The sum of a certain number and 8 is 23. What is the number?
equation:

n =

Answers

Answer 1

Answer: So mathematically, it's n + 8 = 23

Just subtract both sides by 8 and you will get n = 15

Answer 2

Answer: n + 8 = 23
n = 15 (subtract 8 from both sides).

There you go.

The graph of a line passes through two given points, as shown on the graph below. What is the equation of the line written in general form?

Answers

The line drops 5 units as it proceeds forward 5 units.
Its slope is (-5) / 5 = -1

The line crosses the y-axis at the point y=5 .

The general form of the line's equation is: y = - x + 5 .

Answer:

x+y-5=0

Step-by-step explanation:

This is in general form.

In triangle ABC , angle A is a right angle and angle B = 45. If AB = 19 feet, what is BC?

Answers

If angle A measure 90° and angle B is 45° , that leaves 45° for angle C. (90 + 45 + 45 = 180)
If both non right angles are 45° we have an isosceles right triangle and AC is also 19 feet.

So now we can use the Pythagorean theorem to find the missing side.

a² + b² = c² and we are looking for BC - the hypotenuse of the triangle

19² +19² = c² 361+361 = c² 722= c² and c=√722 or about 26.87

Final answer:

In triangle ABC, if angle A is a right angle and angle B is 45 degrees, it is a 45-45-90 special right triangle. Given that AB = 19 feet, BC will also be 19 feet due to the properties of 45-45-90 triangles.

Explanation:

In triangle ABC, since angle A is a right angle and angle B is 45 degrees, we are dealing with a 45-45-90 triangle which is a special right triangle. In a 45-45-90 triangle, the sides are in the ratio of 1:1:√2.

Given that AB = 19 feet, because of the special properties of a 45-45-90 triangle, we know that in these triangles, the two legs are of equal length. So the length of BC, which is the other leg of the triangle will also be 19 feet.
