Answer:
y = -x+4
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 4-3)/(0-1)
= 1 /-1
= -1
The y intercept is (0,4) or 4
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -x+4
Answer:
p=30
Step-by-step explanation:
First, you need to subtract 10 from both sides to get 1/2p=25. You do this just because simplifying is much easier.
Then, you need to isolate p, so you divide 1/2 by both sides, which is the same thing as multiplying by 2. 1/2*2p=15*2.
Simplifying, you get p=30.
A = 7n + 2
a₁ = 7*1 + 2 = 9
a₂ = 7*2 + 2 = 16
a₃ = 7*3 + 2 = 23
.

.
a₂₀ = 7*20 + 2 = 142
This is an Arithmetic progression, a = 9, last term = 142
Sum of the 20 terms using: n/2(a + l) where l = last term.
= 20/2(9 + 142)
= 10 * 151
= 1510
Sum of the first 20 terms = 1510
If those are the only numbers that are given the most logical answer would be 12 since 52-32=20 and 32-20=12
