Answer:
B
Step-by-step explanation:
The slope of this function is obviously decreasing, and the point where it intersects the y axis, is (0,-2)
Answer B contains this information
Hope this helps!
Answer:
for 7% , $8,000
for 8.5%, $4,000
Step-by-step explanation:
Key amount at 7% be x and amount at 8.5% be y
Mathematically;
x + y = 12,000 ••••••(i)
Let’s now work
with the interest;
7% of x + 8.5% of y = 900 ••••••(ii)
0.07x + 0.085y = 900
So we have two equations to solve simultaneously
From 1, x = 12,000-y
Substitute this into ii
0.07(12000-y) + 0.085y = 900
840-0.07y + 0.085y = 900
0.015y = 900-840
0.015y = 60
y = 60/0.015
y = 4000
x = 12000-4000
x = $8,000

Trying to factor as a Difference of Squares
2.1 Factoring: 25a2-b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 25 is the square of 5
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (5a + b) • (5a - b)
