The answer is 320.
If 16 = x / 20, then x = 320
Multiply both sides of the equation by 20:
20 * 16 = 20 * x / 20
Multiply the terms on the left side of the equation:
320 = 20x/20
320 = 20/20 * x
Simplify the rigth side of the equation:
320 = 1 * x
320 = x
Therefore, x = 320
C = pi*d; solve for d.
Divide both sides of this eqn by pi: C/pi = d (answer)
Answer:
(D) (a + 4)/2
Step-by-step explanation:
To solve, you need to subtract the first equation from the second.
9p = 3a + 1
<u>- 7p = 2a - 3</u>
2p = 1a + 4
Now, you need to rearrange the equation so that is equal to p.
2p = a + 4
(2p)/2 = (a + 4)/2
p = (a + 4)/2
This gives you answer choice D.
"Interpret the rate of change and the y-intercept.
"
Rate of change is 5. Each ticket costs 5$.
Y-intercept is (0,-17). They spent $17 on supplies before they sold tickets.
(Sorry, you probably already know the answer)
Answer:
P' (- 7, - 5 )
Step-by-step explanation:
A translation of 3 units to the left means subtractin 3 from the x- coordinate with no change to the y- coordinate, thus
P(- 3, 5 ) → (- 3 - 4, 5 ) → (- 7, 5 )
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(- 7, 5 ) → P'(- 7, - 5 )
