Sure you do !
I'll tell you what it is, and why, and you'll slap your forehead
and call yourself names.
The 'standard' form of an equation that shows the slope and intercept is
y = (slope) x + (intercept)
<em><u>What if the slope is zero</u> ?</em>
Then the equation is y = (0) x + intercept
or
y = intercept.
Does that look anything like y = -3 ?
Answer:
Step-by-step explanation:
There is not enough information to solve for x.
All we know is that the lines are parallel so the two inner angles will have the same angle measure.
And the angle measures are probably 90 degrees if the transversal (the line cutting through the two parallel lines) is perpendicular to the parallel lines

Answer:
x=amount invested at 7%
2x=amount invested at 8%
3x=amount invested at 9%
interest=principal*rate*time (time=1 year)
$150=0.07x+0.08*2x+0.09*3x
$150=0.07x+0.16x+0.27x
$150=0.50x
$1500=5x
x=$300 invested at 7%
2x=$600 invested at 8%
3x=$900 invested at 9%

Answer:
± 27.33 ft
Step-by-step explanation:
For the given problem, we can estimate the initial and final coordinates of the line of the ball path as (-40,-50) and (0,0). Therefore, the slope is:
(-50-0)/(-40-0) = 50/40 = 1.25
Similarly, we can estimate the slope of a perpendicular line to the line of the ball path as: -1*(1/1.25) = -0.8.
Therefore, using (0,0) and the slope -0.8, the equation of the perpendicular line is: -0.8 = (y-0)/(x-0);
-0.8 = y/x
y = -0.8x
Furthermore, we are given the circle radius as 35 ft and we can use the distance formula to find the two points 35 ft far from the origin:
35^2 = x^2 + y^2
y = -0.8x
35^2 = x^2 + (-0.8x)^2
1225 = (x^2 + 0.64x^2)
1225 = 1.64x^2
x^2 = 1225/1.64 = 746.95
x = sqrt(746.95) = ± 27.33 ft
