- Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.
So starting with the y-intercept, the easiest method to find it is to convert this standard form equation to slope-intercept form. Firstly, add 5x to both sides:
Next, divide both sides by -4 and your slope-intercept form is 
Looking at this slope-intercept form, <u>the y-intercept is (0, -5/2).</u>
Now to find the x-intercept, just set the y-variable to zero and solve:
<u>Our x-intercept is (-2,0).</u>
Answer:
hour hand = 7.5 x 2 for the diameter. C = 2(pi)(15) = approx. 94 centimeters. Minute hand = 9.5 x 2 = 19, C = 2(pi)(19) = approx. 119 centimeters
Step-by-step explanation:
Answer:
37º
Step-by-step explanation:
∠ABC (Interior) = 360º - 5x
Sum of interior angles in a polygon is (n - 2) x 180
Sum of interior angles of ABCD = (4 - 2) x 180 = 360º
79 + 2x + (360 - 5x) + 32 = 360
79 + 2x + 360 - 5x + 32 = 360
471 - 3x = 360
3x = 111
x = 37º
Answer:
25(a-2)(a+2)
Step-by-step explanation:
25a^2 -100
We can factor out 25
25(a^2 -4)
a^2 -4 is the difference of squares a^2-b^2= (a-b)(a+b)
where a =a and b=2
a^2 -4 = (a-2)(a+2)
25a^2 -100 = 25(a-2)(a+2)
