Answer:
12
Step-by-step explanation:
Using the pythagorean theorem, we know that a^2+ b^2=c^2
In our case, we know b, which is 5 and c which is 13.
If we plug that into the equation, we get a^2+ 5^2 = 13^2
Next, we simplify the equation. a^2 + 25 = 169
Then we subtract 25 from 169. 169 - 25 = 144.
Lastly, we do the square root of 144 and we get 12 which is the missing side.
Answer:
Rewrite so y is on the left side of the inequality.
−83y>43
Multiply each term by −38 and simplify.
Inequality Form:
y<−1/2
Interval Notation:
(−∞,−1/2)
Step-by-step explanation:
Answer:
2x + 3y + 5z = 9
Step-by-step explanation:
The normal defines all the planes perpendicular to that vector. To isolate to a single plane, just apply the known point.
ax + by + cz = d
2x + 3y + 5z = d
2(1) + 3(-1) + 5(2) = 9

draw a rectangle with these dimensions on the grid
The cost of one adult ticket is $8 and cost of one child ticket is $8.
Step-by-step explanation:
Let,
Cost of one adult ticket = x
Cost of one child ticket = y
According to given statement;
3x+y=32 Eqn 1
7x+2y=72 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 3 from Eqn 2
Putting x=8 in Eqn 1
The cost of one adult ticket is $8 and cost of one child ticket is $8.
