Answer: y = 2
Step-by-step explanation:
we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:
since x=2y+1,
we can say that:
(2y+1)+2y=9
then we solve this equation,
first we expand the brackets- 2y+1+2y=9,
then we combine like terms- 4y+1=9
then we take 1 away from both sides- 4y=8
then we divided both sides by 4
y=2
Hope this helps xx
Answer:
Step-by-step explanation:
first you need to put the equation in y=mx+b form
y-3=(-1/2)(x+4)
y-3= (-1/2x)+4
y=-1/2x+1
then you just graph
the y intercept is 1 and the slope is -1/2 so it’s going to be a negative graph and it starts from 1 on the y axis
0 to 12 bags is the correct answer, 12 bags will put her at exactly $40. This means she cant have more than 12 bags.
Do 23 times 18, and 14 times 14. Multiply the answers.
In order to get the answer for this question you need to times 2 by 10, which equals 20 since it's $2 for each guest. That now leaves her with $20. $26+$20 <u>equals </u><u>$46</u> for the total cost of the retirement party.
