2(x + 5) = 30 what does x equal?​

Answer:

angle: 71

x = -3

Step-by-step explanation:

step 1: 180-(55+54) = 71

step 2: x+74=71 (subtract 74 from both sides)

step 3: x=-3

step 4: -3+74=71

Answer:

x = 144

Step-by-step explanation:

3/4x + 24 = x - 12

3/4x - x = -12 - 24

3/4x - 4/4x = -36

-1/4x = -36

x = -36/-1/4

x = 144

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.

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

Step-by-step explanation:

The statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.

Correlation coefficient is used to calculate how strong the relationship is between the two variables.

When there is a statistical relationship between two or more variables, then they are said to be in correlation.

Types of correlation-

The graph shows a volume of ice cubes versus temperature in degrees Celsius.

For a perfect correlation, -1 or +1 values is ideal. Here, some relation can be seen in a negative straight line, which suggest that the correlation coefficient is not close to zero.

Both volume and temperature has strong correlation for linear line where, temperature is the explanatory variable.

Thus, the statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.

Answer:

Area = 113.01 m²

Step-by-step explanation:

From the picture attached,

Area of the quadrilateral ABCD = Area of triangle ABC+ Area of triangle ACD

Construction to be done → Draw a perpendicular from a point A to the opposite side CD

Area of Δ ABC = [tex]\frac{1}{2}(AB)(BC)[/tex]

                         = [tex]\frac{1}{2}(12)(10)[/tex]

                         = 60 m²

Area of triangle ACD = [tex]\frac{1}{2}(AE)(CD)[/tex]

From ΔAEC,

sin(29°) = [tex]\frac{AE}{AC}[/tex]

AC = [tex]\sqrt{(12)^2+(10)^2}[/tex] [By Pythagoras theorem]

AC = [tex]\sqrt{244}[/tex]

AC = 15.62 m

Therefore, AE = 15.62sin(29)

                        = 7.57 m

Area of ΔACD = [tex]\frac{1}{2}(7.57)(14)[/tex]

                        = 53.01 m²                                

Area of ABCD = 60 + 53.01

                        = 113.01 m²

25 divide by 5 = 5  60 divide by 12 =5

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]

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

Answer:

y = 2/5x + 18.

Step-by-step explanation:

The line will have the same slope of 2/5.

Using the point-slope form of a line:

y - 12 = 2/5(x - -15)

y - 12 = 2/5(x + 15)

y = 2/5x + 6 + 12

y = 2/5x + 18.

Answer:

y  = (2/5)*x + 18

Step-by-step explanation:

Because the line is parallel to the line y = 2/5 x + 17, the slope of the new line has to be the same as well. So far, we have y = (2/5)*x .

Now what we can do is plug in -15 for x and see what we get for y. Because we get -6, we need 18 more to make it 12. Because of that, the y-intercept is 18 to make the equation of the line y  = (2/5)*x + 18.
