Write an expression equivelant to 5x - 2
Which interval is the solution set to 0.35x – 4.8 < 5.2 – 0.9x?
Answer:
(-∞,8)
Step-by-step explanation:
So the interval for the solution of a certain set is the numbers that can be used as value for X in the set and the set still be true, in order to solve this, you just need to solve the set by making it an equation:
0.35x – 4.8 < 5.2 – 0.9x
0.35x – 4.8 =5.2 – 0.9x
0.35x+0.9x=5.2+4.8
1.25x=10
x=8
So the maximum value of X will be 8, and when X is a negative value the set is true, so the interval would be all real numbers form -infinite to 8.
(-∞,8)

Find the Sum (3x^2+ 4x-1) + (-2x^2 -3x+2)
The sum of the equation is A = x² + x + 1
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the sum of the equations be represented as A
Now , the value of A is
Let the first equation be P
The value of P = 3x² + 4x - 1
Let the second equation be Q
The value of Q = -2x² - 3x + 2
Now , the value of A = P + Q
Substituting the values in the equation , we get
A = ( 3x² + 4x - 1 ) + ( -2x² - 3x + 2 )
On simplifying the equation , we get
A = ( 3x² - 2x² ) + ( 4x - 3x ) + ( 2 - 1 )
A = x² + x + 1
Therefore , the value of A is x² + x + 1
Hence , the equation is A = x² + x + 1

Hermes has eight envelopes labeled "x" and an additional $218, and Apollo has five envelopes labeled "x" and an additional $521.Each envelope has the same amount of money in it.
a) Write a system of equations representing this situation
b) How much money must be in each envelope for them to have the same amount of money?
Answer:
a) [tex]\left \{ {{8x+218=y} \atop {5x+521=y}} \right.[/tex], b) $101
Step-by-step explanation:
Hermes: 8 envelopes, $218
Apollo: 5 envelopes, $521
If x is the amount in each envelope, H is the amount Hemes has and A is the amount Apollo has, this would be a possible system of equations.
[tex]\left \{ {{8x + 218 = H} \atop {5x +521 = A}} \right.[/tex]
If Apollo and Hermes both had the same amount of total money, A and H could equal y
[tex]\left \{ {{8x+218=y} \atop {5x+521=y}} \right.[/tex]
We want to find the amount in each envelope (x), so we can substitute y in the first equation for y in the second equation:
[tex]8x+218=5x+521[/tex]
Subtract [tex]5x[/tex] from both sides
[tex]3x+218=521[/tex]
Subtract 218 from both sides
[tex]3x=303[/tex]
Divide both sides by 3
[tex]x=101[/tex]
So there would have to be $101 in both envelopes for Apollo and Hermes to have the same amount of total money.

Write the equation of the line that passes through the points (-1,-4) and (9,-5).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
The equation in point-slope form is: [tex]y+4=\frac{-1}{10}(x+1)[/tex]
Step-by-step explanation:
Write the equation of the line that passes through the points (-1,-4) and (9,-5).
The point slope form is: [tex]y-y_1=m(x-x_1)[/tex]
Where m is slope and x₁ and y₁ are the points given
Finding Slope
Slope can be found of given points using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=-1, y_1=-4, x_2=9, y_2=-5[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-5-(-4)}{9-(-1)}\\ Slope=\frac{-5+4}{9+1}\\ Slope=\frac{-1}{10}[/tex]
So, slope m = -1/10
Using point (-1,-4) and slope m = -1/10 the equation is:
[tex]y-y_1=m(x-x_1)\\y-(-4)=\frac{-1}{10}(x-(-1))\\y+4=\frac{-1}{10}(x+1)[/tex]
So, the equation in point-slope form is: [tex]y+4=\frac{-1}{10}(x+1)[/tex]

Subtract the mixed fractions 7 1/4 - 2 4/5=
Answer:
4 9/20
Step-by-step explanation:
Convert the mixed fractions to improper fractions first:
7 1/4--> 29/4, 2 4/5--> 14/5.
Now we look for the common denominator, which is 20. So 29/4=145/20 and 14/5=56/20.
We subtract them:
145/20-56/20=89/20.
Convert it to a mixed fraction to get 4 9/20.
The difference of the given mixed fractions is [tex]4\frac{9}{20}[/tex].
Given that, [tex]7\frac{1}{4} -2\frac{4}{5}[/tex].
What is subtraction of fractions?Subtracting fractions include the subtraction of two or more fractions with the same or different denominators. Like fractions can be subtracted directly but for unlike fractions we need to make the denominators same first and then subtract them.
Here, [tex]7\frac{1}{4}[/tex] can be written as 29/4 and [tex]2\frac{4}{5}[/tex] can be written as 14/5
Now, 29/4 - 14/5
= 145/20 - 56/20
= 89/20
= [tex]4\frac{9}{20}[/tex]
Therefore, the difference of the given mixed fractions is [tex]4\frac{9}{20}[/tex].

the answer Is b
2.5
The situation is represented by the table:
The tank initially had 1200 gallons of water.
The tank is leaking at the rate of 2.5 gallons per hour.
Option B is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
From the table, we see that,
After 4 hours there are 1190 gallons of water left.
After 8 hours there are 1180 gallons of water left.
Now,
The rate of change.
= (1180 - 1190)/ (8 - 4)
= -10/4
= -5/2
= -2.5
This means,
There is a decrease of 2.5 gallons per hour.
Now,
The amount of water the tank initially had.
= 1190 + 4 x 2.5
= 1190 + 10
= 1200
Thus,
The tank initially had 1200 gallons of water and it's leaking at the rate of 2.5 gallons per hour.
