Hugh compró algunas revistas que cuestan $ 3.95 cada uno y algunos libros que cuestan $ 8.95 cada uno. se gastó un total de $ 47.65.si hugh compró 3 revistas, cuántos libros se compró? la ecuación que modela el problema es 3.95m 8.95b = 47,65, dondem es el número de revistas yb es el número de libros.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man
