Answer:
1 - 4/5-(-1/5)
Step-by-step explanation:
1. - 4/5-(-1/5)
= -0.8+0.2 (if there is a minus sign inside and outside of the parenthesis, when we destroy that parenthesis, both the minus signs will be multiplied and becomes a (+).) (Making it to the percentile).
= -0.6
2. - 4/5-1/5
= -0.8-0.2
= -1
3. -(4/5+1/5)
= -(0.8+ 0.2) (Making those to the percentile).
= -(1) = -1 (When we destroy the parenthesis, if there is a minus sign outside the parenthesis, the result will become a minus.)
From the above expressions, we can see that after calculating, the second and third expressions have the same value, i. e. -1. However, the result of the first expression is different, and we get -0.6. So option one is the right choice.
Answer:
Part A:
The y-intercept is 3.25. This shows the point where the line intersects with the y-axis.
Part B:
The slope was found using the points (1,5) and (5,12). 5 -1 = 4, which is the run. 12- 5 = 7, which is the rise. 7 ÷ 4 = 1.75. This is the slope.
Input b and m;
y = 1.75x + 3.25
Now, input x;
y = 1.75(13) + 3.25
y = 22.75 + 3.25
y = 26

The sum of interior angles of a triangle is 180 degrees. If we’re trying to find the triangles last angle on the right, we will subtract 180-60-50 which equals 70. The angle missing on the right side is 70 degrees. There are opposite angles in this shape so the other angle beside a would also be 70 degrees. Now we only have a left and you do the same thing with the sum of interior angles with that triangle. So you do 180-70-65 and you’re left with 45. Therefore, a is 45 degrees.
(a), (b), (d) and (f) are correct statements
