)
