Option 2: whenever it’s < or > it’s a dashed line but when it’s <= or >= it’s a solid line
Option 4: if you’ll insert (0,0) in the equation then you’ll get 0>-2 which is true so (0,0) is a solution. Another way to check is if (0,0) is in the shaded region of the graph
Option 5: in the equation-2 is the y-intercept which proves it intersects at (0,-2) on the y-axis
Answer: 5(x+1)
Step-by-step explanation:
Let the number be x
Sum of number and 1 is x+1
5 times the sum is 5(x+1)
The answer to the above question can be explained as under -
We know that, the sum of angles of triangle is 180°.
So, vertex angle plus base angles are equal are equal to 180°.
Let the vertex angle be represented by "v" and base angles be represented by "b".
Thus, v + b + b = 180°
So, v + 2b = 180°
Next, the question says, the vertex angle is 20° less than the sum of base angles.
Thus, 2b - 20° = v
<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>
I’m guessing the question is written as (-6)^-1x=27^-1
to get rid of a negative exponent, you use the reciprocal of the number.
so (-6)^-1 would be 1/-6
27^-1 would be 1/27
rewrite is as
(1/-6)x = 1/27
multiply both sides by reciprocal or 1/-6 to cancel it and make x by itself
it’s would be x = 1/27(-6)
multiply
x = -6/27
simplify
the final answer is x=-2/9
