Answer:
y = 5x - 17
Step-by-step explanation:
y = mx + c
m = the gradient/slope = 5
y = 5x + c
Substitute (3, -2) into the equation above to find c.
-2 = 5(3) + c
-2 = 15 + c
-2 - 15 = c
-17 = c
y = 5x - 17
Answer:
$0.94 per pound
Step-by-step explanation:
To find the unit rate, make an equation and simplify it.
<em>2 pounds = $1.88</em>
<em>1 pound = ($1.88 ÷ 2) $0.94</em>
Hence, It costs <em>$0.94 per pound</em>
Answer:
Step-by-step explanation:
Add 
and 
on both sides.
Add or subtract like terms.
Divide 
on both sides.
is the independent variable now.
Circumference=2πr
=2*3.14*105
=659.4cm
Answer:
81°
Step-by-step explanation:
By the outside angle theroem, we know that 2 * angle APC is differece of arcs DC and AB.
Angle APC = 27° so the difference is 54°
Arc DC = 27°, so Arc AB = 27° + 54° or 81°.
