Janine wants a necklace 45 beads long

seraphim [82]

If there are 45 beads, with a ratio of $1:4$
Then,
$\frac{45}{5}=9$
Then if $\frac{1}{4}=\frac{9}{x}$
Then $x=9*4$
Therefore, $x=36$
Meaning, there would be a ratio of 36 beads to 9 beads

Answer:

Hope this helps :)

Step-by-step explanation:

8(x - 2) = 2x + 8

y+9 = -2(y + 1)

value of x in 8(x - 2) = 2x + 8

x=4

substitue

y+9=−2(y+1)

value of y y+9=−2(y+1)

y= - 11/3 or 3.66...

x=4

y=4 (I rounded 3.66)

Which line has the same slope as the line passing through (- 4, -1) and (-1, 8)

Troyanec [42]

The slope is [ 8 - (-1) ] / [ -1 - (-4) ] = 9 / 3 = 3;

The line has the equation: y - 8 = 3( x + 1);

y - 8 = 3x + 3;

y = 3x + 11.
