Answer:

1/9

Step-by-step explanation:

The ratio of areas is the square of the scale factor for linear dimensions.

Area(y)/Area(x) = (1/3)^2 = 1/9

-3/5m + 8 = 20<br> what is the answer of m

horrorfan [7]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

$\qquad \sf \dashrightarrow \: - \frac{ 3}{5} m + 8 = 20$

$\qquad \sf \dashrightarrow \: - \frac{ 3}{5} m = 20 - 8$

$\qquad \sf \dashrightarrow \: - \frac{ 3}{5} m =12$

$\qquad \sf \dashrightarrow \: - \frac{ }{} m =12 \times \frac{5}{3}$

$\qquad \sf \dashrightarrow \: - m = 4 \times 5$

$\qquad \sf \dashrightarrow \:m = - 20$

Write a linear function f with f(0)=7 and f(3)=1.

choli [55]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

a = ( 0 , 7 ) & b = ( 3 , 1 )

First need to find the slope using the following equation :

$slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\$

$slope = \frac{1 - 7}{3 - 0} \\$

$slope = \frac{ - 6}{3} \\$

$slope = - 2$

_________________________________

We have following equation to find the point-slope form of the linear functions using the slope and one of the through points .

$y - y(0) = m \times ( \: x - x(0) \: )$

$x(0) = x - coordinate \: \: of \: \: through \: \: point \\$

$y(0) = y - coordinate \: \: of \: \: through \: \: point \\$

$m = slope$

I choose point (( a )) to put in the equation.

$y - 7 = - 2 \times (x - 0)$

$y - 7 = - 2x + 0$

$y - 7 = - 2x$

Add sides 7

$y - 7 + 7 = - 2x + 7$

$y = - 2x + 7$

This the slope-intercept form .

Done...

Choose one of the factors of 6x^3 + 6

ivanzaharov [21]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$6x^3+6$

Now, by factorising , we get

$6x^3+6\\=6(x^3+1)$

Now, we use the formula i.e.

$a^3+b^3=(a+b)(a^2-ab+b^2)$

By using this, we get ,

$6(x^3+1)\\=6(x+1)(x^2-x+1)$

So,

$(x+1) \text{ is the factor of }6x^3+6.$
