Answer:
m=2
Step-by-step explanation:
We are given a line y=mx-7 and the point lying on the given line is (3,-1) in the standard {x,y} coordinate plane.
Therefore, substituting the values of x=3 and y=-1 in the given line, we have,
⇒
⇒
⇒
⇒
⇒
Hence,the value of m will be equal to two.
Answer:
B. about 225
Step-by-step explanation:
Answer:
a) 69
b) 69
Step-by-step explanation:
Since 69 and x are alternate interior angles, they must be congruent, and therefore x must equal 69 degrees. Similarly, since y and 111 must be supplementary, it must also be equal to 180-111=69 degrees. Hope this helps!
Answer:
(C) (4,0)
Step-by-step explanation:
Given the graph which represents the system of equations:
3x+4y=12; and
2x-y=8.
- One line passes through (0, 3) and (4, 0).
- The other line passes through (2, -4) and (4, 0).
From the points given, both lines pass through the point (4,0).
Therefore, the ordered pair which is a solution to the system of equations is (4,0).
The correct option is C.
Here x is 7/4 so answer is 16
