Answer:
The slope is 0.
Step-by-step explanation:
m= (y2-y1)/(x2-x1).
y2 is -3, y1 is -3.
x2 is 1 and x1 is -9.
m= -3 -(-3)/ 1- (-9)
m= 0/10
m=0
Answer:
(5,2) and (5,10)
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
we have
substitute in the formula
solve for y
square both sides
square root both sides
therefore
The points are
(5,2) and (5,10)
Use the substitution method
f(x)= 3-2x
f(4)= 3-2(4)
Do multiply first then subtract
= 3-8
= -5
Answer : f(4)= -5
(1 / 5) hour is 12 minutes and five times this equals 1 hour.
So the distance times 5 equals miles per hour.
(3 / 4) * 5 = 15 / 4 = 3.75 mph
Answer:
Hi there!
The correct answer is: (x+8)² = 73
Step-by-step explanation:
First you want to modify the equation: x² + 16x - 6 = 3 into x² + 16x = 9 by adding 6 on both sides.
Then you analyze the new equation, if you can see, 16x is positive which means two positive numbers have to be added up to equal a positive. Which eliminates the choices that have (x-8)²
And now you are left with two choices:
(x+8)² =73 and (x+8)² = -55
Now remember, when you factor out (x+8)² it equals to x² + 16x + 64
next let's bring it back to the very first equation: x² + 16x = 9
now which choice matches the result x² + 16x = 9. The answer will be (x+8)² = 73 because when you subtract 64 on both sides you get 9.
