Answer: Alejandra gave $60 to the cashier.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given.
We have to subtract to the amount that Alejandra paid(x) the sum of the costs of each product [videogame (24), controller (13) and memory card (169] and the total tax (3). the expression must be equal to the amount received in change.
Mathematically speaking:
x -(24+13+16+3) = 4
Solving for x:
x - 56 =4
x = 4+56
x =60
Alejandra gave $60 to the cashier.

Answer:
C(5, −5), D(−4, −5)
Step-by-step explanation:
9 across
A(-4, 5) ————————— B(5, 5)

D(-4, -5) ————————— C(5, -5)
Automobile insurance: 809.50
comprehensive coverage: 64
Based on the note:
subtract 64: 809.50 - 64 = 745.50
multiply by 150% : 745.50 x 1.5 = 1,118.25
add 64: 1,118.25 + 64 = 1,182.25
The new total is 1,182.25
Answer:
an equation of a line
Step-by-step explanation:
This is an equation of a line. Lets walk through it.
y=1/3x+2
This is to find out what the Y coordinate would be when X is plugged in. So, if x was 6, you would take 1/3 of 6 to get 2, and add 2. The y intercept would be 4, since y=1/3(6)+2, y=2+2, y=4
Y=1/3x+2
This is what the slope is. If the slope is negative (ie. -3/4) the greater the x intercept the lower the y will be. (so if I had x=4 for a slope of -3/4, that would be y=-3/4(4)+2, y=-3+2, y=-1) But if the slope is positive (ie. 1/3) the greater the x value the greater the y value as well. (see graph attached below for positive)
Y=1/3x+2
This is the Y intercept. (This is NOT the y coordinate. This is only the coordinate of y if x=0) This number tells you where the Y intercept is. If it adds, the y intercept is positive. If it subtracts, the y intercept is negative.
Sorry if these explainations dont make sense. But, here is the graph for y=1/3x+2
