Answer:

See below.

Step-by-step explanation:

1)

So we have the equation:

[tex]2x+3y=1470[/tex]

To change into the slope-intercept form, we need to isolate the y-variable. Thus, subtract 2x from both sides:

[tex](2x+3y)-2x=(1470)-2x[/tex]

The left side cancels:

[tex]3y=1470-2x[/tex]

Now, divide both sides by 3. The left side cancels:

[tex](3y)/3=(-2x+1470)/3\\y=-\frac{2}{3} x+490[/tex]

The slope-intercept form is:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

Thus, the slope is -2/3 and the y-intercept is 490.

2)

So, since we already know the y-intercept is 490, plot a point at (0,490).

The slope is too small to use. Thus, multiply the fraction by 100. It is now (-200/300). This means that we move down 200 for every 300 (recall that the slope means rise over run. Thus, we move down 200 for every 300 to the right). Thus, another possible point would be (0+300,490-200) or (300,290). Plot that. Then, connect them.

3)

To write in in function notation, simply substitute the y-variable for the function notation. Our independent variable here is x so we'll use that.

[tex]y=-\frac{2}{3}x+490\\ f(x)=-\frac{2}{3}x+490[/tex]

This means that for every x sandwiches made, there is f(x) wraps made for the total sum to be $1,470.

For example, if 105 sandwiches were made, then f(105)=-2/3(105)+490=420 wraps were made for the total profit to be $1,470.

4)

Please refer to the attached graph.

5)

First, since the total profit has now increased, the graph above and to the right of the old graph. This is because Sal needs to sell more sandwiches and wraps. Likewise, because of this, the x- and y-intercepts will also be different. Nevertheless, if converted into the slope-intercept equation, the slope will remain the same.

Answer:

-6

Step-by-step explanation:

We use PEMDAS to solve this,

so P stands for parentheses, so that's where we start.

We first, square the innermost parentheses with the exponent which is the E in PEMDAS, then then the outer parentheses

-12/3*(-8+16-6)+2

-12/3*(2)+2

Now we divide as in Division in PEMDAS.

-4*2+2

Now we multiply as in Multiplication in PEMDAS.

-8+2

Now we add as in A for Addition

-6

In PEMDAS, Multiplication doesn't always come before division, and same for addition and subtraction.

Answer:

Rs 253.13

Step-by-step explanation:

The item cost him x.

Selling at a profit of 20% means he sold it for 1.2x.

Selling at a loss of 12% means that he sold it for 0.88x.

1.2x - 81 = 0.88x

1.2x - 0.88x = 81

0.32x = 81

x = 253.13

Answer:

The age of brothers are 4 years and 2 years respectively.

Step-by-step explanation:

We are given that the ages of two brothers have a ratio of 2 to 1. When 4 years have passed, the ratio of their ages will be 8 to 6.

Let the age of the first brother be 'x years' and the age of the second brother be 'y years'.

So, according to the question;

                                      [tex]\frac{x}{y} =\frac{2}{1}[/tex]  

                                      [tex]x=2y[/tex]  -------------- [equation 1]

                                       [tex]\frac{x+4}{y+4}=\frac{8}{6}[/tex]

                               [tex]6({x+4})=8}(y+4)[/tex]

                               [tex]6x+24=8y+32[/tex]

                               [tex]6(2y)+24=8y+32[/tex]

                               [tex]12y-8y=32-24[/tex]

                                    [tex]4y=8[/tex]

                                     [tex]y=\frac{8}{4}[/tex] = 2 years

Putting the value of y in equation 1 we get;

                                     x = 2y

                                      x = [tex]2 \times 2[/tex] = 4 years

Hence, the age of brothers are 4 years and 2 years respectively.

Answer:

P=25 q= -31

Step-by-step explanati

The value of p and q​ are 32 and 24. The relationship will be as p/q = 8/6.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

The cost of an electrical gadget and the cost of a plumbing material were in the ratio 8:6 last year ,this year each cost was reduced by GHÇ 4.00 and their ratio changed to 7:5.

Make p the subject

p = 8q/6 ........equation 1

The year the price was reduced by 4

p - 4/q - 4 = 7/5

Cross multiplication;

5(p-4) = 7(q-4)

5p-20 = 7q-28

5p - 7q = -8 .......equation 2

Subtract 8q/6 for p in equation 1

5(8q/6) - 7q = -8

Multiply through by 6

40q - 42q = -48

-2q = -48

q = 24

Subtract 24 for q in equation 1

p = 8(24)/6

p = 192/6

p = 32

Therefore, the value of p and q​ are 32 and 24. The relationship will be as p/q = 8/6.

Step-by-step explanation:

Answer:

[tex]x = 10[/tex]. In other words, there number of girls is [tex]10[/tex].

Step-by-step explanation:

The average of a number of measurements is equal to the sum of these measurements over the number of measurements.

[tex]\displaystyle \text{Average} = \frac{\text{Sum of measurements}}{\text{Number of measurements}}[/tex].

Rewrite to obtain:

[tex]\begin{aligned}& \text{Sum of measurements}= (\text{Number of measurements}) \times (\text{Average}) \end{aligned}[/tex].

For this question:

[tex]\begin{aligned}& \text{Sum of heights of boys} \\ &= (\text{Number of boys}) \times (\text{Average height of boys}) \\ &= 15 \times 125 = 1875\end{aligned}[/tex].

[tex]\begin{aligned}& \text{Sum of heights of girls} \\ &= (\text{Number of girls}) \times (\text{Average height of girls}) \\ &= x \times 120 = 120\, x\end{aligned}[/tex].

Therefore:

[tex]\begin{aligned}& \text{Sum of boys and girls} \\ &= \text{Sum of heights of boys} + \text{Sum of heights of girls}\\ &= 1875 + 120\, x\end{aligned}[/tex].

On the other hand, there are [tex](15 + x)[/tex] boys and girls in total. Using the formula for average:

[tex]\begin{aligned}& \text{Average height of boys and girls} \\ &= \frac{\text{Sum of heights of boys and girls}}{\text{Number of boys and girls}} \\ &= \frac{1875 + 120\, x}{15 + x}\end{aligned}[/tex].

From the question, this average should be equal to [tex]123[/tex]. In other words:

[tex]\displaystyle \frac{1875 + 120\, x}{15 + x} = 123[/tex].

Solve this equation for [tex]x[/tex] to obtain:

[tex]1875 + 120\, x= 123\, (15 + x)[/tex].

[tex](123 - 120)\, x = 1875 - 123 \times 15[/tex].

[tex]x = 10[/tex].

In other words, the number of girls here is [tex]10[/tex].

Answer to the 1st part: [tex]6x^2+12xh+6h^2-2x-2h+1[/tex]

Answer to the 2nd part: [tex]12x+6h-2[/tex]

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

Work Shown:

Replace every x with (x+h). Expand and simplify

[tex]f(x) = 6x^2-2x+1\\\\f(x+h) = 6(x+h)^2-2(x+h)+1\\\\f(x+h) = 6(x^2+2xh+h^2)-2(x+h)+1\\\\f(x+h) = 6x^2+12xh+6h^2-2x-2h+1\\\\[/tex]

----------------------------

Subtract off f(x), then divide everything over h. Simplify.

[tex]f(x+h) = 6x^2+12xh+6h^2-2x-2h+1\\\\f(x+h)-f(x) = 6x^2+12xh+6h^2-2x-2h+1-(6x^2-2x+1)\\\\f(x+h)-f(x) = 6x^2+12xh+6h^2-2x-2h+1-6x^2+2x-1\\\\f(x+h)-f(x) = 12xh+6h^2-2h\\\\\frac{f(x+h)-f(x)}{h} = \frac{12xh+6h^2-2h}{h}\\\\\frac{f(x+h)-f(x)}{h} = \frac{h(12x+6h-2)}{h}\\\\\frac{f(x+h)-f(x)}{h} = 12x+6h-2\\\\[/tex]

The value of Function,  [tex]f (x + h) = 6x^2 + 6 h^2 + 12 x h - 2x -2h + 1[/tex]

And, The value of  [tex]\frac{f (x + h)- f(x)}{h} = 12 x + 6h -2[/tex].

Here, the function is given as,

[tex]f (x) = 6x^{2} -2x + 1[/tex]

What is function?

A function from a set X to a set Y assigns to each element of X exactly one element of Y.

Now,

Replace every x with (x + h) and expand it,

   [tex]f (x) = 6x^{2} -2x + 1\\f (x+h) = 6(x+h)^{2} -2(x+h) + 1\\f (x+h) = 6 (x^{2} +h^{2} + 2xh) - 2x -2h +1\\f (x+h) = 6x^{2} +6h^{2} +12xh -2x-2h+1\\[/tex]

And,

[tex]f (x+h) - f(x) = ( 6x^{2} +6h^{2} +12xh -2x-2h+1) - (6x^{2} -2x+1)\\\frac{f (x+h) -f (x)}{h} =\frac{ ( 6x^{2} +6h^{2} +12xh -2x-2h+1) - (6x^{2} -2x+1)\\}{h} \\\frac{f (x+h) -f (x)}{h} =\frac{ 6x^{2} +6h^{2} +12xh -2x-2h+1 -6x^{2} +2x-1\\}{h} \\\\\frac{f (x+h) -f (x)}{h} =\frac{12xh +6h^{2}-2h }{h} \\\frac{f (x+h) -f (x)}{h} = 12x + 6h -2[/tex]

Hence,

The value of function [tex]f (x + h) = 6x^2 + 6 h^2 + 12 x h - 2x -2h + 1[/tex]

Now, subtract 8 from both sides:

[tex]8-8-14b\geq 27-8\\-14b\geq 19[/tex]

Now, divide both sides by -14 and flip the inequality sign since we are dividing by a negative:
