Answer:According to my calculations, an item with an original price tag of $54.50 that is marked down by 20% will have a sales price of $43.60 -- a savings of $10.90.
If you include the sales tax savings ($0.82 ) your total savings would add up to $11.72.
Step-by-step explanation:
Answer:
D.) 100 feet squared
Step-by-step explanation:
10 X 6=60
10 X 4=40
60+40=100
Answer:
slope is -1
Step-by-step explanation:
Slope of the line (m)=(y2 -y1)/(x2 -x1)
given
(x1, y1)=(-4 , 5)
(x2,y2)=(-7 , 8)
Now using the above formula
m =(8-5)/(-7-(-4))
m = (3)/(-7+4)
m= 3/(-3)
m=-1
therefore the slope of the line is -1
3x - 5y = 7
2x + 3y = 11
multiply the first equation by 2 and the second by -3:-
6x - 10y = 14
-6x - 9y = -33 Adding these 2 equations we eliminate the term in x:-
-19y = -19
y = 1
Substtute y = 1 in the first equation:_
3x - 5(1) = 7
3x = 12
x = 4
Answer is x=4,y=1 Answer
Second system of equation:-s
Here one equation is linear and the other is quadratic so we substitute fro y in the quadratic:-
From second equation y = 10x - 38, so substituting:-
10x - 38 = x^2 - 4x - 17
Gotta go right now . Sorry

<h3>Answer : (-2,11)</h3>

<h3>Known that</h3>
y = -2x² - 8x + 3
════════════════════
<h3>Way to do + explanation</h3>
#First, find the x coordinate first by using the formula of -b/2a
x = -b/2a = -(-8)/2(-2) = 8/-4 = -2
#After getting the x, find the y
y = -2(-2)² - 8(-2) + 3
y = -2×4 +16 + 3
y = -8 + 16 + 3
y = 11
So the vertex is
(-2,11)
