In the expression, 2y2 + 4x – y + x2 +8, what is the coefficient
of x2 ?
A- 8
B- 2
C- 1
D- 4

Step-by-step explanation:

for 12

Perimeter (P)

= 2( L + B)

= 2 ( 500 + 300)

=2 * 800

= 1600 cm

For 13

Area

= L * B

= 500 * 300

= 150000 cm²

Step-by-step explanation:

Since Promethean board is rectangle in shape,

So Given,

Dimensions of that board = 500 cm by 300 cm

Hence, Perimeter of the board = 2(l+b)

= 2(500cm + 300cm) = 2 × 800cm

= 1600cm (Ans)(i)

Therefore, area of that board = l × b

= 500cm × 300cm

[tex] = 150000 {cm}^{2} (ans)(ii)[/tex]

Answer:

a= 12

b=-2

Step-by-step explanation:

12 x -2 = -24

12 - (-2) = 14

12 + (-2) = 10

The two integers are 12 and -2.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Let x and y be the two integers.

So it is given that,

Product of two integers =  – 24

⇒ xy = - 24   ....(i)

The difference between the two integers =  14

⇒ x - y = 14  ...(ii)

The sum of the two integers = 10

⇒ x + y = 10     ....(iii)

Now adding equation (ii) and (iii) we get,

2x = 24

⇒ x = 12

Putting the value of x in equation (i) we get,

12y = - 24

⇒ y = - 2

So the required integers are 12 and - 2.

Answer:

-3s^2+16s-7

Step-by-step explanation:

-3s(s - 10) + 7(-2s -1)​ --> (-3s^2+30s)+(-14s-7) ---> -3s^2+16s-7

DO multiplication them convert like terms

Answer:

-3s² + 16s - 7

Step-by-step explanation:

Remember to follow FOIL. FOIL stands for (First, Outside, Inside, Last).

First, distribute -3s to s and -10, and 7 to -2s and -1:

-3s(s - 10) = -3s² + 30s

7(-2s - 1) = -14s - 7

Next, combine like terms:

-3s² + 30s - 14s - 7

-3s² + (30s - 14s) - 7

-3s² + 16s - 7

-3s² + 16s - 7 is your answer.

Answer:

X=-1

Step-by-step explanation:

The correct equation could represent a vertical asymptote of the graph of the function is,

⇒ x = -1

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Now, According to the given table, we see that for x = -1, the function is not defined, that means that the rational function has a restriction there, and such restriction is shown as an asymptote in the graph of the function.

So, basically, we could say that the given rational function has one asymptote and it's at x = -1, which is a vertical asymptote, because all forms like x = k, are vertical lines, that is, they are parallel to the vertical axis.

Therefore, The correct equation could represent a vertical asymptote of the graph of the function is,

⇒ x = -1

Can u plz mark me branliest plz.

Answer:

p = 50

Step-by-step explanation:

[tex]\frac{1}{2} *p+75=100\\[/tex]

Combine like terms into a single fraction:

[tex]\frac{1}{2} p+75=100[/tex]

[tex]\frac{1p}{2} +75=100[/tex]

Multiply by 1:

[tex]\frac{1p}{2}+75=100[/tex]

[tex]\frac{p}{2} +75=100[/tex]

Subtract 75 from both sides of the equation:

[tex]\frac{p}{2} +75=100[/tex]

[tex]\frac{p}{2} +75-75=100-75[/tex]

Simplify:

Subtract the numbers:

[tex]\frac{p}{2} +75-75=100-75[/tex]

[tex]\frac{p}{2} =100-75[/tex]

Subtract the numbers:

[tex]\frac{p}{2} =100-75[/tex]

[tex]\frac{p}{2} =25[/tex]

Multiply all terms by the same value to eliminate fraction denominators:

[tex]\frac{p}{2} =25[/tex]

[tex]2*\frac{p}{2} =2*25[/tex]

Simplify:

[tex]2*\frac{p}{2} =2*25[/tex]

[tex]p=2*25[/tex]

Multiply the numbers:

[tex]p=2*25[/tex]

[tex]p=50[/tex]

3) 2[tex]x^{2}[/tex] + 3x - 1

Step-by-step explanation:

A quadratic expression is an expression involving a squared term

It can be written as y = a[tex]x^{2}[/tex] + bx + c, where a ≠ 0

// note that here b and c can be equal to 0

1) 6[tex]x^{4}[/tex] - 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a quartic function, since the unknown variable x in forth degree. It can be written as y = a[tex]x^{4}[/tex] +b[tex]x^{3}[/tex] +c[tex]x^{2}[/tex] + dx + e, where a before [tex]x^{4}[/tex] ≠ 0

2) 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a cubic function, since the unknown variable x in third degree.

3) 2[tex]x^{2}[/tex] + 3x - 1 is correct

4) 3x - 1 is incorrect because there is no squared term. You could also say that here a = 0 and write it as y = 0 * [tex]x^{2}[/tex]  + 3x - 1. It is also called a linear function because if you'd draw a graph, it would be a line

Step-by-step explanation:

Given g(x) then g(x) + c is a vertical translation of g(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Thus g(x) is the graph of f(x) translated 5 units up
