Answer:

B. Not proportional

10/14 and 30/36 don't have a proportional relationship, since the simplest form of these both ratios are 5/7 and 5/6, which aren't equivalent.

$\left( 16 x^8 y^{-12} \right)^{\frac 1 2} = 16^{\frac 1 2} (x^8)^{\frac 1 2} (y^{-12})^{\frac 1 2} = 4 x^4 y^{-6} = \dfrac{4 x^4}{y^6}$

Find x.<br> a. 30.9<br> b. 34.4<br> c. 17.1<br> d. 15.4

Naya [18.7K]

Answer:

x = 17.1

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj / hyp

cos 42 = x/23

23 cos 42 = x

17.09233 =x

Rounding to 1 decimal place

x =17.1

A line that passes through the point (1, –1) and parallel to another line whose slope is 1.

Mars2501 [29]

Parallel lines have same slope so so far the new equation looks like this
$y = 1x + b \\ y = mx + b$
now you plug in you points or coordinates to find b or solve for the y-intercept
$- 1 = 1(1) + b$
$- 1 = 1 + b$
$- 1 = 1 + b \\ - 1 = - 1$
$- 2 = b$
now that you have your b your final solution is
$y = 1x - 2 \: or \: y = x - 2$
