The answer has to be in y-intercept form. Which is y=mx+b and b can also be neg. y=mx-b. The m is your slope and b is your y-intercept. So A’s slope counting from 3 on the y axis to 1 on the x-axis which is down 2 over 1 so it will be -2/1. And your y intercept is 3. The equation is y=-2x+3. For B its the same thing but no graph. Remember that slope is RISE over RUN. So since the number is on the bottom of the line the rise is 4 and the run is 1. So in this case 10 is your y-intercept. Which means you equation is y=4x+10.

(w+14)/(4w+6)=(3)/(4) show work plz

sergey [27]

Answer:

w = -1.44 and w = -14.06

Step-by-step explanation:

That "(3) / (4)" in (w+14)/(4w+6)=(3)/(4) looks fishy. Assuming that you really meant 3/4, then we have (w+14)/(4w+6)=3/4.

Mult. both sides by 4 to remove the fraction: 4(w+14)/(4w+6) = 3.

Multiply out (w+14)/(4w+6): 4w^2 + 6w + 56w + 84. Combine the w terms, obtaining 4w^2 + 62w + 84. Then the original equation becomes:

4w^2 + 62w + 84 = 3, or 4w^2 + 62w + 81 = 0.

This is a quadratic equation, with a = 4, b = 62 and c = 81. The two roots (values of

w) are as follows:

-62 plus or minus √(62^2-4(4)(81)

----------------------------------------------------------

8

-62 plus or minus √(2548) -62 plus or minus 50.48

w = ------------------------------------------- = ---------------------------------------

8 8

Simplifying, we get w = -1.44 and w = -14.06

Suppose a triangle has two sides of length 2 and 3 and that angle between these two sides is 60 degrees. What is the length of t

Rudiy27

Answer:

The measure of the third side is $\sqrt{7}\ units$

Step-by-step explanation:

we know that

Applying the law of cosines

$c^2=a^2+b^2-2(a)(b)cos(C)$

where

C is the angle between side a and side b

we have

$a=2\ units\\b=3\ units\\C=60^o$

substitute

$c^2=2^2+3^2-2(2)(3)cos(60^o)$

$c^2=13-(12)(\frac{1}{2})$

$c^2=13-6$

$c^2=7$

$c=\sqrt{7}\ units$
