Answer:

First option

Step-by-step explanation:

In y = mx + b, m is the slope and b is the y-intercept

Plug in m, and coordinates of D and solve for b

Answer:

Substitute the slope and the coordinate of D into the equations and solve for b for each equation

Step-by-step explanation:

The equation for a line is y = mx+b

where m is the slope and b is the y intercept

We know m

We have a point (x,y)

We can substitute into the equation and solve for b

Simplify (3s^8)^-5 write your answer using only positive exponents. help please!!
loris [4]

Answer:

1 / ( 243s^40 )

Step-by-step explanation:

For this problem, we need to know that a negative exponent simply can be rewritten in the opposing part of the fraction, for this case, the denominator.  So we can simplify as shown:

(3s^8)^-5

= 1 / (3s^8)^5

= 1 / 3^5 * s^8^5

= 1 / 243 * s^40

= 1 / ( 243s^40 )

Cheers.

Answer:

Angle 1 = Angle 2 = 5y -23            (Vertically opposite)

We can see that we have a triangle in the figure

Since the sum of all angles of a triangle is 180,

<em>(2x + 13) + (47) + (5y -23) = 180</em>

<em>2x + 5y + 37 = 180</em>

<em>2x + 5y = 143</em>

5y = 143 -2x -----------------(1)

Assuming l and m to be parallel

<em>angle 1  = 3x (corresponding angles)</em>

<em>5y - 23 = 3x </em>

<em>From equation (1)</em>

<em>143 -2x - 23 = 3x </em>

<em>120 = 5x </em>

x = 24 ---------------------- (2)

Using (2) in (1)

<em>5y = 143 - 2(24)</em>

<em>5y = 143 - 48</em>

<em>5y = 95</em>

y = 19

Therefore,

x = 24

y = 19
