Answer:
The answer is B.
Step-by-step explanation:
The question ask us to find an equation for the cost of a fill-up and a car wash. Firstly, we have to form 2 coordinates from the table and find the gradient :
Let Tank Size be x and Total Cost be y,
Any 2 coordinates,
Let (11,21.45) be (x1,y1) & (15,28.25) be (x2,y2),
m = (28.25-21.45)/(15-11)
= 6.8/4
= 1.7
You can form equation using slope-form, y = mx+b, then substitute m value and any coordinates into the equation :
Let m= 1.7 & (17,31.65),
y = mx + b
31.65 = 1.7(17) + b
31.65 - 1.7(17) = b
b = 2.75
y = 1.7x + 2.75
Answer:
yes
Step-by-step explanation:
yeah you put all the distances together and then you get the area.
Answer:
38 degrees
Step-by-step explanation:
Since the degrees in a triangle add up to 180, all you need to do is to find the other 2 angles in the triangle and subtract their sum from 180. Since you have the exterior angles, you can just find their supplements to get the two missing angles.
180-134=46
180-84=96
180-(46+96)=38
Answer: The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.
Step-by-step explanation:
The equations would be 100+2r and 80+5s. These equations would show how much Henry and Yolanda make each day, based on how much they sell.
