We can use substitution method to solve for this system of equations. We calculate as follows:
<span>2x – 6y = –14
-6y = -14 -2x
y = x/3 + 7/3
</span>5x – 3y = –11
5x – 3(x/3 + 7/3) = –11
5x - x + 7 = -11
4x = -11 -7
4x = -18
x = -9/2
y = -9/2(3) + 7/3
y = 5/6
Answer:
The answer would be D, -(-4)
Step-by-step explanation:
This is because two negatives equal a positive.
Answer:
a = 3
b = 2
Step-by-step explanation:
(x - 3)² - 9 + 7 = 0
(x - 3)² - 2 = 0
x - 3 = ± √2
x = 3 ± √2
And they want the answer in the formula so a = 2 and b = 2
Answer:
no
Step-by-step explanation:
no because if you multiply $329.50 by .6 you get $197.7, then with the additional 40% (.4) you end up having to pay $79.08
Answer:
<h2><em><u>
12 is the total area</u></em></h2>
Step-by-step explanation:
A of triangle = 1/2 * b * h
b = 6
h = 2
2 * 6 * 0.5
= 12 * 0.5
<h2><em><u>
= 6</u></em></h2>
A of square = l * w
2 * 2
<h2><em><u>
= 4</u></em></h2>
A of Triangle = 1/2 * b * h
2 * 2 * 0.5 =
4 * 0.5
<h2><em><u>
= 2</u></em></h2>
2 + 4 + 6
= 6 + 6
<h2><em><u>
= 12</u></em></h2>
