Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.
Step-by-step explanation:
A slope with a greater absolute value indicates a steeper line. The direction of a line is either increasing, decreasing, horizontal or vertical.

The graph shows a volume of ice cubes versus temperature in degrees celsius. Which of the statements is false?
A. The correlation coefficient is close to zero.
B. Temperature is strongly correlated to the volume of ice cubes.
C. Temperature is the explanatory variable.
D. The data show a negative linear relationship.
The statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.
What is the correlation coefficient?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-
Positive correlation coefficient- When the value of correlation coefficient is positive, then the value of one variable increases with increase in other variable.Negative correlation coefficient- When the value of correlation coefficient is negative, then the value of one variable decreases with increase in other variable.
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.

g(x)=f(x)+5 what's the transformation?
Answer:
see explanation
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

Find the equation of a line which is parallel to y= 2/5 x + 17 and passes through (-15,12)
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.

What is the value of x in the equation 3/4 x + 24 = x − 12 ?
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:
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

Answer:
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

The product of
two integers is – 24. The difference
between the two integers is 14. The sum of
the two integers is 10. What are the two
integers?
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.
What are simultaneous equation?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.

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
