Answer:
y=-5x+35
Step-by-step explanation:
The equation for a line in slope intercept form is y=mx+b, where m is the slope of the line and b is the y intercept, or where the line meets the y axis.
First, we should calculate the slope of the line. The slope of any line is rise over run. We can select any two points- I will select (6,5) and (4, 15).
We see that the rise is 10 units, because 15-5=10, and the run is -2 units, because 4-6=-2. We have rise over run which is 10/-2, or -5.
So, we find that the m value is equal to -5.
The y intercept is easier to find, it is just where the line meets the y axis. The lines meets the y axis at the point (0,35) so the y intercept is 35.
Thus we have the equation of the line is y=-5x+35.
Hope this helps!
Using guess and check, the answer is (7x+2)(x-1)
Answer:
EACH central angle = 360 / number of sides
number of sides = 360 / each central angle
number of sides = 360 / 40
number of sides = 9
Answer:
D. 
Step-by-step explanation:
Cross cancel common factor ; 6
Three is the co-efficient of x
26.2 / 2 = 189.3 / x
<span>Numerator = distance </span>
<span>Denominator = time </span>
<span>126.2x = (2)(189.3) </span>
<span>126.2x = 378.6 </span>
<span>x = 3 </span>
<span>It will take her 3 hours.
I really hope this helps!
