Solution:
We are going to find the distance between points A -4; 2, B 3; -5 :
d = √ (xb - xa) 2 + (yb - ya) 2 =
= √ (3 - (-4)) 2 + (-5 - 2) 2 =
= √72 + (-7) 2 = √49 + 49 =
= √98
= 7√2 ≈ 9.899494936611665
Answer:
=−6x^4+5x^3
Step-by-step explanation:
Since 308 people can visit each day, and there's 8 shows each day, we just multiply 308 by 8.
308*8 = 2464 people.
Answer:
3. y = 1
4. y = 3, x = 12
Step-by-step explanation:
Like the question says, we'll be using substitution, so for the first one, we'll be substituting the value of x into the equation
x = 5
3x- 5y = 10
3 (5) - 5y = 10
15 - 5y = 10
5y = 15 - 10
5y = 5
y = 1
For the next one, it's a similar idea, except the value of x has the variable y in it, which is fine, as there is still only one value in the equation we'll be solving:
x = 4y
x + y = 5
4y + y = 5
5y = 15 (we needed to collect like terms to simplify)
y = 15/5
y = 3
we still have to find x, to this, we substitute the value of y into any of the equations:
x = 4y
x = 4 (3)
x = 12
Hope this helps,

7/8 x 3/8 = 21/64
In simplified form is 21/64 because that’s how far it can go since its already simplified
