Which expression is equivalent to the given expression? −(2n−6)
A)−2(n−3)
B)2(n−6)
C)2n−6
D) 2n + 6
Answer:
Option A [tex]-2(n-3)[/tex]
Step-by-step explanation:
we have
[tex]-(2n-6)[/tex]
Eliminate the parenthesis
[tex]-(2n-6)=-2n+6[/tex]
Verify each case
case A) [tex]-2(n-3)[/tex]
[tex]-2(n-3)=-2n+6[/tex]
therefore
[tex]-2n+6=-2n+6[/tex] -----> is true
case A is equivalent to the given expression
case B) [tex]2(n-6)[/tex]
[tex]2(n-6)=2n-12[/tex]
therefore
[tex]-2n+6\neq2n-12[/tex]
case B is not equivalent to the given expression
case C) [tex]2n-6[/tex]
we have that
[tex]-2n+6\neq2n-6[/tex]
therefore
case C is not equivalent to the given expression
case D) [tex]2n+6[/tex]
we have that
[tex]-2n+6\neq2n+6[/tex]
therefore
case D is not equivalent to the given expression

A baseball team has $1,400 to buy baseball uniforms. Each uniform costs $124. Does the team have enough money to buy 11 baseball uniforms? Use the drop-down menus to explain.
The total cost for 11 uniforms is
1.264
1364
1480
1488
The cost of 11 baseball uniforms will be the multiplication of 11 to 124 which is $1364 thus it is enough to buy the uniforms and the team will be left with $36 so option (B) will be correct.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
Multiplication = to multiply any two or more numbers or variables called multiplication.
As per the given question,
Each uniform costs $124.
Number of uniforms needed to buy = 11
Cost of 11 uniform = 11 × 124 = $1364
The budget $1400 > $1364 therefore it is enough.
Hence "The cost of 11 baseball uniforms will be the multiplication of 11 to 124 which is $1364 thus it is enough to buy the uniforms".

Make a table of ordered pairs for the equation.
y=−13x+4y=−13x+4
Then plot two points to graph the equation.
Solution-
The given equation,
[tex]y=-13x+4[/tex]
Then, we have to calculate two points that satisfy the equation,
Calculating y for x = 0,
[tex]y(0)=-13(0)+4=4[/tex]
So, point (0, 4) satisfies the equation.
Calculating y for x = 1,
[tex]y(1)=-13(1)+4=-13+4=-9[/tex]
So, point (1, -9) satisfies the equation.
Plotting the graph taking this two points, as shown in the attachment.

The correct answer for product in lowest term of the expression [tex]\dfrac{8}{15} * \dfrac{-3}{10}[/tex] is [tex]\dfrac{-4}{25}[/tex]. The correct option is 1.
To calculate the product of fractions in lowest terms, multiply the numerators together and multiply the denominators together, Then simplify the resulting fraction.
A fraction can be simplified in it's lower term , if both the numerator and denominator after simplification have no common factor other than 1.
The given fractions are:
[tex]\dfrac{8}{15}[/tex] and [tex]\dfrac{-3}{10}[/tex].
To simplify, Multiply both numerator and denominator.
[tex]\dfrac{8}{15} * \dfrac{-3}{10}[/tex]
= [tex]\dfrac{-24}{150}[/tex]
Simplify further, Divide both numerator and denominator by their greatest common divisor, which is 6.
[tex]= \dfrac{\dfrac{-24}{6}}{\dfrac{150}{6}}[/tex]
= [tex]\dfrac{-4}{25}[/tex]
The product of [tex]\dfrac{8}{15}[/tex] and [tex]\dfrac{-3}{10}[/tex] in lowest terms is [tex]\dfrac{-4}{25}[/tex]. The correct option is 1.

there 12 beads on the bracelet. 8 of the beads are purple. what percent of the beads are purple
There are 12 beads on the bracelet and 8 of the beads are purple. What percent of the beads are purple?
The fraction [tex]\frac{8}{12}[/tex] represents the number of purple beads on the bracelet out of all the beads on the bracelet.
To find what percent of the beads are purple, we can turn the fraction [tex]\frac{8}{12}[/tex] to a percent.
We can first reduce the fraction [tex]\frac{8}{12}[/tex] by dividing both the numerator and denominator by the Greatest Common Factor of 8 and 12 using 4.
8 ÷ 4 = 2
12 ÷ 4 = 3
Our reduced fraction is [tex]\frac{2}{3}[/tex]
2 ÷ 3 = 0.66666666666667
0.66666666666667 × 100 = 66.666666666667%
Therefore, 66.666666666667% of the beads on the bracelet are purple.

A city is paving a bike path. The same length of path is paved everyday. After 4 days, there are 8 miles of path remaining to be paved. After 6 more days, there are 5 miles of path remaining to be paved.
a. Explain how you know the situation can be modeled by a linear equation.
b. Write an equation that gives the distance (in miles) as a function of the number of days since the project began.
c. In how many more days will the entire path be paved?
The linear equation is y = (-3/2)x + 14 and the number of days will be 10 days.
What is a linear equation?It is described as the relationship between two variables, and a straight line results from plotting the graph of the linear equation.
The equation is referred to as a linear equation in one variable if just one variable is contained in the linear equation.
It is given that:
A city is paving a bike path.
The same length of the path is paved every day. After 4 days, there are 8 miles of path remaining to be paved.
After 6 more days, there are 5 miles of path remaining to be paved.
The coordinates are (4, 8) and (6, 5)
The linear equation can be modeled:
[y - 5] = (5-8)/(6-4)[x-6]
y - 5 = -3/2[x - 6]
2y - 10 = -3x + 18
2y = -3x + 28
y = (-3/2)x + 14
Plug y = 0
(-3/2)x + 14 = 0
x = 28/3
x = 9.33 ≈ 10 days
Thus, the linear equation is y = (-3/2)x + 14 and the number of days will be 10 days.

Xin graphs the equation y= 4x-6. Select all the statements that are true. The graph is a curve line, The line passes through the origin, go on passes through the point(0,6) , The slope of the line is 4 , The Y intercept of the line is -6
Answer:
The slope of the line is 4.
The Y intercept of the line is -6.
Step-by-step explanation:
The slope intercept form of a line is
[tex]y=mx+b[/tex] .... (1)
where, m is slope and b is y-intercept.
The given equation of line is
[tex]y=4x-6[/tex] .... (2)
On comparing (1) and (2) we get
[tex]m=4[/tex]
[tex]b=-6[/tex]
It means the slope of the line is 4 , The Y intercept of the line is -6. the graph of a linear function is a straight line.
The value of y is -6 at x=0, so the line do not passes through the origin.
Therefore, the correct statements are "the slope of the line is 4 and the Y intercept of the line is -6".
The solutions are
The slope of the line is 4
The y-intercept of the line is –6
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y coordinate of second point
y₁ = y coordinate of point one
m = slope
x = x coordinate of second point
x₁ = x coordinate of point one
Given data ,
Let the equation be y = 4x - 6
Now , the equation is of the form y = mx + b where m is the slope and b is the y-intercept
Therefore , the slope of the equation is m = 4
And the y intercept is -6
Hence ,
The slope of the line and the y-intercept of the line is –6
