- Division
- Addition
- Subtraction
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x, y) = 2x - 3y + xy²
(3, -1) is x =3 and y = -1
<u>Step 2: Evaluate</u>
- Substitute: f(3, -1) = 2(3) - 3(-1) + 3(-1)²
- Exponents: f(3, -1) = 2(3) - 3(-1) + 3(1)
- Multiply: f(3, -1) = 6 + 3 + 3
- Add: f(3, -1) = 9 + 3
- Add: f(3, -1) = 12
Answer:
parallel : (b) and (g)
perpendicular : (d) and (f)
Step-by-step explanation:
straight line equation : y = mx + c
Lines that are parallel have the the same gradient(m),
(b) and (g) are parallel, both of them has m= 1/2
Lines that are perpendicular will have the product of their
gradient(m) equal to -1. So, m1 × m2 = -1
(d) and (f) are perpendicular, because : -4 × ¼ = -1
Hope I was able to help:))
Answer: 5) r = 5, 8th term = -78,125
6) r = 5, 8th term = -312,500
7) r = 5, {1, 5, 25, 125, 625}
8) r = 5, {-4, -20, -100, -500, -2500}
<u>Step-by-step explanation:</u>
The explicit formula of a geometric sequence is: 
, where;
- n is the number of the term
- a₁ is the first term
- r is the common ratio
