Answer:
The woman bought 2 items at $12 each.
Step-by-step explanation:
Given that a woman bought a number of items for $ 24, and she realized that if she had bought 4 more items for the same money, she would have paid $ 8 less per item, to determine how many Items did she buy the following calculation must be done:
X = 24
X + 4 = 24
24/2 = 12
24/6 = 4
12 - 4 = 8
Therefore, the woman bought 2 items.
Answer:
Option C.
Step-by-step explanation:
It is given that the dilation rule is 
. It means the center of dilatation is point Q and scale factor is 2.5.
Scale factor is the ratio of distance from center to the image of a point and distance from center to the corresponding point.
It is given that QU=4 and scale factor = 2.5.
Multiply both sides by 4.
We know that
The distance between U' and U is 6 units.
Therefore, the correct option is C.
Answer:
y intercept is 3.5 or 3 1/2
Step-by-step explanation:
y=mx+b
substitute the ordered pair (-1,4) in place for y and x in the equation; substitute the slope of -1/4 in place of m to solve for "b"
4= -1/4(-1) +b
4= 2/4+b
subtract 2/4 from both sides
b= 3 2/4 which reduces to 3 1/2 or in decimal form 3.5
