can you help me with this please
Answer:
a) y = 2 x - 1
b) y = - x + 7
c) y = 7 x + 2
Step-by-step explanation:
Use a pair of (x1, y1) and (x2, y2) points to find the equation of the line for each tables:
a) (5, 9) and (10, 19)
slope: (y2 - y1) / (x2 - x1) = (19 - 9) / (10 - 5) = 10 / 5 = 2
Then y = 2 x + b
solve for b in: 9 = 2 (5) + b
b = 9 - 10 = -1
Then y = 2 x - 1
b) (2, 5) and (5, 2)
slope: (y2 - y1) / (x2 - x1) = (2 - 5) / (5 - 2) = -3 / 3 = -1
Then y = - x + b
solve for b in: 5 = - (2) + b
b = 5 + 2 = 7
Then y = - x + 7
c) (3, 23) and (6, 44)
slope: (y2 - y1) / (x2 - x1) = (44 - 23) / (6 - 3) = 21 / 3 = 7
Then y = 7 x + b
solve for b in: 23 = 7 (3) + b
b = 23 - 21 = 2
Then y = 7 x + 2

What are the solutions to the equation y^2-1 = 80?
Answer:
y^2-1=80
y^2=81
y = positive and negative 9
y2−1=80
Step 1: Add 1 to both sides.
y2−1+1=80+1
y2=81
Step 2: Take square root.
y=±√81
y=9 or y=−9
Answer:
y=9 or y=−9

PLEASE HELP ASAP! DO IN 5 MINUTES! WILL MARK BRAINLIEST!!!!!!
Answer:
Step-by-step explanation:
cos²(x) = 1-sin²(x) = 144/169
cos(x) = √(144/169) = 12/13
:::::
tan(x) = sin(x)/cos(x) = (5/13)/(12/13) = (5/13)×(13/12) = 5/12

Given the first term and the common ratio of a geometric
sequence find the first five terms and the explicit formula. a1
= 0.8, r= −5
Answer:
nth term = 0.8 * -5^(n - 1)
First five terms are: 0.8, -4,
20, -100, 500
Step-by-step explanation:
First term, a1 = 0.8
Common ratio, r = -5
a1 = 0.8
Second term = ar
= 0.8 * -5
= -4
Third term = ar²
= 0.8 * -5²
= 0.8 * 25
= 20
Fourth term = ar³
= 0.8 * -5³
= 0.8 * -125
= -100
Fifth term = ar⁴
= 0.8 * -5⁴
= 0.8 * 625
= 500
First five terms are: 0.8, -4,
20, -100, 500
nth term = ar^(n - 1)
= 0.8 * -5^(n - 1)
nth term = 0.8 * -5^(n - 1)
0.6 + 15 b + 4 = 25.6.
Answer:
0.6 + 15b + 4 = 25.6
15b +4 = 25
15b = 25 - 4
15b = 21
b = 21/15
b = 7/5
hope it helps
Answer:
Exact Form:
b=7/5

what is the area of a rectangle whose length is (2x-1) cm and whose width is (X+2) cm?
help.
Answer:
2x^2 + 3x - 2
Step-by-step explanation:
=> area of rectangle = length*width
=> length = (2x -1)
=> width = (x + 2)
=> area = (2x - 1) (x + 2)
=> area= 2x(x + 2) - 1(x + 2)
=> area = 2x^2 + 4x - 1x - 2
=> area = 2x^2 + 3x - 2
hope it helps
