Answer:

1/2

Step-by-step explanation:

A line that is perpendicular to another has an opposite reciprocal slope. In this case, we can see that the slope of the given line is -2, so the perpendicular line would have a slope of 1/2.

Answer:

1/2

Step-by-step explanation:

The slope of a line perpendicular to any given line is the negative reciprocal of the given line's slope:

[tex]m_\perp = \dfrac{1}{m}[/tex]

In this problem, the slope of the given line is [tex]\dfrac{-2}{1}[/tex] (rise over run).

So, to find the slope of a line that is perpendicular to it, we simply flip the given line's slope and change its sign.

[tex]m_\perp = \dfrac{1}{2}[/tex]

So, a line which is perpendicular to the given line would have a slope of 1/2.

The system of equations could be used to find the number of gallons of gas Chris bought at each station is,

B. x + y = 20 and 1.45x + 1.55y = 29.80.

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, Chris stopped for gas twice on a long car trip.

The price of gas at the first station was $1.45 per gallon, and the price of gas at the second station was $1.55 per gallon and filled a total of 20 gallons of gas and cost him a total of $29.80.

Therefore the system of linear equations that represents the context is,

x + y = 20 and 1.45x + 1.55y = 29.80.

The equation is y = 1000 - 10x, where y is the number of blankets sold and x is the price in dollars.

This equation represents the relationship between the number of blankets sold (y) and the price of each blanket (x). The equation starts with the total number of blankets Christina has to sell (1000) and then subtracts 10 for every $1 increase in the price of the blanket. This means that as the price of the blanket increases, the number of blankets sold will decrease by 10 for every $1 increase. For example, if Christina charges $50 for a blanket, the number of blankets sold would be 500 (1000 - (10x50)).

The graph that shows the function h(x) = -x] which is a transformation of the absolute value parent function, f(x) = [x] is Option C.

The graph of the function h(x) = -x] is the reflection of the graph of f(x) = [x] about the x-axis. The graph of f(x) is piecewise defined as follows:

The graph of h(x) will have the same shape as f(x), but with all the y-values negated, so:

The graph of h(x) will thus be a downward-facing step function, with steps at x = 0, moving from -x to x as x moves from negative to non-negative values. Thus, Option C is correct.

The third side of a triangle can be found using the Pythagorean Theorem.

This states that the sum of the squares of the two shorter sides of a triangle must equal the square of the longest side (the hypotenuse).

Let's say you have a triangle with sides a, b, and c, where c is the longest side. To find c, you can use the following formula:

c = √(a2 + b2)

For example, if you have a triangle with sides a = 4 and b = 5, then c = √(42 + 52) = √41 = 6.4. Therefore, the third side of the triangle is 6.4.

To calculate this using steps, you would first square the two shorter sides of the triangle:

a2 = 4 x 4 = 16

b2 = 5 x 5 = 25

Then, add the two squares together:

16 + 25 = 41

Finally, take the square root of the sum to find the length of the third side:

√41 = 6.4

Therefore, the third side of the triangle is 6.4.

The reflection that maps ST onto itself is a reflection in the line y = -7.

What is the line of symmetry?

Reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry is symmetry with respect to a reflection. That is, a figure which does not change upon undergoing a reflection has reflectional symmetry. In 2D there is a line/axis of symmetry, in 3D a plane of symmetry.

A reflection maps a geometric figure onto itself by "flipping" it across a line of symmetry. In this case, the reflection maps ST onto itself, so the line of symmetry must be a line that ST is reflected across.

To find this line, we can look at the two given vertices of ST, S(-7, 1) and T(-7, 5).

We can see that these points have the same x-coordinate (-7), which means that the line of symmetry must be a vertical line passing through the x-coordinate of -7.

Therefore, the reflection that maps ST onto itself is a reflection in the line y = -7.
