X+4y<4 linear inequalities
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]x + 4y < 4[/tex]
The question is incomplete, as what is to be done is not stated.
However, possible sub-questions could be to determine the slope and the y-intercept for the boundary line.
To calculate slope, we have:
[tex]x + 4y < 4[/tex]
Solve for 4y
[tex]4y < - x + 4[/tex]
Solve for y
[tex]y < -\frac{x}{4} + \frac{4}{4}[/tex]
[tex]y < -\frac{1}{4}x + 1[/tex]
A linear inequality is represented as:
[tex]y <mx + b[/tex]
Where [tex]m =slope[/tex] and [tex]b = y\ intercept[/tex]
So:
By comparison:
[tex]mx = -\frac{1}{4}x[/tex]
[tex]m = -\frac{1}{4}[/tex]
and
[tex]b = 1[/tex]
So:
[tex]Slope = -\frac{1}{4}[/tex]
[tex]y\ intercept = 1[/tex]

Answers
Answer:
X = 3
Step-by-step explanation:
Answer:
= 2
Step-by-step explanation:5x+15=75-25x
We move all terms to the left:
5x+15-(75-25x)=0
We add all the numbers together, and all the variables
5x-(-25x+75)+15=0
We get rid of parentheses
5x+25x-75+15=0
We add all the numbers together, and all the variables
30x-60=0
We move all terms containing x to the left, all other terms to the right
30x=60
x=60/30
x=2

If a student answers 42 out of 48
questions correctly on a quiz, what
percentage of questions did she
answer correctly?
Answers
Answer:
She answered 87.5% correctly.
Step-by-step explanation:
100÷48=2.083
2.083×42=87.5
The percentage of student answered correctly is 87.5%.
What is percentage?A percentage, a relative value indicating hundredth parts of any quantity.
How to find the prcentage of a number of quantity?The following formula is a common strategy to calculate a percentage:
Determine the total amount of what you want to find a percentage.Divide the number to determine the percentage.Multiply the value by 100.According to the given question.
Total number of questions = 48
Total number of questions which are answered correclty by a student = 42
Therefore, the percentage of question the students answered correctly is given by
[tex]Percentage = \frac{total \ correctly \ answered\ questions}{Toal\ number \ of\ questions\ } \times 100[/tex]
[tex]\implies percentage = \frac{42}{48} \times 100[/tex]
[tex]\implies percentage = 0.875\times 100[/tex]
[tex]\implies percentage = 87.5\%[/tex]
Hence, the percentage of student answered correctly is 87.5%.

What would 'x' be in the equation -3(x-2)=6?
Answers
Answer:
[tex]\boxed {\boxed {\sf x=0}}[/tex]
Step-by-step explanation:
To solve this equation, we must isolate the variable (x) using inverse operations.
[tex]-3(x-2)=6[/tex]
x-2 is being multiplied by -3. The inverse operation of multiplication is division, so we divide both sides by -3.
[tex]-3(x-2)/-3= 6/-3\\(x-2)=6 /-3 \\(x-2)= -2[/tex]
2 is being subtracted from x. The inverse operation of subtraction is addition, so add 2 to both sides of the equation.
[tex]x-2+2=-2+2\\x=-2+2\\x=0[/tex]
In this equation, x is equal to 0.

Find the equation of the line which passes through (0, 7) at a gradient of 3.
Answers
Answer:
y = 3x + 7
Step-by-step explanation:
Here, line is passing through the point (0, 7). It's x-coordinate is 0 and y-coordinate is 7
So, y-intercept (b) = 7
Gradient (or slope m) = 3
Equation of line in slope intercept form is given as:
y = mx + b
Plugging m = 3 and b = 7 in the above equation, we find:
y = 3x + 7
This is the required equation of line.

This year, a small business had a total revenue of $14,600. If this is 27% less than their total revenue the previous year, what was their total revenue the previous year?
Answers
Given:
The total revenue of this year = $14,600
This year revenue is 27% less than their total revenue in the previous year.
To find:
The total revenue in the previous year.
Solution:
Let x be the total revenue of the previous year.
This year revenue is 27% less than their total revenue the previous year.
Revenue in this year = Revenue in previous year - 27% of it
[tex]14600=x-\dfrac{27}{100}x[/tex]
[tex]14600=x-0.27x[/tex]
[tex]14600=0.73x[/tex]
Divide both sides by 0.73.
[tex]\dfrac{14600}{0.73}=x[/tex]
[tex]20,000=x[/tex]
Therefore, the total revenue in the previous year is $20,000.
