22-7-7-7=1 this will show that you can subtract 7 three times from 22 and have a remainder of 1.

When f(x) = 0.5|x is graphed on a regular coordinate grid, the graph forms

PtichkaEL [24]

Answer:

A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.

Morgarella [4.7K]

Answer:

Ashley bought 6 rainbow stickers and 8 balloon stickers for her little sister.

Step-by-step explanation:

Let the number of rainbow sticker be x and number of balloon stickers be y.

Cost a single rainbow sticker= 6 cents

Cost a single balloon sticker= 4 cents

Cost a single x rainbow sticker= 6 cents × x

Cost a single y balloon sticker= 4 cents × y

Total number of stickers bought = 14

x + y =14 ..[1]

Total money spend on stickers = 68 cents

6x cents+4y cents=68 cents

$6x+4y=68$ ...[2]

Putting value of from [1] into [2];

x = 14 - y

$6(14-y)+ 4y=68$

$84-6y+4y=68$

$-2y=-16$

$y=\frac{-16}{-2}=8$

x = 14 -y =14 - 8 = 6

Andre constructs the image of line n under a dilation centered at point O that is not on line n. Becca construct a different ima

GenaCL600 [577]

<em /><u><em /></u>I think that both lines will show only 1 line because 1 line will be on top of the other. I believe this because both lines are dilated with its center at point O which does not lie on line n. Whatever dilation Andre uses may also be the dilation used by Becca since their lines centered at point O. Both lines will have the same slope and share the same coordinates.
