Answer:
x = -2.5
Step-by-step explanation:
Step 1: Write equation
-6.2 - 12.6x = 5.8 - 7.8x
Step 2: Solve for <em>x</em>
<u>Add 12.6x on both sides:</u> -6.2 = 5.8 + 4.8x
<u>Subtract 5.8 on both sides:</u> -12 = 4.8x
<u>Divide both sides by 4.8:</u> x = -2.5
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-6.2 - 12.6(-2.5) = 5.8 - 7.8(-2.5)
-6.2 + 31.5 = 5.8 + 19.5
25.3 = 25.3

Answer:
y - 2 = 5(x + 7)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 5 and (a, b) = (- 7, 2), hence
y - 2 = 5(x - (- 7)), that is
y - 2 = 5(x + 7)
Answer:
$344.04
Step-by-step explanation:
The markdown multiplies the price by (1 -40%) = 0.60.
The tax multiplies the price by (1 +10%) = 1.10.
The two factors applied to the price make the final price be ...
$521.28·0.60·1.10 = $344.04
The total cost of the surfboard was $344.04.
