Answer:
x = -15
Step-by-step explanation:
It appears the drawing is showing two representations for the distance LK. Of course, they both have the same value.
10 = LK = x+25
Subtracting 25 from the equation, we have ...
-15 = x
(This value of x makes KJ = (2(-15)+27) = -3, a nonsense value.)
_____
Alternate (more sensible) interpretation
If the bottom line is intended to represent LJ, then we have ...
10 +(2x+27) = (x +25) . . . . LK +KJ = LJ
x +37 = 25 . . . . subtract x
x = -12 . . . . . . . subtract 37
With this value of x, the length of KJ is 2(-12)+27 = 3, and the overall length LJ is (-12)+25 = 13. This is consistent: LK=10, KJ = 3, LJ = 13.
Answer:
The length of P'Q' is 4 units
The length of P'R' is 3 units
Step-by-step explanation:
If you rotate the figure 180° then the vertex would be R, and from P to Q is 3 units left and 4 units down
To find the length of side P'Q' after rotating triangle PQR 180° about the origin, we need to find the distance between the points P'(0,0) and Q'. When you rotate a point (x, y) 180° about the origin, the new coordinates are (-x, -y). Using the distance formula, we can find the length of side P'Q': d = sqrt((-3-0)^2 + (-4-0)^2) = sqrt(9 + 16) = sqrt(25) = 5. Therefore, the length of side P'Q' is 5 units.
To find the length of side P'Q' after rotating triangle PQR 180° about the origin, we need to find the distance between the points P'(0,0) and Q'.
When you rotate a point (x, y) 180° about the origin, the new coordinates are (-x, -y).
So, the coordinates of point Q' would be (3, 4) rotated 180°, which is (-3, -4).
Using the distance formula, we can find the length of side P'Q':
d = sqrt((-3-0)^2 + (-4-0)^2) = sqrt(9 + 16) = sqrt(25) = 5.
Therefore, the length of side P'Q' is 5 units.

The domain of this function is ?
negative infinity to zero
0 to infinity
negative infinity to infinity
The range of this function is?
0 to infinity
3 to infinity
negative infinity to infinity
The domain of this function is:
C.) Negative infinity to infinity
The range of this function is:
A.) 0 to infinity
Y=4^x-5+3
The domain of this function is:
C.) Negative infinity to infinity
The range of this function is:
B.) 3 to infinity
For the function y = 3 • 5x, the domain is all real numbers (negative infinity to infinity) and the range is all real numbers from zero to infinity.
In mathematics, the domain of a function is the complete set of possible values of the independent variable. In the case of the function y = 3 • 5x, the independent variable is 'x' which can take any real number. Therefore, the domain of this function is from negative infinity to infinity.
The range of a function is the complete set of possible values of the dependent variable. In this function, the dependent variable is 'y', which increases as 'x' increases. Because the lowest value y can take is 0 (when x is 0), the range is from 0 to infinity.
