Hence, the distance between (7,8) and (-8,0) is:17
explanation: (a,b)=(7,8) and (c,d)=(-8,0)
Answer:
-4.
Step-by-step explanation:
2x^2 - 5xy - y^3
= 2(-3)^2 - 5(-3)(-2) - (-2)^3
= 2*9 - 5(-3)(-2) - (-8)
= 18 -5*6+ 8
= 18 - 30 + 8
= -12 + 8
= -4.
Answer:
y = 2
Step-by-step explanation:
3y - 4 = 6 - 2y
→ Add 2y to both sides to isolate 6
5y - 4 = 6
→ Add 4 to both sides to isolate 5y
5y = 10
→ Divide both sides by 5 to find the value of y
y = 2
X+2,000=stocks
x=bonds
7.2%⇒(.072)(x)=bonds invested
6%⇒(.06)(x+2,000)=stocks invested
Here is the equation:
x(.072)=(.06)(x+2,000) | Since the income from both equal
You then solve each side first (assume you know how to but if not, let me know)
You first multily the parentheses/x variables
⇒.072x = .06x+2,000(.06)
⇒.072x = .06x+120
You then minus .06x from each side
⇒.012x = 120
You then divide each side by .012
.012x÷.012=x
120÷.012=10,000
x=10,000
Now change the original x variables with 10,000
.072($10,000)=$720 bond interest
<u>They are equal so $720×2=$1440</u>
The correct answer is D since a function can only map one input one output.
