Please Help Fast Algebra 1

Alex Ar [27]

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 :

$m = \frac{y2 - y1}{x2 - x1}$

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

-6h plus 4 - 3plus h equals 11

olga55 [171]

$- 6h + 4 - 3 + h = 11$
So we start by combining like terms;
$- 6h + h = - 5h$
$4 - 3 = 1$
Now we have;
$- 5h + 1 = 11$
We then subtract 1 from both sides;
$- 5h + 1 = 11$
$- 5h = 10$
Then we divide both sides by 5;
$- 5h = 10$
$- 5h \div - 5h = h$
$10 \div - 5h = - 2$
Leaving the final answer to be h = -2
