C=m/3.
This equation is saying the cost (c) equals the minutes (m) on the phone out of 3 people
Answer:
20
Step-by-step explanation:
f(x)= 3x²-2x+4
f(-2)=3×(-2)²-2(-2)+4
=3×4)+4+4
=12+4+4
=20
Answer:
48%
Step-by-step explanation:
Data provided in the question:
Selling price of the gaming card = 9.99
Amount paid for the card i.e purchasing cost = 6.75
Now,
The markup percentage is calculated as:
Markup =
or
Markup =
or
Markup =
or
Markup = 0.48 × 100% = 48%
We can find the value of x through a proportion. Since these two triangles are similar, their sides are in proportion.
4 is to 12 as 5 is to x
Remember to say 12, not 8! 8 is only part of the whole side. We can also simplify 4 is to 12 to 1 is to 3.
1/3 = 5/x
Cross multiply
x = 15
Hope this helps!
y =
x + 3
The equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange - 2x + 3y = 9 into this form
add 2x to both sides
3y = 2x + 9 ( divide all terms by 3 )
y =
x + 3 ← in slope-intercept form
