Answer:

The answer is 88

Step-by-step explanation:

since x=8

x^2= 64

3x=3×8

=24

x^2+3x= 64+24

=88

9/10 and -9/10 determine if parallel, perpendicular, or neither
irakobra [83]
Parallel means the slopes are the same
Perpendicular means they have opposite reciprocal slopes.

We can apply these concepts to this question. Although they are opposites of each other, they are not reciprocals.

So, the answer is neither

Hope this helps!

Find the values of x and y given that ABCD is congruent to EFGH.
Kazeer [188]

Answer:

x=7 , y = 8.

Step-by-step explanation:

10x+65 = 135

or, 10x = 70

so, x = 7

Now,

4y-4=28

or, 4y = 32

so, y = 8

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).
