Answer: y = -x + 7

Step-by-step explanation:

The slope is $\frac{5-6}{2-1}=-1$ , so we know the equation is of the form $y=-x+b$ .

Substituting in the coordinates (1,6) to find b,

$6=-1+b\\\\b=7$

Thus, the equation is y = -x + 7

Fred and Ben each ran laps around the track. Fred completed his run in 16 minutes. Ben completed his run in 3/4 of the amount of

m_a_m_a [10]

Answer:

Time required by Ben was 12 minutes.

Step-by-step explanation:

Given:

Time Required for Fred = 16 mins

Ben completed his run in 3/4 of the amount of time of Freds run.

We need to find the time required by Ben.

Now Given that;

Ben completed his run in 3/4 of the amount of time of Freds run.

It means that time required by Ben is equal to 3/4 times time required by Fred.

Time required by Ben = $\frac{3}{4}\times Freds \ run$

Time required by Ben = $\frac{3}{4}\times 16 = 12\ mins$

Hence Time required by Ben was 12 minutes.

Write an algebraic expression to represent the area of the triangle (Area = 1/2 ×base ×height) given that the length is 6 inches

shusha [124]

The expression for area of triangle is 1/2x² + 3x.

<h3>What is Algebra?</h3>

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Area = 1/2 × base × height

and, length is 6 inches greater than the height.

let the height of the triangle is x

length of triangle = x + 6

So, The Area of triangle

= 1/2 x base x height

= 1/2(x)(x+ 6)

= 1/2x² + 3x

Hence, the expression for area of triangle is 1/2x² + 3x.
