The lines are parallel bc if you change -10x+y=4 into y=10x+4 they will have the same slope of m=10x

Solve the second equation for y
-10x+y=4
y=10x+4

so we have the 2lines
y=10x-2
y=10x+4

both are written in slope intercept form do the coefficient of x is there slope. since both slopes are the same, namely 10, the two lines are parallel

A data analyst has spreadsheets numbered
algol [13]

Answer:

\frac{2}{9}

Step-by-step explanation:

Express in the form 1:n<br> 3:12
Troyanec [42]

Answer:

1:4

Step-by-step explanation:

Given

3: 12

To express in the form 1:n

Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3

3:12

= 3/3:12/3

= 1:4

Comparing with 1:n, it is safe to say that n = 4

MY BRAIN IS DEAD! PLS HELP MEH ITS THE LAST ONE! TYSM! Time taken for 6 people to build a house is 30 days. How many days will i
iren2701 [21]

Answer:

2 people will take 90 days to complete the same house

Step-by-step explanation:

<u><em>Given:</em></u>

T1 = 30 days

P1 = 6

T2 = x

P2 = 2

This is an inverse proportion because if there are more people, less time will be taken to complete the house and vice versa.

<u><em>So, We'll write it in the order of :</em></u>

=> T1:T2 = P2:P1

=> 30:x = 2:6

<u><em>Writing in fraction form</em></u>

=> \frac{30}{x} = \frac{2}{6}

<em>Cross Multiplying</em>

=> 2x = 180

<em>Dividing both sides by 2</em>

=> <u><em>x = 90 days</em></u>

So, <u><em>2 people will take 90 days to complete the same house</em></u>
