Answer: ⅗ or 3/5
Step-by-step explanation:
Complete y2 - y1 over x2 - x1 with your given points:
-4 - (-1) = -3
_____ ___ (Remember that two negatives equal to a positive)
-2 - 3 = -5
Gradient = y/x
Gradient = 7--2/7-4 = 9/3 = 3
Gradient = 3x
We're looking for a gradient that's double 3x
6x
<h2>A. y = 6x + 1</h2>
Answer:D 19 cm
Step-by-step explanation:
N₁*$0.10 + n₂*$0.25 = $2.25
n₁ + n₂ = 12
-----------
This means that:
n₁ = 12 - n₂
And:
(12 - n₂)*$0.10 + n₂*$0.25 = $2.25
12*$0.10 - n₂*$0.10 + n₂*$0.25 = $2.25
$1.20 + n₂*$0.05*(5-2) = $2.25
$1.20 + n₂*$0.05*3 = $2.25
$1.20 + n₂*$0.15 = $2.25
n₂*$0.15 = $2.25 - $1.20
n₂*$0.15 = $1.05
n₂ = ($1.05)/($0.15)
n₂ = 7
If n₂ = 7:
n₁ + 7 = 12
Therefore, n₁ = 5.
