11c) find the values for a and b.
11c) what is the y-coordinate when x-coordinate is 1. (

11a) 2

11b) y=2x-3

11c) a = 7, b = 7

11d) y = -1

Step-by-step explanation:

11a) The line passes through the points (3,3) and (8,13), then its slope is

11b) The equation of the line is

11c) If point (5,a) lies on the line, then its coordinates satisfy the equation:

If point (b,11) lies on the line, then its coordinates satisfy the equation:

11d) If , then

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
