Answer:
The 43rd day of spending $45.
Step-by-step explanation:
Let the number of days = x.
If she spends $45 per day, then in x days she spends 45x.
She starts with $2400, so 45x is subtracted from 2400.
2400 - 45x < 500
Subtract 2400 from both sides.
-45x < -1900
Divide both sides by -45. Remember to change the direction of the inequality sign when multiplying or dividing by a negative number.
x > 42.2
Answer: The first day is the 43rd day of spending $45.

Solve the equation 3(m + 5) = 3 + 3(2m + 2) for m.
Answer:
m=2
Step-by-step explanation:
Answer:
[tex]m=2[/tex]
Step-by-step explanation:
[tex]3\left(m+5\right)=3+3\left(2m+2\right)[/tex]
Expand:
[tex]3m+3\times5=3+3\times2m+3\times2[/tex]
[tex]3m+15=3+6m+6[/tex]
[tex]3m+15=6m+9[/tex]
Subtract 15 from both sides:
[tex]3m+15-15=6m+9-15[/tex]
[tex]3m=6m-6[/tex]
Subtract 6m from both sides:
[tex]3m-6m=6m-6-6m[/tex]
[tex]-3m=-6[/tex]
Divide both sides by -3:
[tex]\frac{-3m}{-3}=\frac{-6}{-3}[/tex]
[tex]m=2[/tex]

solve for T
10t = -50
Answer: t=-5
Step-by-step explanation:
if 10t=-50, you have to solve for the equation. to solve, you have to get the variable by itself. to get the variable by itself, you have to divide both sides by 10. 10t/10=-50/10. t=-5

Over which interval is the graph of y= cos(x) strictly increasing?
A. 0 B. 0 C.pi/2D. Pi< x <2pi
Answer:
D. [tex]\pi<x<2\pi[/tex]
Step-by-step explanation:
Given the function
[tex]y=cosx[/tex]
Kindly refer to the graph attached in the answer area.
Referring to the intervals [0, [tex]2\pi[/tex]].
It decreases from the interval [0, [tex]\pi[/tex]] and then starts increasing in the interval
[tex][\pi,2\pi][/tex].
Proving by taking derivative:
Taking derivative of the function, [tex]y=cosx[/tex]
[tex]\dfrac{dy}{dx}=-sinx[/tex]
In the interval [tex][\pi,2\pi][/tex], [tex]sinx[/tex] is negative i.e. [tex]sinx<0[/tex].
Therefore [tex]-sinx>0[/tex]
When, the derivative of a function is positive, then the function is strictly increasing.
So, the answer is:
D. [tex]\pi<x<2\pi[/tex]

Solve: 4(x-1)-3(3x-2)=12(x+2)
Answer:
4x - 4 -9x + 6 = 12x + 24
arrange like terms
-5x +2 = 12x + 24
or, -17x = 22
x = - 22/17
Answer:
4x-4-9x+6=12x+24
4x-12x-9x= 4-6+24
-17 x= 22
X= -22/17

Step-by-step explanation:
E varies directly with G. When G is 6, E is 10. Find the value of G when E is 18.
Answer:
10.8
Step-by-step explanation:
E has increased by a factor of 18/10 = 1.8, so G will increase by that factor. The corresponding value of G is ...
6 × 1.8 = 10.8 = G
__
If you like, you can write an equation relating G to E:
E = kG
10 = k(6)
k = 10/6 = 5/3
Now for E = 18, we have ...
18 = (5/3)G
18(3/5) = G = 10.8
