Answer: 
note: replace 'j' with any other letter you want, assuming your book does not use this letter.
=============================================
Explanation:
j = jenny's score
t = Terrance's score
(4/5)*t = 4/5 of Terrance's score
(4/5)*t+5 = 5 points greater than 4/5 of Terrance's score
represents the inequality connecting Jenny's score and Terrance's score. Saying "her score is no less than some amount" is basically saying "the lowest her score can go is that amount". A specific example: if we say "her score is no less than 12" then this means "her score is 12 or more" and we can write 
Step-by-step explanation:
its 1/4 of the circle
circle circumference:
we need 1/4 of it, so its

Answer:
y = 
Step-by-step explanation:
The equation used to find the equation for a line with two intercepts is called point slope form. 
, where 
and 
are the intercept points and m is the slope.
However, we need the slope to use this formula.
Use 
m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}
y - ( -7 ) = m ( x - ( 4 ) )
y - ( -7 ) = -7/4 ( x - ( 4 ) )
y + 7 = -7/4 ( x + 4 )
y + 7 = 
y + 7 = 
y + 7 = 
y + 7 = - 7
y =
