Evaluate 8 p + 3 q − 1 8 8p+3q−188, p, plus, 3, q, minus, 18 when p = 1 2 p= 2 1 p, equals, start fraction, 1, divided by, 2, end fraction and q = 7 q=7q, equals, 7.

Value of the expression will be 7

Explanation

Given value of the variables are : and

Given expression:

So, plugging the values of and into the above expression, we will get...

So, the value of the expression will be 7.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
