3(4-2x) =-x+1 plz help
Answer:
The answer is 11/5.
Step-by-step explanation:
First, multiply 3 and 4 together. Do the same with 3 and -2x. Now you should have −6x + 12 = −x + 1. Now, add x to both sides. You should have −5x + 12 = 1. Now subtract 12 to both sides. You should have -5x = -11. Divide both sides by -5. Since -11 and -5 both have the negative sign, they cancel out. You should now get the answer, 11/5! Have a good day!

Don't shame I'm just trying to pass, my assignment's weigh 35% of my grade, right now my assignment percentage is 65%. My test which holds 45% of my grade is at 85% and my final is 20%, which I got a 90 on. If I take 7 0's in assignments, what would my grade be? Basically asking how many 0's under assignments can I basically take so I do not fail. Hope this makes sense
Answer:
Step-by-step explanation:
Let's start by weighing everything but the assignments. We'll get back to them momentarily.
You have 85% on 45% of your grade. That's 38.25
Your final weighs in at 20%. You have. 18
So your total so far is 56.25
Now that looks mighty low, but we haven't put in the assignments yet.
So by the time you are finished you will have done 41 out of 48 assignments and that means you have done (41/48)*100 = 85.41 of the work. On these assignments that you have done, you averaged 65%
So your assignment mark will be 0.65 * 85.41 = 55.52
The weighted average = 0.35
The mark you will get is 0.35 * 55.52 = 19.32
So your final grade will be 56.25
Grade 75.57

A wrestler competes in 31 matches. Of those matches, he wins 14. What percent of the matches did the wrestler win? Round your answer to the nearest tenth place if necessary. (Use any method to solve this question, but you must show work) *
Answer: The wrestler won 45% of their matches.
Step-by-step explanation:
When are trying to find percentages, we are finding part of a whole. 31 is the whole and the part is 14.
If I was to set [tex]\frac{14}{31}[/tex] to an equivlent fraciton of over 100, we would get something close to 45.
5/2y=10 for y
Also, could you explain how to do it, I'm having difficulties and I would like to know how to do this problem.
Answer:
y = 4
Step-by-step explanation:
5/2y = 10
5/2y x 2/5 = 10 x 2/5
Multiply each side by the reciprocal
y = 4
find the value of x in the proportion.

A line passes through the point (2,3) and has a slope of -2. Which is the equation of the line in point-slope form?
Answer:
7-2x=y
Step-by-step explanation:
When a point passes through a line it satisfies its equation
(X-x0 )m= y-y0
Slope = m = -2
(X-2 )(-2)=y-3
4-2x=y-3
7-2x=y

Answer:
RP = 2.3
PQ = 1.0
RQ = 2.3
Step-by-step explanation:
The pictures says RP = RQ,
so:
3x - 0.4 = x + 1.4
this you can simplify to:
x = 0.9
Then fill x in:
RP = 3*0.9 - 0.4 = 2.3
PQ = 0.9 + 0.1 = 1.0
RQ = 2.3
The function f(x) is defined below. What is the end behavior of f(x)?
f(x)=123x^3+9x^4-768x-3x^5-189x^2+1260
Answer:
Rises to the left and falls to the right
Step-by-step explanation:
Use the degree and the leading coefficient to determine the behavior.
The end behavior will be as x approaches infinity, and negative infinity, f(x) approaches infinity.
What is a function?
Function is a type of relation, or rule, that maps one input to specific single output.
The function f(x) is defined as;
f(x)= 123x³+9[tex]x^4[/tex] - 768x - 3[tex]x^5[/tex] - 189x² + 1260
WE need the degree and the leading coefficient to determine the behavior.
Since our leading coeffeicent has a leading even degree of 5, and a positive number,
The function will Rises to the left and falls to the right.
The end behavior will be as x approaches infinity, and negative infinity, f(x) approaches infinity.

Factor out 2x squared minus 98 completely
Answer:
2(x+7)(x-7)
Step-by-step explanation:
1. In 2x^2-98, there is a common factor of 2
2. The equation therefore becomes 2 (x^2 - 49)
3. We know that x^-49 is a difference of two squares and can therefore be factored into (x+7)(x-7)
4. Therefore the fully factored answer is 2(x+7)(x-7)
The table below shows the number of pencils and pens three friends have in their backpacks.
Who has a greater ratio of pencils to pens?
A. Lydia
B . Angel
C . Elizabeth
Answer:
Angel has a greater ratio of pencils to pens.
i.e. Angle's pencils to pens = 3 / 2 or 63/42
Thus, option (B) is true.
Step-by-step explanation:
Considering the table
Lydia's Number of Pencils = 10
Lydia's Number of Pens = 7
Lydia's Pencils to Pens ratio = 10/7
Angel's Number of Pencils = 9
Angel's Number of Pens = 6
Angels's Pencils to Pens ratio = 9/6 = 3 / 2
Elizabeth's Number of Pencils = 12
Elizabeth's Number of Pens = 9
Elizabeth's Pencils to Pens ratio = 12/9 = 4 / 3
So, We get the inputs ratios such as:
Lydia's ratio: Angels's ratio: Elizabeth's ratio
10/7 : 3 / 2 : 4 / 3
As the least common denominator (LCD) is: 42
Rewriting as equivalent fractions with the LCD:
10/7 : 3 / 2 : 4 / 3
60 / 42 : 63/42 : 56/42
Sorting from least to greatest:
Sorting this table by the numerators of the equivalent fractions in order from least to greatest:
Elizabeth's ratio : Lydia's ratio : Angels's ratio:
4/3 : 10 /7 : 3 / 2
56/42 : 60 / 42 : 63/42
Therefore, Angel has a greater ratio of pencils to pens.
i.e. Angle's pencils to pens = 3 / 2 or 63/42
Thus, option (B) is true.
