Answer:
Step-by-step explanation:
7) 2ab + 4ac = 2*a*b + 2 *2 *a*c
= 2a(b + 2c)
8) ac - a²c² = c( a - a²c)
bc - abc = c(b - ab)
9) b²+ 4b - 5 = b² + 5b - 1b - 5
= b(b + 5) - 1(b + 5)
= (b +5)(b - 1)
b² + 8b + 15 = b² + 5b + 3b + 15
= b(b + 5) + 3(b + 5)
= (b + 5 )(b + 3)
Answer:
the average weight of one peach is 6.4 ounces
Step-by-step explanation:
10lb of peaches
16 ounces in a pound
10 x 16 = 160 ounces
divide 160 (ounces) by 25 (Peaches)
= 6.4 ounces per peach
Answer:
find the least common multiple for the denominator and multiply with the numerator
for the first one,
Step-by-step explanation:
the common multiple for 4 and 6 is 12
4×3=12
6×2=12
multiply the same numbers with the numerator
1×3=3
5×2=10
the answer is 3/12 and 10/12
Subtract the difference:
14,649 - 2389 = 12,260
Divide that by 2
12,260 / 2 = 6,130
That is the number of shows for B.
For A add the 2,389 to the number of shows for B
2389 + 6130 = 8,519
Show A = 8,519
Show B = 6,130
The line segment goes through (-2,3) and (1,-3).
The slope of the line is
Therefore the equation of the line segment is of the form
y = -2x + b
Because the line segments goes through (-2,3), therefore
-2(-2) + b = 3
4 + b = 3
b = -1
Answer: The equation is y = -2x - 1
