For the first, simply plug in the value of x given (x = 2) into the equation: [tex]\left\frac{3}{4}x^2 + 5\right.|_{x=2} = \frac{3}{4}\left ( 2^2 \right )+5 = 8.[/tex]
So, 8 would be your answer.
For the second, the sum of x and 2 would be expressed as x + 2. Twice this sum would be written as 2(x+2). Finally, 8 less than twice that sum would be written as 2(x+2) - 8, which would be your expression.
For the last question, the coefficient refers to the number directly in front of the variable, x. So you need only to check what the x would simplify to in each equation and look for the expression where x has no coefficient (i.e., its coefficient is 1). For Hunter, the coefficient would be 15 (5 × 3x = 15x); for Michael, the coefficient would be 11 (6x + 5x = 11x); for Nate, the coefficient would be 1 (x = 1x); and for Spencer, the coefficient would be 2 (2x = 2x). Thus, Nate's expression has a coefficient of 1 when simplified.

sooo what can we set equal
note the lines have the same lenght, therefore the arc length will also be the same, then they give us the other two lengths to make the entire circle , yay
so then just set all the arc lengths equal to 360 °
(3x+ 30) + (3x + 30 ) + 2x + 4x = 360 ( put like terms together )
12x + 60 = 360 ( subtract 60 from both sides )
12x = 300 ( divide both side by 12 )
x = 25
nice we now know X :)
A stock's value in dollars changed by -5.75 on Monday and +3.25 on Tuesday. Which statement correctly compares the changes in the stock's value?
Answers
Complete Question:
A stock’s value in dollars changed by -5.75 on Monday and +3.25 on Tuesday. Which statement correctly compares the changes in the stock’s value?
A. The value changed more on Monday because |-5.75| greater than |3.25|.
B. The value changed more on Monday because -5.75 less than 3.25.
C. The value changed more on Tuesday because +3.25 greater than 0.
D. The value changed more on Tuesday because 3.25 greater than. 25.75.
Answer:
A. The value changed more on Monday because |-5.75| greater than |3.25|.
Step-by-step explanation:
Given
[tex]Monday = -5.75[/tex]
[tex]Tuesday =+3.25[/tex]
Required
Correct statement about the stock changes
First, calculate the absolute values of both changes:
[tex]Monday = |-5.75|[/tex]
[tex]Monday = 5.75[/tex]
[tex]Tuesday = |+3.25|[/tex]
[tex]Tuesday = 3.25[/tex]
Compare

Answer:
f(x)=x+2
Step-by-step explanation:
Pick any two points from the question and plug them into the equation y2-y1/x2-x1. In this case, I picked (0,2) and (1,3). Therefore, the equation will be 3-2/1-0. Simplify this to get 1/1 which is equal to 1. Therefore, the slope is equal to 1. Then pick a point and plug it into the point slope form equation which is y-y1=m(x-x1) where m is the slope. In this case, I picked (0,2). Therefore, the equation will be y-2=(x-0). Simplify this to get y-2=x. You want to isolate y so you have to add 2 to both sides. This will make the equation y=x+2 which is the answer. Therefore, the answer is y=x+2 or f(x)=x+2.
