Answer:
The solutions to the system of equations are:
Step-by-step explanation:
Given the system of the equations
Isolate x for for 4x-3y=-13
Divide both sides by 4
substitute y=5
The solutions to the system of equations are:
To reflect in the line y = -x + 6, we translate everything down 6 first. This will make it seem like we are reflecting in the line y = -x
(x,y) → (x, y-6)
Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative
(x,y) → (-(y-6), -x)
Then we move everything back up again
(x,y) → (-(y-6), -x + 6)
I will present to you an example. Reflect the point (-4, 8) in the line y = -x + 6.
(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)
You should graph this out to confirm with the reflection line.
Px - 45 = QX + 75
Px - Qx = 75 + 45 = 120
A. If P = - 45 and Q = - 75, then
- 45x + 75 x = 120
30x = 120 and x = 40
B. If P = 45 and Q = - 15, then
45x - 15x = 120
30x = 120
x = 40
D. If P = 15 and Q = 75, then
15x - 75x = 120
- 60x = 120
x = - 2
C. If P = 15 and Q = 15, then
15x - 15x = 120
0 = 120 which is absurd.
Hence, P = 15 and Q = 15 result in an equation with no solution.
<em>$650</em>
- Step-by-step explanation:
<em>90% .............. $585</em>
<em>100% ............ $ x</em>
<em>x = 100×585/90</em>
<em>= 58500/90</em>
<em>= $650</em>
