Mathematics
1 answer:
KIM [24]3 years ago
4 0

Answer:

y - 1 = 2(x - 2)

General Formulas and Concepts:

<u>Algebra I</u>

Point-Slope Form: y - y₁ = m(x - x₁)

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Slope <em>m</em> = 2

Point (2, 1)

<u>Step 2: Write Equation</u>

  1. Substitute in variables:                       y - 1 = 2(x - 2)

What is the difrence between domain and range
Georgia [21]

Answer:

Domain is the set of all possible input values is any relation. It means the output value in a function depends upon each member of domain. Domain value vary in different mathematical problems and depends upon the function for which is it solved. If we talk about cosine, then domain is the set of all possible real numbers either above the 0 value or below the 0 value, it could also be 0. While for square root, the domain value could not be less than 0, it should be minimum 0 or above 0. In other words, you can say that domain of square root is always 0 or positive value. For complex and real equations, the domain value is a subset of complex or real vector space. If we want to solve a partially differential equation for finding the value of domain, then your answer should lie within three dimensional space of Euclidean geometry.

Find the value of x. Round the length to the nearest tenth. The diagram is not drawn to scale.
Gekata [30.6K]

Answer:

x ≈ 2879.4 m

Step-by-step explanation:

Measure of ∠DAC = 10°

Measure of ∠DAB = 90°

Measure of ∠BAC = 90° - 10° = 80°

By applying cosine rule in ΔABC,

cos(80°) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

              = \frac{AB}{AC}

0.17365 = \frac{500}{x}

x = \frac{500}{0.17365}

x = 2879.36

x ≈ 2879.4 m

Question 1 i need help on
ladessa [460]

The actual distance between Bixby and Coyle is 105 miles which can be represented by 7 cm.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

60 miles = 4 cm

Hence:

7 cm = 7 cm * (60 miles)/(4 cm)  = 105 miles

The actual distance between Bixby and Coyle is 105 miles which can be represented by 7 cm.

What is the answer for 3r=10+5 when r=10
katen-ka-za [31]

Answer:

Step-by-step explanation:

What is the VALUE OF 3r=10+5 when r=10?

substitute 10 for r in 3r=10+5.  We get:

3(10) = 10 + 5, or 30 = 15.  This equation is FALSE when r = 10.

You could solve the equation for r, however:

3r=10+5 becomes 3r = 15, and so r = 5.  5 is a solution; 10 is not a solution.
