Answer:
57.1
Step-by-step explanation:
Perimeter Formula: P = 2l + 2w
Simply plug in what we know and solve:
269.4 = 2l + 2(77.6)
269.4 = 2l + 155.2
114.2 = 2l
l = 57.1
Step 1: Add 65 to all sides
Step 2: Add 4x to all sides
Step 3: subtract 70 to all sides
Step 4: divide by 4 to all sides
Ending: x is greater than or equal to -17.5
You will end up with it saying -17.5 is greater than or equal to -2.75 but since -17.5 is not greater than -2.75 the answer to this problem is ...
No solution because the inequality that you end up with won't make sense and therefore does not work in the problem
Answer: NO SOLUTION (yayayyayay).
Answer:
The new points to the triangle will be:
Step-by-step explanation:
Because the reflection point is at 
, all x values will subtract their distances from to get their new values. The y values remain the same.
The starting values are:
Point 
is 5 units away from , so we'll subtract 5 from -1 to get the new x value: 
, so 
.
Point 
is also 5 unit away from , so we'll subtract 5 from -1 to get the new x value: , so 
.
Point 
is 7 units away from , so we'll subtract 7 from -1 to get the new x value: 
, so 
.
Answer:
y + 1 = -14(x - 2)^2y = -14(x - 2)^2 - 1

Answer:
A computer costs $225 and a printer $150.
Step-by-step explanation:
Let c be the cost of a computer and p the cost of a printer, then:
3c + p = 825
4c + 2p = 1200
Multiply the first equation by -2:
-6c - 2p = -1650
Add this to the second equation:
-2c = -450
c = 225.
Now substitute c = 225 in the first equation:
3*225 + p = 825
p = 825 - 675 = 150.
