<span>Given: 4y =2x-10, and y=6 Substituting for y in the equation gives 4(6) = 2x-10 or 24 = 2x-10 Adding 10 to both sides of the equation 24+10 = 2x - 10+10 34 = 2x Dividing both sides by 2 34/2 = 2x/2 Answer 17 = x</span>

How would you graph the solution set of x - 6 &lt; -3?
mezya [45]

Answer:

Draw an open circle on 3 and shade to the left.

Step-by-step explanation:

Given:

The inequality given is:

x-6

In order to solve for 'x', we add 6 on both sides of the inequality. This gives,

x-6+6

Therefore, the solution is 'x' less than 3.

So, 'x' includes all the values that are less than 3 and excluding 3 as the inequality sign is less than.

So, on a number line, the values that are less than 3 are to the left of 3. So, we shade to the left. Also, 3 is excluded from the solution. So, we use an open circle as shown below.

So, the first option is the correct option.

Which statensent is true about the coordinates of points A and 8?
Aleks04 [339]

\frac{y}{x} of point B is equal to  \frac{y}{x} of point A. Correct option A).

<u>Step-by-step explanation:</u>

Here we have  , a straight line in the graph between x-axis & y-axis . There are two points given here, A and B which lie in same line . Equation of line :

y = \frac{3}{4}x , passing through origin  . General equation of a line is :

y = mx+c , where m = slope of line  , c = x intercept , comparing this equation to to equation of line given in graph we get that m = 3/4 & c =0.

Useful info from here is slope = 3/4 . We know that slope = tan(theta) i.e.

⇒ slope = tanx\\

⇒ tanx = \frac{Perpendicular}{base}

⇒ tanx = \frac{y}{x}

⇒ slope = \frac{y}{x}

⇒ \frac{y}{x} =\frac{3}{4} , which is constant i.e. ratio of y over x is a constant  .Hence , \frac{y}{x} of point B is equal to  \frac{y}{x} of point A. Correct option A).

What<br> Fraction of<br> an hour is<br> 38 minuets
Vladimir79 [104]

Hello!

\large\boxed{\frac{19}{30}}

There are 60 minutes in an hour, so:

38 / 60

Reduce the fraction by diving by the GCF, or 2:

(38/2) / (60/2) = 19 / 30.
