Answer: y = x + 5

Step-by-step explanation:

If x>5:

Then all of these values will be positive. So the absolute value symbols are unnecessary!

so we can re-write as:

y = x-3 + x+3 - x + 5

which simplifies to:

y = x + 5

The equation is rewritten without absolute value is y=3x-6.

The absolute value of a number is defined as its magnitude irrespective of the sign of the number. To find the absolute value of a real number, we consider only the number and remove the sign. It can only be a non-negative value.

The given equation is y=|x-3|+|x+2|-|x-5|.

Here, y=x-3+x+2-x-5

y=3x-6

Therefore, the equation is rewritten without absolute value is y=3x-6.

Step-by-step explanation:

your teacher wrote most of the solution in this picture.

all we need to do is simplify and transform the equation

28/4 = 21/N

7 = 21/N

7N = 21

N = 21/7 = 3

formally, the ratio of corresponding (side) lengths is the same for all corresponding sides or other lines (like heights) in similar shapes.

so, the rate 28/4 = 7/1 = 7 asked also to 21 and N.

28/7 = 4

and

21/7 = N = 3

Answer:

[tex]\huge\boxed{\boxed{N=3}}[/tex]

Step-by-step explanation:

Hello.

We have the proportion

[tex]\displaystyle\frac{28}{4} =\frac{21}{N}[/tex]

In order to solve a proportion, we should cross-multiply:

28×N=4×21

28N=84

Divide both sides by 28.

N=3

And we're done!

ur question is incompleteness

The value of the investment at the end of 3 years would be [tex]\£7,524.6[/tex].

Used the formula of the total amount that is,

[tex]A = P (1 + r)^n[/tex]

Where A = Total amount.

P = Principal amount

r = Interest rate (in decimal form)

n = Number of years

Given that,

Chloe invests £6500 for 3 years at 5% per annum compound interest.

Here the given values are,

P = £6500

n = 3 years

r = 5% = 0.05

Substitute all the values in the above formula,

The value of the investment at the end of 3 years is,

[tex]A = P (1 + r)^n[/tex]

[tex]A = \£6500 (1 + 0.05)^3[/tex]

[tex]A = \£6500 \times (1.05)^3[/tex]

[tex]A = \£6500 \times 1.05 \times 1.05 \times 1.05[/tex]

Therefore, the investment at the end of 3 years is,

Answer:

[tex]d = 29r + 10[/tex]

Solving steps:

To check :--

=> d = 29r + 10

according to the table lets insert 3 to check if it's correct

=> d = 29r + 10

=> d = 29(3) + 10

=> d = 87 + 10

=> d = 97

so therefore it gave us the correct answer according to the table the cost in dollar where 97 and since it gives us 97 it's correct

Step-by-step explanation:

x and y trade places.

y = 2x² - 4

y + 4 = 2x²

x² = (y + 4)/2

x = ±sqrt((y + 4)/2)

and for the usual notation we rename x to y and vice versa

y = ±sqrt((x + 4)/2)

and this is not a function, because there are now 2 result values for every input value.

Step-by-step explanation:

Step-by-step explanation:

Since the axis of symmetry is the x axis, we have a sideways parabola,

[tex] {y}^{2} = x[/tex]

Since the vertex is at the orgin, our answer will be

[tex]a(y - k) {}^{2} + h = 0[/tex]

[tex]a {y}^{2} = x[/tex]

It passes through (3,2).

[tex]a(2) {}^{2} = 3[/tex]

[tex]a(4) = 3[/tex]

[tex]a = \frac{3}{4} [/tex]

So our function is

[tex] \frac{3}{4} {y}^{2} = x[/tex]

Answer:

[tex]x=\dfrac34y^2[/tex]

Step-by-step explanation:

A graph with x-axis symmetry means that for every (x, y) point there is also a (x, -y) point on the graph, i.e. the x-axis acts like a mirror.  Therefore, it is a sideways parabola.

The general form of this type of equation is [tex]x=ay^2+by+c[/tex]

Since we know that the curve has a vertex of (0, 0) then [tex]c=0[/tex]

Therefore, [tex]x=ay^2+by[/tex]

Given that (3, 2) is on the curve, then (3, -2) is also on the curve.

Substituting the given point (3, 2):

[tex]3=a(2)^2+b(2)[/tex]

[tex]3=4a+2b[/tex]

Substituting the given point (3, -2)

[tex]3=a(-2)^2+b(-2)[/tex]

[tex]3=4a-2b[/tex]

Adding the equations together to eliminate [tex]b[/tex]:

[tex]\implies 6=8a[/tex]

[tex]\implies 3=4a[/tex]

[tex]\implies a=\dfrac34[/tex]

Therefore,

[tex]x=\dfrac34y^2+by[/tex]

Again, substituting point (3, 2) means that b = 0

Therefore, the final equation is:

[tex]x=\dfrac34y^2[/tex]

Step-by-step explanation:

x = cost of a small box

y = cost of a large box

16x + 14y =343

13x + 23y = 470.5

now we multiply both equations with factors so that we have the same number of x in both (we could the same for y, but I simply picked x, because their original factors are closer and smaller).

and then we subtract the second equation from the first and since the result for y.

13 × (16x + 14y = 343)

16 × (13x + 23y = 470.5)

gives us

208x + 182y = 4459

- 208x + 368y = 7528

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

0x - 186y = -3069

186y = 3069

y = $16.50

now let's pick e.g. the first original equation to get x :

16x + 14y = 343

16x + 14×16.5 = 343

16x + 231 = 343

16x = 112

x = $7.00

the cost of a small box is $7.00

the cost of a large box is $16.50

The fundamental counting principle is the primary rule for calculating the number of possible outcomes. If there are p possibilities for one event and q possibilities for a second event, then the number of possibilities for both events is p x q.
