Answers

Answer: x = 40

The equation you would write would be 2x + x + 60 = 180.

This is because you have to add all the angles inside the triangle in order to get 180°. Then, you solve the equation.

2x + x + 60 = 180
Add all the like terms.
3x + 60 = 180
Subtract 60 on both sides.
3x = 120
Divide 3 on both sides.
x = 40

Step-by-step explanation:

Because you should put the gh with gh, 2  is equivalent to 2 (so the 2 disappeared) and you only have 8-7=1 plus 2=3.

Answer: The given expression is 8g^2h-7gh+2

The degree of 8 g^2 h is 2, 1

The degree of - 7 g h is 1

The degree of 2 is 0

But the degree of expression will the highest degree of the indivisual expression of above i.e 3.

Answers

Answer:

m = 1 and b = 5/7

Step-by-step explanation:

Take two of the points. The first two. (7, 5) and (8, 6).

We can find the slope using:

y2-y1/x2-x1

We can sub in the values:

6-5/8-7 = 1/1 = 1

So the slope is 1

now, putting this into y=mx+b, and using one of the coordinates from earlier, we can solve for b:

5 = (1)(7) + b

b = 5/7

Therefore, m = 1 and b = 5/7

Hope this helps!

Answers

Step-by-step explanation:

To write the equation in LaTeX in form y = ab^x  or [tex]ab^x[/tex] for y = abx .........(1)

(a) LaTeX: y=3\sqrt{4^{2x}}  y = 3 4 2 x can be written in mathematical form as

[tex]y=3\sqrt{4^{2x}}[/tex] ; y = 342x

on comparing with equation (1) we get a =3 and b =4

⇒y = 34^x or [tex]34^x[/tex]

(b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 can be written in mathematical form as

[tex]y=\frac{\sqrt[3]{5^{3x}}}{2}[/tex] ; y = 342x

on comparing with equation (1) we get a =0.5 and b =5

⇒y = [tex]\frac{1}{2}5^x[/tex]

(c)LaTeX: y=8^{x+2} y = 8 x + 2 can be written in mathematical form as

[tex]y=8^{x+2}[/tex]

on comparing with equation (1) we get a =64 and b =8

y = [tex]64 . 8^x[/tex]

(d)LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}  can be written in mathematical form as

[tex]y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}[/tex] = [tex]3^{x+1}[/tex] = [tex]3 . 3^x[/tex]

on comparing with equation (1) we get a =3 and b =3

y = [tex]3 . 3^x[/tex]

2x+8y=56 on a 10x 10 grid

Answers

Answer:

Step-by-step explanation:

Simplifying

2x + -8y = 56

Solving

2x + -8y = 56

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8y' to each side of the equation.

2x + -8y + 8y = 56 + 8y

Combine like terms: -8y + 8y = 0

2x + 0 = 56 + 8y

2x = 56 + 8y

Divide each side by '2'.

x = 28 + 4y

Simplifying

x = 28 + 4y

39,000 over 12 = ?? Also, show your work so I can do the rest of these myself

Answers

Answer:

3,250

Step-by-step explanation:

Let's go from left to right, using multiple of 12 times a power of 10 in the process.

What is the closest multiple of 12,000 (12 * 10^3) to 39,000 without going over? That's 3 (36,000). That's the thousands digit in this answer.

12,000 * 3 = 36000

39000 - 36000 = 3000

What's the closest multiple of 1,200 (12 * 10^2) to 3,000 without going over? That's 2 (2,400). That's the hundreds digit.

1,200 * 2 = 2,400

3,000 - 2,400 = 600

What is the multiple of 120 (12 * 10) closest to 600 without going over? That's 5 (600, it's even!). That's the tens digit. Since it goes evenly, 0 is the ones digit.

120 * 5 = 600

600 - 600 = 0.

The answer to 39,000 over 12 is 3,250.

The pendulum swings at an arc of 30 cm and its successive swings reduced to 10% of the previous swings. What is the total distance travelled by the pendulum after 5 swings? This problem is an example of what sequence?

Answers

Answer:

[tex]S_g= 33.333cm[/tex]

Step-by-step explanation:

From the question we are told that

Arc of 30 cm

10% reduction after each swing

Generally sum of geometric sequence is given by the equation

    [tex]S_g=\frac{a(1-r^n)}{1-r}[/tex]

Mathematically solving for total distance traveled we have

    [tex]S_g=\frac{30(1-(0.10^5)}{1-(0.10)}[/tex]

    [tex]S_g=\frac{30}{0.9}[/tex]

Therefore the total distance traveled  by the pendulum after 5 swings

    [tex]S_g= 33.333cm[/tex]

How would you solve this?

Answers

Answer:

For the equation, you should subtract 2x on both sides to get -y = -2x - 4.  Flip the y's negative sign to get a proper function which is y = 2x + 4.  The y-intercept is at (0, 4) and each unit will move two units up along the x-axis.

What are the y values for the equation : y=0X-4 if x=-3

Answers

Note: Your equation expression seems a little unclear. So, I am assuming that your expression is

y = x - 4

The solution steps would anyway still clear your concept so that no matter what you can solve whatever the expression it is because the procedure remains the same.

Answer:

The value of y = -7 if x = -3

Step-by-step explanation:

Assuming the given the expression

[tex]y = x - 4[/tex]

Given that we have to find the value of y if x = -3.

so substituting x = -3 in the equation

[tex]y = x - 4[/tex]

[tex]y = (-3) - 4[/tex]

[tex]y = -3-4[/tex]

[tex]y = -7[/tex]

Therefore, the value of y = -7 if x = -3
