Answer:
Step-by-step explanation:
we have the set
[tex]3m+4n = 2\\\\5m-4n = 14[/tex]
add them both
[tex](3m+4n)+(5m-4n) = 2+14\\\\(3m+5m)+(4n-4n) = 16\\\\8m=16\\\\m = \frac{16}{8}\\\\m = 2[/tex]
now plug in m = 2 in equation 1 (it could aso be equation 2)
[tex]3m+4n = 2\\\\3(2)+4n = 2\\\\6+4n = 2\\\\4n = 2-6\\\\4n = -4\\\\n = -1[/tex]
so the solution is
m = 2
n = -1

Find the roots of the equation 3x^2 - 2x + 4 = 2x^2 - 4 in simplest form
Answer:
3 x 2 − 2 x + 4 = 2 x 2 − 4
Step-by-step explanation:
Write the problem as a mathematical expression.
3 x 2 − 2 x + 4 = 2 x 2 − 4
Subtract 2 x 2 − 4 from both sides of the equation.
3 x 2 − 2 x + 4 − 2 x 2 − 4 = 0
Simplify each term.
Subtract 4 from 2 . 3 x 2 − 2 x + 4 − 2 x − 2 = 0
Rewrite the expression using the negative exponent rule
b − n =1 b n . 3 x 2 − 2 x + 4 − 2 1 x 2 = 0
Combine − 2 and 1 x 2 . 3 x 2 − 2 x + 4 + − 2 x 2 = 0
Move the negative in front of the fraction.
3 x 2 − 2 x + 4 − 2 x 2 = 0

David rode his bicycle for 6 hours and jogged for 8 hours during the
week. If he continues bicycling and jogging at the same rate, how
many hours will he jog if he bikes for 54 hours?
( Plz help :,) )
Answer:
72 hours
Step-by-step explanation:
Because if he bikes 54 then he will need to do 8 x 9 = 72 because if he biked 54 hours then he did 6 x 9 = 54 so the answer is 72 hours (u multiply by 9) hope this helps
The width of the rectangle is 5x-4. The length of the rectangle is 5
What is the simplified expression for the area of the rectangle?
Answer:
The area of the rectangle A = 25x² - 20x
Step-by-step explanation:
Given
The width of the rectangle = w = 5x - 4
The length of a rectangle = l = 5x
To determine
The area of the rectangle = ?
Using the Formula to determine the area of the rectangle
[tex]A = wl[/tex]
substitute w = 5x - 4 and l = 5x in the formula
[tex]A = (5x-4) (5x)[/tex]
Apply distributive law: a(b-c) = ab - ac
[tex]=\left(5x\right)\cdot \:5x-\left(5x\right)\cdot \:4[/tex]
[tex]=5x\left(5x\right)-4\left(5x\right)[/tex]
as 5x(5x) = 25x² and 4(5x) = 20x, so
[tex]=25x^2-20x[/tex]
Therefore, the area of the rectangle A = 25x² - 20x

Last week the office used boxes of paper. This week they used boxes of paper. How many more boxes did they use last week than this week?
Lol I need help again
Answer:
Nope no help. :d
Step-by-step explanation:
One evening, 1255 people went to the movies to see Gone with the wind. The box office receipts totaled to 12,295. The price of admission for adults is $10.00 and for children, it is $7.00. Write an equation for how many people went to see the movie. Write an equation for the amount of money made at the box office. How many of each type of ticket did they sell (adult and children)?
Answer:
Number of adult tickets sold = 1170
Number of children tickets sold = 85
Step-by-step explanation:
Let,
x be the number of adult tickets sold
y be the number of child tickets sold
According to given statement;
x+y = 1255 Eqn 1
10x+7y=12295 Eqn 2
Multiplying Eqn 1 by 10
10(x+y=1255)
10x+10y=12550 Eqn 3
Subtracting Eqn 2 from Eqn 3
(10x+10y)-(10x+7y) = 12550 - 12295
10x+10y-10x-7y= 255
3y = 255
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{255}{3}\\y=85[/tex]
Putting y=85 in Eqn 1
x+85 = 1255
x = 1255-85
x = 1170
Hence,
Number of adult tickets sold = 1170
Number of children tickets sold = 85
A piece of wire is 76cm long. It is cut into two unequal parts and each part is bent into a square. The sum of the areas of the two squares is 205cm². Find the length of the shorter part of the wire.
Answer:
The length of the shorter part of the wire is 24 centimeters.
Step-by-step explanation:
Let [tex]L[/tex] the total length of the piece of wire, where [tex]L-x[/tex] and [tex]x[/tex] are the perimeters of the greater and lesser squares. All lengths are measured in centimeters. Since squares have four sides of equal length, the side lengths for the greater and lesser squares are [tex]\frac{L-x}{4}[/tex] and [tex]\frac{x}{4}[/tex]. From statement we find that the sum of the areas of the two squares ([tex]A[/tex]), measured in square centimeters, is represented by the following expression:
[tex]A = \left(\frac{L-x}{4} \right)^{2}+\left(\frac{x}{4} \right)^{2}[/tex] (1)
And we expand this polynomial below:
[tex]A = \frac{L^{2}-2\cdot L\cdot x +x^{2}}{16} + \frac{x^{2}}{16}[/tex]
[tex]A = \frac{L^{2}-2\cdot L\cdot x +2\cdot x^{2}}{16}[/tex]
[tex]2\cdot x^{2}-2\cdot L\cdot x +L^{2}-16\cdot A = 0[/tex] (2)
If we know that [tex]L = 76\,cm[/tex] and [tex]A = 205\,cm^{2 }[/tex], then the length of the shorter part of the wire is:
[tex]2\cdot x^{2}-152\cdot x +2496 = 0[/tex]
By the Quadratic Formula, we determine the roots associated with the polynomial:
[tex]x_{1} = 52\,cm[/tex], [tex]x_{2} = 24\,cm[/tex]
The length of the shorter part of the wire corresponds to the second root. Hence, the length of the shorter part of the wire is 24 centimeters.

the functions f and g are such that f(x) =3x-2 and g (x)=x-3
1 calculate the valve of g (-2)
ANSWER FAST!!!!!!!
Answer:
The value of g(-2) = -5
Step-by-step explanation:
Explanation:-
Given functions are f (x) = 3 x - 2 and g(x) = x-3
Given g (x) = x-3
Put x = -2 in g (x) = x-3
⇒ g ( -2 ) = - 2 -3 = -5
The value of g(-2) = -5
Which equation represents the rectangular form of r = 4cos(θ)?
(x – 2)2 + y2 = 4
(x + 2)2 + y2 = 4
(x – 2)2 + y2 = 0
(x + 2)2 + y2 = 0
Answer:
a. (x – 2)2 + y2 = 4
Step-by-step explanation:
edge 2021
The rectangular form of [tex]\mathbf{r = 4cos(\theta)}[/tex] is (a) [tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]
The polar coordinate is given as:
[tex]\mathbf{r = 4cos(\theta)}[/tex]
Multiply both sides of [tex]\mathbf{r = 4cos(\theta)}[/tex] by r
[tex]\mathbf{r \times r= 4cos(\theta) \times r}[/tex]
Evaluate
[tex]\mathbf{r^2= 4rcos(\theta) }[/tex]
As a general equation, we have:
[tex]\mathbf{x^2 + y^2 = r^2}[/tex]
Substitute [tex]\mathbf{x^2 + y^2 = r^2}[/tex] in [tex]\mathbf{r^2= 4rcos(\theta) }[/tex]
[tex]\mathbf{x^2 + y^2= 4rcos(\theta) }[/tex]
Also as a general equation, we have:
[tex]\mathbf{x = rcos(\theta)}[/tex]
So, [tex]\mathbf{x^2 + y^2= 4rcos(\theta) }[/tex] becomes
[tex]\mathbf{x^2 + y^2= 4x}[/tex]
Subtract 4x from both sides
[tex]\mathbf{x^2-4x + y^2= 0}[/tex]
Complete the square on x^2 - 4x
[tex]\mathbf{(x - 2)^2-2 + y^2= 0 + 2}[/tex]
Add 2 to both sides
[tex]\mathbf{(x - 2)^2 + y^2= 0 + 2+2}[/tex]
[tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]
Hence, the rectangular form of [tex]\mathbf{r = 4cos(\theta)}[/tex] is (a) [tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]

A student argues that Y= X/9 does not represent a proportional relationship between X and because we need to multiply one variable by the same constant to get the other one and not divide it by a constant. Do you agree or disagree with this student?
Answer:
Disagree
Step-by-step explanation:
disagree. dividing by 9 is the same as multiplying by 1/9. we can look at the equation y = x/9 as y = 1/9x. also, y/x = 1/9 is constant for all corresponding values of x and y

What is the probability that exactly 2 of the 5 trees have the virus? You may round your answer to the nearest hundredth. P(X=2)=P(X=2)=P, left parenthesis, X, equals, 2, right parenthesis, equals
Answer:
0.05
Step-by-step explanation:
Given that:
Number of samples, n = 5
Proportion, p = 80% = 0.8
P(x = 2)
Using binomial distribution formula ;
P(X = x) = nCx * p^x * (1 - p)^(n-x)
P(x = 2) = 5C2 * 0.8^2 * (1 - 0.8)^(5-2)
P(x = 2) = 5C2 * 0.8^2 * 0.2^3
P(x = 2) = 10 * 0.64 * 0.008
P(x = 2) = 0.0512
= 0.05 ( nearest hundredth)
