Answer:
The equation of the line is:
Step-by-step explanation:
Given the points
Finding the slope between the points
We know the slope-intercept form of the line equation
where m is the slope and b is the slope-intercept form
substituting the value m=2 and the point (-2, -5) to find the b-intercept
-5 = 2(-2) + b
b = -5+4
b = -1
Now, substituting m=2 and b=-1 in the slope-intercept form to get the equation of a line
y=mx+b
y=2x+(-1)
y=2x-1
Thus, the equation of the line is:

Answer: 552 cubic meters
Step-by-step explanation: You want to find the volume. To do this, multiply each number with each other. 7 times 9 times 8 is 504 and 3 times 8 times 2 is 48. Then, add the two products. 504 plus 48 is 552.
Answer:
k=-10
Step-by-step explanation:
-9+k/10=-10
add 9 to both sides
k/10=-1
then multiply 10 by both sides
k = -10

Answer:
C
Step-by-step explanation:
The inverse of a matrix is the transpose of the cofactor matrix, divided by the determinant. The determinant is (4)(3) -(1)(-5) = 17, eliminating choice B.
In a 2×2 matrix, the transpose of the cofactor matrix swaps the diagonal elements, and negates the off-diagonal elements. That is, the transpose of the cofactor matrix will look like the matrix of B. When that is divided by 17, you get the matrix of answer choice C.
