Angle 1 and angle 2 are supplementary angles. m<1 is 4y + 7, and m<2 is Sy + 4. Find m<2.

Step-by-step explanation:

First, we should define supplementary angles.

Supplementary angles are angles that add up to 180 degrees.

Since 1 and 2 are supplementary and we know their values, we just set them equal to 180 degrees

(

4

y

+

7

)

+

(

9

y

+

4

)

=

180

Now just solve for one variable

13

y

+

11

=

180

13

y

=

169

y

=

13

Now the question asks for m<2, which is

9

y

+

4

So we just plug in

9

⋅

13

+

4

=

121

So m<2 is 121

Hello,

If R(4,0) is the given point and m=5 the slope,

y-0=5(x-4)==>y=5x-20 is the reduced form
and 5x-y-20=0 is the standard form

What is the true solution In 20+In 5=2 In x?
S_A_V [24]

Answer:

x = 10

Step-by-step explanation:

Using the rules of logarithms

• log x + log y ⇔ log(xy)

• logx^{n} ⇔ n log x

• log x = log y ⇒ x = y

Given

ln20 + ln5 = 2 lnx , then

ln(20 × 5) = lnx^{2}

ln 100 = lnx^{2}, hence

x² = 100 ( take the square root of both sides )

x = 10
