Step-by-step explanation:

Considering it's concept, any function with f(0) = 3 was the same y-intercept as y = 2x + 3.

The y-intercept is f(0), that is, the value of y when x = 0, which is interpreted as the initial value of the function.

In this problem, the function is given by:

y = 2x + 3.

The y-intercept is given by:

y = 2(0) + 3 = 3.

Hence, any function with f(0) = 3 was the same y-intercept as y = 2x + 3.

Answer:

BD= 56units

Step-by-step explanation:

  Since, Diagnols of a parallelogram  bisect each other.

Therefore in parallelogram ABCD where AC and BD are the diagnols wich intersect at Point E, we have, BE=DE

Therefore, x^2-21=4x

x^2-21-4x=0

x^2-4x-21=0

x^2-7x-3x-21=0      [middle term splitting]

x(x-7)+3(x-7)=0

(x+3)(x-7)=0

Hence, x= -3 and x= 7

Since x cannot be negative because no side can have negative values

Therefore, we have x=7

Now, BD= BE+DE      [Since E is the intersecting point of BD]

            = 4x+x^2-21

            = 4(7)+7^2-21

            =28+49-21= 56 units

Answer: The mirror will fit because the height of the mirror is 4 feet.

Step-by-step explanation:

we just divide 15 by 3 3/4 and get the answer of 4.

Yes, the mirror will fit on the wall because its height is approximately 4.25 feet, which is less than the 5-foot tall space on the wall.

To determine whether the mirror will fit, we need to calculate its height. Since the area of a rectangle is given by the formula Area = Height × Width, we can find the height by rearranging the formula to Height = Area ÷ Width.

The given area of the mirror is 15 15/16 square feet and the given width is 3 3/4 feet.

After performing the division, we get the height of the mirror to be approximately 4.25 feet.

Since the space on the wall is 5 foot tall and the height of the mirror is less than this, the mirror will fit on the wall. So, the answer is: Yes, it will fit because the height is 4.25 feet.

Answer:

x=5 and y=5

Step-by-step explanation:

You "plug" one equation into the other, to get a new equation that only has one variable (x or y), then you can simplify that and have your answer.

So let's plug the first into the second:

First, we convert the first equation into an x=... form. For this one, this means moving the +y to the other side:

x = 10 - y

Now we substitute 10-y for x in the second equation:

So 2x+4y=30 becomes:

2(10-y) + 4y = 30

And simplify that:

20 - 2y + 4y = 30

20 + 2y = 30

2y = 30-20

2y = 10

y = 5

This is the first answer! If we put this into the first equation, we get:

x = 10 - 5 = 5

Now we have both answers, x=5 and y=5

The value of 'a' when (a, -8) is a solution to the equation -a = 4b - 7 is '39'.

If we have the point (a, -8) as a solution to the equation -a = 4b - 7, and we're given the value of b from the point, which is -8, we can substitute this value into the equation to find 'a'.

Substituting b = -8 into the equation gives us:

-a = 4(-8) - 7

-a = -32 - 7

-a = -39

Now, we can solve for 'a' by multiplying both sides by -1 to get:

a = 39

Therefore, the value of 'a' is 39.

y + 1 = 3(x - 5)   Answer

Step-by-step explanation:

Find the slope of the perpendicular line.

m1 * m2 = - 1

m1 = - 1/3

m2 is the slope of the perpendicular

(-1/3) * m2 = - 1             Multiply both sides by -3

-(3)(-1/3) * m2 = -1 * -3  

m2 = 3

The slope of the perpendicular line is 3

Find the equation of the line.

m = (y - y1)/(x -x1)

y - y1 = m(x - x1) is the equation of the line.

y1 =5

x1 = - 1

748 trees  PLEASE GIVE BRAINLIEST

Step-by-step explanation:

b + 2c + 3jb + 2c + 3j =

88 + 2(33) + 3(44)(88) + 2(33) + 3(44) =

88 + 66 + 396 + 66 + 132 = 748 trees

After Ben spends 88 hours chopping, Cam spends 33 hours chopping, and Justin spends 44 hours chopping, they chop down a total of 286 trees.

To find the total number of trees chopped down, we'll use the given formula: ( b + 2c + 3j ), where ( b ) is the number of hours Ben spends chopping, ( c ) is the number of hours Cam spends chopping, and ( j ) is the number of hours Justin spends chopping.

Given that Ben spends 88 hours chopping ( b = 88 ), Cam spends 33 hours chopping ( c = 33 ), and Justin spends 44 hours chopping ( j = 44), we can substitute these values into the formula.

Plugging in the values:

[tex]\[ \text{Total trees} = 88 + 2(33) + 3(44) \][/tex]

Now, we calculate each term:

[tex]\[ 2(33) = 66 \][/tex]

[tex]\[ 3(44) = 132 \][/tex]

Then, we add up all the terms:

[tex]\[ \text{Total trees} = 88 + 66 + 132 \][/tex]

[tex]\[ \text{Total trees} = 286 \][/tex]

So, after Ben spends 88 hours chopping, Cam spends 33 hours chopping, and Justin spends 44 hours chopping, they chop down a total of 286 trees.

Answer:

41.1

Step-by-step explanation:

The number will be cut off after the digit you are rounding off to.

Rewrite the number, but stop at the 0.

41.0

Now you need to decide if the 0 stays as 0 or if it goes up to 1.

When the next digit is from 5 to 9, the last digit you keep goes up 1. When the next digit is 0 through 4, the last digit you keep stays as it was.

Since the first digit that was dropped is a 7, the 0 goes up one unit to 1.

Answer: 41.1

Answer:

41.1

Step-by-step explanation:

If we are rounding at the 0, we have to look at the next digit, which is 7.  

Since 7>=5, we will round up.  Zero becomes a 1

41.073  becomes 41.1

Answer: 7 hours 12 minutes

Step-by-step explanation:

Let he needs x hours to make 1 kg of meat.

Therefore, time taken in making 5 kg of meat = 5 × x = 5x hours.

But, According to the question,

He needs 12 hour to cook 5 kg of meat.

Thus, 5 x = 12

⇒ [tex]x = \frac{12}{5}[/tex] ( By dividing both sides by 5 )

⇒ He needs [tex] \frac{12}{5}[/tex] hours to make 1 kg of meat.

⇒ The time taken to cook 3 kg of meat = [tex]3\times \frac{12}{5}=\frac{36}{5} [/tex]

= [tex]7\frac{1}{5}[/tex]  hours ⇒ 7 hours 12 minutes

Hence, He needs 7 hours 12 minutes time to cook 3 kg of meat.

After calculating, we determined that Myron needs 54 minutes to cook 3 kilograms of meat.

This problem can be solved by setting up a proportion since it involves a direct ratio between the weight of meat and the cooking time.

The given ratio is 1 1⁄2 hours for 5 kilograms of meat (1:5 ratio). To find the time needed for 3 kilograms of meat, use the proportion:

    5 kg      :-      1 1⁄2 hours
    3 kg      :-       x hours

Solving for x yields the following:

    5 kg  /  3 kg  =  1 1⁄2 hours  /  x hours
             x  =  (1 1⁄2 hours × 3 kg)  /  5 kg

Converting 1 1⁄2 hours to minutes (90 minutes) and then performing the multiplication and division:

             x  =  (90 minutes × 3)  /  5
             x  =  270 minutes  /  5
             x  =  54 minutes

Thus, Myron needs to cook 3 kilograms of meat for 54 minutes.

Price in Japan= 17.81

Price in Switzerland = 13.58

Step-by-step explanation:

First set up system of equations

80.59 = 3j +2s

76.36 = 2j + 3s

Make it to where you can eliminate one variable

161.18 = 6j +4 s

-229.08 = -6j - 9s

Reset the problem

-67.9 = -5s

s=13.58

Re plug them in to the original equation to get j = 17.81

By solving a system of linear equations formed from the given information, we found the average cost of a movie ticket in Japan to be $24.60, and in Switzerland to be $6.79.

Let's denote J as the cost of a movie ticket in Japan and S as the cost of a movie ticket in Switzerland. From the problem, we establish two equations: 3J + 2S = $80.59 and 2J + 3S = $76.36. This is a system of linear equations that can be solved by substitution or elimination. If you choose elimination, add these two equations together, which results in 5J + 5S = $156.95, or J + S = $31.39. Now, substitute (J + S) in first equation, we get 3J + 2(31.39 - J) = 80.59. Solving this equation we find J = $24.60. Thus, the price of a movie ticket in Switzerland is S = $31.39 - $24.60 = $6.79. Therefore, a movie ticket in Japan costs $24.60 on average, and in Switzerland, it costs $6.79.

Answer:

$110

Step-by-step explanation:

A = P(1 + r/n)ⁿ⁺

A = 100(1 + .02/1)¹⁽⁵⁾

A =  100(1.10)

A = $110

Using the simple interest formula, you can calculate that after 5 years at an annual interest rate of 2%, an initial deposit of $100 in a savings account would grow to $110.

The subject of this question is simple interest, which is important in Mathematics. To calculate how much money would be in your account after 5 years with an interest rate of 2% per annum, you would utilize the simple interest formula:

Interest = Principal x Rate x Time (I = PRT)

The principal (P) is the initial amount of money, which is $100. The rate (R) is the interest rate per period. The time (T) represents the number of periods.

In our case: The principal is $100, the rate is 2% (or 0.02 in decimal form), and the time is 5 years. Substituting these values into the formula gives. Interest = $100 x 0.02 x 5 = $10. After 5 years, you are entitled to $10 interest. This means the total amount in your account will be your initial principal plus the earned interest: $100 + $10 = $110.
