Answer:

y= 7/5x or f(x)= 7/5x

Step-by-step explanation:

The x intercept is -5 which as a point is (-5,0)

The y intercept is 7 which as a point is (0,7)

find slope

m=7-0/0-(-5)

m=7/5

2. write equation

(The equation can be written as either y equals or the function of x equals)
y=7/5x
f(x)=7/5x

There are three squares inside the triangle . Find the area of the third triangle with steps , please

pogonyaev

Answer: 49 cm^2

Step-by-step explanation:

The length of the small pink square box will be:

L^2 = 9

L = sqrt( 9 )

L = 3

The length of the big pink square box will be:

L^2 = 16

L = sqrt( 16 )

L = 4

The length of the yellow square box will be:

4 + 3 = 7

The area of the third square box will be

A = 7^2

A = 49 cm^2

Complete the steps to solve the equation. 9 – 4x = 2x 1. Addition property of equality: 9 = 6x 2. Division property of equality:

exis [7]

x = 3/2

Step-by-step explanation:

Given equation is:

$9 - 4x = 2x$

As we have to solve for x, x will be isolated on one side of the equation

So,

1. Addition property of equality

4x will be added on both sides

$9-4x+4x=2x+4x\\9 = 6x$

2. Division property of Equality

Dividing both sides by 6

$\frac{6x}{6}=\frac{9}{6}\\x = \frac{3}{2}$

Hence,

x = 3/2

Write the explicit rule,

meriva

Answer:

$a_{n}$ = 20n + 12

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 52 - 32 = 72 - 52 = 92 - 72 = 20

This indicates the sequence is arithmetic with explicit formula

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 32 and d = 20, thus

$a_{n}$ = 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12
