Mixed number: 3 8/100
improper fraction: 308/100
Answer:
Step-by-step explanation:
x^2 + 3x - 1 + 3x
x^2 + 6x - 1 is the solution
Answer:
<h2>149 times.</h2>
Step-by-step explanation:
Let n be the number we are looking for.
The we have to solve this equation:
1999 - 7n = 1701 - 5n
⇔ 1999 - 1701 = 7n - 5n
⇔ 298 = 2 n
⇔ n = 298/2
⇔ n = 149
<u><em>Verification</em></u> :
1 999 - 7×149 = 956
1 701 - 5×149 = 956
Answer:
x-int:(-2,0)(-4,0) . y-int:(0,8)
Step-by-step explanation:
y = x2+6x+8 and y = (x+2)(x+4)
x-int:
x+2=0
x= -2
(-2,0)
x-int:
x+4=0
x=-4
(-4,0)
y-int: plug 0 for x
y=(0+2)(0+4)
y=8
(0,8)
Check out the attached image below. I've marked two red points on the line such that the points have whole number coordinates. This way I could compute the slope of this line to be -2/5
We move down 2 units (rise of -2) as shown by the blue arrows. Afterward, we move 5 units to the right as shown by the green arrows (which is the run). This gets us from the left red point to the right red point.
rise = -2, run = 5
slope = rise/run = -2/5
the original line shown has a slope of -2/5
----------------------------
Next we do two things to get the perpendicular slope.
Flip the fraction: -2/5 becomes -5/2
Flip the sign: -5/2 becomes +5/2 or simply 5/2
----------------------------
Final Answer: 5/2
