Hi there! The answer is j = - 42.
In order to find the value of j, we need to set up and solve an equation.
The sum of j and 47 can be rewritten as
j + 47
The sum described above equals 5, so now we have all the information we know to set up the equation.
j + 47 = 5
Subtract 47 from both sides.
j + 47 - 47 = 5 - 47
j = - 42.
The answer is j = - 42.
~ Hope this helps you!
Answer:
first group x's with x's and y's with y's
then complete the squra with x's and y's
2x^2-8x+2y^2+10y+2=0
2(x^2-4x)+2(y^2+5y)+2=0
take 1/2 of linear coeficient and square
-4/2=-2, (-2)^2=4
5/2=2.5, 2.5^2=6.25
add that and negative inside
2(x^2-4x+4-4)+2(y^2+5y+6.25-6.25)+2=0
factor perfect squares
2((x-2)^2-4)+2((y+2.5)^2-6.25)+2=0
distribute
2(x-2)^2-8+2(y+2.5)^2-12.5+2=0
2(x-2)^2+2(y+2.5)^2-18.5=0
add 18.5 both sides
2(x-2)^2+2(y+2.5)^2=18.5
divide both sides by 2
(x-2)^2+(y+2.5)^2=9.25
that is a circle center (2,-2.5) with radius √9.25

16x 2.5x 5= 200 that’s the volume I think it’s saying there is 19.3 grams for every centimeter of volume soo 200x 19.3 =3,860 mass ..... I would double check me
Answer:
smaller
Step-by-step explanation:
if a shape is being dilated to a scale factor lower than 1, it'll be smaller than the original figure
