Graph y greater than or equal to (x+2)^2

Mathematics
1 answer:
katovenus [111]2 years ago
3 0

Answer:

See attached image

Step-by-step explanation:

The graph of y\geq (x+2)^2 is not the one shown on the picture. Although the highlighted are (above the curve) is correct, since that corresponds to the y-values larger than those of the parabola, the problem is that in the picture given, the actual trace of the parabola (which corresponds to the equality y=(x+2)^2, is shown with dotted trace - which by convention indicates that the trace is NOT included.

Since the inequality symbol in our inequality DOES contain the equal sign (larger than OR EQUAL to), the parabola's trace should be represented with a solid line. (see attached image)

4x + 5y = 22<br> 7x - 3y = -32
lana66690 [7]

Answer:

x = -2

y = 6

Step-by-step explanation:

i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out

   12x + 15y = 66

+  <u>35x - 15y = -160</u>

   47x = -94

x = -94/47

x = -2

substitute -2 for 'x' to solve for 'y':

4(-2) + 5y = 22

-8 + 5y = 22

5y = 30

y = 6

1200/180 = <br><br><br><br><br> (can someone please help me I'm desperate)
ASHA 777 [7]

Using a calculator, 1200/180 = 6.67 approximately

If you use long division, then you'll get what you see in the diagram below

The 6's go on forever after the decimal point, but if you round to two decimal places, then you'll get that approximate value of 6.67

---------------

If you want a remainder, then 1200/180 = 6 remainder 120

You can think of it like you having 1200 cookies and 180 friends. Each friend will get 6 whole cookies and there will be 120 left over as the remainder.

What is least perimeter of a rectangle with an area 32 square feet
Aleks04 [339]
If you have a rectangle with an area of 32 square feet, it means that the sides are 
A=L x W,   32= 8*4, where
 L=8, W=4
other options are
 L=16, W=2 and the last one is
 L=32, W=1 
You need to find the least perimeter , and you know that the perimeter is P= 2(L+W)
Perimeter (1)= 2(8+4)=2*12=24
Perimeter(2)= 2(16+2)=2*18=36
Perimeter (3)=2(32+1)=2*33=66

The least perimeter is 24, with the sides L=8 and W=4

A smaller square park has an area of 3600 square meter. what is the length of one side of the park
Julli [10]
Divide the area by 4 because a square is 4 sides. Once divided take your answer and multiply by 4 if it's the same as the area that's your answer.
