show that each quadrilateral with the given vertices is a parallelogram.
J(-2,-2), K(-3,3), L(1,5), M(2,0)
Answers
9514 1404 393
Answer:
J +L = K +M = (-1, 3)
Step-by-step explanation:
The figure JKLM is a parallelogram if the midpoints of the diagonals are the same point. That is, ...
(J +L)/2 = (K +M)/2
Multiplying by 2 makes this a simpler test:
J +L = K +M
In this quadrilateral, those sums are ...
J +L = (-2, -2) +(1, 5) = (-2+1, -2+5) = (-1, 3)
K +M = (-3, 3) +(2, 0) = (-3+2, 3+0) = (-1, 3)
The midpoints are the same, so the quadrilateral is a parallelogram.

1.) Find the LCF of 8 and 4:[tex]8,4=8[/tex]- We do this because in order to add the fractions together, they have to have the same denominator. In this case you find the LCF, (Least Common Factor) of 8 and that turns into the denominator for both.
2.) Convert the fractions to have the same denominator: [tex]\frac{5}{8}=\frac{5}{8}[/tex][tex]\frac{3}{4}=\frac{6}{8}[/tex]- [tex]\frac{5}{8}[/tex] stays the same, but [tex]\frac{3}{4}[/tex] changes to [tex]\frac{6}{8}[/tex] because the LCF if 8, and to get to 8 we had to multiply 4 by 2. So since we multiplied the denominator, you must do the same to the numerator, hence why we went from 3 to 6.
3.) Add the numerators: [tex]5+6=11[/tex]- Since [tex]\frac{5}{8}[/tex] and [tex]\frac{6}{8}[/tex] have the same denominator, all you have to do is add the numerator.

Answers
Answer:
m = 4
Step-by-step explanation:
Given
- 2(m + 3) - 5m = - 34 ← distribute and simplify left side
- 2m - 6 - 5m = - 34
- 7m - 6 = - 34 ( add 6 to both sides )
- 7m = - 28 ( divide both sides by - 7 )
m = 4

The opening judgment of Fever 1793," From the moment Colette Ogilvie passed out, Philadelphia's church bells chimed continuous.
The narrator of Fever 1793 makes it easy for readers to picture her upbringing by expressing her love for the nation, describing how it felt to see her words printed, confessing to counting on her fingers, and describing how it felt to voice her anger with front-of-the-house service.
On the road corners, shots were fired, and a cannon was fired in the public forecourt to clear the air. In addition to that, hornets, blowflies, and mosquitoes swarmed about us continuous.

State the domain restriction(s) in interval notation of \displaystyle f\left(g\left(x\right)\right)f(g(x)) given: \displaystyle f\left(x\right)=\sqrt{3x-2}f(x)= 3x−2 and \displaystyle g\left(x\right)=x-7g(x)=x−7
Answers
Answer:
The interval notation for the domain is [tex][\frac{23}{3},\infty ][/tex].
Step-by-step explanation:
Consider the provided information.
It is given that [tex]\:f\left(x\right)=\sqrt{3x-2},\:\text{ and }\:g\left(x\right)=x-7[/tex]
We need to find the value of [tex]f\left(g\left(x\right)\right)[/tex].
Put the value of g(x) in [tex]f\left(g\left(x\right)\right)[/tex].
[tex]f\left(g\left(x\right)\right)=f(x-7)[/tex] ....(1)
Now, put x=x-7 in [tex]\:f\left(x\right)=\sqrt{3x-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3(x-7)-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3x-21-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3x-23}[/tex]
From equation 1.
[tex]f\left(g\left(x\right)\right)=\:f\left(x-7\right)= \sqrt{3x-23}[/tex]
The domain of the function is the set of input values for which a function is defined.
Here, the value of [tex]3x-23[/tex] should be greater or equal to 0 as the square root of a negative number is not real.
Domain= [tex]3x-23\geq0[/tex]
[tex]x\geq\frac{23}{3}[/tex]
The value of x is all real number greater than [tex]\frac{23}{3}[/tex].
Hence, the interval notation for the domain is [tex][\frac{23}{3},\infty ][/tex].

Some eighth-grade students want to raise at least $300 for a field trip by selling popcorn and fruit bars. The chart below shows the amount of profit they will make on each sale. If they sell exactly 500 fruit bars, how many boxes of popcorn will they need to sell to make a total of $300? 30 cents fruit bars. 60 cents box of popcorn
Answers
popcorn = 60 cts
fruitbars = 30 cts
.
they sold 500 fruit bars = 500 x 0.30 = 150
.
(300 - 150)/0.6 = 150/0.6 = 250 this is how many popcorn they need to sell
The total number of popcorn boxes is given by the equation
A = 250 boxes
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 number of boxes of popcorn be A
Now , the equation will be
Let the cost of one fruit bar = $ 0.30
Let the cost of one popcorn box = $ 0.60
The amount to be raised = $ 300
The number of fruit bars sold = 500
So , the cost of 500 fruit bars = 500 x cost of one fruit bar
Substituting the values in the equation , we get
The cost of 500 fruit bars = 500 x 0.30
The cost of 500 fruit bars = $ 150
Now , the remaining amount to be raised = 300 - 150
The remaining amount to be raised = $ 150
The number of boxes of popcorn A = remaining amount to be raised / cost of one popcorn box
Substituting the values in the equation , we get
The number of boxes of popcorn A = 150 / 0.60
The number of boxes of popcorn A = 250 boxes
Therefore , the value of A is 250 boxes
Hence , the number of boxes is 250
