Answer:
y = 2x - 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (6, 7)
m = (7 + 9) / (6 + 2) = 16/8 = 2
y = 2x + c ← is the partial equation
to find c use either of the 2 points
using (6, 7), then
7 = 12 + c ⇒ c = 7 - 12 = - 5
y = 2x - 5 ← equation in slope-intercept form
Arrange the cards into three pairs with the same total.
Note: Please write each pair on separate lines and
use the word 'and' between the numbers (eg. 7 and -3).
Answer:
See explanation
Step-by-step explanation:
The first pair is (-4 and 8)
Because if we add those two values, i. e., 8 + (-4), we will get 4.
Again, the second pair is (-2 and 6). In that case, if we also add those two values, that is, 6 + (-2), we will get 4.
Finally, the third pair is (-1 and 5). Again, we will add the two values. 5 + (-1) = 4.
In each case, we can see that the addition of each pair is 4.Therefore, the total is similar in each pair after arranging the cards.
B. The set of all real numbers.
C. The set of all real numbers greater than or equal to zero.
D. The set of all integers.
Answer:
a matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. For example, the dimension of the matrix below is 2 × 3, because there are two rows and three columns: Provided that they have the same size, two matrices can be added or subtracted element by element.
