Answer:

Step-by-step explanation: If you add 19 and 17 together you get 36.

Hope this helps! :)

Answer:  x = -13

=========================

Work Shown:

19 = 38/2

19 & 1/2 = 19 + 1/2

19 & 1/2 = 38/2 + 1/2

19 & 1/2 = (38+1)/2

19 & 1/2 = 39/2

-------

In the original equation, replace the "19 & 1/2" with "39/2" to get

(5/2)x + (1/2)x = 39/2 + (9/2)x

Each term involves a fraction with a denominator of 2. If we multiply both sides by the common denominator, then the fractions will cancel out

For example: 2*(5/2)x = (10/2)x = 5x

So after multiplying both sides by 2, you should have this new equation

5x + 1x = 39 + 9x

--------

Let's solve that latest equation for x

5x + 1x = 39 + 9x

6x = 39 + 9x

6x-9x = 39 + 9x-9x ... subtract 9x from both sides

-3x = 39

-3x/(-3) = 39/(-3) .... divide both sides by -3

x = -13

y = 2x

Step-by-step explanation:

The linear functions are given by:

y = mx+b

To find the slope, we have to find the change in x and y

The change in x is:

[tex]-14-(42) =-14+42 =28\\14+14= 28[/tex]

The change in y is:

[tex]-28-(-84) = -28+84 = 56\\28-(-28) = 28+28 = 56[/tex]

The slope is:

[tex]Slope = \frac{change\ in\ y}{Change\ in\ x}\\=\frac{56}{28}\\= 2[/tex]

Putting slope in equation of linear function

[tex]y =2x+b[/tex]

To find the value of b, we will put any pair of input and output in the slope-intercept form

So, putting (14,28)

[tex]28 = 2(14) + b\\28 = 28+b\\b = 28-28\\b = 0[/tex]

Hence,

the linear equation for function is:

y = 2x

Answer:

14 +(9×x) = y x being the number of pizzas that are not the first one and y is the amount it all cost

Answer:

See explanation below:

Step-by-step explanation:

Here we want to express the number of pizza delivered. Lets try to understand the case.

If we buy one pizza (p1) the cost is 14 because of the delivery plus 9 for the cost of the pizza. So:

p1 = 14 + 9 = 23

If we buy 2 pizzas (p2) we have to pay 14 for the delivery and 9 for each pizza:

p2 = 14 + 9 + 9 = 14 + 2*9 = 32

If 3 pizzas are bought (p3) the reasoning is the same, 14 for the delivery and 9 for each pizza:

p3 = 14 + 9 + 9 + 9 = 14 + 3*9 = 41

Here we can see a pattern: for any amount of pizzas n the cost will be 14 plus n-times 9, the price of a pizza. It is:

pn = 14 + 9*n

But we can separate the last equation in such a way:

pn = 14 + 9*(n-1) + 9 , as 9*(n-1) + 9 = 9*n

But if our general formula it true, the first to terms on the right are the vost of buying n-1 pizzas, so:

pn = pn-1 + 9

We can keep on separating terms as we did to arrive to this form, this is, separating the 9n in  9*(n-2) + 9*2,  9*(n-3) + 9*3, ...,  9*(n-m) + 9*m for any m < n . Here I will keep pn = pn-1 + 9 as the Recursive Formula, but you could use other formulation with, e.g., pn-2, pn-3, etc, using the above recursion.

Now, the explicit formula is such that gives as the value of any amount, finding all the terms of the sequence with those not depending on previous terms (contrary to the recursive). This formula was showed above and is: pn = 14 + 9*n. This is, given any number of pizzas we can find the cost without knowing the cost of previous values.

So, we have:

Recursive: pn = pn-1 + 9

Explicit: pn = 14 + 9*n

Answer:

[tex]6.5 \times 10^{-9}[/tex]

Step-by-step explanation:

The scientific notation of a number is to express the number in the form [tex]x\times 10^{y}[/tex] where x is the base of ten.

So, if we want to express the number 0.0000000065, then we can write it as

[tex]\frac{6.5}{1000000000} = 6.5 \times 10^{-9}[/tex].

So, we can write 0.0000000065 as [tex]65\times 10^{-10}[/tex] or [tex]0.65 \times 10^{-8}[/tex] but those are not the scientific notation.  

Therefore, [tex]6.5 \times 10^{-9}[/tex] is the scientific notation of 0.0000000065. (Answer)

Answer:

12x + 18y

Step-by-step explanation:

Lets first write the quantity "two x plus three y", this means, that we have x and y as unknowns. x is 2 times, so we have 2x; and y is 3 times, so he have 3y:

2x + 3y

Additionally we have that this quantity is six times, what means that it is multiplied by a number 6:

6(2x +3y)

If you like, we can apply the distributive property that means that given any three numbers a, b, c we have that a(b+c)=ab + ac. In our case a is 6, b is 2x and c is 3y. Thus, operating:

6(2x +3y) = 6*2x + 6*3y = 12x + 18y

So, "six times the quantity two x plus three y" is 12x + 18y

The solution on the graph is the coordinate of the point where both lines intersect

Given the equation of two lines expessed as;

y = -3x + 3 and y = 12 x - 4

Since both expressions ara y values, equating both will give;

-3x + 3 = 12x - 4

-3x - 12x = -4 - 3

-15x = -7

x = 7/15

Substitute x = 7/15 into any of the equatons;

y = -3x + 3

y = -3(7/15) + 3

y = -7/5 + 3

y = 8/5

Hence the solution as an ordered pair is (7/15, 8/15)

The solution on the graph is the coordinate of the point where both lines intersect as shown in the graph below;

Step-by-step explanation:

Given that for every 2 apples there are 3 oranges.

How many oranges would be there in a basket of 20 apples?

Since for every couple of apples we have 3 oranges we will calculate how many couples of apples are there in the basket.

Given there are 20 apples. This means that there are [tex]$ \frac{20}{2} $[/tex] = 10 pairs of apples.

Since for one pair we have three oranges, for 10 pairs we would have 3 X 10 = 30 oranges.

Therefore, we can conclude that the number of oranges in the bigger basket would be 30.

Step-by-step explanation:

Answer:

The Value of x= 7.

m∠A= 21°

m∠B= 80°

m∠C= 79°

Step-by-step explanation:

Given:

m∠A = 2x+7

m∠B = 10x+10

m∠C = 8x+23

We need to find the value of x and measures of each angle.

Now by angle sum property which states that sum of all angles of a triangle are 180°.

Hence from above statement we can say in ΔABC;

m∠A+m∠B+m∠C=180

Now substituting the given values in above equation we get;

[tex]2x+7+10x+10+8x+23=180\\2x+10x+8x+7+10+23=180\\20x+40=180\\20x=180-40\\20x=140\\\\x=\frac{140}{20} =7[/tex]

Hence value of x is 7.

Substituting the value of x in all angles we get;

m∠A=[tex]2x+7=2\times7+7=14+7=21\°[/tex]

m∠B=[tex]10x+10=10\times7+10=70+10=80\°[/tex]

m∠C=[tex]8x+23= 8\times7 +23 = 56+23=79\°[/tex]

Final answer:

To find the value of x and the measure of each angle in triangle ABC, set up an equation using the given angle measures. Solve for x and substitute it back in to find the measures of each angle. Then : m<A = 2(7) + 7 = 21 degrees

m<B = 10(7) + 10 = 80 degrees

m<C = 8(7) + 23 = 79 degrees

Explanation:

To find the value of x and the measure of each angle in triangle ABC, we need to set up an equation using the given angle measures. Since the sum of the angles in a triangle is 180 degrees, we can write the equation as:

m<A + m<B + m<C = 180

Substituting the given angle measures, we have:

(2x + 7) + (10x + 10) + (8x + 23) = 180

Simplifying the equation:

20x + 40 = 180

Subtracting 40 from both sides:

20x = 140

Dividing both sides by 20:

x = 7

Now that we know the value of x, we can find the measure of each angle by substituting x into the respective expressions:

m<A = 2(7) + 7 = 21 degrees

m<B = 10(7) + 10 = 80 degrees

m<C = 8(7) + 23 = 79 degrees

To minimize production cost, we need to find the dimensions of the package that will satisfy the volume equation and minimize the cost equation. Taking the partial derivatives of the cost equation with respect to the variables 'r' and 'h', and setting them equal to zero, we can find the critical points. Solving these equations, we find that the dimensions for the package that will minimize production cost are a height of 7 cm and a radius of 2.5 cm.

To find the dimensions of the package that will minimize production cost, we need to consider the cost of the sides and bottom made of styrofoam and the cost of the top made of glued paper. Let's denote the radius of the base of the cylinder as 'r' and the height of the cylinder as 'h'.

The volume of a cylinder is given by the formula V = πr²h. We know that the volume of the package needs to be 350 cubic centimeters, so we can write the equation as πr²h = 350.

The cost of the sides and bottom of the container is given by the formula C1 = 0.03 * (2πrh + πr²), and the cost of the top is given by the formula C2 = 0.08 * πr².

To minimize the cost, we need to find the values of 'r' and 'h' that satisfy the volume equation and minimize the cost equation.

Since this is a calculus problem, we will differentiate the cost equation with respect to 'r' and 'h', and set the derivatives equal to zero to find the critical points.

Taking the partial derivatives of C1 and C2 with respect to 'r' and 'h', we get:

Solving these equations, we find that h = 7 cm and r = 2.5 cm. Therefore, the dimensions for the package that will minimize production cost are a height of 7 cm and a radius of 2.5 cm.
