Answer:

the answer is // x^2 - x +1 (apex)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the number = x

So we are trying to work out what number must be subtract from the numerator and denominator of 5/3 to equal 5/7.

You can write this as:

[tex]\frac{ 5-x}{3 - x} = \frac{5}{7}[/tex]

Then you want to get rid of the fractions so multiply both sides by 3-x

[tex]5 - x =[/tex] [tex]\frac{5 ( 3 - x)}{7}[/tex]

Then multiply both sides by 7

[tex]7( 5 - x) = 5 ( 3 - x)[/tex]

Multiply it out.

35 - 7x = 15 - 5x

Add 7x to both sides:

35 = 15 - 5x + 7x

35 = 15 + 2x

Subtract 15 from both sides

35 - 15 = 2x

20 = 2x

To find x, divide both sides by 2.

x = 10.

Answer:

a= 7w-28b

Step-by-step explanation:

w= 7a +4b

           -4b

w-4b =7a

w/7 - 4b/7 =7a/7

a= w/7 -4b/7

a= 7w-28b

Responder:

$ 2560

Explicación paso a paso:

Dado lo siguiente:

Importe total (A) = 60000

Pago inicial = 20% de A

Pago inicial = 0,2 * 60000 = 12000

Importe pendiente de pago = (60000 - 12000) = 48000

Calcular el interés simple sobre el saldo de 48000 = principal

principal * tasa * tiempo

(48 000 * 0,12 * (30/6))

48000 * 0,12 * 5 = 28800

Por tanto, el importe total a pagar durante 30 meses será:

(48 000 + 28800) = 76800

Dado que el pago mensual es fijo:

Pago mensual = (monto total a pagar / cantidad de meses)

Pago mensual = (76800/30)

Pago mensual = $ 2560

Answer: (0,-6)

Step-by-step explanation:

To find the y-intercept, we can rewrite the equation into slope-intercept form.

3x+5y=-30            [subtract both sides by 3x]

5y=-3x-30             [divide both sides by 5]

y=-3/5x-6

Now that the equation is in slope-interceot form, we know that the y-intercept is -6, we know that the answer is (0,-6).

= 24 - 16 + 4 - 576

= 24 + 4 - 16 - 576

= 28 - 592

= -564

2. 2 3/4 + 8 3/4

Mínimo común múltiplo de los denominadores = 4

= (2 + 8) + (3 + 3/4)

= 10 + (6/4)

= 10 + 1 2/4

= 10 +1 1/2

= 11 1/2

Answer:

the answer is false. you first multiply the number by the numerator then add it to the denominator

Supplementary angles are angles that sum up to 180 degrees

Step 1:

If m<x and m<y are supplementary, hence;

m<x + m<y = 180 ....................1

Step 2:

If m<y is a supplement to m<z, hence:

m<y + m<z = 180 ...........................2

Equating 1 and 2

m<x + m<y  = m<y + m<z

Subtract m<y from both sides

m<x + m<y-m<y  = m<y + m<z - m<y

m<x = m<z

This proves the statement m<x = m<z

Answer:

6hours

Step-by-step explanation:

From the given information:

Suppose it took Karl x hours to retile her bathroom,

Then it will take Della 3 hours longer i.e (3+x) hours

If Della and Karl work together or will take them 2 hours

The objective is to determine how long it will take Delia to retile the bathroom alone?

∴

[tex]\dfrac{1}{x}+\dfrac{1}{3+x}= \dfrac{1}{2}[/tex]

[tex]\dfrac{x+3+x}{x(3+x)}= \dfrac{1}{2}[/tex]

[tex]\dfrac{2x+3}{3x+x^2}= \dfrac{1}{2}[/tex]

By cross multiplying, we have:

2(2x+3) = 3x+x²

4x + 6 = 3x + x²

3x + x² - 4x - 6

x² - x - 6 = 0

Using quadratic equation

x² -3x +2x - 6 = 0

x(x - 3) + 2(x - 3) = 0

(x +2) (x - 3) = 0

x + 2 = 0 or x - 3 = 0

x = -2 or x = 3

Since we are concerned about the positive integer,

Then, Karl = x = 3 hours while Della which is (3+x) = 3+3 = 6hours

The values of the function are,

f (- 3) = 16,000 meaning a qualifying applicant with - 3 siblings in their household would get $16,000 in financial aid. This interpretation does not make sense in the context of the problem.

f (3) = 34,000 meaning a qualifying applicant with 3 siblings in their household would get $34,000 in financial aid. This interpretation makes sense in the context of the problem.

The domain for this function is x ≥ 0, indicating that the number of siblings must be a non-negative whole number or zero.

Given that,

The function is,

[tex]f (x) = 25000 + 3000x[/tex]

Where x is the number of siblings.

Hence, the values of the function are found as,

[tex]f (x) = 25000 + 3000x[/tex]

Put x = - 3;

[tex]f (- 3) = 25000 + 3000 \times - 3[/tex]

[tex]f (- 3) = 25000 - 9000[/tex]

[tex]f (- 3) = 16,000[/tex]

Put x = 3;

[tex]f (x) = 25000 + 3000x[/tex]

[tex]f (3) = 25000 + 3000 \times 3[/tex]

[tex]f ( 3) = 25000 + 9000[/tex]

[tex]f (3) = 34,000[/tex]

Since the given function is,'

[tex]f (x) = 25000 + 3000x[/tex]

Regarding the domain of the function,

Since the number of siblings (x) must be a non-negative integer, it represents the count of individuals.

Therefore, the appropriate domain for this function would be x ≥ 0, meaning x can be any non-negative whole number or zero.

Answer:

1/4

Step-by-step explanation:

Negative exponents basically flip the number upside down,

so 4 ^ -2 would be 1/4^2

where the four has a power of 2.

The answer would therefore be 1/16

Numbers to the power of 1, is just the same number, so if you have negative exponents, it would be the same 4, except flipped over.

Answer:

The largest African elephant weighed 13.5 tons (27,000 pounds) The world record holder weighed this much and stood 13ft/4m tall at the shoulder. There are other species of elephants, namely the Asian and the Indian, but they are much smaller than the African. The African elephant is the king among the giants on land. No other land animal comes close to the size of these creatures. It would take 165 full-grown men to make up the same weight as the world's record African elephant. The noise of an elephant digesting its food (when its tummy's growling) can be heard up to 600ft/183m away. Elephants actually have control over their digestive processes because they are able to stop the sounds of digestion when they sense danger. Here are some other cool elephant factoids:

Answer:

1449616

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step 1 : Find the slope/gradient (this is known as "m")

The slope formula is :

[tex]m = \frac{y2 - y1}{x2-x1}[/tex]

*Note that we are given 2 points:

For the first point (-2,-1) , this means x1 = -2 and y1 = -1

For the second point (2,4), this means x2 = 2 and y2 = 4

If we substitute those values into the slope formula you end up with this:

[tex]m = \frac{y2-y2}{x2-x1} = \frac{4 - (-1)}{2 - (-2)} = \frac{4+1}{2+2} =\frac{5}{4}[/tex]

Step 2: Substitute the values into the point-slope formula:

[tex]y - y1 = m(x- x1)[/tex]

Now that we know m = 5/4 , you can substitute this into the above formula and you get:

[tex]y - y1 = m(x- x1)[/tex]

[tex]y - (-1) = \frac{5}{4} (x - (-2)) \\y + 1 = \frac{5}{4} ( x + 2)[/tex]

[tex]y = \frac{5}{4}(x + 2) - 1[/tex]

[tex]15x - 10 = 10 + 6 + 2x[/tex]

[tex]15x - 10 = 16 + 2x[/tex]

Plus sides 10

[tex]15x - 10 + 10 = 2x + 16 + 10 \\ [/tex]

[tex]15x = 2x + 26[/tex]

Subtract sides -2x

[tex]15x - 2x = 2x - 2x + 26[/tex]

[tex]13x = 26[/tex]

Divided sides by 13

[tex] \frac{13}{13}x = \frac{26}{13} \\ [/tex]

[tex]x = 2[/tex]

This question makes no sense... It says 12 are in mint condition, then says only 6 are? I'd just say 18? I have no clue what equation to go with though. Sorry.

Step-by-step explanation:

Answer:

"A" is correct.

Answer:

The value of m to be substituted in y – y1 = m(x – x1) is the negative reciprocal of the slope of the given line.

Substitute this in for m.

Substitute the given point, (x1, y1), in the point-slope form.

Isolate y by multiplying out m and subtracting y1 to rewrite the equation in slope-intercept form: y = mx + b.

It should be something like this, hope this helped you!
