What is the slope of the line represented by the following equation? 4x−y+3=0
The slope of the line which is represented by the provided equation 4x-y+3=0 is the number 4.
What is the slope of a line?The slope of a line is the difference in the height of the y coordinates and the difference in the width of the coordinates. It describes the direction of the line.
The standard form of the equation of a line can be given as,
y=mx+c
Here, c is the y intercept of the line and m is the slope of the line.
The equation of the line is given as,
4x-y+3=0
Rewrite the equation in the standard form as,
4x-y+3=0
4x+3=y
y=4x+3
Compare it with standard equation we get,
m=4
c=3
Thus, the slope of the line which is represented by the provided equation 4x-y+3=0 is the number 4.

The table shows the cumulative number of minutes Alice practices clarinet for the first part of the school year. The values will be graphed on the given coordinate plane. Which is the most appropriate choice of origin and scale for this graph?
The option (C) x-axis, scale: 1 unit = 1 week and y-axis, scale: 1 unit = 150 minutes with origin (0 weeks, 0 minutes) is correct.
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
As we can see in the table, data is given, we can plot it in the graph by using the scale factor.
On the x-axis, scale: 1 unit = 1 week
On the y-axis, scale: 1 unit = 150 minutes
On the y-axis, 2 units = 300 minutes
On the y-axis, 3 units = 450 minutes
Thus, the option (C) x-axis, scale: 1 unit = 1 week and y-axis, scale: 1 unit = 150 minutes with origin (0 weeks, 0 minutes) is correct.

The inequalities are x + y < 5000 and 0.10x + 0.15y ≤ $450 which shows each month, you want to only spend up to $450 and use less than 5,000 minutes on both of the devices.
What is inequality?Inequality is defined as a mathematical expression in which both sides are not equal and have mathematical signs that are either less than or greater than.
Let's suppose the total minutes of uses for cell phone is x
and total minutes of uses of for tablet is y
Cell phone cost $0.10 each minute and tablet cost $0.15 each minute.
Then total minutes will be:
x + y < 5000 (as it is given that the time will be less than 5,000 minutes on both of the devices)
And total cost = $450
0.10x + 0.15y ≤ $450
Thus, the inequalities are x + y < 5000 and 0.10x + 0.15y ≤ $450 which shows each month, you want to only spend up to $450 and use less than 5,000 minutes on both of the devices.

Answer:
1/15 or 0.0666.. repeating
Step-by-step explanation:
1. Group all a terms on the left side of the equation
Add a to both sides
[tex]46a+\frac{5}{3}+a=\frac{24}{5}-a+a[/tex]
Group like terms:
[tex]46a+a+\frac{5}{3}=\frac{24}{5}-a+a[/tex]
Simplify the arithmetic:
[tex]47a+\frac{5}{3}=\frac{24}{5}-a+a[/tex]
Group like terms:
[tex]47a+\frac{5}{3}=-a+a+\frac{24}{5}[/tex]
Simplify the arithmetic:
[tex]47a+\frac{5}{3}=\frac{24}{5}[/tex]
2. Group all constants on the right side of the equation
[tex]47a+\frac{5}{3}=\frac{24}{5}[/tex]
Subtract [tex]\frac{5}{3}[/tex] from both sides:
[tex]47a+\frac{5}{3}-\frac{5}{3}=\frac{24}{5}-\frac{5}{3}[/tex]
Combine the fractions:
[tex]47a+\frac{5-5}{3}=\frac{24}{5}-\frac{5}{3}[/tex]
Combine the numerators:
[tex]47a+\frac{0}{3}=\frac{24}{5}-\frac{5}{3}[/tex]
Reduce the zero numerator:
[tex]47a+0=\frac{24}{5}-\frac{5}{3}[/tex]
Simplify the arithmetic:
[tex]47a=\frac{24}{5}-\frac{5}{3}[/tex]
Find the lowest common denominator:
[tex]47a=\frac{24\cdot 3}{5\cdot 3}+\frac{-5\cdot 5}{3\cdot 5}[/tex]
Multiply the denominators:
[tex]47a=\frac{24\cdot 3}{15}+\frac{-5\cdot 5}{15}[/tex]
Multiply the numerators:
[tex]47a=\frac{72}{15}+\frac{-25}{15}[/tex]
Combine the fractions:
[tex]47a=\frac{72-25}{15}[/tex]
Combine the numerators:
[tex]47a=\frac{47}{15}[/tex]
3. Isolate the a
[tex]47a=\frac{47}{15}[/tex]
Divide both sides by 47:
[tex]\frac{47a}{47}=\frac{\frac{47}{15}}{47}[/tex]
Simplify the division:
[tex]a=\frac{47}{15\cdot 47}[/tex]

Identify the axis of symmetry, vertex, and y intercept of y=-6x^2+12x-8
Answer:
See below for answers and explanations (with attached graph)
Step-by-step explanation:
It helps to transform the equation into vertex form by completing the square because it tells us a lot about the characteristics of the parabola:
[tex]\displaystyle y=-6x^2+12x-8\\\\y=-6\biggr(x^2-2x+\frac{4}{3}\biggr)\\\\y-6\biggr(-\frac{1}{3}\biggr) =-6\biggr(x^2-2x+\frac{4}{3}-\frac{1}{3}\biggr)\\\\y+2=-6(x^2-2x+1)\\\\y+2=-6(x-1)^2\\\\y=-6(x-1)^2-2[/tex]
Since vertex form is [tex]y=a(x-h)^2+k[/tex], we identify the vertex to be [tex](h,k)\rightarrow(1,-2)[/tex] and the axis of symmetry to be [tex]x=h\rightarrow x=1[/tex]. The y-intercept can be found by setting [tex]x=0[/tex] and evaluating:
[tex]y=-6(x-1)^2-2\\\\y=-6(0-1)^2-2\\\\y=-6(-1)^2-2\\\\y=-6(1)-2\\\\y=-6-2\\\\y=-8[/tex]
Hence, the y-intercept of the parabola is [tex]y=-8[/tex], or [tex](0,-8)[/tex] as an ordered pair.

Amir drove from Jerusalem to the lowest place on Earth, the Dead Sea. His altitude relative to sea level (in meters) as a function of time (in minutes) is graphed. How fast did Amir descend?
The equation for the flowing rate of aamir is as follows y = -12x +360
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
First of all let's write the slope-intercept form of the equation of a line, which is:
y = mx + c
So we just need to find to solve this problem.
Moreover, this problem tells us that Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12 meters per minute. So this rate is the slope of the line, that is:
Negative slope because Amir is descending. So:
y = - 12x + b
To find, we need to use the information that tells us that he was at sea level after 30 minutes of driving, so this can be written as the point. Therefore, substituting this point into our equation:
y = -12x + b
0 = -12(30) + b
b = 360
Finally, the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is:
y = -12x +360

As you can see, the "H" is going to be painted brick red in the center of a rectangular beige background. This means the distance from the "H" to the top of the picture will be the same as the distance from the "H" to the bottom of the picture. Similarly, the distance from the "H" to the left side of the picture will be the same as the distance from the "H" to the right side of the picture. Finally, each segment of the "H" will have the same width.

The triangles are not similar
Step-by-step explanation:
You can make a ratio with the corresponding sides of the triangles. When triangles are similar, the ratios are equal.
These will be:

Now, to substitute the numbers and check whether the ratios are equal:
3/8 = 2/5
Already, we see that these ratios are not equal, therefore the two triangles aren't similar.
