SOLVE THIS: 6(2x+3) =42

Mathematics
1 answer:
AlladinOne [14]3 years ago
7 0

Answer:

x = 2

Step-by-step explanation:

First, distribute 6 to all terms within the parenthesis.

6(2x + 3) = 12x + 18

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

12x + 18 = 42

First, subtract 18 from both sides.

12x + 18 (-18) = 42 (-18)

12x = 24

Isolate the variable x. Divide 12 from both sides.

(12x)/12 = (24)/12

x = 24/12

x = 2

2 is your answer for x.

A circle is centered at the point (-7, -1) and passes through the point (8, 7). The radius of the circle is units. The point (-1
padilas [110]

 

hello :<span>
<span>an equation of the circle Center at the A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -7  and b = -1 (Center at: A(-7,-1) )
r = AP.... P(8,7)
r² = (AP)²
r² = (8+7)² +(7+1)² =225+64=289 ...... so : r = 17
an equation of the circle that satisfies the stated conditions.
Center at  </span></span>A(-7,-1), passing through P(8, 7) is :  

(x+7)² +(y+1)² = 289

The point (-15,y ) <span>lies on this circle : (-15+7)² +(y+1)² = 289....(subsct : x= -15)
(y+1)² = 225
(y+1)² = 15²
y+1 = 15   or y+1 = -15
y = 14  or y = -16
you have two  points : (-15,14)  , (-15, -16)</span>
