Write the equation of a line that is perpendicular to y=0.25x-7 and passes through the point (-6,8)
The equation of a line that is perpendicular to y = 0.25x -7 and passing through the point (-6,8) is y = -4x -16.
Explanation:In the mathematical realm, a line that is perpendicular to another has a slope which is the negative reciprocal of the original line's slope. The given equation, y = 0.25x - 7, has a slope of 0.25. Thus, the slope of the perpendicular line would be the negative reciprocal, which is -1/0.25 = -4. Now, a line's equation can be written in the form y = mx + b, where m is the slope and b is the y-intercept. Although we now know our perpendicular line's slope, we still need the y-intercept. To find it, we use the formula b = y - mx, substituting in our known slope (-4) and given point (-6,8). After calculation, b = 8 - (-4*-6) = -16. Therefore, the equation of a line that is perpendicular to y = 0.25x - 7 and passes through the point (-6,8) is y = -4x -16.

If vector u = (5, 3) and vector v = (-1, 4), what is the component form of vector u + v?
So, the component form of vector u + v is (4, 7).
Final answer:
The component form of the sum of vector u = (5, 3) and vector v = (-1, 4) is found by adding corresponding components, yielding the sum vector u + v = (4, 7).
Explanation:
To find the component form of the sum of two vectors, vector u, and vector v, you simply add the corresponding components of each vector. The given vectors are vector u = (5, 3) and vector v = (-1, 4). By adding the x-components (5 and -1) and the y-components (3 and 4), we get the sum of the vectors.
The component form of vector u + vector v is calculated as follows:
Sum of x-components: 5 + (-1) = 4Sum of y-components: 3 + 4 = 7Therefore, the component form of vector u + vector v is (4, 7).

Explain how you can classify shapes, using the distance and slope formula. Provide examples to support your response.
Final answer:
Shapes can be classified using the distance and slope formulas by calculating side lengths and verifying perpendicular or parallel lines, as demonstrated in identifying a rectangle through side equality and perpendicularity.
Explanation:
You can classify shapes by using the distance and slope formulas to understand their geometry, such as identifying parallelograms or triangles with equal sides. The distance formula, √((x2-x1)² + (y2-y1)²), helps calculate the exact length between two points, allowing one to discern if sides are equal and hence contributing to classifying the shape. The slope formula, (y2-y1) / (x2-x1), helps determine the incline or decline between two points, which is essential for identifying parallel or perpendicular lines, thus assisting in shape classification.
For example, to classify a quadrilateral as a rectangle, you could calculate the distance between all points to ensure opposite sides are equal and use the slope formula to ensure adjacent sides are perpendicular by checking if the product of their slopes is -1.
Which of the following shows the graph of a line with a slope of 6/5 and a y intercept of -3?
Answer:
The correct option is 1.
Step-by-step explanation:
It is given that the slope of the line is 6/5 and y intercept is -3. It means the line must be passes through the point (0,-3).
The slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
Substitute m=6/5 and b=-3 in the above equation to find the equation of line.
[tex]y=\frac{6}{5}x+(-3)[/tex]
So, the equation of line is [tex]y=\frac{6}{5}x+(-3)[/tex].
Substitute y=0 in the above equation to find the x-intercept of the line.
[tex]0=\frac{6}{5}x-3[/tex]
Add 3 on both the sides.
[tex]0+3=\frac{6}{5}x-3+3[/tex]
[tex]3=\frac{6}{5}x[/tex]
Multiply both sides by 5.
[tex]15=6x[/tex]
Divide both sides by 6.
[tex]\frac{15}{6}=x[/tex]
[tex]2.5=x[/tex]
The x-intercept of the line is 2.5. It means the line must be passes through the point (2.5,0).
Since only in graph 1, the line passes through the points (0,-3) and (2.5,0), therefore the graph 1 represents the required line and option 1 is correct.
A pharmacist has an 18% alcohol solution. How much of this solution and how much water must be mixed together to make 10 liters of a 12% alcohol solution?
Answer:
[tex]6\frac{2}{3}[/tex] of 18%, [tex]3\frac{1}{3}[/tex] water
Step-by-step explanation:
The 18% solution added to the water is equal to the 10 liters of 12% solution.
Let's say that the amount of 18% solution is x
18% of x = 0.18x
Let's say that the amount of water is 10-x
Because there is no alcohol in water, it will be 0(10-x), or just 0
0.18x + 0 = 10•0.12
0.18x = 1.2
x = [tex]6\frac{2}{3}[/tex]
10 - [tex]6\frac{2}{3}[/tex] = [tex]3\frac{1}{3}[/tex]
To make a 10 liter solution of 12% alcohol, you need to mix 6.67 liters of an 18% alcohol solution with 3.33 liters of water.
Explanation:To make a 12% alcohol solution, we need to mix the 18% alcohol solution with water. Let's assume x liters of the 18% alcohol solution and (10 - x) liters of water.
The amount of alcohol in the 18% solution is 0.18x liters, while the amount in the water is 0 liters. In the final solution, the amount of alcohol is 0.12 * 10 = 1.2 liters.
So, we can set up the equation 0.18x + 0 = 1.2 and solve for x. By solving this equation, we find that x = 6.67 liters. Therefore, 6.67 liters of the 18% alcohol solution and 3.33 liters of water should be mixed to make 10 liters of a 12% alcohol solution.
