Answer:
C. 42.
Step-by-step explanation:
This is an arithmetic sequence with common difference d = 4 and first term a = -3.
Sum of n terms = (n/2)[2a + (n - 1)d]
Sum of six terms = (6/2)[2(-3) + (6 - 1)4]
= 3 * (-6 + 20)
= 42.
Answer:
Rate
Step-by-step explanation:
Rate is basically also a ratio. but it is the comparing of two different quantities with different units.
As ratio is comparing of same or identical quantities thus it has no units. But on the other hand as rate is the comparison of different quantities, thus it has units.
for example:
When i compare two quantities, 1st is a distance quantity and 2nd is a time quantity i.e.
20 meters : 15 seconds
thus the lowest form of this relationship will be:
4 meters : 3 seconds
when i write it in Decimal form it becomes :
Ans : 1.33 meters/second (Distance per unit time)
As this ratio have remaining units thus it is referred to as "RATE".
Answer:
1. (2+2)/(-3+4)= 4/1= 4
y + 2 = 4(x + 4)
y + 2 = 4x + 16
y = 4x + 14 y-intercept:(0,14)
2. (0+5)/(-1+2)= 5/1= 5
y + 5 = 5(x + 1)
y + 5 = 5x + 5
y = 5x
y-intercept (0,0)
3. (-1+1)/(-5-3)= 0/-8= 0
y + 1 = 0(x - 3)
y + 1 = 0
y= -1
Answer:
Anthony is incorrect
According to the order of operations(PEMDAS), you must first multiply 10 × 3
which equals 30, then you add 2, which equals 32, finally you subtract 2, which brings you back to 30
10 × 3 = 30
2 + 30 - 2 = 30
