Step-by-step explanation:
Which one is the height?¿
The formula is
b1+b2 divided by 2 times the height
That's the best I can do for you atm atleast.
10% of $20 is 2 so the shirt would be $18 before tax
To find x-intercept substitute 0 for y and solve for x
-6x + 3(0) = -7
Simplify
-6x=-<span>7
</span>Divide each side by -6
-6x ÷ -6 = -7 ÷ -6
x = 7/6
X = 7/6 is your x intercept
-------------------------------------
To find y-intercept substitute 0 for x and solve for y
<span>-6(0)+3y=-7
Simplify
</span><span>3y</span>=-<span><span>7
</span></span><span>Divide each side by 3
3y </span>÷ 3 = -7 ÷ 3
<span>y = -7/3
Y = -7/3 is your y-intercept
</span>
