3 0

Answer:

Yes, because if you substitute 10 for r in the equation and simplify, you find that the equation is true.

Step-by-step explanation:

\frac{r}{4}  = 2.5 \\ lhs =  \frac{r}{4}  \\  =  \frac{10}{4}  \\  = 2.5 \\  = rhs \\  \therefore \:  \frac{r}{4}  = 2.5 \\

Solve the equation: <br><br> 9 (x − 9)−3 = −4 (2x + 4)<br><br> 4<br><br> -4<br><br> 100<br><br> 68
Nina [5.8K]

Answer:


Step-by-step explanation:

Applying BODMAS here;

We first solve what is in the brackets:

9x - 81 -3 = -8x - 16

We then put the like terms together:

9x + 8x = -16 + 81 + 3

We then do the addition:

17x = -16 + 84

We then do the subtraction:

17x = 68

Simplifying this gives:

x = \frac{68}{17} = 4

What is the perimeter of this shape?
Fudgin [204]

Answer:

87 feet

Step-by-step explanation:

Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:

30+9+12+9+9+9+9=87 feet

Hope this helps!

Write a function g whose graph represents a reflection in the y-axis of the graph of f(x)=−3+|x−11|.
Jet001 [13]

The function g whose graph represents a reflection in the y-axis of the graph of f(x)=−3+|x−11| is; g(x) = x + 8

<h3>How to solve transformation problems?</h3>

Transformations are used to change the position of a function from one point to another.

Now, we are given the function as;

f(x) = -3 + |x - 11|

To reflect the function above across the y-axis, we will make use of the following transformation rule: (x, y) → (-x, y)

Thus, since we are given f(x) = -3 + |x - 11|, applying the transformation rule above gives us;

f(-x) = -3 + |-1(x - 11)|

Removing the absolute sign gives us;

f(-x) = -3 + x + 11

f(-x) = x + 8

Thus, the function g whose graph represents a reflection in the y-axis of the graph of f(x)=−3+|x−11| is; g(x) = x + 8
