Answer:
Option C
Step-by-step explanation:
All of these equation have a slope of x=-3, as this is the only number that will be acompanied by an x (the slope of a function is the number on the equation that has an X). To know which one of this equations passes through the points (7;-2) we can supplant these numbers on each equation until the result at both sides are equals.
The correct answer is the option c, because if we supplant these numbers (x=7 and y=-2) on the equation, we get an equality.
Answer:
x = 466.7 ft
Step-by-step explanation:
The lower angle in the right triangle = 31° ( alternate angle )
Using the cosine ratio in the right triangle, with hypotenuse x
cos31° = 
= 
Multiply both sides by x
x × cos31° = 400 ( divide both sides by cos31° )
x = 
≈ 466.7
If B is between A and C, and AB=3x+1, BC=2x-7, and AC=24, then find the value of x and the value of AB
let assume AC is straight line and B is on line
AB + BC = AC
3x+1 +2x -7 = 24
5x -6 = 24
5x = 30
x = 6
Answer:
37.66
Step-by-step explanation:
C because if you solve for the solutions for the quadratic, then you get 5 and -1 but you cant have negative seconds so 5 is the right answer!
