Answer:
A. j > 11
B. x ≥ 8
Step-by-step explanation:
For A if 7j is greater than 77, then j has to be more than 11. 7 x 11= 77.
For B x has to be greater or equal to 17, and 8+9 is equal to 17.
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, and in this case:
-m/4=-1
-m=-4
m=4, so the slope of the perpendicular line is 4 so we have thus far:
y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"
3=4(-4)+b
3=-16+b
19=b, so our line is:
y=4x+19
Answer:
5/8+1/2=9/8 or 1 1/8
Step-by-step explanation:
1/2 x 4 (top and bottom)= 4/8
5/8 + 4/8 = 9/8
Answer:
23 Seconds
The roach is going 2 feet per second so you can split the amount of feet in half because he will go the same distance 2 times as fast.
2x + y = 5
Put the coordinates of the points to the equation and check it:
A. 5 - not make sense
B. (1, 2) - x = 1, y = 2
2(1) + 2 = 2 + 2 = 4 ≠ 5 NOT
C. (2, -1) - x = 2, y = -1
2(2) + (-1) = 4 - 1 = 2 ≠ 5 NOT
D. (3, -1) - x = 3, y = -1
2(3) + (-1) = 6 - 1 = 5 YES
<h3>Answer: D. (3, -1).</h3>
