Answer:
-8
Step-by-step explanation:
Start by putting a dot on the number line at -3. As we are to subtract 6, start at -3 and move 6 units to the left, arriving at -9. Finally, recognizing that -(-1) = +1, move 1 unit to the right from -9, ending up at -8.

Kevin and Randy Muise have a jar containing 68 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $8.00. How many of each
type of coin do they have?
The jar contains
quarters
9514 1404 393
Answer:
23 quarters45 nickelsStep-by-step explanation:
Let q represent the number of quarters. Then the number of nickels is 68-q, and the number of cents in the jar is ...
25q +5(68 -q) = 800
20q +340 = 800 . . . . simplify
20q = 460 . . . . . . . . subtract 340
q = 23 . . . . . . . . . . . divide by 20; this is the number of quarters
68-q = 45 . . . . . . . find the number of nickels
The jar contains 23 quarters and 45 nickels.

Rearrange the equation y+5=3/4(x-12) into slope-intercept form.
PLEASE show work for brainliest
The equation y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12) can be rearranged into slope intercept form as y = [tex]\frac{3}{4}[/tex] x + (-14).
What is the slope intercept form of a line ?
The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.
An equation is given which is :
y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12)
If we multiply by 4 on both sides , we get :
4y + 20 = 3x - 36
or
4y = 3x - 56 -- -- -- -- --- ---- ----- ----- --- --- --- Equation 1
We know that the slope intercept form of a line is given by :
y = mx + c
So , to change the above equation into slope intercept form we must divide equation 1 by 4. So , the rearranged equation will be :
4y / 4 = (3/4 x ) - (56 / 4)
y = [tex]\frac{3}{4}[/tex] x + (-14)
Therefore , the equation y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12) can be rearranged into slope intercept form as y = [tex]\frac{3}{4}[/tex] x + (-14).

3x = 1/9 what is x
Please respond quick
Please help me with this answer ASAP
Step-by-step explanation:
first let's bring the equation into "normal" form :
x - 2y = 2
-2y = 2 - x
2y = x - 2
y = x/2 - 1
so, the slope of this line is 1/2 (the factor of x - that is always the case in all lines).
a parallel line must have the same slope, of course.
so, its equation is
y = x/2 + b
now, b will be different to the -1 of the original equation, or the lines are identical.
it is the point of interception of the line through the y-axis (x = 0).
we get this by using the coordinates of the given point (4, -3).
so,
-3 = 4/2 + b = 2 + b
b = -5
therefore, the formula for the parallel line is
y = x/2 - 5

Graph the following system of inequalities.
y<2x+1
y<-x-1
9514 1404 393
Answer:
X.
Step-by-step explanation:
The inequalities tell you the graph is below a solid line that goes up to the right, and below a dashed line that goes down to the left. The upward sloping line has a slope of 2, so is steeper than the downward sloping line that has a slope of -1.
The colored portion will be in the bottom quarter of the X made by the crossing lines. The appropriate graph is X.

$39.98 selling price and tax rate 4.5%
Answer:
Step-by-step explanation:
The marked price is 39.98
The tax is 4.5%
That means that the tax is added on to the marked price to get the selling price.
One way to do is is to multiply by the tax factor.
The tax factor is 1 + 4.5/100 = 1.045
So the Selling price = 39.98 * 1.045
Selling price = 41.78 rounded to 2 decimal places.
The more standard way of doing this is to multiply the tax by the marked price and add that on to the marked price to get the selling price.
39.98 * 4.5/100 = 1.7991
39.98
1.7991 Add
41.7791
The difference comes in where you do the rounding. The second way to do this has no rounding. If you convert this to money, the answer will be 41.78, just as the first way's answer.

emiliano de las cosas que no y que no sonThe depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour. If
the depth after 6 hours of draining is 8 feet then write an equation for the water depth, d, as a function of the
amount of time it's been draining, t, in hours.
The linear function for the depth of water after t hours is given by:
[tex]d(t) = 17 - 1.5t[/tex]
The format of a linear function is given as follows:
[tex]d(t) = d(0) - at[/tex]
In which:
d(0) is the y-intercept, which is the initial value.a is the slope, which is the rate of change.The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour, which means that [tex]a = -1.75[/tex], thus:
[tex]d(t) = d(0) - 1.5t[/tex]
The depth after 6 hours of draining is 8 feet, which means that when [tex]t = 6, d(t) = 8[/tex]. This is used to find d(0).
[tex]d(t) = d(0) - 1.5t[/tex]
[tex]8 = d(0) - 1.5(6)[/tex]
[tex]d(0) = 17[/tex]
Then
[tex]d(t) = 17 - 1.5t[/tex]
