8x + 3 (3 - x) = 34
A. x = 5
B. x = 2
C. x = 8
D. x = 4
Answer:
A. x=5
Step-by-step explanation:
8x+3(3-x)=34
We move all terms to the left:
8x+3(3-x)-(34)=0
We add all the numbers together, and all the variables
8x+3(-1x+3)-34=0
We multiply parentheses
8x-3x+9-34=0
We add all the numbers together, and all the variables
5x-25=0
We move all terms containing x to the left, all other terms to the right
5x=25
x=25/5
x=5
I think this is correct.
Answer: its A; x=5
Step-by-step explanation:
8x+3(3-x)=34
distribute the 3 through the parentheses
8x+9-3x=34
then add the like terms
5x+9=34
subtract the 9 to the 34
you shoud get
5x=25
then divide the 5 on both sides and you get your answer of x=5

Answer:
three basic methods of graphing linear functions.
The first is by plotting points and then drawing a line through the points.
The second is by using the y-intercept and slope.
The third is applying transformations to the identity function f(x)=x.
true or false:
1. 7 = (-5) - (-12)
2.The difference between -5 and -12 is equal to (-5) - (-12)
3.The difference between -12 and -5 is equal to (-5) - (-12)
4.(-5) + 12 = (-5) - (-12)
5.(-5) + (-12) = (-5) - (-12)
Answer:
1. True
2. False
3. False
4. True
5. False
Step-by-step explanation:
1. 7 = (-5) - (-12)
7 = -5 + 12
7 = 7
2. -5 - 12 = -17
-5 - (-12) = 7
3. -12 - 5 = -17
-5 - (-12) = 7
4. 7 = 7
5. -17 = 7

question down below
Two numbers have a sum of -15 and a
product of -100. What are the numbers?
Answer:
the numbers are -20 and 5
Step-by-step explanation:
The value of a = -20 and b = 5.
Let the numbers be a and b
a + b = -15 ...... i
a × b = -100 ....... ii
From equation i,
a = -15 - b ..... iii
Put equation iii into ii
a × b = -100
(-15 - b) × b = -100
-15b - b² = -100
-15b - b² + 100 = 0
b² + 15b - 100 = 0
b² + 20b - 5b - 100 = 0
b(b + 20) - 5(b + 20) = 0
b - 5 = 0
b = 0 + 5 = 5
a + b = -15
a + 5 = -15
a = -15 - 5
a = -20
Therefore, the value of a = -20 and b = 5.

It costs $3.45 to buy 3/4 ib of chopped walnuts. How much would it cost to purchase 7.5 ibs of walnuts?
Show your work!
Answer:
$3.45
Step-by-step explanation
$3.45 -> 3/4 lb ie (0.75 lb)
x -> 7.5 lb
therefore, x = 7.5 x 3.45/ 0.75
x = 34.5
it costs $3.45 for 7.5 lbs of walnut

Graph the rational function f(x)=(3x-1)/(x-5)
To graph the rational function f(x) = (3x - 1) / (x - 5), follow these steps. Find the vertical asymptote(s) by setting the denominator equal to zero and solving for x.
x - 5 = 0
x = 5
The vertical asymptote of the function is x = 5.
Step 1: Find the horizontal asymptote by comparing the degrees of the numerator and denominator polynomials. Since the degree of the numerator (3x - 1) is 1, and the degree of the denominator (x - 5) is also 1, the horizontal asymptote is given by the ratio of the leading coefficients:
Horizontal asymptote: y = 3/1
Horizontal asymptote: y = 3
Step 2: Find the x-intercept by setting the numerator equal to zero and solving for x:
3x - 1 = 0
3x = 1
x = 1/3
The x-intercept is (1/3, 0).
Step 3: Find the y-intercept by setting x to zero and evaluating the function:
f(0) = (3 * 0 - 1) / (0 - 5)
f(0) = -1 / -5
f(0) = 1/5
The y-intercept is (0, 1/5).
Step 4: Find additional points to sketch the graph. Choose some x-values around the vertical asymptote (x = 5) and calculate the corresponding y-values. For example, you can use x = 4, x = 6, and x = 8.
x = 4:
f(4) = (3 * 4 - 1) / (4 - 5)
= 11 / -1
= -11
x = 6:
f(6) = (3 * 6 - 1) / (6 - 5)
= 17 / 1
= 17
x = 8:
f(8) = (3 * 8 - 1) / (8 - 5)
= 23 / 3
≈ 7.67
Step 5: Plot the points obtained from Steps 2 to 5 and draw the graph. The graph should approach the horizontal asymptote (y = 3) as it approaches the vertical asymptote (x = 5).
The graph of the rational function f(x) = (3x - 1) / (x - 5) should look like this:

Answer:
8.5
Step-by-step explanation:
The opposite of -8 is 8.
\frac{1}{2}+8
Convert 8 to fraction \frac{16}{2}.
\frac{1}{2}+\frac{16}{2}
Since \frac{1}{2} and \frac{16}{2} have the same denominator, add them by adding their numerators.
\frac{1+16}{2}
Add 1 and 16 to get 17.
\frac{17}{2}
