Determine whether the lines given are parallel, perpendicular, or neither
2x+7y=28
7x-2y=4
Answer, please.
Answer:
The answer is that these equations are perpendicular
Step-by-step explanation:
They have the different slopes and y-intercepts
y = -2/7x + 4
y = 7/2x - 2
pls mark me as brainliest
The given lines 2x + 7y = 28 and 7x - 2y = 4 are perpendicular to each other.
Used the concept of slope of two lines that states that,
The relation between the slope of two perpendicular lines m₁ and m₂ is,
[tex]m_1 \times m_2 = - 1[/tex]
And, the relation between the slope of two parallel lines m₁ and m₂ is,
[tex]m_1= m_2[/tex]
Given that,
The equation of lines is,
2x + 7y = 28
And, 7x - 2y = 4
Now change the equation of a line in slope-intercept form as
[tex]2x + 7y = 28[/tex]
[tex]7y = 28 - 2y[/tex]
Divide both sides by 7,
[tex]y = \dfrac{- 2}{7}x + 4[/tex]
So, the slope of the line = - 2/7
From the second equation,
[tex]7x - 2y = 4[/tex]
[tex]7x - 4 = 2y[/tex]
[tex]2y = 7x - 4[/tex]
Divide both sides by 2,
[tex]y = \dfrac{7}{2}x - 2[/tex]
So, the slope of the line = 7/2
Hence, the relation between both of the slopes is,
[tex]\dfrac{- 2}{7} \times \dfrac{7}{2} = - 1[/tex]
Therefore, both of the given lines are perpendicular.

-2(-5x+5) - 3x + 4= -34 solve for x
Answer:
x = -4
Step-by-step explanation:
-2(-5x+5) - 3x + 4= -34
10x - 10 -3x + 4 = -34
7x - 6 = -34
+6 + 6
7x = -28
x = -4
Answer:
x = -4
Step-by-step explanation:
- distribute -2 by multiplying it with the paranthesis
-2*(-5x) + -2*(5) - 3x + 4 = -34
10x - 10 - 3x + 4 + 34 = 0
7x + 28 = 0
x = -28/7
x = -4

Item 15 Your math class is collecting canned food for a local food drive. The goal is to collect at least 130 cans but no more than 250 cans due to space limitations. There are 24 students in your math class and your teacher has promised to bring in 10 cans. Select which inequalities represent the possible numbers $n$ of cans that each student should bring in.
For this case, the first thing we must do is define variables.
We have then:
n: number of cans that each student must bring
We know that:
The teacher will bring 5 cans
There are 20 students in the class
At least 105 cans must be brought, but no more than 205 cans
Therefore the inequation of the problem is given by:
Answer:
105 < 20n + 5 < 205
the possible numbers n of cans that each student should bring in is:
105 < 20n + 5 < 205

2. 5/6
3. 213
B. Write the terminating decimal as fraction or mixed number i
simplest form.
1. 0.6
2. 1.25
3. 0.125
pleaseeee answer this
Answer:
Question A:
1. 1/2 = 0.5 (Terminating)
2. 5/6 = 0.833333.. (Repeating)
3. 21/3 = 1.6666666.. (Repeating)
Question B:
1. 0.6 = 3/5
2. 1.25 = 5/4 = 1 1/4
3. 0.125 = 1/8
Step-by-step explanation:
A. Write the fraction or mixed number as a terminating or repeating decimal.
In order to convert a fraction into decimal, the numerator has to be divided by denominator.
1. 1/2
The answer is: 0.5 which is a terminating decimal.
2. 5/6
The answer is: 0.833333.. which is a repeating decimal.
3. 2 1/3 (assuming the question is this)
[tex]2\frac{1}{3} = \frac{7}{6} = 1.6666666..[/tex]
The answer is 1.6666666.. which is a repeating decimal.
B. Write the terminating decimal as fraction or mixed number i n simplest form.
1. 0.6
[tex]0.6 = \frac{6}{10} = \frac{3}{5}[/tex]
2. 1.25
[tex]1.25 = \frac{125}{100} = \frac{5}{4} = 1\frac{1}{4}[/tex]
3. 0.125
[tex]0.125 = \frac{125}{1000} = \frac{5}{40} = \frac{1}{8}[/tex]
Hence,
Question A:
1. 1/2 = 0.5 (Terminating)
2. 5/6 = 0.833333.. (Repeating)
3. 21/3 = 1.6666666.. (Repeating)
Question B:
1. 0.6 = 3/5
2. 1.25 = 5/4 = 1 1/4
3. 0.125 = 1/8

St boniface Hospital raises funds for research through its annual dinner and Gala event.For this event 353 tickets are available for purchase in total.A single ticket is sold for $92 and a family ticket is sold $122 this year the event sold out with sales of 39946 as the marketing manager ,wants to know how many family tickets were purchased
Given:
Total number of tickets = 353
Single ticket = $92
Family ticket = $122
Total sales = $39946
To find:
The number of family tickets.
Solution:
Let x be the number of single tickets and y be the number of family tickets.
Total tickets: [tex]x+y=353[/tex] ...(i)
Total sales: [tex]92x+122y=39946[/tex] ...(ii)
Multiply (i) by 92 and subtract the result from (ii).
[tex]92x+122y-92(x+y)=39946-92(353)[/tex]
[tex]92x+122y-92x-92y=39946-32476[/tex]
[tex]30y=7470[/tex]
Divide both sides by 30.
[tex]y=\dfrac{7470}{30}[/tex]
[tex]y=249[/tex]
Therefore, the number of family tickets is 249.

If x=4 y=-3 and z =5 find the value of 5y +2x-z
Answer:-12
Step-by-step explanation:
So if the equation is 5y+2x-z and the substitutions are x=4 y=-3 z=5 , all you have to do is replace each variable with its given numbers. Like so
5(-3)+2(4)-5
Now what you have to do is simplify
Negative times a positive is a negative
Negative times a negative is a positive
Positive times a positive is a positive
So....
-15+8-5
-20+8
-12
This is a simple substitution problem. Remember the basics of negatives and positives! Than you will be just fine! :D

A group of friends were working on a student film. They spent all their budget on equipment and props. They spent $870 on equipment, and 13% of the total budget on props. What was the total budget for their student film?
Answer:
$1000
Step-by-step explanation:
Let us represent the total budget of the film as: x
The amount spent on equipment = $870
The amount spent on props = 13% of x
Total budget = Amount spent on equipment + Amount spent on props
Hence
x = $870 + 13% of x
x = 870 + 0.13
Collect like terms
x - 0.13 = 870
0.87x = 870
Divide both sides by 0.86
x = 870/0.87
x = $1000
Therefore, the total budget for their student film is $1000
Answer:
the answer is 1000

There are 42 dogs at the local shelter. Which equation can be used to determine how many dogs the shelter can provide for if it is currently at 60% capacity? 42/x=100/60 42/x=40/100 42/60=100/x 60/100=42/x
Answer:
100/60 = 42 / x
Step-by-step explanation:
Given that :
Number of dogs at shelter = 42
Capacity of shelter = 60%
Number of dogs shelter can cater for :
Let number of dogs shelter can cater for = x
60% of 42 = x
(60/100) * 42 = x
60/100 = x / 42
Reciprocal of both sides
100/60 = 42 / x
Answer:
60/100=42/x
