Answer:
Linear relationship
Step-by-step explanation:
This is a linear relationship as it is expressed in the form y= mx+b
Here y= n b = -6 and x= m
A linear equation corresponds to a straight line hence it shows a linear relationship.
There is a correspondence between algebra and geometry through co ordinate system. We can convert a point into a pair of numbers and vice versa.
If we are given the value of y we can determine x and vice versa.
n = 4m – 6
In the given equation suppose x = 5 so y will be 14
n= 4(5)- 6
n= 20-6= 14
Also if we have y= 18 x will be 6
n = 4m – 6
18 + 6= 4m
24/4= m
m= 6
Answer:
18 children weighed less than 50 pounds.
Step-by-step explanation:
Ok, adding into the explanation what the heck this kind of a table is. The "stem" column is the tens place of each of the children's weights. The "leaf" is the ones digit of each of the children's weights. So in the row where the stem is 2, there were 2 kids weighing 23 and 25 pounds.
For your question, we have to add up how many students have a weight with a "stem" less than 5, because that's where 50 pounds starts.
8 + 2 + 5 + 3 = 18 children weighed less than 50 pounds.
Answer: -57
Step-by-step explanation: -48 + (9 - 18) -48 + -9 = -57
domain is {2.4, 4.8, 6.3, 8.8, 10.1 }
For domain, equate f(x) to each value in the range and solve for x
7x - 2.7 = 14.1 ⇒ x = 
= 2.4
7x - 2.7 = 30.9 ⇒ x = 
= 4.8
7x - 2.7 = 41.4 ⇒ x = 
= 6.3
7x - 2.7 = 58.9 ⇒ x = 
= 8.8
7x - 2.7 = 68 ⇒ x = 
= 10.1
The rectangle is 7 x 4 so the area is 28 sq cm
The triangle has a base of 4 and a height of 3.
The formula is A = 1/2 * b*h
You have 2 triangles so:
2(1/2)*4*3= 12 sq cm
Add together:
28 + 12= 40 sq cm
