Step-by-step explanation:
Tangent Chord Angle = 1/2Intercepted Arc
? = 1/2(140)
? = 70
Answer:
See attachment for graph
Or
The slope intercept form is 
Step-by-step explanation:
Assuming you want to graph the straight line given in point-slope form as

Then we need at least two points on this line
When we compare to the point-slope formula
then we obtain (-5,-2) as a point on this line so we plot it.
When x=0, y=4(0+5)-2=18 so we plot (0,18)
We then draw a straight line through as shown in the attachment.
On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:



A. Youre getting anyone willing to answer the survey, most of them might be in a rush so maybe they’ll decline so i think A is the safesy
This should give you all you need to know
Rearrange the equation by writing
x² + x - 90 = 0
x² + x = 90
x² + x + 1/4 = 90 + 1/4
Recall that (a + b)² = a² + 2ab + b². Then
x² + 2 • x/2 + (1/2)² = 361/4
(x + 1/2)² = 361/4
x + 1/2 = ± √(361/4)
x = -1/2 ± 19/2
x = 9 or x = -10
