Step-by-step explanation:
3x^2 - 5x +3 with x= - 4
3x^2 - 5x +3 with x= - 4substitute the x with -4
3×(-4)^2 - 5× (-4) +3=
=3×(-4)×(-4) +20 +3=
=3×16 +20+3=
=48+23=71
Explanation:
Basically, it points out the value of x, meaning you have to define x as that number so you plug -4 for x.
How I plugged it in: 3(-4)^2-5(-4)+3

Answers
Answer:
20(x+3) = 310
20x + 60 = 310
20x + 60 -60 = 310 - 60
20x/20= 250/20

The sum of the measures of angle Y and angle Z is 180 degrees. Angle Y measures (3x + 20) degrees and Angle Z measures x degrees.
A.) write an equation and solve for the value of x.
B.) what is the measure of each angle?
Answers
The question tells us that
y + z = 180
And
y=3x+20
z=x
So we put them in the first formula:
y + z = 180
(3x + 20) + x = 180
Add and get x to one side:
4x + 20 = 180
4x + 20 - 20 = 180-20
4x = 160
Divide both sides by 4
x = 40
B)
Put x back in to equation to get size of each angle:
Y =3x +20
Y=3(40)+20
Y=120+20
Y=140
Z=x
Z=40
Verify: y+z=180
140+40=180
180=180
The variables x and y have a proportional relationship, and y= 5/6 which equation represents this relationship? x= 3/4. Which equation represents this relationship?
Answers
Answer:
(d) y= (1 1/9)x
Step-by-step explanation:
A proportional relation is described by the equation ...
y = kx
Dividing by x shows how to find the value of k:
k = y/x
For the given values of y and x, the value of k is found to be ...
k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9
The relationship is represented by the equation ...
y = (1 1/9)
{30 POINTS!} HELP! Two communications companies offer calling plans. With Company X, it costs 35¢ to connect and then 5¢ for each minute. With Company Y, it costs 20¢ to connect and then 4¢ for each minute. Write and simplify an expression that represents how much more Company X charges, in cents, for n minutes
(35+5n)−(20+4n)
Answers
Answer:
(20 + n)¢
Step-by-step explanation:
With Company X, it costs 35¢ to connect and then 5¢ for each minute.
So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢
Again, With Company Y, it costs 15¢ to connect and then 4¢ for each minute.
So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.
Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)

Five students came for after-school tutoring. Lin’s teacher assigned each of them the same number of problems to complete. Then he assigned each student 2 more problems. 30 problems were assigned in all.
Answers
Answer:
Equation: 5x + 10 = 30
Simplified Equation: 5x = 20
Number of problems assigned per person (at the start): 4
Total number of problems assigned per person: 6
Step-by-step explanation:
Hello!
We know that there were 5 students at the after-school tutoring and that the same number of problems were assigned to each person.
Let x = # of problems assigned to each student.
Since there were 5 students, x is multiplied by 5 so we can represent that as 5x
Next, 2 problems were assigned to each of the 5 students, so that can be represented as 5*2 or 10
If we add both values, they should equal to 30:
5x + 10 = 30
Simplified version: 5x = 20
Value of x : 4

Answers
Answer:
s = 6
Step-by-step explanation:
[tex]\frac{21}{14} =\frac{s}{4}[/tex]
1- cross multiply
21 x 4
= 84
-------------
14 x s
= 14s
SO..
14s = 84
2- to find 's' divide both sides by 14
[tex]\frac{14s}{14} = \frac{84}{14}[/tex]
s = 6
21/14 simplified is 3/2 after you divide by 7. now you need to find a fraction that is equal to 3/2 with a denominator of 4. to do this you multiply both numbers in the fraction 3/2 by 2. you get 6/4. s=6.

Add the two equations together to get:
4y = -4
Solve for y by dividing both sides by 4:
Y = -1
Now you have a value for y, solve for x in the first equation:
2x + 3(-1) = 7
2x -3 = 7
Add 3 to both sides:
2x = 10
Divide both sides by 2:
X = 5
Answer: x = 5 and y = -1

Westin performed an experiment in which he randomly pulled a marble from a bag, recorded its color, put it back, and then repeated. He did this 36 times, and 9 of those times he pulled a purple marble.
Which bags of marbles are good models for this experiment?
Select two that apply.
A ) 4 purple, 5 blue, 2 green, 1 red
B ) 4 purple, 5 blue, 2 green, 1 red
C ) 9 purple, 9 red, 9 green
D ) 9 purple, 9 red, 9 green
E ) 1 purple, 1 blue, 1 green, 1 red
F ) 1 purple, 1 blue, 1 green, 1 red
G ) 4 purple, 4 blue, 4 yellow, 4 orange
Answers
Answer:
Step-by-step explanation:
Based on the experiment, 9 times he pulled a purple marble out of the 36 trials.
That means he has a 1/4 probability of pulling a purple marble
This means that the purple marble ideally makes up one-quarter of the total marble in the bag.
Choice G and F satisfy the condition as stated above.

On average, a largemouth bass weighs about 12 pounds. Two fishermen weighed the largemouth bass they both caught and found their catch weighed 82 pounds. What is the greatest number of largemouth bass caught that are average weight?
Answers
82÷12=6.833333333333
The greatest number of largemouth bass caught is 6.
What is Average?In mathematics, the central value of a set of data is expressed as the average of a list of data. It is defined mathematically as the ratio of the total number of data points to the number of units in the list. In terms of statistics, the term "mean" also refers to the average of a certain set of numerical data.
As per the given data:
Average weight of largemouth bass = 12 pounds
Weight of all largemouth bass caught = 82 pounds
n = number of largemouth bass
Average = (Sum of all observations / Number of observations)
Average weight = (Average weight of largemouth bass / n)
12 = (82 / n)
n = (82 / 12)
n = 6 {considering only integer value}
Hence, the greatest number of largemouth bass caught is 6.
