Which inequality does this graph represent?

Mathematics
1 answer:
Neporo4naja [7]3 years ago
5 0

Based on the graph, the slope of the line is -1/2 because the slope is negative, as it is going down 1 unit and then 2 units to the left.

The y-intercept(b), where x = 0, is -1

So your equation is:

y ? -1/2x - 1

The shaded area is above the line, which means that y is greater than "-1/2x - 1"


The inequality is:

y ≥ -1/2x - 1

The answer is A

WILL MARK BRAINILEST!
Andru [333]
So it started at 180. After 4 more years it’s grown 188 cm to 368. If we estimate that it’ll grow 188 cm in another 4 years that puts our total to around 556. If we estimate and take off a year, it would probably be around 548 cm :)

A solar collector is 2,0 m long by 1,5 m wide. It is held in place
icang [17]

Answer:

The width of the frame is 0.0746 meters

Step-by-step explanation:

We are told that after the frame has been attached to the solar collector, the area that is left exposed is 2.5m^2  . As we see in the figure, the dimensions of this area are

(w-2x) and  (l-2x)

where x is the width of the frame.

The product of these dimensions must equal the exposed area:

(w-2x)(l-2x)=2.5m^2

Now since w=1.5m and l=2m we have:

(1.5-2x)(2-2x)=2.5

we expand this and solve for x using the quadratic formula:

4x^2-7x+3=2.5

4x^2-7x+0.5=0

we get two solutions:

x=1.6753

x=0.0746

We take the second solution i.e x=0.0746, because first one gives a width larger than the dimensions of the solar collector which cannot be possible.

Thus the width of the frame is 0.0746 meters.

Leslie and her family went out to dinner last night. The total bill was $78.44 after the 6% tax. How much was the bill before ta
sleet_krkn [62]

Answer:

$74

Step-by-step explanation:

you convert the percent to a decimal, .06, and try multiplying it with the numbers before 78, so you multiply it with 77, 76, 75, then 74, and when you multiply it with 74 you get 78.44.

Or you figure out the total amount money wise that the tax would count as and subtract that from 78.44.
