Nickels is 0,05 of dolar - n
dimes is 0,1 o dolar -d
quarters is 0,25 of dolar -q
dimes =2nickels
d=2n
quarters=2dimes
q=2d=4n
12,5=n(0,05)+2n(0,1)+4n(0,25)
12,5=0,05n+0,2n+n
12,5=1,25n
n=10
q=4n=40
There are 40 quarters
The measure of the intercepted arc (a) is twice the measure of the inscribed angle intercepting it (b or 25°). The measures of the inscribed angles are all the same: b = 25°.
The appropriate choice is D. 25
Answer =-3 or -3/1
You can either do rise/run
Or you can find two points on the line and do (y2-y1)/(x2-x1)
Two points on the line are (-1,2) and (-3,-4)
X1=-1 Y1=2
X2=-3 Y2=-4
(y2-y1)/(x2-x1) = (-4-2)/(-3-(-1)) =(-6)/(-3+1)
=-6/-2 = -3
So slope =-3/1 or -3 (same thing)
$19.95x +$3
x stands for number of tickets purchased.
$19.95(5) + $3
$99.75 + $3
$102.75 for 5 tickets
Answer:
y = x + 2
Step-by-step explanation:
As the equation of a line is in the form y = mx + c:
Step 1 - Calculate the y intercept
This can be done by looking at the y coordinate where x = 0:
y = mx + c
In the picture, the y intercept is 2 so:
y = mx + 2
Step 2 - Calculate the slope
This can be calculated by:
Get two sets of coordinates:
(0, 2) and (2, 4)
Calculate the changes by subtracting from one another:
So the gradient is 1, meaning the equation of the line is:
Hope this helps!
