-4r + 8 = 8 - 4r
0 = 0 so it's like {}
Answer:
r = 0
Step-by-step explanation:
This is actually the first time I've actually had a equation with the variable equaling 0.
so first things first you have the equation:
r + 8 - 5r = 2(4 - 2r)
so you are going to add or multiply all the variable numbers together and the none variable numbers together like so:
r + (-5r) and (2*4) and (2* (-2r)) to get the equation looking like so:
8+ (-4r)= 8 -4r
you then add -4r to both sides to get this equation:
8+ ( -4r)= 8 -4r
+ 4r +4r
8 = 8 + r
you then subtract 8 from both sides to get r:
8 = 8 + r
-8 -8
0 = r
to check substitute the 0 into r in the equation:
r + 8 - 5r = 2(4 - 2r)
0 + 8 - (5*0) = 2(4- (2*0))
8 = 8

Split 18 into the ratio 1:2
Answer:
6 : 12
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 = 3 parts
Divide by 3 to find the value of one part of the ratio
18 ÷ 3 = 6 ← value of 1 part of the ratio, thus
2 parts = 2 × 6 = 12
1 : 2 = 6 : 12
The number 18 splitted into a ratio of 1 : 2 is 12 and 6.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Slitting in the ratio 1 : 2 can be done in this manner,
{1/(1+2)]×18.
= (1/3)×18.
= 6.
And,
{2/(1+2)]×18.
(2/3)×18.
= 12.

Triangle PQR with coordinates P(3,-4), (6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically. What will
be the coordinates of P'Q'R'?
Answer:
(0, 2), (3, 5) and (3, 0)
Step-by-step explanation:
Since, Points P(3,-4), Q(6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically.
Therefore,
P' (3 - 3, - 4 +6) = P' (0, 2)
Q'(6 - 3, - 1 + 6) = Q'(3, 5)
R'(6 - 3, -6 + 6) = R'(3, 0)
Thus, the coordinates of P'Q'R are (0, 2), (3, 5) and (3, 0).
Answer:
P'(0, 2), Q'(3, 5), R'(3, 0)Step-by-step explanation:
Given
Points P(3,-4), Q(6, -1), R(6, -6) Translation: x -3, y + 6New points:

Answer:
The answer is
[tex] \huge \frac{2}{3} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
From the question we have
[tex]m = \frac{10 - 6}{4 - - 2} = \frac{4}{4 + 2} = \frac{4}{6} = \frac{2}{3} \\ [/tex]
We have the final answer as

Answer:
x^2+y^2-32x+24y+375=0
Step-by-step explanation:
Equation of circle with given centre (h,k) and radius=r is
(x-h)^2+(y-k)^2=r^2
Given centre are=(16, - 12) and radius= 5
So equation of circle=
(x-16)^2+(y- -12)^2=5^2
x^2-32x+256+y^2+24y+144=25
x^2+y^2-32x+24y+375=0
