Sal brought $7.50 to the fair and karma brought $8.75 to the fair. which expression shows the total amount they brought? a) $8.75 - $7.50 = $16.25 b) $8.75 + $7.50 = $15.25 c) $8.75 - $7.50 = $1.25 d) $8.75 + $7.50 = $16.25

Ahas the coordinates (–4, 3) and b has the coordinates (4, 4). if do,1/2(x, y) is a dilation of △abc, what is true about the image △a'b'c'? check all that apply. ab is parallel to a'b'. do,1/2(x, y) = the distance from a' to the origin is half the distance from a to the origin. the vertices of the image are farther from the origin than those of the pre-image. a'b' is greater than ab.
