Step-by-step explanation:

Answer:

1. Y = 1/2x + 2

2. X = 20 - Y = 12

Step-by-step explanation:

1. The other formulas clearly don't fit.

2. Simply fill in 20 for X and solve the formula.

Answer:

5. We can already tell from the looks of it that she is using a different number for pi throughout her answers. Therefore it is C

6. 2 x 3.14 x 4.9 = 30.772 rounded would be 31, C is your answer.       *formula of circumference:* pi(3.14 or 22/7 whatever they tell you to use for pi) x 2(its just always there when finding circumference) x radius(half of diameter or already given radius)

7. Let's just find the value of X on the top.

51(given degree) + 90(right angle degree) + X = 180(straight line degree)

51 + 90 + x = 180

141 + x = 180

-141      -141

X = 39

39 is the same to x beneath so therefore the value of x is 39 degrees.

Answer:

15

Step-by-step explanation:

The Pythagorean's Theorem states that a^2 + b^2 = c^2, so 81 + 144 = 225, and 225 square rooted is 15.

Answer:

15

Step-by-step explanation:

So, to find the hypotenuse you must use the pythagreons theorm:

A^2+B^2=C^2

Now, we knowt hat A and B is the side lengths.(9 and 12)

The hyoptenuse is C.

So, lets plug in our values for A and B, and find C:

A^2+B^2=C^2

=

9^2+12^2=C^2

Now lets square each number except for C, since its a unknown value:

81+144=C^2

Now combine the 144 and 81:

225=C^2

Finally, square root both sides so C^2 becomes C:

15=C

So the answer for the hyotenuse is 15!

Hope this helps!

Step-by-step explanation:

just use pythagoraus theorem

Answer:

x ≈ 4.5

Step-by-step explanation:

First, use the Pythagorean theorem to find the missing variable with side 8 and hypotenuse 10.

a² + b² = c²

a² + 8² = 10²

Square the variables

a² + 64 = 100

Subtract 64 from both sides.

a² = 36

Take the square root of both sides.

a = 6.

Now we can find the other triangle and we now know that one side is 4 and the hypotenuse is 6.

a² + b² = c²

x² + 4² = 6²

Square the variables.

x² + 16 = 36

Subtract 16 from both sides.

x² = 20

Square root. (refresh if you don't see this part.)

[tex]x=\sqrt{20}\\\text{Factor out a 2.}\\x=2\sqrt{5}[/tex]

Converted to decimal to the nearest tenth, the answer is

x = 4.5.

Now let's prove it.

[tex]a^2+b^2=c^2\\\text{Substitute variables.}\\(2\sqrt{5})^2+4^2=6^2\\\text{Factor the 2 in.}\\(\sqrt{20})^2+4^2=6^2\\\text{Square the variables.}\\20+16=36\\\text{Add.}\\36=36[/tex]

Answer:

y=7/4x–5/2

Step-by-step explanation:

You must find the slope first, let it be m

[tex]m = \frac{y2 - y1}{x2 - x1} \\ = \frac{8 - ( - 6)}{6 - ( - 2)} \\ = \frac{14}{8} \\ = \frac{7}{4} [/tex]

then insert tu the formula y=mx+c to find the c (c is the intercept of y axis) choose any point that you want. i use (6,8)

[tex]y = mx + c \\ 8 = \frac{7}{4} (6) + c \\ c = - \frac{5}{2} [/tex]

so the equation is

[tex]y = \frac{7}{4} x - \frac{5}{2} [/tex]

Answer:

Replace all occurrences of y with 2x−1 in each equation.

0=0

y=2x−1

Remove any equations from the system that are always true.

y=2x−1

Answer:

12.5%

Step-by-step explanation:

The spinner has 8 equal sections, numbered 1, 2, 3, 4, 5, 6, 7, and 8. The only number greater than 7 is 8. There is 1 number greater than 7.

P(greater than 7)  =  

1

8

Write your answer as a decimal. Then convert your answer to a percentage.

1

8

=  0.125  =  12.5%

P(greater than 7) = 12.5%

Answer:

6

Step-by-step explanation:

Answer:

In this expression the highest degree of polynomials = 6 due to because see in the one of terms constains the power of x to be as 4 and y to be as 2 Therefore the highest degree of polynomials in all terms is 4+2 = 6
