Answer:
The answer is
<h2>135°</h2>
Step-by-step explanation:
In order to convert a value from radians to degrees we multiply the value by 
So from the question the value to be converted into degrees is
<h3>
</h3>
<u>Converting into degrees we have</u>
<h3>
</h3>
<u>Reduce the expression with π</u>
That's
<h3>
</h3>
We have the final answer as
<h3>135°</h3>
Hope this helps you
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
Found this when I was doing my own work, hope this helps.
Answer: B. y = 1/2x - 1
Explanation:
I know someone else already answered, but I wanted to explain why the answer is B.
Consider an equation of a line in slope-intercept form: y = mx + b
Since the line intersects the y-axis at -1, that’s the y intercept, or b. We know the slope of the line is positive because it slopes upward from left to right. From each whole number solution point, the line goes up one and two to the right. Slope, represented by m, is “rise” over “run”, or the change in y over the change in x. This makes the slope 1/2.
I hope this helps.
