Answer:

3a + b = 54

3a + 9 = 54

3a = 54 - 9

3a = 45

3a / 3 = 45 / 3

a = 15

Help me solve this I wil give brainliest and 40 points
Verizon [17]

Answer:

Slope: -\dfrac{1}{2}

Equation: y=-\dfrac{1}{2}x+8

Step-by-step explanation:

The line of the best fit passes through the points (0,8) and (4,6).

If the line passes through the points (x_1,y_1) and (x_2,y_2) then the slope of the line is

\dfrac{y_2-y_1}{x_2-x_1}

Hence, the slope of the line of the best fit is

\dfrac{6-8}{4-0}=\dfrac{-2}{4}=-\dfrac{1}{2}

The equation of the line is

y=mx+b,

where m is the slope and b is y-intercept, so the equation of the line of the best fit is

y=-\dfrac{1}{2}x+8

Find the exact value of sin (-270 degrees).
user100 [1]
The exact value of sin (-270) is determined using the calculator in degrees mode. The answer is equal to 1. If the radians mode is used, -270 is equal to -2 pi/3. Hence using the calculator, we can verify that the answer is still 1. The value of -270 matters.

in a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b what is
puteri [66]

Answer:

5

Step-by-step explanation:

a=12 (height)

c=13 (hypotenous)

b=? (base)

By using Pythagoras theorm

We have, hypotenous sq=base sq+height sq

Let b =base SO, base sq=hypotenous Sq-height Sq

=>base Sq =13sq-12sq

Base Sq =169-144

Base Sq =25

Base =5 (shifting the sq)....

Hope it's helpful
