help me find the rate of change
Answers
Answer:
3
Step-by-step explanation:
To find the rate of change, we want to use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values using two given points. I will use the first and last points.
(1, -2) & (13, 34)
(34 - (-2)) / (13 - 1)
Simplify the parentheses.
= (34 + 2) / (12)
= 36/12
Simplify the fraction.
36/12
= 3
This is your slope.

Answers
The time the bus should arrive at School Road from Hope Street is 08 : 04.
The time of the latest bus that Jo can catch from the Bus Station is 07 00.
The time the bus takes to travel from the bus station to School Road is 14 minutes.
How to find the time ?The table shows that when a bus leaves for School Road from Hope Street, at 07 54, it will arrive on School Road at 08 04.
The time it takes from the bus station to School road is:
= Arrival time at school road - Departure time from Bus station
= 08 04 - 07 50
= 14 minutes
If Jo wants to be in school road at 8 am by the latest, she needs to leave before :
= 8 am - 14 minutes
= 07 46
The only bus leaving before this time is the 0700 bus from the Bus Station.

What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Fixed amount he earns per week = $15
Additional amount added depending on the number of subscription sold = $3
Let x be the number of subscription sold.
Amount earned in a week = 15 + 3x
If amount earned is $90,
15 + 3x = 90
3x = 75
x = 75 / 3 = 25
Hence the number of subscriptions is 25.

Answers
Answer:

Step-by-step explanation:
−3y < −14
dividing both side by -3
-3y/-3 <-14/-3
y<14/3
The solution of the inequality will be equal to y<14/3.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given inequality will be solved as,
−3y < −14
Dividing both sides by -3 and solving further.
-3y/-3 <-14/-3

Can the measurement from △DEF be determined using only the Law of Cosines? State whether each measurement can be determined using only the Law of Cosines by answering “yes” or “no”.
m∠D =
m∠E =

Answers
9514 1404 393
Answer:
∠D - no∠E - noDE - yesStep-by-step explanation:
With a single application of the Law of Cosines, you can only find one of an unknown side or an unknown angle. The other three elements in the 4-variable equation must be specified.
However, a single application of the LoC can be used to find DE. Then, knowing the three sides, either of the unknown angles can be found from an additional application of the LoC.
So, the answer is "it depends." It is yes to all if finding DE first is allowed. It is "no" to the angles if they must be found without finding DE first.

Step-by-step explanation:
ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j
. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127
