can anyone help? i suck at math lol

Answer:

Step-by-step explanation:

Give three functions f(x), g(x), and h(x), you want various combinations of them.

If ✧ represents some generic math operator, we often use the notation ...

  (f ✧ g)(x)

as a shorthand way to write ...

  f(x) ✧ g(x)

The usual meaning of the operator applies.

The three given functions are ...

The definitions are substituted for the function name:

  (h -f)(x) = h(x) -f(x) = x² -(x -2)

  (h -f)(x) = x² -x +2

  (f +h)(x) = f(x) +h(x) = (x -2) +x²

  (f +h)(x) = x² +x -2

  (g -f)(x) = g(x) -f(x) = (2x +3) -(x -2) = 2x +3 -x +2

  (g -f)(x) = x +5

  (g +h)(x) = g(x) +h(x) = (2x +3) +x²

  (g +h)(x) = x² +2x +3

Answer:

15w+24

Step-by-step explanation:

Answer:

84 units

Step-by-step explanation:

Since, M is the midpoint of XY.

[tex] \therefore \: XM= MY \\ \\ 10w + 2 = 5w + 22 \\ \\ 10w - 5w = 22 - 2 \\ \\ 5w = 20 \\ \\ w = \frac{20}{5} \\ \\ w = 4 \\ \\ \because \: XY = 2XM \\ \\ \therefore \: XY = 2(10w + 2) \\ \\ \therefore \: XY = 2(10 \times 4+ 2) \\ \\ \therefore \: XY = 2(40+ 2) \\ \\ \therefore \: XY = 2 \times 42 \\ \\ \therefore \: XY =84 \: units[/tex]

Answer:

a = 100 + 45t

Step-by-step explanation:

$100 is a one time addition so it will be a constant

100

$15 is added three times a month, so $45 a month

t stands for months as shown in the question

100 + 15(3)t

Answer: y=2/3x+1

Step-by-step explanation:

y=2/3x-6

y=2/3x+b ==> Parallel to y=2/3x-6 since they both have the same slope

3=2/3 (3)+b

3=2*3/3 +b

3=6/3 +b

3=2+b

b=1

y=2/3x+1

Answer:

455

Step-by-step explanation:

This is a combinatorics problem.

It is asking  us the number of ways a sample of r elements can be obtained from a larger set of n objects where order does not matter and repetitions are not allowed

It is called n choose k and the formula is

[tex]C(n,r) = \binom{n}{r} = \frac{n!}{( r! (n - r)! )}[/tex]

Here the ! symbol represents the factorial of that number

For example,

[tex]n! = n\cdot(n-1)\cdot(n-2)......\cdot3\cdot2\cdot 1[/tex]

Here n = 15 and r = 12

How many ways can we arrange 12 people in 15 slots

[tex]C(n,r) = C(15,12)[/tex]

[tex]= \frac{15!}{( 12! (15 - 12)! )}[/tex]

[tex]= \frac{15!}{12! \times 3! }[/tex]

[tex]= 455[/tex]

You can use a calculator to do this but noting that

15! = 15 x 14 x 13 x 12! and 3! = 3 x 2 = 6 we get

[tex]= \frac{15!}{12! \times 3! } = \frac{15\cdot14\cdot13}{6} = 455[/tex]

Answer:

A) The correct inequality is: -18 < 53

B) The correct description is: Eduardo sent fewer text messages during May than April

Step-by-step explanation:

Month     Number of message

April        53

May         -18

A) The correct inequality is: -18 < 53

Reason:

We need to choose the correct inequality, negative number is less than positive number so the inequality will be -18 < 53

B) The correct description is: Eduardo sent fewer text messages during May than April

Reason:

Negative values shows that he has messaged under the allotted limit, while positive values shows the number of messages he was over the limit.

Answer: 6

Step-by-step explanation:

The length of the rectangle is 45 yd,

and the width of the rectangle is 9 yd.

Given that, The length of a rectangle is 5 times its width, and

the perimeter  is 108 yd.

Let the width of rectangle be 'x' yd ,

therefore the length of the rectangle is '5x' yd  as mentioned that the length is five times the width.

we know that,

Perimeter of the rectangle = 2(length + width)

and given perimeter of rectangle is 108 yd.

Therefore the perimeter = 2( 5x + x )

                               108    = 2( 6x )

                               108    = 12x

                          108/12    = x

                                x      = 9

we know that 'x' is nothing but the width of the given rectangle.

Therefore the width of given rectangle is 9 yd, and

The length of the given rectangle is 5x = 5 * 9 = 45 yd.

The correct statement is  BC equals to AC times CE all over CD.

We have, If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. this is known as the triangle proportionality theorem.

Given, DE and AB are parallel

So,   [tex]\frac{BC}{CE} =\frac{AC}{CD}[/tex]

[tex]BC = \frac{AC\times CE}{CD}[/tex]

Therefore in statement form we say that BC equals to AC times CE all over CD.

Answer:

x= 3/11

Step-by-step explanation:

Since you replace f(x) with 4,

4=-11x+7

-3=-11x

-3/-11=x

Answer:

51

Step-by-step explanation:

f(-4); f(x) = -11x + 7

f(x-4) = -11(-4) + 7

f(x-4) = 44 + 7

f(x-4) = 51

I basically just plugged -4 in for the value of the x's, and solved the equation.

The fourth-order accurate finite difference approximation is:

u00(x) = c−2u(x − 2h) + c−1u(x − h) + c0u(x) + c1u(x + h) + c2u(x + 2h) + O(h4).

Compute the coefficients using the matlab code fdstencil.m and check that they satisfy the system you determined in part (a).

Test this finite difference formula to approximate u

00(1) for u(x) = sin(2x) with values of h from the array hvals = log space(-1, -4, 13). Make a table of the error vs. h for several values of h and compare against the predicted error from the leading term of the expression printed by  fdstencils.

You should observe the predicted accuracy for larger values of h. For smaller values, numerical cancellation in computing the linear combination of u values impacts the accuracy observed.

Answer:

Step-by-step explanation:

The cost when no sugar is transported is 3250, so that is the "y-intercept". (There is no "y". The vertical axis is labeled "c", so that  is the c-intercept.)

The cost per ton is 125, so that is the slope or "rate of change". Each increase of 1 unit in the value of "s" will result in an increase of 125 in the value of "c". The grid lines for "c" are 500 apart, so 1 vertical grid space will correspond to 500/125 = 4 horizontal grid spaces.

The graph starts at the left side halfway between 3000 and 3500. It goes up 1 grid square for each 4 grid squares to the right.

Answer:

^two dimentional figure with algebra^

the perimwter from triangle is:

s1 + s2 + s3

ok, enter:

s1 + s2 + s3= 369

x + (8x -5) + 2x = 369

x + 8x - 5 + 2x = 369

group according to the same variable

(x + 8x + 2x) + (-5)=369

11x + (-5)=369

11x - 5= 369

11x = 369 + 5

11x =374

x =374 : 11

x = 34
