3. r^2 + 2r - 35 4. a^2- 11a + 28
(r + 7)(r - 5) (a - 7)(a - 4)
5. m^2 - 6m - 7 6. m^2 - m - 2
(m + 1)(m - 7) (m - 2)(m + 1)
7. n^2 - 4n + 3 8. b^2 - 4b - 5
(n - 3)(n - 1) (b - 5)(b + 1)
Since ABC and DEF are similar then we can write:.
CB/FE = CA/FD
9/90 = b/360
b/360 = 1/10
b = 360/10
b = 36
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
well, to get it all we need is two points, say hmmm let's use (-1 , -7) and (7 , 25)
Number of children that enrolled in a day care center last year = 120
Number of children that enrolled in a day care center this year = 144
Difference in the number of children = 144 - 120
= 24
Percentage of increase = (24/120) * 100
= 20 percent.
From the above deduction, we can conclude that the correct option is option "B".
Take h common:
h(B + r) = 25
Divide b+r
h = 25/ b + r
Subtract bh:
hr = -bh + 25
Divide h:
r = -bh/h + 25/h
Simplify:
r = -b + 25/h
Hope this helps!
