Answer:

The statement is true

see the explanation

Step-by-step explanation:

we have the proportion

$\frac{a}{b}=\frac{c}{d}$

we know that

To solve the proportion multiply in cross

$(a)(d)=(b)(c)$

$ad=bc$

therefore

The statement is true

Which statement best describes the equation y = 3 - 4x?

Ronch [10]

The correct answer is C. A linear equation is written in y=mx+b, which this equation can be. y=3-4x is the same as y=-4x+3, which is a linear function.

Diagram of two triangles

The two triangles are similar because they are both right triangles, meaning that one angle is 90° and the other two are acute (less than 90°).

The diagram on the left is missing its hypotenuse - the variable c. The hypotenuse is opposite of the right angle. The diagram on the right side is missing one of its legs.

Note: The hypotenuse is the longest side of a right triangle.

Word Problen

The legs are 21 blocks and 20 blocks because they are by the right angle. Use the Pythagorean theorem to find the diagonal path's length, which is the hypotenuse.

${a}^{2} + {b}^{2} = {c}^{2}$
