Answer:
Both have a negative slope.
Step-by-step explanation:
Because:
The equation has a negative slope (-2).
The table has a negative slope (-0.5):
(0,3). (2,2)
(X1, y1). (X2, y2)
M = y2-y1
_____
X2- x1
M = 2 - 3 -1
_____ = ___
2-0 2
Hope this helps! Have a great day!
39° or B that should be it
Answer:
the answer is the first one, Cara multiplied only 4 and 7 together and did not multiply 4 and 13
Step-by-step explanation:
if you look through the question you can see that Cara evaluated the (-4)^2 correctly because a negative multiplied by a negative gives you a positive thus (-4)*(-4)= 16, then next you can see that Cara subtracted 2 from 6 correctly because (6-2)= (4), and last but not least Cara did multiply 2 by 4 correctly because 2*4 or 2(4) =8 so as you can see the answer is the first one
Answer:
B
Step-by-step explanation:
For 11 1/2 gallons, he paid $36.80.
We need to find the cost per gallon.
First, converting 11 1/2 gallons to decimal, it is:
1/2 = 0.5
So, 11 1/2 is 11.5 gallons
So, Cost Per Gallon (last week) = ![\frac{36.80}{11.5}=3.2](https://tex.z-dn.net/?f=%5Cfrac%7B36.80%7D%7B11.5%7D%3D3.2)
There is 5% increase on this $3.20 per gallon. We find 5% of 3.2 and add it to 3.2 to find this week's cost per gallon.
<em>5% = 5/100 = 0.05</em>
<em>0.05 * 3.20 = 0.16</em>
<em>So,</em>
<em>3.20 + 0.16 = $3.36 per gallon</em>
<em />
Cost Per Gallon (this week) = $3.36
To buy 9 1/4 gallons it would take:
![3.36*9.25=31.08](https://tex.z-dn.net/?f=3.36%2A9.25%3D31.08)
<u>Note:</u> 1/4 = 0.25, so 9 1/4 = 9.25
It would cost $31.08 to buy 9.25 gallons this week
Correct answer is B
