A police department believes that the number of serious crimes which occur each month can be estimated by the equation c=1200-12

e-lub [12.9K]

Answer:

a) -12.5; the crimes committed goes down by 12.5 every time there are more police officers assigned to patrol.

b) 1200. The number of crimes committed if no police officers were on patrol.

c) 96. The hypothetical number of police officers on duty if no crime were to ever occur.

Step-by-step explanation:

The intercepts are found by substituting 0 for the other variable in the equation.

For example, if you wanted to find the C intercept, all you have to do is make P = 0, so you would end up with C = 1200 - (12.5 * 0), which simplifies down to 1200.

You would apply the same strategy to find the P intercept.

Find the X intercept and the Y intercept of the graph of the equation. 9/8x+8y=18

aleksandr82 [10.1K]

Answer:

$\large\boxed{x-intercept=16\to(16,\ 0)}\\\boxed{y-intercept=\dfrac{9}{4}\to\left(0,\ \dfrac{9}{4}\right)}$

Step-by-step explanation:

$\dfrac{9}{8}x+8y=18\\\\x-intercept\ \text{is for}\ y=0:\\\\\dfrac{9}{8}x+8(0)=18\\\\\dfrac{9}{8}x+0=18\\\\\dfrac{9}{8}x=18\qquad\text{multiply both sides by}\ \dfrac{8}{9}\\\\\dfrac{8\!\!\!\!\diagup^1}{9\!\!\!\!\diagup_1}\cdot\dfrac{9\!\!\!\!\diagup^1}{8\!\!\!\!\diagup_1}x=\dfrac{8}{9\!\!\!\!\diagup_1}\cdot18\!\!\!\!\!\diagup^2\\\\x=16\\\\y-intercept\ \text{is for}\ x=0:\\\\\dfrac{9}{8}(0)+8y=18\\\\0+8y=18\\\\8y=18\qquad\text{divide both sides by 8}\\\\y=\dfrac{18}{8}\\\\y=\dfrac{9}{4}$
