Answer:
34
Step-by-step explanation:
We start by working out the slope. The slope is change in y over change in x, so (66-58)/(-56)-(-42) is the slope here. 66-58 is 8, and -56-(-42) is -14. -8/14=-4/7. The equation of a line in slope-intercept form is y=mx+b where b is the y intercept and m is the slope. Since the slope is -4/7, then y=-4/7x+b. We then insert any x and y pair into this equation and solve for b, the y intercept to get it. (We can do ANY pair) So, 50=(-4/7)(-28)+b.
: 50=16+b
: 50-16=b
: 34=b
So, in conclusion, the y intercept is 34. Hope this helps!
The total surface area is 121.8yd^2 and the lateral surface area is 79.8yd^2.
121.8 - 79.8 = 42
Ok let’s solve it
5(x-2)^2-20=0
first let’s foil (x-2)
5(x^2-4x+4) -20=0
now distribute the 5
5x^2 -20x +20 -20 = 0
combine like terms
5x^2-20x=0
take the gcf
5x(x-4)=0
x=0, 4
solutions are (4,0) and (2, -20) because the original vertex form a(x-h)^2+k
12 + 3 [5 + (4-2)] =
12 + 3 [ 5 + 2 ] =
12 + 3 [ 7] =
12 + 21 =

Answer:
0
Step-by-step explanation:
If the answer is between 0 to 0.49, the best estimate is 0.
If the answer is between 0.5-1.49, the best estimate is 1.
If the answer is 1.5 or greater, the best estimate is 2.
Without giving the fractions 1/10 and 1/12 a common denominator, we know the answer is between 2/12 and 2/10.
2/12 is less than 2/10. 2/10 is 0.2, which is less than 0.5.
Since the final answer is less than 0.5, the best estimate is 0.
