C i just took the test hope this helps:-)
The sales tax would be 75 cents i think because .05 x14.90 is 745 and you round to the nearest hundreth so 75 i think i really hope i helped
Answer:
x= 1.5, y= 3.5
or x= -5, y= 10
Step-by-step explanation:
Let's solve by substitution.
Label the two equations:
y= 2x² +6x -10 -----(1)
y= -x +5 -----(2)
Substitute (2) into (1):
2x² +6x -10= -x +5
2x² +6x +x -10 -5= 0
Simplify:
2x² +7x -15= 0
Factorise:
(2x -3)(x +5)= 0
2x -3= 0 or x +5= 0
2x= 3 or x= -5
x= 1.5
Now that we have found the value of x, we can find the value of y through substitution.
Substitute into (2):
y= -1.5 +5 or y= -(-5) +5
y= 3.5 or y= 10

Answer:
first, you distribute
-2x-12=8x-48+2
then, you combine like terms
-2x-12=8x-46
next, you subtract 8x from both sides
-2x-8x-12=-46
You add 12 to both sides.
-10x=-34
finally, you divide -10 from both sides
x=34/10 or x=17/5

Answer:
false
Step-by-step explanation:
The statement being made is false. Dollar markdowns actually represent the difference in price that exists between the original price of the product and the current price that the item is selling for. This is what happens when a store places a discount on an item or places a sale on it. Dollar Markdown is the actual difference in dollar/currency value while Markdown percentage is the difference in percentage with regards to the original price.
