HELP ASAP !! Which equation is equivalent to the equation 3x-4y=48?
A. y=-3/4×-24
B. y=-3/4×-18
C. y=4/3×+18
D. y=3/4×-12
Answers
Answer:
D. y = 3/4x - 12Step-by-step explanation:
3x-4y=48-4y = -3x + 48y = -3/-4x + 48/-4y = 3/4x - 12Correct one is D
If x=4 y=-3 and z =5 find the value of 5y +2x-z
Answers
All you have to do is substitute the variables for their values and solve.
Hope this helps!
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

2x+7y=28
7x-2y=4
Answer, please.
Answers
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.

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.
Answers
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

round 967 to ? round to the nearest hundred
Answers
Answer:
967 is 1000.
Step-by-step explanation:
0-4 stays the same, 5-9 goes up one. The number after the one that needs to be rounded is the one you should worry about. For 967, 6 is the number after the primary number that needs to be rounded to the hundred. Since 6 is between 5-9, 6 goes up one and changes 967 into 1000.

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
Answers
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.

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
