<span>Simplifying y = 3x + -9 + 8x Reorder the terms: y = -9 + 3x + 8x Combine like terms: 3x + 8x = 11x y = -9 + 11x Solving y = -9 + 11x Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Simplifying y = -9 + 11x</span>

-2 times g(4) when g(x) =-x squared+(4x)-11
andrezito [222]

Answer:

+22

Step-by-step explanation:

Given g(x) = -x^2 + 4x - 11, g(4) is -(4)^2 + 4(4) - 11, or just -11.

Then -2 times g(4) = -2(-11) = +22

IRISSAK [1]
The amount one person will pay for a day is $4
The amount two people will pay for a day is $8
The amount Beth paid for 3 days is 4*3=12
The amount Maria paid for 3days is also 4*3=12
So to find the amount they will pay for 3days, add 12 and 12 to get 24.
The girls will pay $24 for the 3days.

Find 'x' in the following ​
Juli2301 [7.4K]

Answer:

x = 130

Step-by-step explanation:

Sum of all the angle of quadrilateral = 360°

50 + 45 + 35 + ∠ADC = 360

                130 + ∠ADC = 360

                         ∠ADC = 360 - 130

                         ∠ADC = 230

x = Reflex ∠ADC

  = 360 - 230

  = 130

Anyone know how to do this
Anton [14]

let

(hypotenuse ) c = 10 in

(perpendicular) a = 8 in

(base) b =?

By using Pythagoras theorem

c^2= a^2+b^2

(10)^2 = (8)^2 +(b)^2

100 = 64 +(b)^2

100- 64 = (b)^2

36 = (b)^2

√36 = b

6 = b

hence b= 6 in
