Answer:
Slope = -2
Y intercept = 4
Equation. y = -2x +5
Step-by-step explanation:
Using points, (1,2) and (3,-2)
Slope = (-2-2)/(3-1) = -4/2 = -2
Y intercept = 4
-2 = (y-3)/(x-1)
-2(x-1) = y-3
-2x +2 = y-3
y = -2x +2 +3
y = -2x +5
Answer:
42
Step-by-step explanation:
a = 2, b = 5, and c = 1
- a*(4b + c²) = ⇒ plug in values
- 2*(4*5 + 1²) = ⇒ solving exponents
- 2*(20 + 1) = ⇒ parenthesis
- 2*21 = ⇒ multiplication
- 42 ⇒ answer
Answer: multiply 8 on all x number of books read
Step-by-step explanation:
1 is 8 because 8 × 1 is 8
2 is 16 because 8 × 2 is 16
3 is 24 because 8 × 3 is 24
4 is 32 because 8 × 4 is 32
5 is 40 because 8 × 5 is 40
6 is 48 because 8 × 6 is 48
7 is 56 because 8 × 7 is 56
8 is 64 because 8 × 8 is 64
9 is 72 because 8 × 9 is 72
10 is 80 because 8 × 10 is 80
Answer:
Step-by-step explanation:
y = 3x + 4
Plugin x = 3 in the equation,
y = 3*3 + 4
= 9 + 4
y = 13
Plugin x = 4 in equation,
y = 3*4 + 4
= 12 + 4
y = 16
Plugin x = 5 in the equation,
y = 3*5 + 4
= 15 + 4
y = 19
2) y =x - 7
Plugin x = 10 in the equation
y = 10 - 7
y = 3
Plugin x = 15 in the equation
y = 15 - 7
y = 8
Plugin x = 20 in the equation
y = 20 - 7
y = 13
