Step-by-step explanation:
all are correct
Answer:
-12
-10
-5
-14
Step-by-step explanation:
First, you want to do inverse operations
M/-5 < 3
Just multiply -5 with 3
You have to flip the inequality sign because you multiplied by a negative
Answer: M > -15
Now what is greater than -15?
Answer =
-12
-10
-5
-14
X - 2y = 3
<span>4x^2 - 5xy + 6y = 3
lets solve for x the first and substitute in the second:
x = 3 + 2y
4(</span>3 + 2y)^2 - 5(3 + 2y)y + 6y = 3
4(9 + 12y + 4y^2) - 15y - 10y^2 = 3
36 + 48y +16y^2<span> - 15y - </span><span>10y^2 = 3
6y^2 + 33y + 33 = 0
we can solve using the general quadratic formula:
y = (-33 +- </span>√(33^2 - 4*6*33)<span>)/12
</span>y = (-33 +- √(297)<span>)/12
</span>so there are 2 solutions for y:
y1 = (-33 + √(297)<span>)/12
</span>y2 = (-33 - √(297)<span>)/12
</span>pick one and then substitute the y value in the first equation to find x
Okay, so here we go:
This is what went into her bank account:
15.60+42= 67.60
This is what came out:
43+12+25.70= 80.70
105.65- 67.60 + 80.70= 92.55
92.55 is the ending balance.
Hope this helped you!
Answer:
<h2>
12q</h2>
Step-by-step explanation:
Given P = 6q² + 3, we are to find the derivative of the function with respect to q. Generally if y = axⁿ;
dy/dx = naxⁿ⁻¹
Rewriting the given equation as P = 6q² + 3q⁰
Using the formula to find the derivative;
dP/dq = 2(6)q²⁻¹ + 0(3)q⁰⁻¹
dP/dq = 12q¹ + 0
dP/dq = 12q
<em>Hence the derivative of the function P with respect to q is 12q</em>
