X=-2; undefined slope means that the line is vertical, and the question states that the x-intercept was negative 2.
Alan bowls one game, which consists of 10 frames. The number of pins he knocked down in each frame is 5, 6, 7, 5, 7, 9, 2, 4, 8,

Alan shoud use mean and range, mean is where you add all of the numbers up and divide by how many numbers there are, and range where you take the highest number and subtract it by the lowest number. This way he will find the greatest and least number of pins he knocked down
A) domain -1 to 1.
Range -pi/2 to pi/2 radians or -90 to 90 degree.
b) domain -1 to 1.
Range 0 to pi radians or 0 to 180 degrees.
c) domain is all real numbers.
Range -pi/2 to pi/2 radians or -90 to 90 degree.
Answer: y = 2 or 7
Step-by-step explanation:Copy and open the bracket
2y² + 5y +63 = (y + 7 )²
expand the right hand expression (y + 7 )², which now becomes
y² + 14y +49 , now equate the 2 together and arrange it into a quadratic structure
2y² + 5y +63 = y² + 14y + 49
2y² - y² + 5y - 14y +63 - 49 = 0
y² -9y + 14 = 0
Now, factorize the expression using grouping or any method
y² -7y - 2y + 14 = 0, considering two factors, when multiplied together gives +14, and when added together gives - 9
Considering the common factors ,it now becomes
y( y - 7) -2(y - 7) =0
(y - 2)(y - 7) = 0
To find the root of y,
when y - 7 = 0
y = 7, and when y- 2 =0, y = 2
Therefore, the solution of the equation is
y = 2, or 7.
Answer:
the dimensions will be 2 x 1
Option C is correct option.
Step-by-step explanation:
We need to determine the dimensions of this matrix ![\left[\begin{array}{c}2&\sqrt{5} \end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D2%26%5Csqrt%7B5%7D%20%5Cend%7Barray%7D%5Cright%5D)
The dimensions consists of rows and columns in the form. Rows x Columns
In the given matrix the rows are: 2
The columns are: 1
So, the dimensions will be 2 x 1
Option C is correct option.
