The sum of Paul’s and Sam’s ages is 4 and the difference between their ages is 0. Two equations to model this situation are x + y = 4 and x - y = 0. The solution represents both of their ages. What quadrant does the solution lie in?

A.) IV
B.) II
C.) III
D.) I

Answers

Answer:

D.) |.

Step-by-step explanation:

x + y = 4

x - y = 0      Adding:

2x + y - y = 4

2x = 4

x = 2

and y = 4 - 2 = 2.

The point (2, 2) is in quadrant |

A line with a slope of -2 is written in the form y=mx+b.
what is the value of b If the line passes through the point (5,-7)?​

Answers

Answer:

b = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Here m = - 2 , then

y = - 2x + b ← is the partial equation

To find b substitute (5, - 7 ) into the partial equation

- 7 = - 10 + b ⇒ b = - 7 + 10 = 3

What is the value for the missing angle ??


Answers

Answer: 9 inches.
Do the pythagorean theorem to find your answer.
Formula: a^2 + b^2 = c2
12 = b
15 = c
a^2 + 12^2 = 15^2
Simplify the equation
a^2 + 144 = 225
Subtract 144 on both sides.
a^2 = 81
Square root of 81 is 9.

Use a Pythagorean Triple to find x.

Answers

Answer:

x = 51

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )

x = [tex]\sqrt{2601}[/tex] = 51

Answer:

x = 51.

Step-by-step explanation:

The triple you require is 17-15-8

We have x-45-24

- that is three times each number in the triple.

So x = 3*17 = 51.
