Answer:
<h2>b = -9</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
The formula of a slope:

We have the points M(4, 3) and N(7, 12). Substitute:

Therefore we have the equation:

Put the coordinates of the point M to the equation:

<em>subtract 12 from both sides</em>

Answer:
the answer is to your equation is t=-0.8
$63.90 (total)
$5.40 (cards)
$11.70/per (bags)
$63.90 - $5.40 = $58.50
$58.50 / $11.70 = 5
She invited 5 guests (b).
Answer:
True
Step-by-step explanation:
(6³ * 3³)² = 18⁶
Multiply inside the parenthesis.
(18³)² = 18⁶
When you put powers to powers, they multiply, eg:
(x³)⁴ = x³°⁴ = x¹²
18⁶ = 18⁶
True.
Well, percent (%) means per hundred, and your number is 6. Therefore, you have 6 per hundred, or 6/100. Also, when you have a percent and want to convert it into a fraction, you must divide the percent by 100, so you could just put the six over 100 since the line between the numerator and denominator basically means division.
