3x + 5y = -2
3x + 7y = 26
Subtract first equation from second
2y = 28
y = 14
Plug it in
x = -24
Answer:
-15.96
Step-by-step explanation:
A conjugate is a binomial with the sign inside changed. So the conjugate of (1/5 + 4i) is (1/5 - 4i)
Set the original and the conjugate next to each other and F.O.I.L. Multiply the first numbers of each binomial, the 1/5 and the 1/5 to get 1/25. This is the "F."
Multiply the outer members, the 1/5 and the 4i to get - 60i. This is the "O."
Multiply the inner numbers ( the + 4i and the 1/5) to get + 60i. This is the "I."
Multiply the positive 4i and the negative 4i to get 16i squared
The positive 60i and the negative 60i cancel each other out.
The i squared changes into - 1. This makes the 16 negative.
Add 1/25 to - 16 to get - 15.96
Answer:
2200 Square Yards
Step-by-step explanation:
Dimension of the Youth Soccer Field = 110 yards long and 60 yards wide.
- Therefore Area of the Youth Soccer Field = 110 X 60 =6600 Square Yards
Dimension of the professional soccer field =110 yards long and 80 yards wide.
- Area of the professional soccer field = 110 X 80 =8800 Square Yards
The difference in their Area = 8800-6600=2200 Square Yards
Therefore, the professional soccer field has an area of 2200 Square Yards more than the youth soccer field.
The expression that represents the product of negative three-fourths x and –8x is 6x^2
<h3>How to determine the equivalent expression?</h3>
The statement is given as:
the product of negative three-fourths x and –8x
Rewrite properly as:
-3x/4 * -8x
Divide 4 and 8 by 4
-3x * -2x
Multiply -3 and -2
6x * x
Multiply x and x
6x^2
Hence, the expression that represents the product of negative three-fourths x and –8x is 6x^2
