Answer:
1. slanting upward because the slope is positive one.
2. A: 3/4 B: 4/-3
3. A: 3 B: y=3x-10
1. (-2-7)/(-4-5) = -9/-9 = 1
2. A: (7-4)/(7-3) = 3/4
B: (8-0)/(-6-0) = 8/-6 = 4/-3
3. find the slope first so (4-1)/(2-1)= 3/1. then you plug in point C to find the y intercept so y=mx+b would be 2=3(4)+b which makes it so b is -10. the new equation would be y=3x-10

Answer:
(f + g)(x) = x² + 4x - 4
Step-by-step explanation:
The statement (f + g)(x) is the same as f(x) + g(x). In other words, the question simply wants you to add the two functions together.
f(x) = 4x + 1
g(x) = x² - 5
(f + g)(x) <----- Original statement
f(x) + g(x) <----- Rewrite
(4x + 1) + (x² - 5) <----- Substitute the equations in f(x) and g(x)
4x + x² - 4 <----- Add 1 and -5
x² + 4x - 4 <----- Rearrange the terms
I dont know the log in so guess and you have chance to do it y=log
The lateral surface of a cylinder can be found with the equation
A = 2 π r h Substitute in your values.
A = 2 π (11) (7) Multiply 11 and 7.
A = 2 π (77) Multiply 77 and 2.
A = 154π Don't simplify anymore so you can keep pi in the answer.
The surface are uses the equation
A = 2 π r h + 2 π r² Substitute in your values.
A = 2 π (11) (7) + 2 π (11)² Simplify and multiply your terms.
A = 2 π (77) + 2 π (11)²
A = 154 π + 2 π (11)²
A = 154 π + 2 π (121)
A = 154 π + 242 π Since both terms are in terms of pi, you can combine them.
A = 396π Stop simplifying to leave the answer in terms of pi.
