4 0

Answer:

9

Step-by-step explanation:

How I got my answer:

a+ bc turns into 7 + 4 x 1/2

First, you do 4 x 1/2 which equals 2 ( 4/1 x 1/2 = 2)

Then, you add 7 and 2

=9

Let AB = 24, AC = 10 and BC = 26.
nata0808 [166]

Answer:

a) 24

b) 10

c) 12/13

d) 5/13

e) 12/5

Step-by-step explanation:

a) We can see that the leg opposite <C is AB, and we are given AB = 24

b) We can see the leg adjacent to <C is AC, and we are given that AC = 10

c) The trig function sine is equal to

\frac{opposite}{hypotenuse}

The opposite, AB, is 24, and the hypotenuse, BC, is 26. We can plug those numbers in:

sin(c) = \frac{24}{26} = \frac{12}{13}

d)The trig function cosine is equal to

\frac{adjacent}{hypotenuse}

The adjacent, AC, is 10, and the hypotenuse, BC, is 26. We can plug those numbers in:

cos(c) = \frac{10}{26} = \frac{5}{13}

d)The trig function tangent is equal to

\frac{opposite}{adjacent}

The opposite, AB, is 24, and the adjacent, AC, is 10. We can plug those numbers in:

tan(c) = \frac{24}{10} = \frac{12}{5}

Solve the linear system by graphing y = x - 1 y =3x - 9
Zielflug [23.3K]
I think is
y = x - 1y = 3x - 9
y - y = x - 3x = -9
0 = - 2x = - 9
