A cookie costs 7 dollars and a mini cake costs 5 dollars
6x - 3.5 = -15.5
Add 3.5 to both sides
6x = -12
Divide by 6
x = -2

Answer:
Length of the volleyball court in drawing = 2 mm
Step-by-step explanation:
8 meter = 8 *1000 = 8000 mm
Scale factor = 1 : 8000
Length of the volleyball court in drawing = x
1 : 8000 :: x : 16000
x = 2 mm
<u>Answer:</u>
gradient = =
y-intercept =
<u>Step-by-step explanation:</u>
• The slope-intercept form of an equation takes the general form:
,
where:
m = slope,
c = y-intercept.
• We are given the equation:
To change this into the slope-intercept form, we must make y the subject:
[subtract from both sides]
⇒ [divide both sides by 3]
⇒
• Comparing this equation with the general form equation, we see that:
m =
c = .
This means that the gradient is , and the y-intercept is .
Answer:
Step-by-step explanation:
Neither are a function because they do not pass the vertical line test.
