Answer:
Step-by-step explanation:
slope-intercept form is y=mx+b
m = slope = change in y/change in x
change in y/change in x = 2/1
m = 2
b = y intercept = y value when x = 0
using the slope, go left 2 units and down 4
when x = 0, y = 0
b = 0
y = mx+b when m = 2 and b = 0
y = 2x+0
y = 2x
Answer:
The sum of first eighteen terms of the arithmetic sequence is 
Option B is correct option.
Step-by-step explanation:
We need to find the sum of the first eighteen terms of the arithmetic sequence whose nth term is an = 15 + 8n
The formula used to calculate sum of arithmetic sequence is: 
Finding a₁ by putting n=1
We have 
Finding 18th term n=18
So, the sum of first eighteen terms of the arithmetic sequence is:
So, the sum of first eighteen terms of the arithmetic sequence is
Option B is correct option.
Answer:
It is.
Step-by-step explanation:
(x, y, z) => (4, -5, -4)
substitute 4 in x, -5 in y & -4 in z for all the equations in the system.
4x + 2y + z = 2
4(4) + 2(-5) - 4 = 2
2 = 2
5x - 4y - z = 44
5(4) - 4(-5) - (-4) = 44
44 = 44
3x + y + 4z = -9
3(4) + (-5) + 4(-4) = -9
-9 = -9
All equations therefore agree with the ordered triple.
Answer:
the two triangles are congruent because they have the same sides and angles.
To find the unit price, divide the total cost by the amount of markers. This gets you the price for one individual marker
3.96 / 6 = 0.66
The unit price is $0.66
