Answer:
-1
Step-by-step explanation:
Derivative of cos(x)=-sin(x)
Derivative of e^x=e^x
Derivative of cos(x)-e^x= - sin(x)-e^x
plug in 0 to the spots of x and you will get 1 because sin(0) is 0 e^0 is 1

Abe is buying wrapping paper.
He is shopping for the best deal.
Drag the rolls of wrapping paper in order from the least to the greatest unit cost in dollars per square foot.
red 12.5 square feet for $1.79
blue 40 square feet for $5.29
green 50 square feet for $8.49
orange 60 square feet for $6.00
Answer:
So you need to compute all the rates to see which is the best deal.
$1.79/12.5ft^2=$0.1432 per ft^2
$5.29/40ft^2=$0.13225 per ft^2
$8.49/50ft^2=$0.1698 per ft^2
$6/60ft^2=$0.10 per ft^2
So the last option is the cheapes per square foot and thus is the best deal. Ordered from least to greatest.
Sherbert, blue, red, and green
Step-by-step explanation:
hope this helps
Answer:
The order goes Orange, Blue, Red, and Green
Step-by-step explanation:
By dividing the total cost by the amount of square feet, you get the unit value for the wrapping paper per square foot.

I need help finding the domain
Answer: [-11,4]
Step-by-step explanation:
yes in brackets
Answer:
(-11, 4)
Step-by-step explanation:
The domain is the x values that the equation/line covers.
The line starts at -11 and ends at 4. We use parenthesis instead of brackets since the circles are open and not closed.
Solve: -4(3-2x) = 6(3x + 3)
Step by step ?
Answer:
distribute the -4 to the 3 and -2x in the parentheses
-12+8x
distribute the 6 to the 3x and the 18
-12+8x = 18x+18
subtract 8x from both sides
-12= 10x+18
subtract 18 from both sides
-30= 10x
divide each side by 10
x= -3

Step-by-step explanation:
Suppose that you need to buy some chicken for dinner tonight. You found an ad showing that a store across town has chicken on sale for $2.99 per pound. Your usual neighborhood store sells the same chicken for $3.79 per pound. You are considering whether it is worth the drive to purchase the chicken from the store across town. Information you will need:________
A. You need to purchase 3 pounds of chicken
B. Your neighborhood store is 2.1 miles away and takes about 8 minutes to get there
C. The store across town is 8.6 miles away and takes about 24 minutes to get there
D. Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon
Answer:
C). The store across town is 8.6 miles away and takes about 24 minutes to get there.
D). Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon.
Step-by-step explanation:
The information regarding the distance of the store across town from the house, the time required to reach there, the average of the car, and the cost of gas per gallon would assist in calculating if the extra drive is worth buying chicken from the city store.
Cost of chicken in the city store - $2.99 per pound
Average of the car in 1 gallon = 22miles
so, the average of the car in 1 mile = 1/22
Cost of traveling 8.6miles = 8/22 * $3.05
= 24.40/22
Additional cost = $ 1.109
Total cost of buying chicken from the city store = $2.99 + $1.10
= $4.09
Hence, it is not worth to buy the chicken from the store across the town as it is costlier in comparison to $3.79 in nearby store.
solve for x.
a) 9[tex]9^{3x+4}[/tex] = [tex]27^{4x+3}[/tex]
b) [tex]4^{3x}[/tex] = [tex]2^{x+1}[/tex]
(include steps pleez)
Answer:
Question a)
[tex]9^{3x+4}=27^{4x+3}[/tex]
[tex]x=-0.166[/tex]
Question b)
[tex]4^{3x}=2^{x+1}[/tex]
[tex]x=0.2[/tex]
Step-by-step explanation:
Question a)
Given the expression
[tex]9^{3x+4}=27^{4x+3}[/tex]
Taking log on both sides
[tex]log\left(9^{3x+4}\right)=log\left(27^{4x+3}\right)[/tex]
[tex]\left(3x+4\right)\cdot \left(log\left(9\right)\right)\:=\left(4x+3\right)\cdot \left(log\left(27\right)\right)[/tex]
[tex]3x+4=\left(\frac{log\left(27\right)}{log\left(9\right)}\right)\cdot \left(4x+3\right)[/tex]
[tex]3x+4=1.5\times \left(4x+3\right)[/tex]
[tex]3x+4=6x+4.5[/tex]
[tex]3x=6x+0.5[/tex]
[tex]\frac{-3x}{-3}=\frac{0.5}{-3}[/tex]
[tex]x=-0.166[/tex]
Therefore, the value of x:
[tex]x=-0.166[/tex]
Question b)
Similarly, we can solve the 'b' expression
Given the expression
[tex]4^{3x}=2^{x+1}[/tex]
Taking log on both sides
[tex]log\left(4^{3x}\right)=log\left(2^{x+1}\right)[/tex]
[tex]3x\cdot \left(log\left(4\right)\right)=\left(x+1\right)\cdot \left(log\left(2\right)\right)[/tex]
[tex]3x=\left(\frac{log\left(2\right)}{log\left(4\right)}\right)\cdot \left(x+1\right)[/tex]
[tex]3x=0.5\times \left(x+1\right)[/tex]
[tex]3x=0.5x+0.5[/tex]
[tex]2.5x=0.5[/tex]
Divide both sides by 2.5
[tex]\frac{2.5x}{2.5}=\frac{0.5}{2.5}[/tex]
[tex]x=0.2[/tex]
Therefore, the value of x = 0.2

Expand.
a)3(x - 2)
b)2(y + 4)
c)8(3 + x)
Answer:
[tex]a \: 3x - 6 \\ b \: 2y + 8 \\ c \: 8x + 24[/tex]
Step-by-step explanation:
All we have to do is multiply accordingly. I'll use a for an example.
So for the value before the perentheses we multiply that by all of the values in the perentheses.
[tex]3x \: and \: - 6[/tex]
So the correct answer would be
[tex]3x - 6[/tex]
You can use the same strategy for all the questions, but I'll just answer those straight away.
Also you may notice I put the variable before the constant in question c because the variable should always go before the constant in expressions and equations.
Sean wants to spend (example) $100 on clothing and he wants to purchase
6 additional items for his wardrobe. Each pair of pants costs $20 and each shirt costs $15.
Show the solution graphically.
Point (2, 4)
Answer:
Step-by-step explanation:
Let x be the number of pants and y be the number of shirts
x + y = 6
20x + 15y = 100
multiply the first equation by -20
-20x -20y = -120
20x + 15y = 100
subtract the equations
-5y = -20
y = 4
replace y in equation 1
x + 4 = 6
x = 2

Which of these equations is NOT true?
A) 2(a + b) = a +b+a+b
C) (t-4) +6=t-10
B) 3y + 4y = 7y
D) x(5 + 9) - x = 13x
Answer:
C) (t-4) + 6=t-10
Step-by-step explanation:
2(a+b)= a+b+a+b
2(a+b)= 2a+b+b
2(a+b)=2a+2b
2(a+b) = 2(a+b)✅
(t-4)+6=t-10
t+2=t-10❌
3y+4y=7y
7y=7y✅
