I think you meant the two <em>segments</em><em> </em>are identical, if so then:

3x + 16 = 5x - 22 \\  - 2x =  - 38 \\ x = 19

Answer:

x = 19

Step-by-step explanation:

3x + 16 = 5x - 22

3x - 5x = -16 - 22

-2x = -38

x = -38/-2

x = 19

Take the equation: y = 520 + 14x and put each value from the table in for x and y.  

100 = 520 + 14 * -30
100 = 520 + -420
100 = 100   When we get an answer like this where the numbers on both sides of the equation match, we know that this (x,y) point is a part of the solution to the function.

So, you would work through each line in the table.  If they are all like the one above, the answer is Yes.  If not, it is no.

nevsk [136]

Answer: $2800

Step-by-step explanation:

if the function is f(x) and shes already saved $1000 plug in the functions, or in other words plug in x for weeks.

1000 + 150 x

(plug in x)

1000 + 150 x 12

so now you do 150 x 12 which equels 1800

then add how muh shes saved and thats will be your total.

From a sample of 9,750 Ajax trucks, 273 developed transmission problems within the first two years of operation. What is the pro
-Dominant- [34]

Answer:

0.028

Step-by-step explanation:

Let sample space, S, be the trucks.

Hence, n(S)= number of trucks=9750

Let E be the event of the truck failing within the first two years of operation.

Hence, n(E)=273

Therefore by classical definition of probability, the probability of occurrence of the event E, denoted by P(E), is

P(E)=\frac{n(E)}{n(S)}=\frac{number of trucks failed within two years of operation}{Total number of trucks}

⇒P(E)=\frac{273}{9750}=0.028
