If xy=0 then assume taht x and/or y=0
remember differnce of 2 perfect squares
a^2-b^2=(a-b)(a+b)
factor
6x^2-24=0
6(x^2-4)=0
6(x^2-2^2)=0
6(x-2)(x+2)=0
set to zero
x-2=0
x=2
x+2=0
x=-2
x=2 and -2
A is answer
Use Desmos insert y=0.4x into the calculator
Mid section: 15 * 7 = 105
left triangle: 1/2 * 4 * 7 = 14
right triangle: 1/2 * 6 *7 = 21
total: 105 + 14 + 21 = 140 in^2
Answer:
<h2>y = -11</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, b)</em>
<em />
We have the slope <em>m = 0</em> and the point (0, -11) → <em>b = -11</em>.
Substitute:
<em>y = 0x - 11 = -11</em>
<em>It's a horizontal line.</em>
Answer:
0.111
Step-by-step explanation:
1/9 as a decimal is 0.11111111 but rounded to 2 decimal places is 0.111.
Hope this helps :)
Have a good day / night
