What is the equation of this graphed line?

Eva8 [605]

Answer:

y = -9/8x + 7

Step-by-step explanation:

Slope-intercept form is:

y = mx + b

Points given:

(0, 7) and (8, -2)

y-intercept is

b = 7 as per the first point

And the slope is:

m = (-2 - 7)/(8 - 0) = -9/8

So the line is:

y = -9/8x + 7

HELP WILL GIVE BRAINLIEST FOR ANSWER QUICKLY PLEASE HELP

Helen [10]

Answer:

We have sinθ = 12/13

The method here is to figure out the value of θ

Using a calculator sin^(-1)(12/13) =67.38°

67.38° is in quadrant 1 so we must substract 67.38° from 180° wich is π

180-67.38= 112.61° ⇒ θ= 112.61°

Now time to calculate cos2θ and cosθ using a calculator

cosθ = -5/13
cos2θ = -0.7

The values we got make sense since θ is in quadrant 2 and 2θ in quadrant 3

Find x. Leave answers in simplified radical form. (Step by step)

just olya [345]

Answer:

$\sf x = 4\sqrt{2}$

Given:

adjacent: 4 cm
hypotenuse: x cm
angle: 45°

using cosine rule:

$\sf cos(x) = \dfrac{adjacent}{hypotenuse}$

$\sf cos(45) = \dfrac{4}{x}$

$\sf x = \dfrac{4}{cos(45)}$

$\sf x = 4\sqrt{2}$

Answer: Mrs, William takes 18 treats to school.

Step-by-step explanation:

Given: When the crispy treats have cooled Mrs. Williams cut theme into 30 equal pieces .

She give 2/5 to her son, then the number of treats ahe give to her son = $\frac{2}{5}30=12$

Then, the number of treats Mrs. Williams take to school = $30-12=18$

Hence, Mrs, William takes 18 treats to school.
