Is this correct or no
iris [78.8K]

Answer:

Incorrect

Step-by-step explanation:

The correct answer is A.

The slope-intercept form is y-y₁=m(x-x₁)

The problem with B is that if you take out the coordinates for x₁ and y₁, you get the coordinates (1,4). This coordinate does not land on the line.

The coordinates for A is (-1,4). This point does land on the line.

Safe or not, he made it up the tower, since he is, after all, a warrior. The ransom note
Alona [7]

The width of the river = 60m and so Zachary will be able to swim the river without getting tired.

<h3>What is Proportion ?</h3>

When two ratios are equal , the ratio are said to be in proportion.

As given in the question ,

the width of the river has to be determined

Looking at the figure , the triangle formed at the side of the river is a right triangle the hypotenuse will be determined from the Pythagoras theorem

20² +24² = y²

y = 21.2 m

As the corresponding sides are proportional

31.2 : z = 20:50

z = 78.1

The value of the width of the river will be determined by the Pythagoras Theorem

78.1² = 50² + x²

x = 60m

the width of the river = 60m

Therefore Zachary will be able to swim the river without getting tired.
