Problem 11

------------------

Explanation:

We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b

A = (1/2)*b*h

2A = b*h

b*h = 2A

h = 2A/b

================================================

Problem 12

------------------

Explanation:

The number n is increased by 2 to get n+2

Then we divide by 5 to get (n+2)/5

This is set equal to 14 to get the equation (n+2)/5 = 14

Solving the equation would look like this

(n+2)/5 = 14

n+2 = 5*14 .... multiply both sides by 5

n+2 = 70

n = 70-2 .... subtract 2 from both sides

n = 68

================================================

Problem 13

------------------

Explanation:

We'll replace every copy of x with -3 and simplify

-2x + 5 > 13

-2*(-3) + 5 > 13

6 + 5 > 13

11 > 13

The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.

Therefore, x = -3 is not a solution.

Answer:

4x + 3 = 11

4x = 11 - 3

4x = 8

x = 8 ÷ 4

x = 2

3x - 5 = 7

3x = 7 + 5

3x = 12

x = 12 ÷ 3

x = 4

8x - 5 = -37

8x = -37 + 5

8x = -32

x = -32 ÷ 8

x = -4

7(x - 3) = 21

7x - 21 = 21

7x = 21 + 21

7x = 42

x = 42 ÷ 7

x = 6

Answer:

2550.5

Step-by-step explanation:

We have a circle and are asked to find the area.

We know the diameter already, but the formula to find area requires a raidus, which is unknown to us yet.

To find radius, all you need to do is follow [tex]\frac{d}{2}[/tex]. D being diameter.

D = 57.

[tex]\frac{57}{2}= 28.5[/tex]

The radius is 28.5, now do the formula of area.

[tex]A = \pi *r^2[/tex]

[tex]A = \pi *28.5^2[/tex]

[tex]28.5^2[/tex]

[tex]812.25[/tex]

[tex]A=\pi *812.25[/tex]

[tex]A=3.14 * 812.25[/tex]

[tex]A = 2550.465[/tex]

Now we need to round to the nearest tenths, since 6 is the knowledge that we round up, round up.

[tex]2550.5[/tex]

Answer:

The expression is not true, if that's the question

Step-by-step explanation:

Order of operations is multiply and divide before add and subtract from left to right...also note that grouped expressions in parentheses happen first as well

multiply and divide are of equal order to each other

add and subtract are if equal order to each other

right side

They are not equal

(2.25,-0.5)

Step-by-step explanation:

If you were to graph the equations, they intersect at the points 2.25, and -0.5.

Answer:

(9/4, -1/2)

Step-by-step explanation:

We already know the y-coordinate of the solution:  It is y = -1/2.  To find the x-coordinate, we substitute -1/2 for y in y = 2x - 5:

-1/2 = 2x - 5

Clearing out fractions, we multiply all three terms by 2:

-1 = 4x - 10, or

4x = 9

Then x = 9/4

The solution is (9/4, -1/2)

Answer:

Step-by-step explanation:

Graph  has been transformed from the graph of y = x³ by a horizontal shift of 4 units to the right then by a reflection over the x-axis, and 5 units upward of vertical shift.

A function from a set X to a set Y assigns to each element of X exactly one element of Y.

The given function is y = -(x-4)³ + 5.

Let us use algebraic methods to understand the transformation of the graph of this function.

First, we can observe that the parent function is y = x³ has been transformed to y = -(x-4)³ by replacing x with (x-4).

This transformation gives  a horizontal shift of the graph of 4 units to the right.

then negative sign in front of the function reflects the graph over the x-axis, resulting in an upside-down graph.

Finally, the entire graph is shifted vertically upward by 5 units, as observed  by the constant term +5 in the equation.

Hence,  the graph  has been transformed from the graph of y = x³ by a horizontal shift of 4 units to the right then by a reflection over the x-axis, and 5 units upward of vertical shift.
