Answer:
28
Step-by-step explanation:
Givens
Game 1: 30
Game 2: 18
Game 3: 28
Game 4: x
Solution
(30 + 18 + 28 + x) / 4 = 26 Multiply both sides by 4
4* (30 + 18 + 28 + x) / 4 = 26 * 4 The 4s on the left cancel
30 + 18 + 28 + x = 104 Add the 3 other numbers together
76 + x = 104 Subtract 76 from both sides.
76-76+x = 104-76 The 76s on the left disappear.
x = 28
Answer
in the next game he must score 28 points to average 26
It seems like there are answer choices but you forgot to post them. If you want to simplify then
2*sqrt(7) - sqrt(28) = 2*sqrt(7) - sqrt(4*7)
2*sqrt(7) - sqrt(28) = 2*sqrt(7) - sqrt(4)*sqrt(7)
2*sqrt(7) - sqrt(28) = 2*sqrt(7) - 2*sqrt(7)
2*sqrt(7) - sqrt(28) = (2-2)*sqrt(7)
2*sqrt(7) - sqrt(28) = (0)*sqrt(7)
2*sqrt(7) - sqrt(28) = 0
So the whole complicated expression simplifies to 0 (zero)
This is because sqrt(28) = 2*sqrt(7) when you simplify sqrt(28)
Side Note: "sqrt" is shorthand for "square root"
Answer:
A.
![y - 5 = -2(x-6)](https://tex.z-dn.net/?f=y%20-%205%20%3D%20-2%28x-6%29)
Negative reciprocal gives you the perpendicular slope so negative reciprocal of 1/2 is -2.
Then apply point-slope form.
B. The answer is x = 6.
The midpoint of JK is
![\left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) = \left( \frac{8+ 4}{2}, \frac{4 + 4}{2} \right) = \left(6,4\right)](https://tex.z-dn.net/?f=%5Cleft%28%20%5Cfrac%7Bx_1%20%2B%20x_2%7D%7B2%7D%2C%20%5Cfrac%7By_1%20%2B%20y_2%7D%7B2%7D%20%5Cright%29%20%3D%20%5Cleft%28%20%5Cfrac%7B8%2B%204%7D%7B2%7D%2C%20%5Cfrac%7B4%20%2B%204%7D%7B2%7D%20%5Cright%29%20%3D%20%5Cleft%286%2C4%5Cright%29)
The line that goes through JK is just a horizontal line
because the y-coordinate does not change. So its perpendicular bisector is the vertical line that goes through the x-coordinate of the midpoint, that is,
.
1. You want to distribute the equation like this: 8+(2)(x)+(2)(−6)+x—> 8+2x+-12+x.
2. Combine like terms to this equation.
8+2x+-12+x—>(2x+x)+(8+-12)—> 3x+-4
3. You get the answer which is 3x-4.
