The answer is x+2 and x-1
2(0.5c-1.5)-6=-2
Move all terms to the left
2(0.5c-1.5-6-(-2)=0
Add all the numbers together, and all the variables
2(0.5c-1.5)-4=0
Multiple parentheses
0c-3-4=0
Add all the numbers together, and all the variables
c-7=0
Move all terms containing c to the left, all other terms to the right
c=7
use the equation is over of equals percent over 100 so it would x over 289 equals 24 over 100. and then you cross multiply and then find x.
Point slope form is written as:
y - y_1 = m * (x - x_1), where y_1 and x_1 are the y and x coordinates of the given point and m is the slope.
The slope, we know, is -6, and the given point is (-2, -4). Plug these into the equation:
y + 4 = -6 * (x + 2)
And, that's your answer!
Answer:
AC ≈ 12.9 cm
Step-by-step explanation:
Using the ratio
sin40° =
Multiply both sides by 20
20 × sin40° = b, hence
AC = b = 20 × sin40° ≈ 12.9
