Y=x
You exclude the y-intercept because it has a value of zero. Therefore you would right an equation that passes through point (0,0) as y=x or y=x+0.

3) John has decided to invest his $20,000 in two saving accounts. He decides to invest some of it at 4.5% annual interest and th
Elza [17]

The amount he invested in the account that yields 4.5% interest is $7,500.

The amount he invested in the account that yields 2.5% interest is $12,500.

<h3>What is the system of equations that represent the question?</h3>

a + b = $20,000 equation 1

0.045a + 0.025b = $750 equation 2

Where:

a = amount he invested in the account that yields 4.5% interest

b = amount he invested in the account that yields 2.5% interest

<h3>How much was invested in the account that yields 4.5% interest?</h3>

Multiply equation 1 by 0.025

0.025a + 0.025b = 500 equation 3

Subtract equation 3 from 2

250 = 0.02a

a = 12,500

<h3>How much was invested in the account that yields 4.5% interest?</h3>

Subtract 12,500 from 20,000

20,000 - 12,500 = $7,500

How to do this question I am having a problem trying to do it
nika2105 [10]
Hey there :)

We need to use trigonometry here
Given is the angle   = 30°
And one side           = 26
With a missing side =  x

The missing side is the opposite of the given angle, we have the adjacent but we don't know the value of the hypotenuse, so we need to use Tangent

Tan α = \frac{opposite}{adjacent}
tan 30 = \frac{x}{26}
26tan(30) = x
x = 15
