They are both variables. General dependent variables. Meaning each ones values change depending on the others.
Answer:
Lori spends <u>9 minutes</u> on sketching
th of a sketch.
Step-by-step explanation:
Given equation:

where
number of minutes Lori spends on sketching
and
number of sketches Lori makes.
We need to calculate the time spent by Lori in sketching
of a sketch.
So we know the value of
as
represents number of sketches and in this situation Lori has sketched only a fraction of a painting.
So we plugin
in the equation and calculate
which is time spent by Lori sketching
th of a sketch.


∴
minutes (Answer)
∴ Lori spends 9 minutes on sketching
th of a sketch.
Answer:
x = -3, 6
Step-by-step explanation:
First, add 18 to both sides
x² - 3x - 18 = 0
+ 18 + 18
x² - 3x = 18
Add 9/4 to both sides because that is the square of half of -3
x² - 3x + 9/4 = 18 + 9/4
Multiply both sides by 4 to get rid of the fractions
(x² - 3x + 9/4 = 18 + 9/4)4
4x² - 12x + 9 = 72 + 9 = 81
Factor the left side of the equation
(2x - 3)² = 81
√(2x - 3)² = √81
Because of the square root, this will result in a positive number and a negative number
2x - 3 = 9
2x - 3 = -9
For both equations, add 3 to both sides then divide by 2
2x - 3 = 9
+ 3 +3
2x = 12
2x/2 = 12/2
x = 6
2x - 3 = -9
+ 3 + 3
2x = -6
x = -3
Answer:
Plug in your x value into your equation --> y=2x+3
Step-by-step explanation:
Do this for each x-value that's missing the y- value :)
We are given
The current exchange rate is 2 guilders for every 3 florins
so,
2 guilders = 3 florins
now, we can find for 1 guilders
so, we get

now, we can multiply both sides by 17

now, we can simplify it

so, option-A........Answer
