9. Answer: x=4
Slope formula is y2-y1/ x2-x1. The slope will become undefined if the denominator, which is x, has a value of zero. That means the graph function would look like x=....
If the line passes point (4,3) equation of the line would be x=4
10. Answer: y=5
Slope formula is y2-y1/ x2-x1. The slope will become zero if the numerator, which is y, has a value of zero. The function would look like y=.....
The equation of the line that pass point (2,5) would be y=5
11. Answer: y=6
A line that parallel with x-axis would be a line with zero slopes and the function would be y=....
If the line passed through (1,6) the equation of the line would be y=6
12. Answer: x=-2
A line that parallel with y-axis would be a line with undefined slopes and the function would be x=....
If the line passed through (-2,4) the equation of the line would be x=-2
13. Answer: y=40
If y varies directly as x, the ratio of x:y would be kept same. It means, the ratio of y1/x1 will be equal to y2/x2. The coordinate is :
x1,y1= (5,10)
x2,y2= (20, ?)
The y when x=20 would be:
y1/x1=y2/x2
10/5= y2/20
y2= 2*20= 40
14. Answer: y=24
Same as above, if y varies directly as x, the ratio of x:y would be kept same. It means, the ratio of y1/x1 will be equal to y2/x2. The coordinate is :
x1,y1= (10,8)
x2,y2= (30, ?)
The y when x=30 would be:
y1/x1=y2/x2
8/10= y2/30
y2= 0.8*30= 24
15. Answer: x=60
If y varies directly as x, the ratio of x:y would be kept same. It means, the ratio of y1/x1 will be equal to y2/x2. Be careful because this problem is asking for x, not the y variable. The coordinate is :
x1,y1= (20,5)
x2,y2= (x2, 15)
The x2 when y=15 would be:
y1/x1=y2/x2
5/20= 15/x2
x2= 15 /0.25 = 60
(4/9)(x + 13) = 8
multiply both sides by (9/4)
(9/4)(4/9)(x + 13) = 8(9/4)
x + 13 = 8
subtract 13 from both sides
x = -5
The correct answer that would complete the given statement above would be 59. The measurement of 0.059 seconds is equal to 59 milliseconds. To convert this, you need to know that in every 1 second, there are 1000 milliseconds. And for 1 millisecond, there is 0.001 second.
Answer:
a^2-3ab+2b^2
Step-by-step explanation:
(a-2b)(a-b)
a^2-2ab-ab+2b^2
a^2-3ab+2b^2
