6 times the sum of y and 11
Gelneren [198K]

Answer:

6y+66

Step-by-step explanation:

write the problem out, placing 6 on its own, and the sum of y and 11 inside a pair of parentheses after the 6.

6(y+11)

then, just use the distributive property and multiply each term inside the coefficients by six. you'll get 6y+66 as your final answer.

if your teacher says that the final answer is not supposed to have variables in it, then we'll need a bit more information.

Solve the system of equations<br> .625x - y = -9.625<br> -65x - y = -5
Ivan
Here, 0.625x - y = -9.625
y = 0.625x + 9.625

Substitute the value of y in 2nd equation, 
-65x - (0.625x + 9.625) = -5
-65x - 0.625x -9.625 = -5
-65.625x = 9.625 - 5
x = -4.625/65.625
x = -0.070

Now, substitute it in first equation, 
-65(-0.070) - y = -5
4.58 + 5 = y
y = 9.58

In short, Your Answer would be: (-0.070, 9.58)

Hope this helps!

Write an equation that can be used to find the value of x. The perimeter of rectangle: 32 Length of the other side: 4
Sati [7]

Answer:

x=12

Step-by-step explanation:

32=2(4+x)

distribute 2.  

32=8+2x

subtract 8 from both sides.  

32=8+2x

-8   -8

24=2x

divide by 2 on both sides

24/2=2x/2

12=x

Quadrilateral ABCD has vertices A(–2, 4), B(1, 3), C(2, –3), and D(–3, –1). Graph quadrilateral ABCD and its image after a rotat
marshall27 [118]

Answer:

(-3 , 1)(-2,4) (4,5) (2,0)

Step-by-step explanation:

Rotation around center (x₀ , y₀), counterclockwise rotation θ degree

x₂ = (x₁-x₀)cosθ - (y₁-y₀)sinθ + x₀  

y₂ = (x₁-x₀)sinθ + (y₁-y₀)cosθ + y₀

A(-2.4) -> counterclockwise rotation 90°

F(x,y): x = (-2+1)cos90° - (4-2)sin90° + (-1) = -3

          y = (-2+1)sin90° + (4-2)cos90° + 2 = 1

F (-3 , 1)

Use the above formula to calculate other 3 points: (-2,4) (4,5) (2,0)
