Answer:
B) y = 2x - 3
Step-by-step explanation:
We can determine which equation the line follows by checking the y-intercepts of each equation. The line passes through the point (0, -3) - this is the <em>y-intercept</em> of the line. The y-intercept in an equation is the single value after the slope. So, for example, in a line y = mx + b, b is the y-intercept.
For A, our y-intercept is (0, 2). For B, our y-intercept is (0, -3). For C, our y-intercept is (0, 3). For D, our y-intercept is (0, -2). So which one matches our line? It would be B, since both have a y-intercept of (0, -3).
So, that's our answer. If you need more help, let me know! :)
Answer:
x=30, y=90
Step-by-step explanation:
y+x and y-x are supplementary angles. They must add to 180 degrees
y+x+y-x = 180
Combine like terms
2y = 180
Divide by 2
2y/2 = 180/2
y= 90
y+x and 2x are supplementary angles. They must add to 180 degrees
y+x+2x = 180
y+3x =180
We know y =90
90+3x=180
Subtract 90 from each side
90-90 +3x = 180-90
3x= 90
Divide by 3
3x/3 = 90/3
x = 30
We are asked to perform factorization in the given expression y2 + 10z - 10y -yz. The solution to this problem is shown below:
y2 + 10z - 10y - yz , we need to separate term such as below:
(y - 10) (y - z)
Perform checking:
(y-10) (y- z) = y2 -yz -10y +10z which the same in the given expression in the problem
Therefore, the answer is (y-10)(y-z).
Answer:
|-6 -(-3)| = 3
Step-by-step explanation:
The two points lie on a horizontal line, so the distance between them is the (positive) difference of their x-coordinates:
|B - A| = |-6 -(-3)| = |-6+3| = |-3| = 3
The distance between these points is 3 units.
