Answer:
Lucy had 40 books last year.
Step-by-step explanation:
assuming 100% is the percent;
100% + 70%
100 : x
170 : 68
cross multiply = 170x = 100 x 68
-------- ————-
170 170
cancel 170/170
therefore x = 100 x 68 divided by 170
result is 40
Answer:
-2
Step-by-step explanation:
slope form: y2-y1/x2-x1
points: x1, y1 (2,7) and x2,y2 (-4,19)
substitute the points into the form: 19-7/-4-2
simplify: 12/-6 = -2
Answer:
C
Step-by-step explanation:
Given
f(x) = x² + x + 1
To express in vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² + x
x² + 2(
)x + 
- + 1
= (x + )² + 
→ C
When the X value is zero, the Y value is negative two.
