Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (5, - 8)
m = 
= 
= - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 1) , then
1 = - 6 + c ⇒ c = 1 + 6 = 7
y = - 3x + 7 ← equation of line
Answer:
A I guess
Step-by-step explanation:
I tryed my best
I'm assuming you want us to solve this inequality for x, since the question wasn't too clear on that.
Add 35 to both sides to remove the "-35" on the left side so we can isolate the x
The solution to this inequality is x>50. Let me know if you need any clarifications, thanks!

Answer:
-1078
Step-by-step explanation:
To find the nth term in an arithmetic sequence we use the following formula
aₙ=a₁+(n-1)*d
Where a₁ is the first time, and d is the common difference (in this case -20)
So we have
2+(55-1)*-20
2+(54)*-20
2-1080
-1078
Answer:
Her mistake was not multiplying both sides of the equation by 0.5
Step-by-step explanation:
The mistake is in Step 1--Tiffany was correct in multiplying the left side (h / 0.5) by 0.5 but made an error on the right side by dividing the 7 by 0.5 instead of multiplying.
<em>Thus, h= 3.5</em>
