Answer:
15x-8=0
x=8/15
Step-by-step explanation:
To find the percentage of the discount first of all we will calculate the price discounted.
for that we will subtract the new price from the original price
225 - 90 = 135
Now to find the percentage discount we will use the following method of dividing the difference in both prices by original price multiply it with 100
135/225 x 100 = 60
This means that the percentage discount was 60% on this dress.
Step-by-step explanation:
The slope of the above line = -2
slope of the line perpendicular to the above line = 1/2
If it passes through point (4,-3) , it's equation
A = 1, B = -2 and C = -10
A+B+C= 1+(-2)+(-10)
= 1-2-10
= 1-12
= -11
In each graph, take a any point on either side and substitute in the inequality. Then check if it satisfies the inequality.
For graph 1, take a point (0,0).
substituting it we get,
y>4x-2 ⇒ 0>-2. This is true yet the region where (0,0) is, is shaded. So, wrong graph.
For graph 2, take point (0,0).
y>4x-2 ⇒ 0>-2. This is true but againt the region is shaded. so, wrong graph.
For graph 3, take point (0,0)
y>4x-2 ⇒ 0>-2. This is true. Since the point (0,0) is in this region, which is not shaded, it means that this is the required region. The correct graph is graph 3.
Answer:
Constant of proportionality
K= 16.5 gallons per minute
Step-by-step explanation:
Time t (minutes) Water g (gallons)
For t= 1, g= 16.50,
for t= 1.5 ,g= 24.75
For t= 2,g= 33
Let the function be
Gallons g= k(time t)
Where k is the constant of proportionality
16.5= k(1)....for when t= 1
24.75= k(1.5) ..for when t= 1.5
Solving gives
8.25=k(0.5)
8.25/0.5= k.
16.5 = k
K= 16.5 gallons per minute
