I must assume that your graph is that of a straight line, and that the end points of the line are P and B, and (finally) that T is between P and B.  If these assumptions are correct, then the length of the line segment PB connecting points P and B is 15 + 10, or 25.

HELP ME! <br>Please, I will give brainliest and extra points :) Thank you
Arte-miy333 [17]

Answer:

solution set of f(x) = g(x) is x∈{0,1}


Step-by-step explanation:

For all exponential functions b^x,

b^0 is always 1, and b^1 is always b.


f(x) = -3/4 x + 2

g(x) = (1/4)^x + 1

g(0) = 2, f(0) = 2

g(1) = 5/4, f(1) = 5/4

Find the difference (20m+3)-(7m-5)
xz_007 [3.2K]

Answer:

Simplifying

(20m + 3) + -1(7m + -5) = 0

Reorder the terms:

(3 + 20m) + -1(7m + -5) = 0

Remove parenthesis around (3 + 20m)

3 + 20m + -1(7m + -5) = 0

Reorder the terms:

3 + 20m + -1(-5 + 7m) = 0

3 + 20m + (-5 * -1 + 7m * -1) = 0

3 + 20m + (5 + -7m) = 0

Reorder the terms:

3 + 5 + 20m + -7m = 0

Combine like terms: 3 + 5 = 8

8 + 20m + -7m = 0

Combine like terms: 20m + -7m = 13m

8 + 13m = 0

Solving

8 + 13m = 0

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 13m = 0 + -8

Combine like terms: 8 + -8 = 0

0 + 13m = 0 + -8

13m = 0 + -8

Combine like terms: 0 + -8 = -8

13m = -8

Divide each side by '13'.

m = -0.6153846154

Simplifying

m = -0.6153846154Step-by-step explanation:
