h=-3/2 and h=-11/2

Step-by-step explanation:

There are two solutions for h it is:

2h+7=4 and 2h+7=-4

Lets do 2h+7=4

2h=-3 (Move the 7 to the other side)

h=-3/2 (Answer)

Lets do 2h+7=-4

2h=-11 (Move the 7 to the other side)

h=-11/2 (Answer)

Answer:

h=-3/2, -11/2

Step-by-step explanation:

There are two solutions for h

2h+7=4 and 2h+7=-4

2h+7=4:

Move the 7 to the other side to eliminate the 7 on the left side: 2h=-3

divide: h=-3/2

h=-3/2

2h+7=-4:

Move the 7 to the other side to eliminate the 7 on the left side: 2h=-11

divide: h=-11/2

h=-11/2

Answer:

[tex]x=\{\frac{3\pi}{4}, \frac{7\pi}{4}\}[/tex]

Step-by-step explanation:

For the tangent line to be horizontal, the derivative of the function at that point must be 0.

Thus, let’s first take the derivative of our function:

[tex]f ^\prime(x)=\frac{d}{dx}[\cos(x)-\sin(x)][/tex]

Differentiate:

[tex]f^\prime(x)=-\sin(x)-\cos(x)[/tex]

Now, let’s set our derivative equal to 0:

[tex]0=-\sin(x)-\cos(x)[/tex]

Let’s multiply everything by a negative:

[tex]0=\sin(x)+\cos(x)[/tex]

To solve for x, we can subtract sin(x) from both sides. This gives us:

[tex]\cos(x)=-\sin(x)[/tex]

Now, we can refer to the unit circle. First, remember that the only points for which cosine is equal to sine is at the π/4 points. That is, π/4, 3π/4, 5π/4 or 7π/4.

However, cosine is equal to negative sine. The only two quadrants for which cosine and sine are the same but also have opposite signs is QII and QIV.

Therefore, our answers are 3π/4 and 7π/4.

The amount is 440.71

Step-by-step explanation:

"The electric bill reflected a monthly fee of $42.00 as well as a kilowatt per hour charge of $0.0953 for electricity used. Which function determines the amount of electricity used based on the total bill cost? Group of answer choices"

Given data

monthly fee= $42

kilowatt per hour charge=$0.0953

let the number of hours be =x

let the expression be patterned after the model\

y=mx

here  y=42

m=0.0953

We want to find x, the amount of electricity used

42=0.0953x

divide both sides by 0.0953 we have

42/0.0953=x

x=440.71

The zero value of the function occurs at s = 4

Step-by-step explanation:

The given function for the amount of money, m, Jason has left after buying s number of sno-cones for his friend is m = 5 - 1.25·s

Therefore, we have generated from Microsoft Excel the following data table used to plot the points on the graph

Number of Sno-cones          [tex]{}[/tex]        Amount of money left

0                                    [tex]{}[/tex]                        5

1                                    [tex]{}[/tex]                         3.75

2                                    [tex]{}[/tex]                        2.5

3                                    [tex]{}[/tex]                        1.25

4                                    [tex]{}[/tex]                        0

Therefore, as seen from the above table, and from the attached graph, the zero value of the function occurs at the value where the amount of money left (y-coordinate value) is 0 which is at the value of s = 4.

Answer:

18000

Step-by-step explanation:

4500=1/4 of year

to get year we x 4

4500x4=18000 dollars

Ms. Lisak’s yearly salary will be equal to $18000.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Ms. Lisak’s salary is $4,500 quarterly. Yearly salary will be calculated by making an expression as below,

Multiply the quarterly salary by 4.

4500=1/4 of year

To get a year we multiply by 4.

4500x4 = 18000 dollars

The yearly salary will be $18000.

Step-by-step explanation: HALP

Answer:

Question 2: D. 604.9

Question 3: 80 oranges or 10/30 or 1/3

Step-by-step explanation:

For question 2:

Okay so, Hal has 5 3/4 bags of munch and each bag covers 105.2 area. We can take the whole number that is already there (5) and multiply it by 105.2 since it is the amount of 1 full bag. So: 5(105.2) is equal to 526.

Now we have to figure out how much 3/4 of a bag is. So take the amount of the full bag and divide it by the denominator (4). So: 105.2/4 is equal to 26.3. Now we know that for 1/4 of a bag it can cover 26.3. We are trying to find the 3/4 so take 1/4 and multiply it by 3 to get 3/4. We can do the same to the amount it is equal with: 26.3(3) and you get 78.9 as an amount of 3/4 of a bag of munch.

Now we add the 3/4 and 5 whole bags: 526.0+78.9=604.9

Our final answer is 604.9 so, option D is correct.

For question 3:

Basically taking all the given fractions: 1/5, 1/6 and 3/10. The lowest amount I can think of is multiplying the denominators to get 30 since they can all equal to 30. So multiply the denominator and numerator for each fraction:

1/5x6=6/30

1/6x5=5/30

3/10x3=9/30

Notice that the denominators are all equal to 30 so this allows us to now add them together.

6/30 + 5/30 + 9/30 = 20/30

Now we know that all together 20/30 is the already know fruits we can easily assume the 10/30 is the amount of oranges. We need to figure out the whole number and not the fraction so, take 240 and divide it by the denominator (30) and we get how much 1/30 is worth in a whole number. So: 240/30=8.

Now we know that 1/30=8 pieces of fruit. Take the 20/30 for already known fruit and we get 160. Take the 10/30 for oranges and we get: 10/30(8) is equal to 80 oranges.

So:

80 oranges

160 other known fruits

Basically 160=2/3 and 80=1/3.

We can check if this is true by:

2/3 (known fruit) and multiply the denominator and numerator by 10 to get 30:

2/3(10)= 20/30. We know this correct because 20/30 is the same as the known fruits fraction we got earlier. Next 1/3(10)=10/30 the 10/30 that was also equal to the amount of oranges.

Our final answer is 80 oranges or 10/30 or 1/3

I hope this helps:)

Answer:

well shiet

Step-by-step explanation:

y=5/3x+9 is the slope intercept form of the equation of line   20x-12y=-108

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The given equation is 20x-12y=-108

We need to write this equation in the form of slope intercept form.

To do this we have to isolate the y term

-12y=-108-20x

Now divide both sides by 12 and multiply with minus.

y=9+20/12x

y=9+5/3x

y=5/3x+9 is the required equation.

Hence,  y=5/3x+9 is the slope intercept form of the equation of line   20x-12y=-108
