If it’s only 1.4x + 3.5y then that’s the answer because you can’t do anything with them. Since one has an x variable and the other has a y variable you can’t combine them together.

Find the trig ratio. Reduce to<br> lowest terms.<br> 10<br> 24<br> sin A =

Luba_88 [7]

The value of sin A is equal to $\frac{5}{13}.$

<h3>RIGHT TRIANGLE</h3>

A triangle is classified as a right triangle when it presents one of your angles equal to 90º. In this triangle from the trigonometric ratios or the Pythagoras Theorem ( $hypotenuse^2=(side_1)^2+(side_2)^2$ ), it is possible finding angles or sides.

<h3>Trigonometric Ratios</h3>

The main trigonometric ratios for a right triangle are presented below.

$sin\alpha =\frac{opposite \; side}{hypotenuse}$

$cos\alpha =sin\alpha =\frac{adjacent\; side}{hypotenuse}$

$tan\alpha =\frac{opposite \; side}{adjacent\; side}$

The question asks the sin A. First, you should find the hypotenuse from Pythagoras Theorem.

$hypotenuse^2=(10)^2+(24)^2\\ \\ hypotenuse^2=100+576\\\\ hypotenuse^2=676\\ \\ hypotenuse=26$

Now you can find sin A.

$sin\A=\frac{10}{26}=\frac{5}{13}$

Which graph represents the solution set of -2y > 7x + 4?

Firdavs [7]

The equation of a line in point-slope form is expressed as:

y = mx + b

m is the slope of the line

b is the y-intercept

Given the inequality -2y > 7x + 4, this can also be expressed as:

-2y > 7x + 4

y < -7/2x -4/2

y< -7/2x - 2

This shows that the line will be a dashed line and cuts the y-axis at y= -2
