Answer:
-5
Step-by-step explanation:
Subtracting a negative is just like adding a positive. A way to think about this is that the negative cancel each other out are you left with a positive number.
You can rewrite this as -87 + 82.
Then, you solve and get -5.
The first step is to ignore the inequality symbol first and replace it with '=' sign. Then, find the x- and y-intercepts.
15x + 10y = 1,100
x-intercept:
15x + 0 = 1,100
x = 1,100/15 = 73.33
y-intercept:
0 + 10y = 1,100
y = 1,100/10 = 110
Now, plot points (73.33,0) and (0,110). Since the equality symbol is ≥, which has an equal sign to it, connect the points using a solid line.
Next, let's find a point on the graph. Suppose it is the origin at (0,0). Use this points to the equation.
15x + 10y ≥ 1,100
15(0) + 10(0) ? 1,100
0 ? 1,100
0 < 1,100
It makes the symbol ≥ false. Therefore, it means that the other region bounded by the line is the solution. So, you shade this area. The final graph is shown in the picture attached.
Answer:
70
Step-by-step explanation:
Area of a kite, is to multiply the two diagonals and divide by 2:
p(diagonal) * q(diagonal) / 2
pq / 2.
P = 14
Q = 10.
(14 * 10) / 2
140/2
70
