Answer: the formula is r you have it right there
Step-by-step explanation:
Answer: The system of equations represents the constraints in this situation are:
s + h = 40
$18s + $14h = $700
The above equations are known as simultaneous equations. 40 scarves and hats were sold, this can be represented with this equation:
number of hats sold + number of scarves sold = 40
s + h = 40
The total amount made from the sales is the sum of the total amount made from the sale of the hats and the total amount made from the sale of the scarves. This can be represented with this equation:
($18 x s) + ($14 x h) = $700
Step-by-step explanation:
Answer:
1/3(4√2/2- 5)
-1/3(4√2/2 + 5)
Step-by-step explanation:
2(3x+5)² -16=0
2(3x+5)²=16
(3x+5)² = 4²/2
3x+5= 4/√2 ⇒ 3x= 4/√2- 5 ⇒ x= 1/3(4√2/2- 5)
3x+5= -4√2 ⇒ x= -1/3(4√2/2 + 5)
8 - 1 = 7
7 - 9 = -2
7 divided by -2 is -3.5
The slope is -3.5 now we need to find the y intercept.
To find the y intercept do -3.5 times 7 and you get -24.5.
Next do 8- -24.5 and you get 32.5 which is the y intercept.
The equation would be y = -3.5x + 32.5
Answer:
A
Step-by-step explanation:
<h3><u>Commutative Property</u></h3>
- (a + b) + c = c + (a + b)
<u>(40.50 + 56.95) + 25.75</u> ; <u>25.75 + (40.50 + 56.95)</u> correctly represent the situation using the commutative property.
