Find the equation of a line that passes through points A and B.

mars1129 [50]

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)

m = = = 2, thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation.

Using B(2, 3), then

3 = 4 + c ⇒ c = 3 - 4 = - 1

y = 2x - 1 ← equation of line

The area of a right triangle is 270 m². The height of the right triangle is 15 m.

dimaraw [331]

The area of a triangle is calculated by the expression given as:

Area = bh/2

where b is the base and h is the height.

We calculate as follows:

270 = b (15) / 2
b = 36

<span>hypotenuse = sqrt ( 15^2 + 36^2 ) = 39</span>

Which expressions are equivalent to the one below? check all that apply. log(10^3)

Mademuasel [1]

Answer:

They are a and b.

Step-by-step explanation:

We have got logarithms to the base 10 here.

We know that log 10^3 = 3 log 10 ( by the law of logarithms).

Also log 10 = 1 ( by definition) so log 10^3 = 3 log 10 = 3.
