Answer: i have the answer to the first one good luck on your assignment!

Step-by-step explanation: 1. 12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric

she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds

each dog bed sells for 17.50.....5 * 17.50 = 87.50

87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==

Answer: I'm gonna answer the last one

Step-by-step explanation:

First lets add up Rosalva

1.5+0.69+1.04+2.1=5.33

Next lets do Jake

1,450+1,590+1204+1,977=6,221

We have two different measurements, we want them to be the same. We are gonna change Rosalva. One kilometer equals 1,000 meters. If u use the g o o g l e calculator it says that 5.33 kilometers equals 5330 meters. since u need to show work just multiple 5.33 by 1,000.

Last we need to find the difference soooooooo 6,221-5330=891 meter difference :)

Which point lies on the graph of the function shown below?
horsena [70]

Answer:

(1, 1)

Step-by-step explanation:

We need to evaluate the given expression for each of the x-values and check if the y-value agrees with the y-value given in the pairs:

1) First point (-1,3): use x=-1 and check if y results in "3":

y=-x^2+4x-2\\y=-(-1)^2+4(-1)-2\\y=-1-4-2=-7

we obtained y=-7, so the point (-1,3) is Not on the graph of the function

2) Second point (0,2): use x=0 and check if y results in "2":

y=-x^2+4x-2\\y=-(0)^2+4(0)-2\\y=-0+0-2=-2

we obtained y=-2, so the point (0,2) is Not on the graph of the function

3) Third point (2,-2): use x=2 and check if y results in "-2":

y=-x^2+4x-2\\y=-(2)^2+4(2)-2\\y=-4+8-2=2

we obtained y=2 (and not -2), so the point (2,-2) is Not on the graph of the function

4) Fourth point (1,1): use x=1 and check if y results in "1":

y=-x^2+4x-2\\y=-(1)^2+4(1)-2\\y=-1+4-2=1

we obtained y=1 (the same y as in the given coordinate pair), so the point (1,1) IS on the graph of the function

25 POINTS!
lora16 [44]

Answer:


Step-by-step explanation:

I can only do the first one, and then only by brute force. If both numbers can be the same, then David would write 143143

143 * 143 = 20449

7 * 20449 = 143*143. It is the only answer that came up from 100 to 999.

If I get the second one, I'll put it in the comments. But I can only do it by brute force as well, if I can do it at all.
