compare and contrast between x-intercept and y-intercept

Answers

Answer:

"The x-intercept is the point at which the graph crosses the x-axis... ...The y-intercept is the point at which the graph crosses the y-axis." (Lumen)

The x-intercept is on the horizontal axis while the y-intercept is vertical axis. Aside from that they are practically the same and serve the same purpose while graphing, they just go in differing positions.

The intercepts of a graph are points at which the graph crosses the axes. The x-intercept is the point at which the graph crosses the x-axis. ... The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero.

Can someone help me with these questions.

Answers

Answer:

C ( x = 2 (multiplicity of 2), x = -2, x = -4)

A ( x = 5 (crosses), x = -3 (touches))

Step-by-step explanation:

Here are a couple of rules that helped me come to these answers.

1. When finding a zero, you flip the value inside of the parenthesis. For example (x + 2) would have the zero of x = -2.

2.The multiplicity of something is how many times the same zero is there. It is the exponent outside of the equation. For the first question, the (x - 2) has an exponent of 2, thus it has the multiplicity of 2.

3. The multiplicity determines whether the line just touches (or "bounces" off) the x axis or crosses the x axis. If the multiplicity is odd, it crosses the axis. If the multiplicity is even, it just touches the axis. A good way to remember this is with linear and quadratic equations. A linear is commonly know as only having an exponent of 1 (an odd) number and would cross the x axis. A quadratic equation has an exponent of two (an even number) so the line "bounces" on a graph.

In a group of 150 people, 39 of them wear glasses. What is the probability of randomly selecting a person who does not wear glasses?

A. 111/150
B. 39/111
C. 111/189
D. 189/150
E. 39/150

Answers

Answer:

A. 111/150

Step-by-step explanation:

Because we know that 39 people out of the 150 in the group wear glasses, we need to subtract that from the total. This gives us 111 people that don't wear glasses.

Therefore, the probability of choosing someone not wearing glasses is 111/150.

Parallelograms PQRS and QRTU are standing on
the same base QR and between the same parallel
lines PT and QR. Prove that the area of
parallelograms PQRS and QRTU are equal.​

Answers

Uk what? Its most likely in your textbook lol

Parallelograms PQRS and QRTU have the same base QR and height. it proves that areas are equal as base × height remains constant.

To prove that the area of parallelograms PQRS and QRTU are equal,

Use the concept that parallelograms with the same base and between the same parallel lines have equal areas.

Parallelograms PQRS and QRTU

Same base QR

Between the same parallel lines PT and QR

Proof,

Draw a diagram with parallelograms PQRS and QRTU sharing the common base QR and being situated between parallel lines PT and QR.

Since PQRS and QRTU share the same base QR and are between the same parallel lines PT and QR, their heights (perpendicular distances from base QR) are equal.

Let's call this height 'h'.

The area of a parallelogram is given by the formula:

Area = base × height.

For PQRS, its area would be: Area of PQRS = QR × h.

For QRTU, its area would be: Area of QRTU = QR × h.

Since both parallelograms have the same base 'QR' and the same height 'h', their areas are equal.

Therefore, it is proved that the area of parallelograms PQRS and QRTU are equal.
